While new buildings may be the glamorous eco-home pinups, retrofitting existing homes is the main game when it comes to creating energy-efficient, comfortable housing stock for all Australians.
The federal government's keenly awaited review of Australia's climate policies continues a longstanding bipartisan traditional of weak policy development in this area.
After three years in which global carbon emissions scarcely rose, 2017 has seen them climb by 2%, as the long-anticipated peak in global emissions remains elusive.
Consumers need to educate themselves on costs of eating beef and start thinking about choosing low-carbon foods instead.
The federal government has announced a new National Energy Guarantee focused on electricity reliability, after deciding not to implement a clean energy target.
New data from a NASA satellite show in unprecedented detail the flow of carbon dioxide into the atmosphere. Future satellites should even be able to detect the signatures of individual power stations.
Imagine a world ravaged by the fallout from nuclear weapons and the runaway effects of climate change. Congratulations, you've just imagined the Plutocene, but let's hope it doesn't become a reality.
It's still possible to hit the more ambitious of the two Paris global warming goals, according to a new estimate of the global carbon budget. But it sure won't be easy, and we need to start now.

Tonight on the ABC's Catalyst, scientist Tim Flannery asks if seaweed can save the world. It's a bold claim for algae, but seaweed could play a key role in keeping climate change in check.
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
The Finkel Review looks likely to recommend a "low emissions target", which would award credits to cleaner energy sources, much like the current Renewable Energy Target.
Online shopping giants and logistics firms are trying to improve efficiency and cut carbon – knowing that doing so will reduce their operating costs while appealing to green-minded consumers.
A survey of executives in high-emitting industries such as mining and electricity generation suggests they are not engaging with the government's flagship policy to cut greenhouse emissions.
Carbon capture and storage gets a bad rap from its associations with 'clean coal'. But the technology could prove vital in cutting emissions from other industries like steel, cement and chemicals.
Hazelwood power station will this week fall silent after a half-century during which it went from a beacon of progress to an emblem of fossil fuel pollution.
Donald Trump has signalled the end of US leadership on climate policy, with potentially unpleasant consequences for America's economy, security and diplomatic standing.
Leaders are worried US leadership on global issues like climate change will be diminished under President Trump. Experts explain why China is ready to lead, and how that could be a good thing.
Australia's plan to bring fuel efficiency standards up to par with the US and Europe could see us say goodbye to regular unleaded, and hello to a useful way of cutting our rising greenhouse emissions.
If Donald Trump turns away from climate action as George W. Bush did, Europe and China can respond by forming an alliance that will turn the United States from a climate leader into a follower.
