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…

Australian car industry needs lower emissions, not handouts

The Australian Government has been bailing out automotive manufacturers since 1985. Both that year’s Button Plan and the 2008 Bracks Report recommended restructure and additional funding. But unless the…
An ice-free world isn’t impossible – even though it seems the stuff of science fiction. Alistair Knock

As emissions rise, we may be heading for an ice‑free planet

Last December’s meeting of the American Geophysical Union featured three of the world’s leading climate scientists: James Hansen (NASA’s chief climate scientist), Elco Rohling (National Oceanography Centre…
Is Australia going down the East Asian high-rise route? eugenewei

The carbon devil in the detail on urban density

How dense could we be? Very, if you follow much of the commentary in Australian debates about the way we should plan our cities. High-rise residential developments have been springing up in all Australia’s…
