Keeping promises on renewables, energy efficiency and methane would avoid nearly 1C of global heating'

"Sticking to three key climate promises on renewables, energy efficiency and methane would avoid nearly 1C of global heating and give the world hope of avoiding climate breakdown, analysis published at the Cop30 climate summit suggests. Governments have already agreed to triple the amount of renewable energy generated by 2030, double global energy efficiency by then, and make substantial cuts to methane emissions."

"Bill Hare, chief executive of Climate Analytics, one of the organisations behind the report, said: If [governments] achieve this by 2035, it would be a gamechanger, quickly slowing the rate of warming in the next decade and lowering global warming this century from 2.6C to about 1.7C. This is close to the target of limiting global heating to 1.5C above preindustrial levels that is at the core of the 2015 Paris climate agreement."

"This would also be essential to avoid further reducing the world's carbon sinks, which absorb carbon dioxide from the atmosphere and balance out the remaining greenhouse gas emissions from fossil fuels. Hare said these targets had already been negotiated, and now just needed to be put into practice: The whole emphasis of this Cop is implementation so I would say the parties need to get on and do it."

Tripling renewable energy by 2030, doubling global energy efficiency and substantially cutting methane emissions would shave about 0.9C from projected 21st-century temperature rise and could avoid nearly 1C of global heating. Implementing these measures across G20 countries alone would cut global greenhouse gas emissions by about 18 billion tonnes in 2035, reducing the rate of warming by roughly a third in the next decade and halving it by 2040. Achieving these targets by 2035 would lower projected century warming from about 2.6C to roughly 1.7C. Stopping deforestation is essential to preserve carbon sinks and balance remaining emissions. Urgent implementation of already-negotiated targets is required.
