In the lead-up to COP30, Greenpeace warns that big emitters are backsliding on their climate commitments by looking to adopt the concept of ‘no additional warming’.
Methane is the fastest way to slow global heating. It traps 80 times more heat than CO₂ over 20 years and is responsible for nearly a third of current warming.
But high-income, high-emitting nations such as New Zealand and Ireland are weakening their methane reduction targets under the misleading concept of “no additional warming” or “temperature neutrality.”
This rollback violates international climate law. It undermines the Paris Agreement’s 1.5°C goal, breaches the principle of “common but differentiated responsibility,” and contradicts the Global Methane Pledge.
The science is unequivocal. Methane levels are now 265% higher than pre-industrial times, and both the IPCC and UNEP confirm that deep cuts by 2030–2040 are essential to avoid temperature overshoot.
Greenpeace is calling on all nations to reject the premise of ‘no additional warming’ and support strong action to cut methane emissions now.
