Excited to see our new paper which analyzes the politics of American climate inaction and polycentric rebellion out in Energy Research & Social Science (ERSS). We analyzed 40+ years of the body of work on U.S. climate and energy policy and its contestation.

Elmore’s book is great — and it’s always kind of amused me (and says a lot about LCA as decision *support*, not decision *making*) that Coke more or less invented LCA to evaluate glass vs plastic, found glass was environmentally preferable, then went with plastic anyway

Climate Policy Reduces Racial Disparities in Air Pollution from Transportation and Power Generation Energy system optimization models facilitate analyses on a national or regional scale. However, understanding the impacts of climate policy on specific populations requires a much higher spatial resolution. Here, we link an energy system optimization model to an integrated assessment model via an emission downscaling algorithm, translating air pollution emissions from nine U.S. regions to U.S. counties. We simulate the impacts of six distinct policy scenarios, including a current policy and a 2050 net-zero target, on NOx, SO2, and PM2.5 emissions from on-road transportation and electricity generation. We compare different policies based on their ability to reduce emission exposure and exposure disparity across racial groups, allowing decision-makers to assess the air pollution impacts of various policy instruments more holistically. Modeled policies include a clean electricity standard, an on-road ICE vehicle ban, a carbon tax, and a scenario that reaches net-zero GHG emissions by 2050. While exposure and disparities decrease in all scenarios, our results reveal persistent disparities until at least 2040, particularly for Black non-Hispanic Americans. Our estimates of avoided deaths due to air pollution emphasize the importance of policy timing, showing that thousands of lives can be saved by taking action in the near-term.

Using a retirement model of 3,765 coal power units across China, the study reveals that for the majority of these workers, green jobs are not just around the corner—most would have to travel substantial distances, averaging between 178 and 242 kilometers, to reach available renewable energy jobs.

Decarbonization is essential to achieving climate goals, but myopic decarb policies that ignore co-pollutants may leave Black and high-poverty communities up to 26–34% higher PM2.5 exposure than national averages over the energy transition. #EnergySky #EnergyJustice www.nature.com/articles/s41...

Folks, I am really appreciative of people who have followed me and added me to their starter packs.

I post about climate science, energy system transition, and related issues.

I try to restrain myself to information and questions, and try to avoid unseemly opining in public.

I love all the guesses but the correct answer is that this is an image of cat litter on a basement floor illuminated by the Dyson V15 Detect, the best vacuum I’ve ever owned

How will China impact the future of climate change? You might be surprised As a new Trump administration signals a retreat on climate action, China is stepping up. China is the biggest producer of climate technologies like electric vehicles and solar panels.

While the U.S. is signally a possible retreat on federal climate action, in China it's a different story.

"The U.S. does not want to get into a table tennis game with China because that game the U.S. cannot win," says Li Shuo.

Geospatial Life Cycle Analysis of Greenhouse Gas Emissions from US Liquefied Natural Gas Supply Chains Growth in US liquefied natural gas (LNG) exports has increased concerns about the climate impacts of methane leakage along LNG supply chains. Current life cycle analysis (LCA) models of US LNG supply chains are based on emission estimates in national inventories that have been demonstrated to significantly underestimate emissions. In addition, recent top–down measurements of methane emissions exhibit significant subnational spatial and temporal variations across oil and gas (O&G) basins. In this study, we develop a geospatial, measurement-informed LCA model that incorporates recent top–down methane measurements to examine regional differences in greenhouse gas (GHG) emission intensity of US LNG supply chains for delivery to Europe and Asia. For every megajoule of LNG shipped from the US, the energy-allocated GHG emission intensity of the Permian-UK LNG supply chain is 42% higher compared to the Marcellus-UK LNG supply chain. Differences in basin-specific, measurement-informed inventories are a key driver of disparities in supply chain LNG emission intensity. Developing measurement-informed, supply chain-specific lifecycle GHG emission assessments is critical to enabling a global market for differentiated natural gas.

🔴New Paper!

We have developed the first, geospatial, measurement informed LCA of US LNG supply chains! No longer are we limited to treating US as a blob & instead look at specific supply chains!

I hope this provides some clarity to a lot of sloppy #LNG impact analyzes recently. #climate #EnergySky

Alt text: Screenshot of CGS’s report “Table 2.1. Total GHG Emissions Reductions by 2035 for the G20 Countries and Globally Under the High” which shows for 17 major emitting regions as well as for World what a high ambition 2035 NDC emission target would be, in total GHG incl. and excl. LULUCF compared to the countries respective base year (or future assumed peaking year), as well as in GHG excl LULUCF compared to 2023 (as this is the most comparable metric, though country specificities mean that even in that metric, differentiation is of course to be expected).

As more 2035 NDCs are being released, it comes in handy that we at Center for Global Sustainability have just published a report on what High Ambition 2035 targets could be for 17 major emitting countries, as well as their combined global emissions and temperature impact. tinyurl.com/56pyu3sd 1/6
