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

In a new blog post at @voelkerrechtsblog.org, I discuss the implications of the ICJ's Advisory Opinion for corporate climate accountability.

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.

A New South Wales court has blocked the expansion of a coal mine because of its global climate harm.

I had hoped - but not expected - that the Court would mention this. It did. These comments stand out in an already very strong AO.

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

This is big (and bad) news: New Zealand's government has withdrawn from the Beyond Oil and Gas Alliance, which a previous NZ government joined at the Glasgow climate summit in November 2021.

NZ pulls out of global coalition for phasing out fossil fuels

The move follows the Budget announcement of $200 million to support new drilling for fossil fuel fields.
