With an election possible next year, the Labor leader is faced with a near unsolvable puzzle.
A ground-breaking court case in the Netherlands could influence the way Canadian courts rule on the government's actions on climate change.
'Carbon sinks' like forests and the soil have already been factored into the carbon budget – they should not be double-counted.
The long-awaited paper sets a positive tone. But it's not clear if the government grasps the sheer scale or urgency of the emissions reduction task.
Canada keeps revising and updating its emissions targets, diverting attention from its failures to make any progress at all.
In all the strategies and tactics of the climate wars, the most disturbing development is that the carbon pricing became roadkill.
Making better use of existing building space is a neglected but essential way to cut our carbon emissions. The key is human behaviour. Good low-carbon citizens will help create good low-carbon cities.
Australia's new emissions data for the December 2018 quarter show a rise on the previous quarter, although the raw figures actually dropped. Here's what that all means.
Australia’s international reputation depends on rejecting the use of Kyoto carry-over. More importantly, so does our climate.
New Zealand's government has released a bill that sets targets to bring long-lived greenhouse gases to net zero by 2050 and reduce emissions of the shorter-lived methane by 10% within a decade.
Contrary to the advice of the UK's climate advisers, aiming for net zero before 2050 is credible – but the country must reassess how much its future is worth.
A new petition is urging state and federal governments to rein in Australia's rampant land clearing, which worsens the risk of bushfires and threatens to undo the work of the Emissions Reduction Fund.
Australia's government insists it is on track to surpass its emissions reduction commitments under the Paris Agreement. But while that may be true, it will only happen with some clever accounting.
Australia's commitments to cut emissions are on a collision course with urban growth. We need a much more comprehensive strategy to make the transition to a sustainable built environment.
The Labor Party's newly announced energy policy could finally set Australia's electricity sector on the path to a renewables-driven future. But policies are still needed to cut emissions elsewhere.
The federal government is primarily to blame for the mess that is Australia's energy policy. It's time for the states to step up, to reduce both prices and emissions.
The latest UN climate report makes it clear that the task of limiting climate change is urgent and huge. We must start to transform our economy today, but it will bring rewards as well as challenges.
The world needs to be carbon-neutral by mid-century to give ourselves a chance of holding global warming to 1.5C. With around 1% of the global carbon budget, Australia needs to rapidly do its share.
The late Sen. John McCain was an early – and lonely – Republican supporter of action to fight climate change. His challenge was to regulate sources of energy that underlie much of our economy.
Renewable energy investment is gathering steam throughout the world. Australia's National Energy Guarantee policy should be made agile enough to jump on board, because this runaway train won't stop.
