Forget the hostile Congress – Obama can cut global climate deals on his own terms

Much has been made of the domestic political roadblocks between US President Barack Obama and climate action. But by using existing treaties he can get around the hostile Congress and help cut global emissions.

New UN rules put the spotlight on climate laggards to lift their game

Countries that drag their feet on climate action have fewer places to hide these days. Rules brought in at the 2014 Lima talks require them not just to set targets, but to publicly justify them too.

Obama takes ‘biggest step’ on US climate policy: experts react

US President Barack Obama's new climate plan aims to cut greenhouse emissions from the nation's coal-dominated power sector by 32% by 2030. Will it get through, and how will it affect this year's climate talks?

Australia can stop greenhouse gas emissions by 2050: here’s how

To avoid dangerous climate change there is a finite amount of greenhouse gas emissions, in particular CO<sub>2</sub>, that we can add to the atmosphere - our global carbon budget. If we use our budget wisely, we have until about 2050 to transition to zero net emissions. But how do we get there?

Australia’s ‘climate roundtable’ could unite old foes and end the carbon deadlock

The Australian Climate Roundtable unites business, environmental and social groups in calling for a strong climate policy. This unprecedented show of unity might even break down Canberra's climate stalemate.

Greenhouse emissions from the aviation industry are still largely unregulated. The prospect of regulations for US flights sounds like progress, but it won't happen without an elusive international consensus.
