This morning I attended UN Secretary General António Guterres’s special address at London Climate Action Week, which clearly linked the global energy and climate crises and offered a near-term solution through low-cost, reliable, and secure clean energy.

I’m excited to be on the ground at London Climate Action Week with @rynacui.bsky.social and @jiehonglou.bsky.social. We are looking forward to connecting with those here and sharing new @ctrglobsust.bsky.social research on the roles of subnational actors in achieving ambitious #ClimateAction.

Nate Hultman @natehultman.bsky.social · 15/04/2026

Robust GHG data are central for making good policy at national, subnational, and international levels. @ctrglobsust.bsky.social's new annual GHG inventory and analysis for the United States provides needed clarity on emissions tracking. Learn more at: ghgi.cgs.umd.edu

We had a good joint side event with @ctrglobsust.bsky.social and partners @nlenvironagency.bsky.social and @newclimate.bsky.social. Great to hear from our expert panel, including @rynacui.bsky.social, on how actors at all levels can support countries in achieving ambitious climate targets.

Nate Hultman @natehultman.bsky.social · 04/11/2025

Last week @americaisallin.com launched a new report, led by @ctrglobsust.bsky.social, that outlines potential pathways for the U.S. to still achieve climate goals aligned with the Paris Agreement.

I’m grateful to have had the chance to speak on how subnational actors can play a major role in achieving climate goals at @worldwildlife.org’s event today. To learn more about how Mexico can achieve its targets, read CGS’s recent report: go.umd.edu/Mexico2035Ambition

It’s important to understand what federal changes are happening to climate policies as we make informed subnational decisions. To support these efforts, @ctrglobsust.bsky.social released an analysis tracking U.S. federal changes that impact the climate sector:

Tomorrow at 9:00am EDT, UN SG António Guterres will deliver an address on the state of global #ClimateAction. This is a critical moment for #ClimatePolicy as countries develop their NDCs and as the need to address climate challenges becomes more urgent.

How does rolling back climate policies like the EPA power plant rules impact US public health? A new CGS report found federal rollbacks can substantially worsen air quality and health, resulting in 22,800 additional deaths by 2035: go.umd.edu/ImpactsofFedClimateRollbacks

Looking forward to building on this week’s discussions at the #SB62 and working toward #COP30. One critical outcome from the #JuneClimateMeetings: demonstrating the critical role subnational groups– in the U.S. and around the world–play in keeping the #ParisAgreement 1.5C target alive.

Nate Hultman @natehultman.bsky.social · 21/06/2025

It’s been an important week at UNFCCC #SB62. We’ve shown US #climateaction is still advancing through leadership from cities, states, businesses & other subnational actors. CGS research shows that #ParisAgreement goals are still within reach. Read: go.umd.edu/stateambition

#Climatescience and #Climatepolicy go hand in hand. At @ctrglobsust.bsky.social, we assess how #ParisAgreement goals can be achievable with subnational, national, and global #climateaction. Evidence-based climate research + informed policymaking can keep 1.5C within reach. #SB62

In the midst of finalizing NDCs, countries’ ambitious goals are within reach. In advance of #SB62, @ctrglobsust.bsky.social released a report exploring pathways for top-emitting countries to reduce GHG emissions, finding a 35% reduction by 2035: go.umd.edu/Global2035Am...

At the #JuneClimateMeetings, key preparation is happening for #COP30. Subnational actors will play a major role in meeting the #ParisAgreement 1.5°C target. Great that state, city, business, and other subnational leaders are represented in #SB62 conversations.

Nate Hultman @natehultman.bsky.social · 17/06/2025

The role of subnational climate action and leadership is critical to meet #ParisAgreement goals. For the U.S., @CtrGlobSust research finds that non-federal actors can make major differences on #climatechange, even when faced with federal inaction. #SB62 go.umd.edu/subnationala...

Successfully reaching shared global climate goals will draw from action across all levels of government. U.S. action continues, and I’ll be at the #JuneClimateMeetings (SB62) in Bonn this week with @americaisallin.com to highlight how such action can keep the U.S. engaged.

Looking forward to this week’s international #JuneClimateMeetings in Bonn. Our mission? Working together to understand and implement national, subnational, and global climate actions to meet #ParisAgreement goals. Let's connect at #SB62.
