PSE&G will use technology from EDF and partners to find and reduce methane emissions from gas lines.

Methane leak data is available for utilities, researchers and academic bodies.

EDF and Kaiser Permanente combined block-by-block traffic-related air pollution data with electronic health records to show how location impacts health.

Blockchain, data analytics, automation, dematerialization, and more are driving how companies balance their business and environmental goals.

With incentives, technology developers can work with public health researchers to unlock solutions allowing us to track exposure to hazardous chemicals.

A new study from the Western Regional Air Partnership finds methane emissions from New Mexico’s oil and gas facilities are higher than previous estimates.

A report grading states on their mandatory and voluntary residential disclosure policies for lead pipes.

Water heaters may function as “lead traps,” but more investigation is needed. Best to avoid using hot water for cooking or drinking.

With the right standards, Pennsylvania could reduce pollution by up to 60%

EDF estimated total annual methane emissions from all oil and gas wells in Pennsylvania.

Scientific research paints a comprehensive picture of oil and gas emissions.

EDF and Con Edison collaborated to more effectively reduce methane escaping from the system.

New tech identifies problem areas faster, cheaper than before, reducing waste and emissions

A report based on recent scientific breakthroughs in methane quantification finds that emissions of methane are drastically higher than state reports.

EDF scientific analysis offers insights into New Mexico's methane waste problem

Our readings indicated an average of about one leak for every two miles we drove within the study areas.

Tracker of states committed to fully replacing all of their lead service lines.

By not addressing climate change, the Trump administration is treating hurricane recovery like a doctor who treats the symptoms of a patient – while ignoring a dangerous, underlying disease.

Amid a sustained slump in sales for natural gas vehicles, a new study highlights significant challenges for these vehicles to deliver on their modest potential of climate emission reductions; the ultimate climate impact of these vehicles rests on the actions and practices of the upstream supply chain, or well-to-pump suppliers.

Climate change is contributing to hotter heat waves and more damaging storms. When it comes to air travel, these events can lead to delays, cancellations and bumpier skies.

We have identified communities that have set a goal of fully replacing all lead service lines in their jurisdictions. Here's a look at those communities.

Updated USGS maps show decreased rate of Louisiana land loss. Conservation groups including EDF say urgent action still needed to slow down continued land loss and build new land.

In children, even very low blood lead levels can cause behavioral problems and lower IQ.

In this published study, we demonstrate a measurement approach to reveal urban air pollution patterns at 4-5 orders of magnitude greater spatial precision than possible with current central-site ambient monitoring. If validated elsewhere, this readily scalable measurement approach could address major air quality data gaps worldwide.
