Ambition is going to be a key question going into #COP30 and beyond — notably the need for countries who are currently below the needed levels of ambition to revisit targets.

Good to see a core group of countries with good #NDCs including Brazil, Australia, UK, Japan, and indications of a good range from the EU.

It was an honor to attend the #UNGA Climate Summit and hear from UN Secy. Gen. António Guterres and @lulaoficialbluesky.bsky.social about the importance of #ClimateAction as countries finalize their #NDCs.

Excited to be in New York for #ClimateWeekNYC. It has been great engaging with important #ClimateAction conversations and bringing @ctrglobsust.bsky.social insights to show NDC pathways towards meeting #ParisAgreement goals. Looking forward to the rest of the week.

How can Maryland support renewable development? @ctrglobsust.bsky.social's analyses pointed to the importance of bridging the information gap to connect communities with available resources.

While climate policies are being rolled back at the federal level, states and other subnational players can still make a difference.

We’re in the home stretch of the #NDC 3.0 cycle, and South Korea has the opportunity to achieve ambitious #ClimateGoals according to a @ctrglobsust.bsky.social assessment. Read more: go.umd.edu/SouthKorea2035Ambition

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:

What recent federal actions have steered the US back to fossil fuels?

- Easing federal fossil fuel regulations
- Creating hurdles for siting and permitting of wind and solar energy projects
- Pausing renewable project leasing

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.

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.

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.
