Analysts estimate that new national pledges to tackle climate change this decade will lead to global warming of about 2.4°C this century, far higher than safe levels.
Climate Action Tracker (CAT) said on Tuesday that promises by countries participating in the UN summit in Glasgow to cut greenhouse gas emissions by 2030 will still allow the Earth to warm much more than the UN target by 2100 .
“Even with the all-new Glasgow promises for 2030, we will almost double the emissions required by 1.5°C in 2030,” referring to the aspirational target of warming since pre-industrial levels were set in the 2015 Paris Agreement. will do.”
“Therefore, all governments need to rethink their goals,” said the research coalition.
In an “optimistic scenario” where some countries’ long-term goals to halt the rise in the level of greenhouse gases in the atmosphere – “net zero” – were implemented by 2050 or later, warming could be limited to 1.8C this century. Yes, CAT said.
That forecast echoed an analysis by the International Energy Agency last week.
The CAT cautions against assuming that long-term pledges will be met, however, as most countries have not yet implemented the short-term policies or laws required for those goals.
“It’s great for leaders to claim that they have a net zero goal, but if they don’t have a plan to get there, and their 2030 goals are as low as many of them are, then clearly, These ‘net zero’ targets are just lip service to real climate action,” said Bill Hare, CEO of Climate Analytics, one of the organizations behind CAT.
The world will warm by 2.7C this century, with no new pledges, under “business as usual”, Kat said.
All scenarios will exceed the 1.5C limit that scientists say the world must meet to avert the most devastating effects of climate change.
To keep this up, scientists have said that global greenhouse gas emissions, mostly carbon dioxide from the burning of coal, oil and gas, should fall 45% from 2010 levels by 2030 and reach net zero by 2050.
Greenpeace said the analysis was “disastrous” and called on countries to agree to update their 2030 goals every year until the gap between their pledges and the 1.5C target is closed.
Cat said that about 90% of global emissions are now covered by the net zero target, but the “vast majority” of countries’ climate plans for the next decade are inconsistent with long-term net zero targets.
