⚖️ The advisory opinion from the @CIJ_ICJ is a milestone for climate justice affirming states’ legal duties to act on #climatechange. While not binding, it carries real weight. As momentum builds, @UNFCCC remains key to turning principles into progress for people & planet.

The global shift to renewables is increasingly inevitable, but its massive human and economic benefits are not yet being shared across all countries and regions. To deliver on the global agreement at COP28 to triple renewables by 2030, we need to move much further and faster.

As we close the #JuneClimateMeetings, it is clear we need to go further, faster, and fairer. Progress has been made on some areas, but others struggled. We must find ways to get to the hard decisions sooner. All eyes will be on #COP30. 👉bit.ly/4erzo5S

Youth voices and solutions are more important than ever. 💪🌎 Watch COP30 Youth Climate Champion Marcele Oliveira (@pycccop30) and UN Climate Change Executive Secretary Simon Stiell discuss the power of collective climate action. #JuneClimateMeetings | #COP30 #mutirão

Climate reporting shapes stronger policies & helps identify funding needs and investment opportunities. At 1st Multilateral Consideration of Progress, countries shared lessons, results & challenges from implementing their climate commitments, for people, prosperity and planet.

The 10 year anniversary of the Paris Agreement is a moment both to reflect on progress so far & the work ahead. Over the next decade, we must accelerate & implement, delivering real economy impacts & real-life benefits for 8 billion people. We must go further, faster, fairer.

My message to young people: never underestimate your power. Be loud and proud — in your communities, on social media, in schools, and on the streets. Fantastic to meet the #COP30 Youth Climate Champion Marcele Oliveira (@pycccop30) again at the #JuneClimateMeetings.

Solving the climate crisis needs everyone — with faster action and large-scale delivery. Bold national climate plans + implementation on the ground are key. Great to talk with the COP29 & COP30 Climate High-Level Champions on connecting ambition to action.

Climate multilateralism has delivered clear progress at each recent COP. If we want #COP30 in Brazil to take us another global step forward, we need the next eight days to deliver concrete progress at the UN #JuneClimateMeetings. Let’s get to work. 👉bit.ly/3ZAvKAB

Ahead of the #JuneClimateMeetings SB62, two things are clear: 👉complex & vital work lies ahead on  the road to COP30 in Brazil. 👉 Parties must make concrete progress over next ten days Let's get to work – for people, prosperity and planet.

The #JuneClimateMeetings (SB62) kick off 16 June — laying the groundwork for ambitious outcomes at #COP30. The @UNFCCC secretariat is here to help countries & others drive progress on climate action, for people, prosperity & planet. 👉Our recent work: bit.ly/43YUPX4

Climate finance is about the ability to deliver climate actions - to protect people, prosperity and planet. @theGEF plays a crucial role in this effort - turning ambition into action by directing funds where they are needed most, and can have most impact. #GEFcouncil69

Mexico’s new climate plan can supercharge the country’s growth: more jobs, innovation, stronger communities & healthier citizens — while cutting the pollution destroying our planet. As a G20 country, Mexico can position itself as a leader in climate action on the road to #COP30.

The COP30 President-Designate’s message is more urgent than ever: We need to reinforce multilateralism & climate negotiations under the @UNFCCC, find solutions that benefit people’s lives & go full steam ahead to implement the goals of the Paris Agreement. bit.ly/4jha4Aa

I am deeply saddened by the passing of Sebastião Salgado. A tireless champion of nature and human dignity, he used his art to advocate for the planet’s most vulnerable people and ecosystems. His legacy will continue to inspire action and advocacy for our planet & its people.

Nepal’s new & whole-of-government national climate plan (NDC) is an encouraging sign that more & more countries are embracing the vast opportunities that ambitious climate action holds: For growth, for jobs, for energy security, for better health & for a safer, more stable world.

#ClimateWeek2025 marks a new chapter. We need to fast-track the climate action journey from ambition to implementation, to make faster progress in the real economy - the heartbeat of climate action. Let's show how climate action can deliver more for people, prosperity & planet.

Moldova just submitted a strong new #NDC: ✅ 75% net GHG cuts by 2035 (vs. 1990) ✅ Legally binding 2050 climate neutrality goal ✅ Informed by the Global Stocktake Let's keep the momentum going.

The clean energy transition can propel economies & societies forward — creating more jobs, improving health, and opening up new opportunities for communities and businesses.   #Kenya’s new national climate plan (NDC) recognizes this immense potential. 👉bit.ly/4gSU8Eb

In times of global uncertainty, one thing is crystal clear: International cooperation has never been more vital. To tackle climate change, loss of biodiversity & desertification, for a livable world. We will only succeed if we rise to this challenge together. #ChangeNow
