A much-anticipated report from the world’s leading authorities on climate change has reignited a debate over the usefulness of the “carbon budget.”

The concept refers to how much carbon dioxide can be emitted before temperatures rise beyond a given threshold. The idea is that informing world leaders about how much carbon will cause a tipping point can help design policies that will prevent the globe from crossing that threshold. And it also helps scientists keep track of how quickly the threshold is approaching.

But some experts suggest that, although scientifically useful, the carbon budget may not actually be promoting climate action among policymakers.

They say the international community should focus less on how much carbon can still be emitted and more on setting concrete timelines for transitioning to a net-zero carbon world. This would be a shift from the current terms of the Paris Agreement, which includes a global temperature target but no specific timeline for collectively cutting emissions.
