Xi Jinping announced China's new climate targets personally, a positive gesture, but the targets brought little clarity on China’s future emission pathway. Targeting a 7-10% emission reduction by 2035 from an undefined "peak level" undersells China's current clean energy boom.

The announcement also gains further currency when considering the other major news today, with the 2025 Production Gap Report finding that fossil fuel-producing countries are still continuing to expand production, thereby undermining the achievement of the 1.5C goal

Though the Court doesn't say much explicitly, the key is to read between the lines.

It has been a decade since the Paris Agreement.

And with COP30 in Brazil on the horizon, there have been calls for major reform at the UN climate talks.

We asked 16 experts - including former negotiators and COP veterans - what they think should change at these events.

52/🚨The Court then delivers a powerful statement: failure of a state to take appropriate action to regulate fossil fuel consumption, the granting of fossil fuel licences, fossil fuel subsidies may constitute an internationally wrongful act which is attributable to that state
