Nice when a few sandstone houses get smoking, but what are people breathing in bigger rural towns where wood stoves are common? Flickr/welshmackem

Should we worry about winter chimney haze in rural towns?

Winter in many Australian country towns is accompanied by a pall of smoke from wood-fired heaters that lasts from late afternoon to the following morning. In larger towns and cities burning wood has been…

Australia under a carbon price plan: Q+A with Ross Garnaut

Tomorrow Australia will place a price on carbon. The former climate change adviser to the Federal Government, Ross Garnaut, a Professorial Fellow in Economics at the University of Melbourne, led the push…
This is carbon. The carbon you keep hearing about on the news is probably carbon dioxide. It doesn’t look like this. Rui Costa

What is ‘carbon pollution’ and why are we trying to stop it?

You’ll doubtless have heard Australia is introducing a “carbon tax” this Sunday to reduce “carbon pollution”. What is being controlled is not just any carbon but emissions of a specific gas, carbon dioxide…
The media tends to portray Chinese achievements as lacking credibility. Trey Ratcliffe

Does the Chinese emissions ‘error’ matter?

Recent analyses that China’s carbon dioxide (CO₂) emissions might be 1.2 gigatonnes or 20% higher than previously estimated have generated something of a feeding frenzy in the media; and not just the daily…
China’s emissions keep increasing, but it’s burning less fuel for every increase in GDP. Bert van Dijk

IEA reveals emissions are up again, but it’s not all bad news

The numbers are just in. At a time when we need to be urgently reducing our CO₂ emissions, we are now emitting more than at any time in human history. However, it’s not too late to turn things around…
We need a more intelligent discussion about how to use our finite carbon, and it needs to be about metal. AAP

Treasure your metal: why we need to respect embedded energy

The recent furore about the carbon tax in this country has not been a celebration of enlightened debate. I think much of the debate misses a vital aspect of carbon use, namely, that using carbon to make…
State governments are walking away from emissions reduction, but it’s thanks to poor policy from the ALP. Takver/Flickr

A flawed carbon pricing scheme lets states dump climate action

In the past few days we have seen two states, Victoria and Queensland, announce cut-backs on action to reduce greenhouse gas emissions. They have been able to justify this by pointing out, correctly, that…
Melting Arctic Sea ice should be the warning we need about expanding coal exports. Michael Sonnabend

On Arctic Sea ice melt and coal mine canaries

Despite peak global temperatures in 2005 and 2010 (unprecedented in the instrumental record), a recent sharp plunge in volume of the Arctic Sea ice and a spate of extreme weather events, coal mining, coal…
There are limits to the amount of carbon dioxide plantations can absorb. David Clarke

How much carbon can trees absorb?

Australia’s agriculture and forestry - land-based abatement - can make a valuable contribution to lowering Australia’s greenhouse emissions. The scale of contribution has been widely discussed. But the…
Emissions spiked, thanks to more intensive energy use. Louis Vest

The emissions rebound after the GFC: why greenhouse gases went up in 2010

Recessions are not the way to permanently cut greenhouse gas emissions. Global emissions surged during 2010, cancelling out the reductions from the global financial crisis (GFC). Emissions took off in…
Looking at how other jurisdictions, such as Germany, are reducing emissions can help guide Australian policy. AAP

What Australia can learn from the world’s best de-carbonisation policies

Around the world an increasing number of detailed policy road maps are demonstrating the possibility, necessity and urgency of a rapid transition to a just and sustainable post carbon future. The key barriers…

Intelligent design: time to wise up and build for the climate

There may be no belching smoke stacks to be seen, but every time we thoughtlessly put up a poorly designed structure or resort to energy-intensive solutions to cool, heat, and operate an inefficient building…

The rise of diesel: but how cheap and clean is it?

Like many countries, Australia is seeing a growth in the number of diesel vehicles on our roads. Since 2006 the number of registered diesel vehicles has increased by a remarkable 40%; diesel passenger…
Some jurisdictions are pushing for aviation emissions controls, but an international agreement seems far away. Cardiff Friends of the Earth

See you in court: solving aviation emissions is an international mess

Aviation is a growing source of emissions. Emissions from aviation are increasing against a background of decreasing emissions from many other industry sectors. Airlines - with their international reach…
