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…
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…
Removing CO₂ from a power station is very different from removing it from the atmosphere. ianrthorpe

There’s more than one way to capture carbon

In his latest article for The Conversation Dr. David Karoly reports on the proceedings of a recent Canberra symposium on “Geo-engineering the Climate”. In his article, Dr. Karoly presents an insightful…
Energy production worldwide has become even more reliant on coal. Joost J Bakker IJmuiden

The emissions juggernaut rolls on, and everybody is on board

DURBAN CLIMATE CHANGE CONFERENCE: A paper published yesterday shows global industrial emissions of carbon dioxide, overwhelmingly from fossil fuels, jumped by 5.9% from 2009 to 2010. This is a big increase…

Carbon capture and storage – a vital part of our climate change response

One of the biggest challenges in our fight against climate change is reducing greenhouse gas (GHG) emissions from the energy sector. Approximately 87% of current global primary energy supplies (and 67…

Carbon leaking from land into streams

Rivers and streams in the United States are releasing substantially more carbon dioxide into the atmosphere than previously…

Where do emissions come from?

Country-by-country estimates of CO2 emissions typically include only those emissions produced from the burning of fossil…

Australia should delay a carbon tax until the rest of the world acts

The big question about the carbon tax is not whether it’s a good or a bad idea in theory. The major issue is whether it makes sense for Australia to implement it at a time of great uncertainty, both in…

Carbon released from forest growth

Dead plant material known as litterfall provides energy to soil microorganisms, leading to a release of stored soil carbon…

Don’t just look to CO2 to slow climate change

Cutting emissions of non-carbon dioxide greenhouse gases could slow changes in climate that are expected in the future. Other…
