🚨 OUT NOW! 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. 🧵

The 2025 edition of the #ProductionGapReport by @sei.org et al. is out now! As Christiana Figueres eloquently put in the foreword: The clarity from the #ICJ Advisory Opinion that fossil fuel production and exploration could violate international law must translate into action as we head for #COP30.

Nations’ plans to ramp up coal, gas and oil extraction ‘will put climate goals beyond reach’

New data shows governments now planning more fossil fuel production in coming decades than they were in 2023 Governments around the world are ramping up coal, gas and oil extraction which will put climate goals beyond reach, new data has shown. Far from reducing reliance on fossil fuels, nations are planning higher levels of fossil fuel production for the coming decades than they did in 2023, the last time comparable data was compiled.

To make up for lost ground and steer the world toward a Paris Agreement-aligned track, we must rapidly and steeply wind down #FossilFuel production & use to the lowest levels possible.

A quote next to her photo reads, "Let this report be both a warning and a guide. What we need now is courage and solidarity to move forward at great speed with the just transition."

🚨 BREAKING: Governments plan to produce over 2x the amount of fossil fuels in 2030 than would be consistent with limiting warming to 1.5°C, says the new #ProductionGap Report.

When oil and gas infrastructure leaks the potent greenhouse gas methane, it also releases toxic air contaminants that have escaped notice, until now.

Thank you! And thank you for flagging this important RMI project! To expand this kind of health impacts assessment beyond the US we would also need detailed air pollutant emissions beyond GHGs alone, like those compiled in the US EPA's 2017 National Emissions Inventory for the oil and gas sector.

3) Why striving for "net-zero" emissions shouldn't be the only be-all and end-all, and how this can lead to perverse greenwashing branding of "clean" fossil fuels (which are a complete fallacy). www.sei.org/perspectives...

It's time to move beyond "carbon tunnel vision"

As we decarbonize our energy system, we must address not only carbon emissions, but also the harmful public health and environmental impacts of oil and gas extraction.

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.

Ploy Achakulwisut, PhD @ploya.bsky.social · Aug 24

...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.

#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.
