Besides the imperative to phase out oil and gas, our work also shows the importance of data integrity and transparency, and regulations on air pollution and environmental justice to protect the public.

The health burden and racial-ethnic disparities of air pollution from the major oil and gas lifecycle stages in the United States
Largest total population health burden is from O&G end-use, but greatest relative disparities are linked to downstream activities.

...Much of this disparity stems from a legacy of #redlining zoning practices that relegated certain populations to live near pollution hotspots. Permitting of oil refineries and petrochemical facilities is another factor.

91,000 Premature Deaths Each Year Linked to US Air Pollution
Air pollution from oil and gas production and use in the U.S. has an enormous health toll. A new study tallies the cost.

#3 The greatest health burden from all O&G stages are found in the most populated states (CA, TX, NY, PA, NJ). End-use activities dominate all incidences, except for cancer risk in specific states with large O&G extraction basins, such as CO, TX, and ND.

Our new @science.org study led by @kohrathefog.bsky.social is the first to comprehensively quantify the health impacts of and inequities in outdoor air pollution exposure across all stages of the US oil and gas lifecycle: extraction ➡️ transport/storage ➡️ refining/processing ➡️ end-use. 🧵
