Bioenergy Carbon Capture and Sequestration, known as BECCS, is one of the technologies we may need to limit warming to 1.5 degrees.
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.
Without rapid and dramatic changes, the world will face a higher risk of extreme weather and other effects of climate change.

The UN's panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5 degrees Celsius. But these techniques are largely unproven.
Technology exists to capture carbon dioxide from the atmosphere but it has a big cost.

It may be just as well the UK government scrapped its previous carbon capture competition.
Algae could be the key to a new type of biofuel.
The right kind of algae can be converted to biofuel, and there are potential side benefits for carbon capture.

New research calculates the huge cost of 'negative emissions' technologies that will be required to avoid dangerous climate change.
Even the cleanest coal plants add millions of tonnes of greenhouse gases to the atmosphere each year.

Nobody in business wants to touch new "clean" coal plants, which means taxpayers would be left to foot the billion-dollar bills.
Carbon capture is fundamentally flawed. Here's plan B.
The Norwegian capital shows other cities how it's done, by setting out a tailor-made plan to reduce emissions to zero by 2030.
Carbon capture and storage can clean up coal power.

Despite advances in technology, carbon capture and storage could be unsettled by renewable upstarts.
Working out how Mars's carbon dioxide was turned into rock could help with carbon capture efforts on our own planet.
A new method for creating a form of graphene with carbon dioxide sucked from the air has been announced with misleading claims.
Replanting forests is one way to remove carbon dioxide from the atmosphere. This is a site in China.
New research shows that we'll have to remove carbon from the atmosphere for any chance of keeping warming below 2C.

What to make of the announcement that we'll be off the hydrocarbons in time for the 22nd century? Dream on.
Countries should make pledges to fund low-carbon research - such as developing solar technology - and development as part of global climate talks.

Countries will take emissions reduction pledges to international climate talks in Paris at the end of this year. Those pledges should also include funds for low-carbon R&D.
Coal seam gas is only one issue for managing one of Australia’s most important geological resources.

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…
Investing in fossil fuels for the long term? You might find your plans get pricked.
The controversy ignited by the Australian National University in October, when it decided to sell its shares in seven resources companies, has raised two important questions about divestment from assets…
Could carbon capture and storage be the way to clean up coal power stations, such as this one in Australia’s Latrobe Valley?
To have any chance of avoiding dangerous climate change we’ll have to reduce the carbon emissions from our energy sectors — currently the largest human source of greenhouse gas emissions globally. And…
A sponge like polymer for adsorbing carbon dioxide in power plant flue gas has been developed. Previous substances for carbon…
The new budget has served up a big hit to Australia’s environment.
Budgets are often framed as give and take. But in the case of the environment, the government is taking large amounts of money in cuts, while giving little back beyond funding the Direct Action climate…
