CGS’s new analysis of US #ClimateAction in @ddpinitiative.bsky.social's 2025 report identifies how the US has moved toward achieving climate goals, although political swings have limited progress. With these limitations, the role of subnational actors will be critical: ddpinitiative.org/dd...

Stay tuned for updates through #COP30 and beyond, as the website will continue to track and evaluate 2035 NDCs, update country and global assessments, and expand to new countries.

Text reads, "'Our country assessments take into account the unique factors of each of the 12 countries we've analyzed so far. Our goal is to provide tailored, actionable recommendations. The Country Climate Ambition Project will help countries and stakeholders chart a credible course towards enhanced ambition for a climate-resilient future.' - Dr. Ryna Cui, PhD".

Ongoing #NDC 3.0 submissions are a key opportunity for countries to reevaluate and set more ambitious climate targets.

A journal article in Energy Economics titled, "Unlocking synergy: The coeveolution mechanism of enterprises' green innovation decisions under China's energy-saving regulations".

Energy-saving regulations struggle to simultaneously enhance efficiency and curb consumption in many developing countries.
To address this, a new study in Energy Economics explores optimal regulations to foster green innovation while reaching energy goals: https://doi.org/10.1016/j.eneco.2025.108920

The report draws on analyses from DDP experts across 21 countries, representing a diversity of geographies, sizes, and levels of development. The analysis in the U.S. chapter was led by the @ctrglobsust.bsky.social

A Review of Federal Climate Policy Rollbacks in the United States: Trends, Sectoral Changes, and Implications for Policymakers | Center for Global Sustainability

What steps has the current administration taken to change the trajectory of energy and environmental policy in the US?
@ctrglobsust.bsky.social's recent analysis examines all the recent federal climate policy rollbacks and their implications for US climate action: go.umd.edu/FederalRollbacksReview

New Report Marks a Decade of Progress, Challenges on Global Decarbonization - Inside Climate News Extreme shifts in federal climate policy will make it hard for the U.S. to reach the Paris Agreement targets, but action by states, cities and businesses could still deliver significant emissions cuts...

On @ddpinitiative.bsky.social's new report, @aliciaszhao.bsky.social told ICN recent US federal climate policy rollbacks have created uncertainty around delivery of US commitments under the Paris Agreement, but subnational players can drive emissions reductions: insideclimatenews.org/news/0610202...

Stay tuned for updates and additional country and global assessments through #COP30 and beyond as we track 2035 NDCs and add new countries.

Text in a box on the left-hand side reads, "Countries need to pursue ambitious NDCs to curb emissions growth and meet the goals of the Paris Agreement. Explore CGS's new website to learn how countries can ramp up ambition in their 2035 NDCs."

How can the world’s major emitting countries ramp up ambition in their 2035 NDCs?

To aid this effort, the @ctrglobsust.bsky.social launched a new website providing in-depth analyses of plausible, high-ambition pathways for 2035: www.country-ambition.cgs.umd.edu

The CGS-led U.S. chapter analyzes the past decade of climate policy and sectoral transitions, finding uneven progress shaped by shifting federal administrations. However, there's been key progress in retiring coal, deploying clean energy, and growing non-federal action.
