The latest UN climate report makes it clear that the task of limiting climate change is urgent and huge. We must start to transform our economy today, but it will bring rewards as well as challenges.
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.
Painkillers and life jackets are two of the many products that depend on carbon dioxide.
Canada wants to move towards a green economy and meet its Paris Agreement targets, but it has also just taken ownership of a pipeline. How can the federal government deal with this paradox?
Why go to all that bother when you can just half-fill the kettle?
New research calculates the huge cost of 'negative emissions' technologies that will be required to avoid dangerous climate change.
Can Poland reduce its dependence on cheap and dirty domestic coal power?
Carbon capture and storage gets a bad rap from its associations with 'clean coal'. But the technology could prove vital in cutting emissions from other industries like steel, cement and chemicals.
Many believe we can stabilise the power supply by asking customers to help - but there's a problem.
The idea of clean coal has been around for 40 years, but remains a pipe dream.
Scholars of communications pick apart the rhetoric behind the 'war on coal' and explain why it ultimately benefits the coal industry.
The Norwegian capital shows other cities how it's done, by setting out a tailor-made plan to reduce emissions to zero by 2030.
Despite advances in technology, carbon capture and storage could be unsettled by renewable upstarts.
Storing waste CO2 in rock? Results from a test site at a geothermal plant in Iceland show that CO2 mixed with water can be turned into minerals in locations with basalt volcanic rock.
An Icelandic trial shows carbon dioxide can be pumped underground and stored as rock.
Working out how Mars's carbon dioxide was turned into rock could help with carbon capture efforts on our own planet.
Countries have signed up to the Paris climate deal, but they have not yet promised the necessary cuts to emissions.
New analysis reveals carbon capture at coal power plants is significantly more expensive than thought, making renewables and natural gas power generation more attractive.
New technique captures 78% carbon using molten tin.
A technology designed to reduce the effect of fossil fuels on the climate has received £1 bln in subsidies and has nothing to show for it.
