Carbon offsetting is often met with scepticism, but a new report suggests that if correctly designed it can be an important part of the net zero transition.

The cost of deploying a direct air capture unit must fall while the cost of emitting CO₂ rises.
A climate scientist looks at what works and some popular ideas that aren’t as cheap or effective as people hope.
From pulling carbon dioxide out of the air to turning water into fuel, innovators are developing new technologies and pairing existing ones to help slow global warming.
Wind turbines often can produce more power than is needed for electricity onshore. That extra energy could be put to work capturing and storing carbon.
Klaus Lackner is finding new ways to cut the technology’s high costs and energy demand, and he’s about to launch the first ‘mechanical tree’.
Most carbon dioxide captured in the U.S. today is used to extract more oil. Two scholars point to another way: biological sequestration.
An engineered climate recovery needs to be taken seriously — in addition to cutting emissions.
CO₂ is used in a range of industries, from food production to pharmaceuticals.
Machines using giant fans and filters can literally suck carbon dioxide out of the air. Sounds great – but the technology faces many challenges.
Carbon Engineering’s clever harnessing of high-school chemistry is just a small step on the path to negative emissions.
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.
