Not a single G20 country is in line with the Paris Agreement on climate, analysis shows - CNN

The watchdog Climate Action Tracker (CAT) analyzed the policies of 36 countries, as well as the 27-nation European Union, and found that all major economies were off track to contain global warming to 1.5 degrees Celsius above pre-industrial levels.

CAT reported that progress had stalled after dozens of world leaders made ambitious new pledges to slash greenhouse gas emissions during the US President Joe Biden's Climate Leaders' Summit in April.

"In May, after the Climate Leaders' Summit and the Petersburg dialogue, we reported that there appeared to be good momentum with new climate action commitments," said Niklas Höhne, a founding partner of the NewClimate Institute, a CAT partner.

"But since then, there has been little to no improvement: nothing is moving," he said.

"Anyone would think they have all the time in the world, when in fact the opposite is the case."

Six countries, including the UK, have an overall climate policy that is "nearly sufficient," according to the report, meaning they are not yet consistent with 1.5-degree alignment but could be with small improvements.

These countries need to rethink their choice," said Bill Hare, CEO of Climate Analytics, another CAT partner.

The continued use of coal remains a significant policy problem, the report found, with China and India retaining huge coal pipelines.

This causes temperatures to rise and drives more extreme weather, ice melt, sea level rise and ocean acidification.

To keep the warming under 1.5 degrees, the world needs to reach net zero by 2050, a landmark UN climate science report published in August showed.

"An increasing number of people around the world are suffering from ever more severe and frequent impacts of climate change, yet government action continues to lag behind what is needed," said Bill Hare, the CEO of the think tank Climate Analytics and another author of the analysis.
