In this Q&A, @weipengclimate.bsky.social and group members @carlacamposm.bsky.social and Jinyu Shiwang explain their work to model the air pollution and health impacts of the energy transition. “We cannot simply measure success in terms of tons of CO2 avoided,” said Campos Morales. bit.ly/45gooUW

In light of lagging progress toward climate targets, Andlinger Center researcher Chris Greig and co-author Sam Uden proposed a different strategy for navigating the risks of the energy transition in a Nature Communications perspective. bit.ly/3B1cPpg

Perspective: Is it time to consider temporary ‘off-ramps’ for our climate targets?

In a recent perspective, Chris Greig and Sam Uden call for a reconsideration of how to navigate the risks of transforming energy systems in only a handful of decades.

The new NYT piece on China's supply chain strategy reveals how Beijing is rewriting the rules of economic warfare. Trump's claim that "China pays for tariffs" fundamentally misunderstands modern economic power. Here's why: 1/ www.nytimes.com/2024/11/27/b...

China Has a New Playbook to Counter Trump: ‘Supply Chain Warfare’

A series of swipes at American companies show how China could take the initiative in a new trade war, using its economic dominance to exact pain.

Excited that @andlingercenter.bsky.social 's first post on this site is about our work! Thanks for the shoutout 😀 Check out our paper on how to incorporate pollution, health and equity concerns into Pennsylvania's coal retirement strategies👇 pubs.acs.org/doi/full/10....

Designing Retirement Strategies for Coal-Fired Power Plants To Mitigate Air Pollution and Health Impacts

Retiring coal power plants can reduce air pollution and health damages. However, the spatial distribution of those impacts remains unclear due to complex power system operations and pollution chemistry and transport. Focusing on coal retirements in Pennsylvania (PA), we analyze six counterfactual scenarios for 2019 that differ in retirement targets (e.g., reducing 50% of coal-based installed capacity vs generation) and priorities (e.g., closing plants with higher cost, closer to Environmental Justice Areas, or with higher CO2 emissions). Using a power system model of the PJM Interconnection, we find that coal retirements in PA shift power generation across PA and Rest of PJM, leading to scenario-varying changes in the plant-level release of air pollutants. Considering pollution transport and the size of the exposed population, these emissions changes, in turn, give rise to a reduction of 6–136 PM2.5-attributable deaths in PJM across the six scenarios, with most reductions occurring in PA. Among our designed scenarios, those that reduce more coal power generation yield greater aggregate health benefits due to air quality improvements in PA and adjacent downwind regions. In addition, comparing across the six scenarios evaluated in this study, vulnerable populations─in both PA and Rest of PJM─benefit most in scenarios that prioritize plant closures near Environmental Justice Areas in PA. These results demonstrate the importance of considering cross-regional linkages and sociodemographics in designing equitable retirement strategies.

Researchers led by @weipengclimate.bsky.social have demonstrated that traditional strategies for retiring coal plants based on minimizing costs could be leaving other #climate and equity benefits on the table. 🧪 acee.princeton.edu/acee-news/re...
