Google Maps: your holiday sidekick

The holiday season is starting—which means time with friends, family, and lots of food. And though festivities may be a bit different this year, there are still creative, safe ways to celebrate and stay connected. No matter what you have in store for the holidays, these Google Maps tips can help you stay informed, stay connected and save time.

Stay informed even while running holiday errands and traveling

1. Check out how busy a place is:Popular times and live busyness information can tell you how crowded a place typically is on a given day or time—and even how busy it is right now. This is especially handy during the era of social distancing: Check out busyness on Maps before you head to a restaurant, store, business, or place to avoid holiday crowds and long waits.

2. (New!) Find the latest information about COVID-19: If you’re thinking about heading out of town to another city or state, you can use the COVID layer on Maps to quickly see how cases are trending in the area. You can also access quick links to authoritative local resources so you know at a glance if there are specific guidelines or restrictions in the area you’re visiting. 

3. Quickly understand safety precautions from a business: If you're eating out or getting a head start on your holiday shopping, you can easily learn more about what safety precautions a business is taking. Find out if they’re sanitizing between customers, if there's safety dividers at checkout and if they require staff to have regular temperature checks.

If you need to, connect safely

4. Share your ETA:If you need to see loved ones, let them know when they can expect you to arrive with you just a few taps. 

5. Don’t get lost: Planning to meet up with friends outdoors and at a distance? When a friend has chosen to share their location with you, you can easily tap on their icon and then on Live View to see where and how far away they are—with overlaid arrows and directions that help you know where to go.

Save time so you can spend more time enjoying the festivities 

6. (New!) Get more done on drives:If you’re road tripping home, using voice with Google Assistant driving mode in Maps helps make the ride more convenient and enjoyable while keeping your focus on the road. Starting to roll out today as a preview, Android users in the U.S. can now get call alerts from Assistant, answer or decline calls by simply using their voice, quickly review incoming messages across apps in one place, and play podcasts and songs from hundreds of media providers—all without leaving the navigation screen. 

7. (New!) Don’t let your food get cold: If you’re taking a low-key approach to the holidays this year and opting to order in instead of cooking an elaborate meal, Google Maps can help. When searching on your phone for restaurants nearby, you can easily sort by places that offer takeout or delivery and place your order directly from Google Maps. Now you can also see exactly when your order will be delivered or ready to pick up on the app’s home screen—because nobody likes cold turkey!

8. Search along your route:  If you’re on the road and realize you need to make a stop—say you’re running low on gas or need to pick up a last-minute item from the market—use Google Maps to search for gas stations, grocery stores, or other places along your drive so you can tackle your tasks without going too far out of your way.

Br(rr)ing on the holiday trends from Google Maps

This holiday, family gatherings will be smaller or take place virtually to make sure everyone stays safe and healthy. Indoor activities will move outdoors. And that international holiday vacation will potentially transform into an epic road trip to nearby attractions as you stop to sightsee at local hidden gems along the way. But even still, people are prepping to make classic holiday dishes, looking for ways to experience winter and finding new, safe ways to be together.

We’ve analyzed Google Maps data before and during the pandemic (for the purposes of this post, we analyzed data from March to October 2020) to see how people across the U.S. are getting ready for the holidays. Read on for top trends on how people are navigating, how they’re spending their time and what type of food they’re craving.

Dashing through the snow, in a ? or ?‍♀️ or ?

Across the country, Americans are opting for solo ways to get around safely. Unsurprisingly, driving continues to be the most popular mode of transportation, while interest in riding transit appears to be down by more than 50 percent. Cycling has emerged as a transit alternative–interest in cycling has increased 30 percent nationwide compared to pre-pandemic days, which is even higher than typical seasonal changes. Across all modes of transportation, we’re seeing people get directions to fewer new places, likely in an effort to social distance by sticking to tried and true spots versus exploring new places.

At the local level, transportation patterns are shifting:

  • While New Yorkers typically embrace public transit and Angelenos defer to driving–both cities have seen interest in driving increase by over 10 percent since the start of COVID. 

  • Cycling is up across the board, both in the East and the West. Cities with the biggest shift in cycling increases include Denver (+200 percent), Minneapolis (+150 percent), New York (+72 percent), Seattle (+65 percent) and Portland, OR. (+57 percent).

Popular times and live busyness information in Google Maps have always been essential holiday tools, helping you avoid unwanted crowds. These tools help you know in advance when places are going to be busy so you can save precious time and also social distance.

So if you find yourself in need of a caffeine fix to tackle your holiday errands, make sure to avoid picking up coffee on Saturday mornings at 10 a.m. when coffee shops across America tend to be most packed. And if you’re planning to shop for a holiday meal, stay away from the grocery store on Saturday afternoons between 1-3 p.m. when you’re likely to encounter long lines.

Google Maps Trends: Popular Times

Chestnuts (or turkey or stuffing) roasting on an open fire ? 

In the spring, Americans were optimistic about cooking at home–searches for “easy recipes” were at an all-time high. But as we approach the holiday season (and dishwashing fatigue sets in), people seem to want to order in. Interest in “takeout” on Maps has gained popularity by 306 percent compared to the beginning of the pandemic, and restaurant reservations booked directly on Maps have spiked more than 200 percent–likely because more restaurants are requiring them as they work to maintain safe capacity levels.

As for what people are eating, Mexican, Chinese, and BBQ are the most-searched cuisines across the country, and we’re seeing local noodle wars and more:

  • Seattlites and Denverites are pho lovers! Both cities have searched for “pho” twice as much as they’ve searched for “ramen.”

  • In Philadelphia, interest in “cheesesteak” has decreased by nearly 40 percent compared to early this year—suggesting that locals are expanding their food horizons or that tourists were the ones searching for this Philly classic.

  • Portlanders and New Yorkers are craving Thai. In both cities, interest in Thai food is up more than 100 percent compared to earlier in the year.

Spend time outdoors and deck the halls ?

From coast to coast, people are using Google Maps to have fun safely outdoors, searching for parks, waterfalls, beaches and gardens within driving distance. As the weather cools, searches for outdoor locations continue to remain higher than pre-pandemic. Even traditionally outdoorsy cities like Seattle (+56 percent), Los Angeles (+31 percent), and Denver (+135 percent) are looking for outdoor spots more than they were earlier this year.

When they’re not heading outside, people are sprucing up their homes. Searches for home and garden stores are increasing all around the country, with the highest spikes happening in Chicago (+77 percent), Detroit (+86 percent) and Cleveland (+96 percent).

No matter how you plan to spend the holidays, Google Maps is here to help you knock out your to-do list. Check out our favorite tips to keep your holidays as stress free as possible while staying safe, connected and organized.

An update on our efforts to help Americans navigate COVID-19

The COVID-19 pandemic has brought unprecedented challenges and emphasized how important it is for each of us to do our part to help find solutions. I’m sharing an update here on how Google is contributing to keep people safe and helping to get American businesses back up and running.

Contributing to economic recovery efforts

As I’ve written earlier, to help small businesses gain easier access to badly-needed capital, we founded the $170 million Grow with Google Small Business Fund alongside $10 million in Google.org grants, with an aim to help the most underserved small businesses, particularly those owned by women and minorities. In collaboration with Opportunity Finance Network, more than $53 million dollars of loans and Google.org grants have been allocated to community partners who are focused on serving rural, women, Black, Latino and Native borrowers, which helps American communities start to get back on their feet. Tires by Papi and Bailiwick Clothing Company are two such examples.


Of course, our greatest contribution continues to be developing products to help people stay informed, adapt and get through this pandemic. 

According to the Connected Commerce Council, nearly one in three small business owners report that without digital tools they would close all or parts of their business. To help small businesses, we rolled out many new, free product features earlier this year, so that they can inform their customers about things like takeout, delivery, no-contact delivery, or curbside pickup. Today, people can now find this information on Search and Maps for more than 2 million restaurants and retailers in the U.S.


Using Search and Maps, you can find information about businesses.

We’ve used Google’s Duplex technology to make calls to businesses and confirm things like temporary closures. This has enabled us to make 3 million updates to business information globally, which have been seen by people over 20 billion times in Search and Maps. 


To help people searching for jobs, we have stepped up to help in many ways. We added new relevant features in the U.S. like showing jobs that can be done remotely. Google Cloud has partnered with different states to help jobseekers: we assisted Rhode Island’s Virtual Career Center, a new platform that  connects thousands of jobseekers with jobs and employment services; worked with the State of Illinois to develop a 24/7 Virtual Intelligent Agent on the IDES website; developed a chatbot, in partnership with the New Jersey Office of Innovation to provide real-time answers to the 20 most popular unemployment questions. These are just some of the examples. 


We also transformed our free Grow with Google training to virtual formats and have already trained more than 1 million Americans on digital skills this year. The Google IT Support Professional Certificate—which takes beginner learners to entry-level jobs ready in under six months—has become the most popular certificate on Coursera during COVID-19.

Providing trusted information

Questions related to the pandemic are more searched than sports or music (and even elections) in every state. 

Top coronavirus related searches in the U.S. this month:

  1. Coronavirus symptoms

  2. Coronavirus update

  3. Coronavirus vaccine

Across the U.S. people are searching on Google to stay informed and adapt. In 47 states, the top coronavirus-related question during the last six months has been “How many cases of coronavirus in [my state].” Search interest for “online courses” reached an all-time high in April this year, as did searches for “unemployment,”compared to search trends over the last 15 years. 


During this time, we’ve also seen people seek out information to help them navigate their daily lives. For example, since the pandemic began, searches for “curbside pickup” have increased 13-fold compared to this time last year, while searches for “contact tracing” spiked 1,000 percent  in April and then reached an all-time high in May. 


In March, we launched Search Knowledge Panels so when people search for information related to COVID-19, they immediately see local guidance, information about symptoms, prevention and treatments. We’ve committed $250 million in Ad Grants to help government agencies provide critical information related to COVID-19. As of today we’ve served more than 100 million PSAs from local public health agencies, which have been seen by tens of millions of people across the U.S.


We also launched the Journalism Emergency Relief Fund to provide emergency funding for small and medium sized news organizations covering the pandemic. To date, we’ve distributed $9 million to U.S. newsrooms across all 50 states. 

Helping people make safe choices 

To help people make informed decisions about where to go, the COVID layer in Google Maps shows critical information about new cases in an area and how they’re trending. As of this month, our COVID-19 Community Mobility Reports, which are used by public health agencies and researchers around the globe, have been downloaded more than 16 million times. 

In May, we partnered with Apple to launch the Exposure Notifications System (ENS) and made it available to public health authorities around the world in their fight against COVID-19. Designed specifically and carefully to protect users’ privacy while helping public health authorities and governments manage countries’ re-opening, today 13 states and U.S. territories have built apps based on this ENS technology.

In a short time, COVID-19 has changed how people live their lives. We’ll continue to update our products and roll out initiatives to help people and American businesses find trusted information, adapt and manage economic uncertainty.

Stay informed and get around safely with Google Maps

People turn to Google Maps for accurate, fresh information about what’s going on in the world—especially so during the pandemic. Activities like picking up something from the store, going for a walk, or grabbing a bite to eat now require a significant amount of planning and preparation. At any given time, you may be thinking: “Does the place I’m headed to have enough room for social distancing?” or “What safety precautions are being taken at my destination?”


Today, as part of our Search On event, we’re announcing new improvements to arm you with the information you need to navigate your world safely and get things done.

Make informed decisions with new live busyness updates

The ability to see busyness information on Google Maps has been one of our most popular features since it launched back in 2016. During the pandemic, this information has transformed into an essential tool, helping people quickly understand how busy a place is expected to be so they can make better decisions about where to go and when. In fact, as people around the world adjusted to life during the pandemic, they used popular times and live busyness information more. We saw engagement with these features rise 50 percent between March and May as more people tapped, scrolled and compared data to find the best days and times to go places.   


We’ve been expanding live busyness information to millions of places around the world, and are on track to increase global coverage by five times compared to June 2020. This expansion includes more outdoor areas, like beaches and parks, and essential places, like grocery stores, gas stations, laundromats and pharmacies. Busyness information will surface in directions and right on the map—so you don’t even need to search for a specific place in order to see how busy it is. This will soon be available to Android, iOS and desktop users worldwide.

You’ll soon be able to see live busyness information without even searching for a place.

A new way to source up-to-date business information

It’s hard to know how a business’ offerings have changed during the pandemic. To help people find the freshest business information possible, we’ve been using Duplex conversational technology to call businesses and verify their information on Maps and Search. Since April 2020, this information has helped make more than 3 million updates, including updated hours of operation, delivery and pickup options, and store inventory information for in-demand products such as face masks, hand sanitizer and disinfectant. To date, these updates have been viewed more than 20 billion times.


Important health and safety information about businesses is now front and center on Maps and Search. You can quickly know what safety precautions a business is taking, such as if they require customers to wear masks and make reservations, if there’s plexiglass onsite, or if their staff takes regular temperature checks. This information comes directly from businesses, and soon Google Maps users will also be able to contribute this useful information.

See helpful information right from Live View

Getting around your city looks different these days. The stakes are higher due to safety concerns, and it’s important to have all the information you need before deciding to visit a place. In the coming months, people using Android and iOS devices globally will be able to use Live View, a feature that uses AR to help you find your way, to learn more about a restaurant, store or business.

Say you’re walking around a new neighborhood, and one boutique in particular captures your attention. You’ll be able to use Live View to quickly learn if it’s open, how busy it is, its star rating, and health and safety information if available,

Behind the scenes: popular times and live busyness information

If you’ve ever been in a rush to grab a quick bite, you may know the pain that comes along with finding out that the restaurant you chose is packed and there’s nowhere to sit. Or maybe you need to pick up just one item from the grocery store, only to find that the line is out the door—derailing your plans and causing you unnecessary stress. 


These problems were top of mind when Google Maps launched popular times and live busyness information—helpful features that let you see how busy a place tends to be on a given day and time or in a specific moment. This information has become a powerful tool during the pandemic, making it easier to social distance because you know in advance how crowded a place will be. Today, we’ll take a closer look at how we calculate busyness information, while keeping your data private and secure.

Popular times: making sense of historical busyness information

To calculate busyness insights, we analyze aggregated and anonymized Location History data from people who have opted to turn this setting on from their Google Account. This data is instrumental in calculating how busy a place typically is for every hour of the week. The busiest hour becomes our benchmark—and we then display busyness data for the rest of the week relative to that hour. 


For example, say there’s a new ice cream shop down the block known for its homemade waffle cones ?. With Location History insights, our systems know that the shop is consistently most crowded on Saturday afternoons at 4 p.m. As a result, popular times information for the rest of the week will be displayed as “Usually as busy as it gets” when it’s approximately as busy as Saturday at 4 p.m.,“Usually not too busy” when it is much less busy, and “Usually a little busy” for somewhere in between. This data can also show how long people tend to spend at the ice cream shop, which is handy if you’re planning a day with multiple activities and want to know how much time to allocate at each place.

Making adjustments in times of COVID

Google Maps’ popular times algorithms have long been able to identify busyness patterns for a place. With social distancing measures established and businesses adjusting hours or even closing temporarily due to COVID-19, our historical data was no longer as reliable in predicting what current conditions would be.  To make our systems more nimble, we began favoring more recent data from the previous four to six weeks to quickly adapt to changing patterns for popular times and live busyness information–with plans to bring a similar approach to other features like wait times soon.


Real-time busyness information: how busy a place is right now

Busyness patterns identified by popular times are useful—but what about when there are outliers? Shelter in place orders made local grocery stores much more busy than usual as people stocked up on supplies. Warm weather can cause crowds of people to flock to a nearby park. And a new promotion or discount can drive more customers to nearby stores and restaurants.


Take the ice cream shop again. Say that, knowing that business is slow on Tuesdays, the shop owners decide to host a three scoop sundae giveaway on a Tuesday to promote their newest flavor—because everyone loves free ice cream! The promotion brings in more than double the amount of customers they typically see on that day and time. Gleaning insights from Location History data in real time, our systems are able to detect this spike in busyness and display it as “Live” data in Google Maps so you can see how busy the shop is right now—even if it varies drastically from its typical busyness levels.


live_busyness

Live busyness information shows you how busy a place is right now

Making sure your data is private, safe and secure

Privacy is a top priority when calculating busyness, and it’s woven into every step of the process. We use an advanced statistical technique known as differential privacy to ensure that busyness data remains anonymous. Differential privacy uses a number of methods, including artificially adding “noise” to our Location History dataset to generate busyness insights without ever identifying any individual person. And if our systems don’t have enough data to provide an accurate, anonymous busyness recommendation, we don’t publish it—which is why there are times when you may not see busyness information for a place at all.


Google Maps is always thinking about ways to solve the problems you face throughout your day, whether they’re big (like getting around safely) or small (like quickly snagging your favorite scoop of ice cream).

Ask a Techspert: How do satellite images work?

When flying, I am firmly a window seat person. (And I can’t wait to start flying again… or at least get out of my apartment.) Not because I’m annoyed by the beverage cart hitting my elbows (though I am), or because I like to blankly stare out at the endless sky (which I do), but because I enjoy looking down at the streets, buildings and skyline of my destination as we land. It’s thrilling to watch cars move, see skyscrapers cast shadows on the street or check out the reflection of the sun in a body of water. For most of human history, it was impossible to even imagine what Earth looked like from above, and only in the past century have we been able to capture it. 

Today, satellite imagery is one of the most popular features on Google Maps. Capturing the world from above is a huge undertaking, matching millions of images to precise locations. But how does satellite imagery actually work? How often are images updated? What are some of the biggest challenges to bringing satellite imagery to more than 1 billion users?

To answer these questions, I reached out to our satellite imagery techspert, Matt Manolides. Matt is Google’s Geo Data Strategist. He’s worked at Google for over 14 years and he gave me an aerial view (pun intended) of how satellite imagery works.

How do we accumulate the images used in Google Maps? Do we actually use satellites? 

The mosaic of satellite and aerial photographs you can see in Google Maps and Google Earth is sourced from many different providers, including state agencies, geological survey organizations and commercial imagery providers. These images are taken on different dates and under different lighting and weather conditions.

In fact, there’s an entire industry around doing aerial surveys. Companies cut holes in the bottom of planes, and cameras take pictures as they fly overhead. In many areas around the world, this is happening constantly. In parts of the world where there isn’t an established aerial survey market, we rely on satellites. With aerial surveys, we get very high-quality images that are sharp enough to create detailed maps. Satellites produce lower-quality imagery, but are still helpful because they provide global coverage. 

Today, you can explore 36 million square miles of high-resolution satellite images in Google Maps and Google Earth, which covers more than 98 percent of the entire population.

When do the images meet the map? 

“Google obtains commercially-available satellite imagery from a range of third parties, and our team stitches the images together to create a seamless map,” Matt tells me. This is a process called photogrammetry and, according to Matt, we’re increasingly able to automate our photogrammetry process using machine learning to help accurately place images and improve resolution. 

For aerial data, the images are delivered on hard disks and we upload them into Google Cloud. For satellite imagery, the data is uploaded directly from our providers to Google Cloud. The imagery is delivered in a raw format, meaning it’s not yet positioned on the ground and is separated into red, blue and green photos, as well as panchromatic images, which includes finer details. We then combine the jumble of images so they all line up and have an accurate placement in the real world, and generally look beautiful.  

Hard drives with satellite imagery in a room

Rooms full of hard drives, each one jam-packed with aerial images.

How often do you update satellite images? 

“We aim to update satellite imagery of the places that are changing the most,” Matt says. For instance, because big cities are always evolving, we try to update our satellite images every year. For medium-sized cities, we try to update images every two years, and it goes up to every three years for smaller cities. Overall our goal is to keep densely populated places refreshed on a regular basis and to keep up with a changing world, so we will refresh areas more frequently when we think there’s lots of building or road construction going on.

Why do we sometimes see mysterious objects on Maps? What are they? 

Matt explains that sometimes the way the images are collected can create optical illusions. One of the most common instances of this are “sunken ships,” which are actually regular, operating ships that might appear underwater due to the way the satellite imagery gets layered together. Other times, sunlight can reflect off something shiny, and it will look like a strange white object that some believe are haunted houses or other such spookiness.

Because the satellite cameras take multiple pictures at the same time, but in different color spectrums, a fast-moving object, like a plane, can look strange, like several identical but differently-colored planes flying over each other. 

"Rainbow" plane image

As for Matt, his favorite part is finding public events that are happening when the images are captured. From hydroplane races to car shows, it’s fascinating to see events in the overhead imagery. 


“When I was a kid growing up in Seattle, I always loved the hydroplane races that would happen each summer. It was a thrill to realize that we captured one from the air back in 2010,” Matt says. “The imagery isn’t visible in Google Maps anymore, but you can still see it using Google Earth Pro’s Historic Imagery feature, which lets you browse our full catalog of imagery.”

“Google obtains commercially-available satellite imagery from a range of third parties, and our team stitches the images together to create a seamless map,” Matt tells me. This is a process called photogrammetry and, according to Matt, we’re increasingly able to automate our photogrammetry process using machine learning to help accurately place images and improve resolution. 

For aerial data, the images are delivered on hard disks and we upload them into Google Cloud. For satellite imagery, the data is uploaded directly from our providers to Google Cloud. The imagery is delivered in a raw format, meaning it’s not yet positioned on the ground and is separated into red, blue and green photos, as well as panchromatic images, which includes finer details. We then combine the jumble of images so they all line up and have an accurate placement in the real world, and generally look beautiful.

How often do you update satellite images? 

“We aim to update satellite imagery of the places that are changing the most,” Matt says. For instance, because big cities are always evolving, we try to update our satellite images every year. For medium-sized cities, we try to update images every two years, and it goes up to every three years for smaller cities. Overall our goal is to keep densely populated places refreshed on a regular basis and to keep up with a changing world, so we will refresh areas more frequently when we think there’s lots of building or road construction going on.

Why do we sometimes see mysterious objects on Maps? What are they? 

Matt explains that sometimes the way the images are collected can create optical illusions. One of the most common instances of this are “sunken ships,” which are actually regular, operating ships that might appear underwater due to the way the satellite imagery gets layered together. Other times, sunlight can reflect off something shiny, and it will look like a strange white object that some believe are haunted houses or other such spookiness.

Because the satellite cameras take multiple pictures at the same time, but in different color spectrums, a fast-moving object, like a plane, can look strange, like several identical but differently-colored planes flying over each other.

As for Matt, his favorite part is finding public events that are happening when the images are captured. From hydroplane races to car shows, it’s fascinating to see events in the overhead imagery. 


“When I was a kid growing up in Seattle, I always loved the hydroplane races that would happen each summer. It was a thrill to realize that we captured one from the air back in 2010,” Matt says. “The imagery isn’t visible in Google Maps anymore, but you can still see it using Google Earth Pro’s Historic Imagery feature, which lets you browse our full catalog of imagery.”

How we’re supporting climate action in European cities

Climate action can have the biggest impact in cities, which are responsible for 70 percent of the world's CO₂ emissions. That’s why we committed to helping more than 500 cities reduce 1 gigaton of carbon emissions annually by 2030 as part of our ambitious plan for climate action. To help reach that goal, ICLEI-Local Governments for Sustainability, with grant support from Google.org, is funding six projects. The projects will use actionable data to test new strategies that can reduce emissions and improve air quality in cities across Europe. 

ICLEI is a global network of more than 1,750 local and regional governments committed to sustainable urban development. Last fall, we granted $4 million in funding to them to establish the ICLEI Action Fund and support nonprofits and academic institutions in Europe and Latin America that are leading data-driven climate action efforts. Here’s a look at the projects that have been funded and what we’ve learned so far. 

Projects selected for funding across Europe

 The Centre for Sustainable Energy plans to establish an open-source, city-wide energy dataset in Birmingham, England. The team will also develop analysis tools that can model decarbonisation options for buildings in the city, overlay and integrate public datasets, and aggregate granular socioeconomic data. 

With these tools, the Centre hopes to develop city-wide interventions and smaller community initiatives that will help the city reach its overall decarbonisation goals. “By combining emissions data for buildings, transport, and energy infrastructure with socioeconomic data, and distributing local community grants, we’ll be able to help residents deliver targeted carbon reduction projects, and support the City Council and Route to Zero Task Force to deliver their city-wide climate emergency ambitions,” said Rachel Coxcoon, Programme Director at the Centre for Sustainable Energy. 

In Hamburg, the CityScienceLab of the HafenCity University will develop a tool incorporating data from Google’s Environmental Insights Explorer (EIE), Hamburg’s urban data platform and other sources. With this tool, they plan to help the city identify areas that can be used as “urban testbeds” for prototyping energy innovations in the Altona, Norg and Bergedorf districts. The prototyping process will help visualise and simulate projects to better understand their projected impact on the city. 

Other Action Fund grantees and their projects include: 

  • Deutsche Umwelthilfe in Berlin: To help the city reach its air quality and carbon-free transport goals, they plan to analyze data about air quality, noise levels and traffic, and use EIE to advocate for data-driven changes to cycling and other transportation infrastructure.
  • Carbon Co-Op in Greater Manchester: Working with local partners, they'll develop multi-sector energy plans for the regions and pilot three citizen-led projects focused on sustainable mobility and energy-efficient buildings. A newly developed urban energy dashboard will help them track impact. 
  • Miljopunkt Amager in Copenhagen: Using Google Air View, traffic data and community-collected data, they’ll test new urban space designs that may improve air quality. 
  • Air Pays de la Loire in Nantes: Using real-time air quality datasets that account for traffic conditions, they will provide citizens and local authorities with tools to make decisions about transportation management and traffic regulation systems.

The latest insights from cities taking data-driven climate action 

Through these projects, we’ve seen how cities are thinking about data-backed sustainability planning and action. So far, we’ve seen trends that can be applied globally.  

First, starting small can lead to a big impact—especially when it comes to data. City-level data can point decision-makers in the right direction, while neighborhood or district data can create the necessary community buy-in for more specific programs or interventions. Second, actionable data can help citizens make informed day-to-day decisions and take action. After all, informed citizens are a critical piece of the puzzle. Last, we saw a huge interest in cities looking to improve air quality through more efficient and low-carbon transportation options. 

To have a meaningful impact on climate change, data-driven approaches must be scaled across the globe. That’s why Google.org provided ICLEI’s Global Secretariat with additional funding to develop case studies so they can share best practices that emerge from the Action Fund with cities around the world that are looking to implement similar data-driven climate interventions. 

 One of our goals at Google is to unlock climate ambitions with data, insights, and innovation to overcome today’s climate crisis. We’re excited to continue supporting leading organizations, such as ICLEI, and cities that share that goal.

3 easy ways to maximize the new Saved tab in Google Maps

The Saved tab in Google Maps lets you save and manage all the places you’re interested in, from must-try restaurants nearby to far-flung places for the bucket list. And it’s a popular feature too. Worldwide, people have saved more than 7 billion places on Google Maps. Even during a time when people may not be travelling as much, we’re seeing people still use the Saved tab as they shift the types of places they’re saving to Google Maps.

What kind of places are people saving? To give you a sense, here’s a selection of the all-time most popular places and recent rising categories:

Today, we’re starting to rollout updates to the Saved tab that will make it even easier for you to find and remember the places that matter most to you. Here are three tips for the new Saved tab:

1. Remember your most recently saved places

When you’ve saved a place a friend or colleague recommended and a few days or weeks have passed, it can be hard to remember what the name of the place was or what list you even saved it to. Now, your recently saved places are organized at the top of the Saved tab so you can quickly find the place you’re looking for.

2. Know when you’re close to a place you’ve saved before

When you have a lot of saved places in your current area, it can be challenging to quickly figure out which is which and where to go. When location permission is enabled, you can see all your nearby saved places sorted by distance and arranged in a carousel for easy browsing to make your next decision a breeze.

3. Remember where you’ve been 

If you’ve chosen to turn on your Location History setting, you can use your Timeline to remember the places you’ve been and routes you’ve taken. You can see how far you’ve biked, walked and ran over the past few days. You can also easily find that amazing hole in the wall restaurant you visited during one of your past vacations, or that cute boutique you popped into a few weeks ago. All of these insights are now organized by time, city, region or country.
