Die EU hat einiges geschafft im Klimaschutz, darf jetzt aber für Klimaneutralität 2050 nicht schwächeln.
- Kurs halten und ambitioniertes 2040er Ziel verabschieden
- Unabhängig von fossilen Importen machen (400 Mrd 2024)
- Auf sozialen Ausgleich achten

Würdest du in ein Flugzeug steigen, das mit 37%er Wahrscheinlichkeit abstürzt? Du würdest das Urteil der Ingenieur*innen nicht in Frage stellen.

Mit 37%er Wahrscheinlichkeit ist es 2100 global 3°C wärmer. Existenzbedrohend. Würde unsere Gesellschaft nicht aushalten

#China's new #climate target is unlikely to drive down emissions: the country will already achieve it under its current policies.
It's a net target that includes land use & forestry; an absolute target wld be more transparent
It's a shift from emissions & energy intensity to absolute emissions

While state-level initiatives continue, the federal shift represents a significant setback.

With climate impacts intensifying across the US, these actions move the country further away from a 1.5°C pathway and represent “the most aggressive, comprehensive and consequential climate policy rollback” the CAT has ever analysed, according to @niklashoehne.bsky.social.

Key developments:
➡️ Federal targets annulled
➡️ Expanded oil & gas production on federal lands & waters
➡️ Slowed deployment of wind, solar & EVs
➡️ Rollback of emissions regulations for power plants & vehicles

🚨 Climate Action Tracker downgrades #US to "Critically insufficient"

“It is alarming how systematically the Trump Administration has rolled back measures to reduce emissions, while aggressively expanding support for fossil fuels”, says Finn Hossfeld.

Shocking. The rollback of climate policies of Trump Administration is most systematic, comprehensive, fast, impactful we ever analysed.

Good part: still many forces in USA work towards a zero GHG emissions, can be seen especially here at #ClimateWeekNYC, starting today.

COUNTRY ANALYSIS: We have downgraded the #US climate action to "Critically insufficient" - it's the most aggressive, comprehensive and consequential climate policy rollback the CAT has ever analysed.

While the US no longer has any official climate targets since its exit from the #ParisAgreement, there remains a coalition of states who are still working toward meeting the targets submitted by the US ahead of last year's election. However, the government is trying to head off that effort too.

US emissions are projected to be ~600MtCO2e-800MtCO2e higher in 2030 under the current administration’s policies and actions compared to its predecessor.
We project US emissions to drop to 19-30% in 2030 below 2005 level (excl LULUCF) - from 29-39% previously.

The Trump Administration is pursuing an agenda to systematically repeal federal climate targets, policies, funding for mitigation, blocking progressive actors, while encouraging the production and consumption of fossil fuels at home and abroad.

Europa sendet fatales Signal mit Folgen weit über EU hinaus. Bleibt Europa blank, werden andere kaum Führung im Klimaschutz übernehmen. Lässt EU 2040er Klimaziel schleifen, gäbe man das Ziel auf, Klimaneutralität bis 2050 zu erreichen – und damit auch Paris.

Verschieben hat Konsequenzen weit über die EU hinaus: es könnte Prozess neuer Ziele im Pariser Abkommen durcheinander bringen und Erfolg des nächsten Klimagipfels gefährden. Der Prozess ist durch Trump ins Stocken geraten. Es braucht Vorreiter - also die EU - um ihn wieder ans Laufen zu bringen.

Das Argument, Verschleppen von Klimaschutz sei gut für Wirtschaft, ist oft widerlegt. Schlecht für die Wirtschaft ist Stop-and-go Politik. Es bestraft, die auf Innovation gesetzt haben, und die belohnen, die sich zurückgelehnt haben, um ihr fossiles Geschäftsmodell weiter betreiben zu können.

The delay of decision on 2040 EU climate target has consequences far beyond EU: on international process. EU could have generated new momentum for other countries' climate targets at UNSG summit 24 Sept. Missed opportunity. Hope delay leads to a strong target.

Das Vertagen der Entscheidung über 2040er EU Klimaziel hat Folgen weit über die EU hinaus: Es bringt den internationalen Prozess durcheinander. Die EU hätte beim UNSG Gipfel 24. Sept neues Momentum für Klimaziele anderer Länder entfalten können. Das wird jetzt verpasst.
