A company in Iceland captures carbon right out of the air and injects into the earth, the operation is a working proof that we can take carbon out of thin air. The carbon capture and storage (ccs) process is one of many options we have as a species to advert our own demise. With COP26 starting next week we not only need to get politicians to enforce policies to help the environment (like cutting market manipulating polices like oil subsidies) but to invest in building ccs solutions.
The Economist magazine (which is incredibly slow in acknowledging the world changes) has a good article exploring the state of ccs and what options we have. There are multiple solutions and we should explore them all.
Without a doubt our focus should be on reducing carbon emissions, but there’s no reason we can’t reduce our carbon output while also looking into capturing it.
The negative emissions is held to offer play two roles in climate stabilisation. One might be seen as balancing the current carbon account. Although most emissions can theoretically be eliminated using technologies that exist now, aviation, shipping and some industrial processes remain hard to decarbonise.Some agricultural greenhouse-gas emissions look as if they will prove recalcitrant. As long as emissions of long-lived greenhouse gases persist, stabilisation will require negative emissions.
The other role for is getting rid of historical excess. As we have seen, the cumulative CO2-emissions budget consistent with a 50-50 chance of meeting the 2°C goal is 3.7trn tonnes. The budget for 1.5°C is just 2.9trn tonnes. With 2.4trn tonnes already emitted, that leaves a decade of emissions at today’s rates for 1.5°C, maybe 25 years for 2°C.
