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.

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

A solar farm in the middle of a desert on a day with clear blue skies. 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."

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.

As a major emerging economy, Indonesia's green energy transition is essential to keeping global climate goals alive.

A new CGS report shows Indonesia can achieve 49% GHG reductions by 2035 through high-ambition, economy-wide actions: go.umd.edu/Indonesia...

Infographic with text "Key mitigation strategies for Indonesia to achieve significant emissions reductions by 2035 include" with photos of renewable energy, trees, recycling icon, and emissions. The icons are followed by "Accelerating solar and wind buildout; Bolstering reforestation and rehabilitation targets; Improving municipal solid waste (MSW) management; and Improving circularity to reduce product demand."

At Climate Week in New York, a subtle shift in rhetoric begins to normalize the idea of overshoot, which means surpassing 1.5°C of global warming, with no surefire way of bringing the fever back down.

New National Climate Action Plans Trickle in During Climate Week, But Still Add Up to a Lot of Warming - Inside Climate News

United Nations climate summit discussions suggest that overshooting 1.5 degrees of warming is inevitable.
