Bioenergy Carbon Capture and Sequestration, known as BECCS, is one of the technologies we may need to limit warming to 1.5 degrees. from

Bioenergy carbon capture: climate snake oil or the 1.5-degree panacea?

Delays on climate action to reduce emissions means that we may have to consider technologies that strip carbon dioxide from the atmosphere. But that will come at a cost.

Coal seam gas is just the latest round in an underground war

In a recent article on The Conversation, Queensland coal seam gas (CSG) researchers argued that the industry is progressing faster than the science, leading to concerns over fugitive emissions and impacts…

Explainer: how much carbon can the world’s forests absorb?

You are walking through the bush when you see an enormous tree trunk, tens of metres long, lying across the forest floor. Imagine you and several dozen friends lifting it by hand. Now you’ve literally…
Restoring our southern wetlands as carbon farms would have many additional benefits to the ecosystem and the public. Catherine Lovelock

Carbon farming could restore Australia’s southern coastal wetlands

Australia’s southern coastal wetlands are more diverse than most people realise. In a recent paper, Paul Boon suggests they provide valuable ecological services that exceed those of inland wetland ecosystems…
Our national parks are full of forests - we could be claiming carbon credits for managing them better. Tatiana Gerus

Which of our forests should be managed for carbon?

The Australian Government has recently committed to a second round of the Kyoto Protocol to run from 2013-2020. In doing so, Australia is required to reduce its greenhouse gas emissions by at least 5…
The deadline for the US budget sequester —which will see across-the-board spending cuts of $US 85 billion implemented over the fiscal year — is rapidly approaching. AAP

No silver lining to US budget sequester

The first thing you should know about the sequester is that nearly everyone agrees that it’s a bad idea. In fact, that was the point. In the summer of 2011, with congressional Republicans refusing to raise…
The Coalition’s proposed alternative to “the great big new tax” relies on storing carbon in trees and soil. AAP Image/Mick Tsikas

Will the Opposition’s Direct Action Plan work?

The Coalition has promised that if it takes government in September, it will get rid of the price on carbon emissions established by the Australian Labor Party. In its place, the party will implement a…
An early season burn in Arnhem Land. Low intensity fires decrease greenhouse emissions and increase carbon stored in trees. Brett Murphy.

Savanna burning: carbon pays for conservation in northern Australia

Fire and biodiversity have a complex relationship in northern Australia. Tim Flannery and others blame the current northern biodiversity crisis, at least in part, on changed fire regimes. Improving fire…

Ash to ashes – what could the 2013 fires mean for the future of our forests?

In the high country of Victoria, firefighters are presently battling a large bushfire that is moving through the forests south of Harrietville and past the second highest mountain in Victoria, Mt. Feathertop…
By opting for restraint in his state of the union speech, Obama presented his ideas not as bold initiatives to revive the liberal tradition, but as pragmatic proposals with widespread bipartisan support. EPA

Obama extends a light hand of liberalism to Americans

Barack Obama opened his fourth state of the union address to Congress with words from another Democratic president, John Kennedy: “The Constitution makes us not rivals for power but partners for progress…
Cement manufacture is a substantial producer of emissions, and we’re using ever-more concrete. Something has to change. Eduardo MC/Flickr

Eco-cement, the cheapest carbon sequestration on the planet

Cement production is one of the dirtiest industrial processes on the planet. It produces nearly 9% of global carbon emissions. This increases every year with the extraordinary demands for building materials…
It may not be a silver bullet, but biochar has a lot to offer farmers (and the atmosphere). sillypucci/Flickr

Backing biochar: the Australian Government’s role

Evelyn Krull, a research scientist at the CSIRO, asked in these pages whether biochar could save the planet. Eighteen months have passed and although research efforts continue, still no meaningful quantities…

The charcoal challenges: fire and climate dynamics

The United Nations Environment Programme (UNEP) is co-ordinating a new venture to tackle short-lived global warming agents such as black carbon. Should we be paying more attention to black carbon? Yes…
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…
