The Brief

California is again updating the system it uses to decide which polluted communities get cleanup funding. The tool, CalEnviroScreen, has already steered billions of dollars to the state’s most burdened neighborhoods, but critics say it still overlooks some of them.

The update is reigniting a long-smoldering debate: officials promise they're listening to communities more than ever, while advocates say the state's data gaps leave some areas invisible to the system designed to help them.

What’s new

Officials at the Office of Environmental Health Hazard Assessment, the state agency managing the tool, said they worked with eight community organizations to design this fifth update – including the Environmental Health Coalition, UNIDOS Network and Comite Civico del Valle. The update adds two indicators: diabetes prevalence, because people with diabetes are more vulnerable to air pollution; and small air toxic sites, to track additional risks from sources like urban oil wells and dry cleaners.

EnviroScreen also incorporates data improvements among some of the 21 other indicators it uses, such as adding children’s blood lead levels to a risk assessment for lead exposure from housing. The state will hold virtual and in-person public meetings this month to gather feedback; officials said they expect to publish a final version in the summer.

“We listen to stakeholders, community groups, academics, government agencies to understand any new layers that might be needed to better characterize both the pollution burden and the population vulnerability,” said Álvaro Alvarado, the environmental agency’s supervising toxicologist. “It's a constant work in progress.”

State law requires at least 25% of California's cap-and-invest funds — money raised through greenhouse gas auctions — go to the most disadvantaged communities. Since 2014, the state has used CalEnviroScreen to define them, including the top 25% of census tracts in that definition.

Laura August, the agency’s environmental program manager, said the update does not dramatically shift the census tracts identified as among the most polluted. She said the Bay Area and Central Valley decreased in the ranking slightly. About 80% of communities designated as disadvantaged remain unchanged in the new update, she said.

How the tool works and what it’s missing

Disadvantaged communities have received at least $5.8 billion in cap-and-invest funds since 2015.

Environmental advocates said that although the tool is essential and provides important resources, it still leaves out important information. Some critics want to see additional indicators, such as tree canopy coverage and wildfire smoke data.

“It would need to have the kind of ground-truthing work … which is to literally walk the neighborhood and count and calculate all the different polluting sources (and stressors) like heat islands and lack of tree cover and water stress,” said Rebecca Overmyer-Velazquez, a coordinator for the Clean Air Coalition of North Whittier and Avocado Heights.

State environmental officials said they plan to incorporate climate data and data about pollution magnets, like warehouses, in future versions of the tool.

Questions about the methodology

Beyond what data to include, researchers have also questioned whether the tool's design itself creates blind spots.

In 2024, researchers with Johns Hopkins University found the previous version of the tool, CalEnviroScreen 4.0, was subjective enough that certain communities could be losing out on billions of dollars.

“If you're the model developer, even if you don't feel that you have any personal biases or you're not thinking about it, all those choices that you make when you make the model, you are implicitly deciding who gets funding and who doesn't,” said Benjamin Huynh, an assistant professor at Johns Hopkins Bloomberg School of Public Health.

For example, the current version of CalEnviroScreen includes data about emergency room visits for asthma as an indicator of how sensitive to air pollution people in a particular area are. But some people, including immigrants, are less likely to visit an emergency room than others – or even visit doctors in the first place, to get diagnosed.

August said the agency took researchers’ criticism seriously. Late last year, she and other state scientists defended the tool in a published report, finding that the state’s methods "prioritize generalizability, dissemination, and utilization without sacrificing accuracy."

Advocates want real change 

But even with improvements to the data, advocates said the bigger problem is how the tool gets used — or not used.

CalEnviroScreen was a product, in part, of advocacy from environmental justice leaders in the 1990s. But advocates said they aren’t sure whether the programs funded by the money are actually leading to pollution reduction, and agencies aren’t using the tool aggressively enough in their own policies.

Bradley Angel, director of the environmental group Greenaction for Health and Environmental Justice, faulted the state for not using the tool to deny waste permits to polluters.

“It's great that CalEnviroScreen exists … but when communities and environmental justice groups were advocating for what became CalEnviroScreen, they weren't looking at dollar signs. They were looking to protect our health,” Angel said.

State agencies do use the tool in some policy decisions. The Air Resources Board used EnviroScreen to determine which communities would be a part of its Community Air Protection program, which aims to reduce air pollution.

Under a draft regulation, officials with the Department of Toxic Substances Control said it will use CalEnviroScreen as a proxy for cumulative impacts in permitting decisions. But environmental advocates have called the regulation flawed because those impacts cannot prevent the department from issuing a hazardous waste permit.

“Unfortunately, but not surprisingly, (the department) pays lip service to CalEnviroScreen’s own information,” Angel said.

Looking to other states

At least one other state proves that more aggressive responses to environmental justice indicators are possible, advocates said.

New Jersey has developed a data tool, influenced by CalEnviroScreen. Two years ago, New Jersey started requiring polluting facilities to use its tool to analyze cumulative impacts of different pollution sources in a community. State regulators must deny permits to facilities that can’t avoid harm to overburdened communities.

“The tool is just a tool,” said Caroline Farrell, director of the Environmental Law and Justice Clinic at Golden Gate University. “You've got to be able to figure out how you want to utilize it in a way that actually changes things on the ground for communities.”

Big Bear’s famous bald eagles — Jackie and Shadow — appear to be welcoming a new chick into the world.

The first pip, or crack, was spotted in one of the feathered duo’s two eggs around 10 a.m. Friday, according to Friends of Big Bear Valley, the nonprofit that runs a popular YouTube livestream of the nest overlooking Big Bear Lake.

More than 26,000 people were watching the livestream shortly after the organization confirmed a pip had been spotted, which signals that an eaglet is starting to poke its way out of the egg shell.

“Yesterday afternoon, evening and throughout the night we heard little chirps coming from the chick,” Friends of Big Bear Valley wrote on Facebook to more than a million followers. “This indicates that the chick was able to break the internal membrane and took its first breath of air.”

As of Friday, the first egg is around 38 days old and the second egg is about 35 days old. Jackie and Shadow's usual incubation timeline is around 38 to 40 days, according to the nonprofit.

There’s still time for the second egg to show signs of hatching, and a pip could be confirmed in the coming days.

What we know

Jenny Voisard, the organization’s media manager, told LAist earlier this week that hatching is an arduous process for chicks that takes some time.

For example, last season, the first chick hatched more than a day after the initial pip was confirmed, according to Friends of Big Bear Valley records. The second chick hatched about a day after pipping as well, and the third chick worked its way out into the world about two days after the first crack was confirmed.

The chicks may look like little blobs of gray fluff at first, but they grow quickly, as fans saw with Jackie and Shadow’s eaglets last year. One of last season’s trio of chicks, believed to be the eldest and most dominant sibling, died during a winter storm within weeks of hatching.

In March 2025, Jackie and Shadow welcomed two eaglet chicks with one remaining egg in their nest.

Viewers watched as the surviving eaglets, Sunny and Gizmo, grew from a few ounces to several pounds in a matter of months before fledging, or taking their first flight away from the nest, last June.

But any chicks arriving this season will have to learn how to feed before they can fly.

The initial meals may be a bit awkward while the chicks learn to sit up straight. Jackie and Shadow could start feeding the chicks the same day they hatch, typically tearing off pieces of fish or raw meat and holding it up to their beaks.

Bald eagles don’t regurgitate food for their young, unlike other birds. But the feathered parents do pass along a "substantial amount of saliva” full of electrolytes and antibodies to their chicks during feedings, according to the nonprofit.

Voisard said new life coming to the nest is a reminder “why it’s so important to conserve their lands.”

Big Bear fundraiser

Friends of Big Bear Valley is trying to raise $10 million by the end of July to purchase land pegged for a planned housing project that some say would harm rare plants and wildlife in the area, including bald eagles.

California Attorney General Rob Bonta provided guidance this week to childcare providers on new legal requirements to protect children and their families from immigration enforcement activities.

Under a new law that went into effect this year, childcare providers are not allowed to collect information about a child's or family member’s immigration status, unless necessary under state or federal law. Bonta’s office says there currently is no such requirement, though that could change with federal programs like Head Start.

“Childcare and preschool facilities should be safe and secure spaces so children can grow, learn and simply be children,” Bonta said in a statement.

His office says daycare centers also should not keep information about a formerly enrolled child longer than is required by state law.

The new law also requires facilities to inform the attorney general’s office and the state’s licensing agency if they get any requests for information from law enforcement related to immigration enforcement.

Facilities also must ask families to regularly update a child’s emergency contact information to make sure someone can be reached in case a parent is detained by federal immigration officials.
