This is the best summary I could come up with:

A key plank of the UK government’s defence against the biggest climate legal action in the world next week has fallen away as a result of the U-turn by the prime minister, Rishi Sunak, on green policies.

They will argue in the grand chamber of the Strasbourg court that the nations’ policies to tackle global heating are inadequate and in breach of their human rights obligations.

Lawyers representing the six young people taking the legal action are to present evidence that the current policies of the 32 countries mean the world is on track to reach 3C of global heating within their lifetimes and argue that the governments’ failure to act quickly enough to reduce emissions breaches the human rights of their clients.

But the retreat this week on several key policies designed to ensure the UK meets its future carbon budgets and its legal obligation to reach net zero by 2050 has brought the government into direct collision with the committee.

Aged from 11 to 24, the six Portuguese claimants say they were driven to act by their experiences in the wildfires that ripped through the Leiria region in 2017, killing 66 people and destroying about 20,000 hectares (50,000 acres) of forest.

Crowdfunded by people around the world who have donated more than £100,000, they are seeking a binding ruling from the judges to force the countries to rapidly escalate their emissions reductions in what would be a historic milestone in climate litigation.
