What’s Your Neighborhood’s Climate Impact?

We usually think about our carbon footprint in terms of individual choices: How often do we fly? Do we eat meat? Have we purchased an electric car?
But household emissions also often depend on factors that we have limited control over, such as the density of our neighborhoods, whether public transportation is available near us or whether electricity in our region comes from coal-burning plants or emissions-free solar plants.
“Consumption is not the individual act we all think it is,” Siobhan Foley, head of sustainable consumption at C40, a network of the world’s biggest cities committed to addressing climate change, told The New York Times. “We treat it like a personal choice, but it’s shaped by all these other factors.”
My colleagues recently published a set of maps that illustrate this idea in stark relief. The maps, based on research from U.C. Berkeley, estimate the emissions of an average household in a neighborhood based on electricity use, car ownership, income levels, consumption patterns and more.
A clear pattern emerges: Across the U.S., households in denser neighborhoods close to city centers tend to be responsible for fewer planet-warming greenhouse gases, on average, than households in the rest of the country. Residents in these areas typically drive less because jobs and stores are nearby and they can more easily walk, bike or take public transit. And they’re more likely to live in smaller homes or apartments that require less energy to heat and cool.
Moving further from city centers, average emissions per household typically increase as homes get bigger and residents tend to drive longer distances. Though what we eat and buy and how often we travel are important factors in determining our carbon footprint, driving and housing are frequently the largest contributors.
“What this shows so clearly is these large-scale patterns,” said Nadja Popovich, a data and graphics reporter on the Climate desk at The Times. In “city after city, place after place, the same thing repeats, with lower-emissions cores and higher-emissions suburbs and exurbs.”

- Covid State of Emergency: The state’s coronavirus emergency declaration, which gave Gov. Gavin Newsom broad powers to slow the spread of the virus, is set to expire on Feb. 28.
- In the Wake of Tragedy: California is reeling after back-to-back mass shootings in Monterey Park and Half Moon Bay.
- Fast-Food Industry: A law creating a council with the authority to set wages and improve the conditions of fast-food workers was halted after business groups submitted enough signatures to place the issue before voters next year.
- Medical Misinformation: A federal judge has temporarily blocked enforcement of a new law allowing regulators to punish doctors for spreading false or misleading information about Covid-19.
Take California’s big cities. The average emissions of a household in central San Francisco are one-third to one-half as much as those in, for example, Los Altos, Mill Valley or Atherton. Similarly, the average emissions of a household in downtown Los Angeles are one-third to one-half as much as those in Calabasas, Rancho Palos Verdes or Malibu.
Households in these suburbs tend to be higher-income, which increases their climate footprint further because people in them can buy more stuff — appliances, cars, furnishings, electronic gadgets — and travel more, all of which comes with related emissions.
But there are also major structural factors: For decades in the United States, a majority of new homes have been built in the suburbs and, increasingly, the exurbs, where climate footprints are larger. As a result, for many people today, it is often easier and cheaper to find a home in a high-emissions community than in a lower-emissions one.
The data suggests that building denser housing in walkable areas with good access to transit is crucial if U.S. cities want to lower their climate footprints. But reducing the climate impact of cities doesn’t mean filling every city and town with huge skyscrapers, experts said.
For example, changes to the layout of suburban communities, such as locating stores, restaurants and community centers closer to homes, can reduce automobile travel and bring down a community’s emissions.
“We really didn’t want it to be something where you’re blamed for your personal footprint,” Nadja told me about the project. “It’s really about these patterns you see across place and space, because decades and decades of policies have shaped our cities to look the way we do.”

582,462 and counting: This year, reporters and photographers from The New York Times shadowed the Point-in-Time Count — the annual tally of those who live outside or in homeless shelters, which takes place through the last 10 days of January — to examine homelessness in vastly different places in America, including Los Angeles.

With Valentine’s Day coming up, Times editors and reporters shared their favorite romantic restaurants. Jodi Kantor, an investigative reporter, said she fell in love with her husband 25 years ago over a menu:
“He took me to Chez Panisse, in Berkeley, Calif. The dessert menus arrived. A worn soundtrack started playing in my head: enough, no, don’t, bad.
‘I think we should get three,’ he said.”
