Carbon Dioxide Removal is the latest buzz phrase in the climate world. The IPCC tell us it will be essential to meet the goals of the Paris Accord. But it's easier said than done! Now a new study proposes copying the way nature creates seashells, so that we can durably store billions of tonnes of carbon in solid rocks on the seabed. So, can Ocean Carbon Dioxide Removal save the day?

Can we solve our atmospheric carbon problem AND get something useful from it at the same time? Sounds better than just shoving it underground like Carbon Capture and Storage (CCS) projects are planning, doesn’t it?

Carbon - in the form of carbon dioxide - is something that we have way too much of in the atmosphere at the moment. And carbon is also in a whole bunch of useful products ranging from diamonds to plastics to fuels. People are starting to figure out how we can make all kinds of products from captured carbon... but should we?

In this video I talk with Dr Jessica Allen about all the things you can make out of captured carbon, and assess each one in terms of their potential to be cheap, valuable, scalable and permanent.

The Liberal plan to incentivize companies that invest in carbon-capture technology was met with applause from Alberta’s oil and gas industry, but some environmental advocates say the money could’ve been better spent on a faster transition to green energy.

Once a fringe idea, carbon capture and storage has become a key part of decarbonisation plans the world over. Supporters argue that we need a way to remove CO2 already in the atmosphere to stay below 1.5C of global warming. But does this technology risk providing big polluters a license to carry on as normal? The FT weighs the pros and cons. Read more at https://on.ft.com/3jc8iDS
