The dangers of Blue Carbon offsets: from hot air to hot water?

COP23 briefing - There has been much talk of "Blue Carbon" in the Bonn climate negotiations. But what does it really mean? This briefing sets out the issues and finds that the use of blue carbon to offset and hence effectively avoid required emission reductions in other sectors would undermine our ability to limit temperature rise to 1.5°C.

EU Coal Phase Out

When should the EU shut down its 300+ coal plants to meet the Paris Agreement's long-term temperature limit? Our report outlines a science-based schedule for a coal phase-out in Europe.

Ratification Tracker

The Paris Agreement has entered into force in November 2016, when the double threshold of 55 countries and 55% global emissions was crossed. We continue to track the progress of ratification on this page.

Big change after the big storm: Post-disaster transformative adaptation in Small Island Developing States

Presenting a disaster as an ‘opportunity’ is clearly a sensitive and emotive issue. But when an energy infrastructure is in tatters should we not view this as a chance to make a fundamental transition to a low carbon future? When will there be a better opportunity to relocate essential services away from high risk areas than when they need rebuilding? When do we consider what we truly value more than when we have suffered loss?

As Climate Negotiators Debate Nations' Pledges, Scientists Worry It's Not Enough

As Climate Negotiators Debate Nations' Pledges, Scientists Worry It's Not EnoughNPR

Governments are wrapping up a meeting in Bonn, Germany, to figure out how to implement a global climate agreement. The conference has focused on the pledges to reduce greenhouse gas emissions, which nations made two years ago in Paris. But even as negotiators debate the details, scientists are warning that carbon dioxide levels are again on the rise, and the efforts in Paris may not be enough.

Climate action by China, India to offset Trump: study

Climate action by China, India to offset Trump: studyReuters

BONN, Germany (Reuters) - Global warming is likely to be slightly less severe than previously expected thanks to stronger climate policies by China and India that will offset less U.S. action under President Donald Trump, a study showed on Wednesday.

There have been proposals for the UNFCCC to adopt a dual-term greenhouse gas accounting standard: 20-year GWPs alongside the presently accepted 100-year GWPs. It is argued that the advantage of such a change would be to more rapidly reduce short term warming and buy time for CO2 reductions. This briefing shows why these changes would be counterproductive and the benefits overstated.
