Unwise to depend on future carbon removal, while continuing to emit CO2

Schemes to suck up carbon emissions and permanently remove it from the atmosphere will be essential, as humanity is unable and unwilling to cut its carbon emissions. The techniques to be used to remove carbon are CCS (carbon capture and storage), Beccs (bioenergy with carbon capture and storage – with huge potential negative impact on land use and biodiversity) and Daccs (Direct Air Capture with Carbon Capture Storage). But they will have the effect of allowing the continuation of “business as usual” and preventing the drastic carbon reductions that are needed, now and the the near future. There is not going to be the capacity, let alone the ability or willingness to pay for it, to permanently store the billions of CO2 necessary. Yet sectors like aviation are depending on these unlikely, unproven technologies, in order to continue to emit carbon for years, with almost no reduction in emissions.  Regrettably the inclusion of future carbon removal technologies in the IPCC’s models is encouraging policymakers to treat carbon removal technology as a fait accompli and delay essential emissions reductions policies. .Tweet   Why we should remain sceptical about carbon removal 8th April 2022 Schemes to suck up carbon emissions may be essential, but some fear they could be letting politicians off the hook. By India Bourke (New Statesman) Imagine that burning fossil fuels is the equivalent of smoking, and that the resulting climate crisis is lung cancer. In the range of available treatments, the best option is to reduce reliance on cigarettes as speedily as possible – or, in climate terms, to reduce energy consumption and speed up the transition to renewable sources. Sometimes, however, either it is impossible for the smoker to stop, or too much damage has already been done, and medical intervention is needed. In the energy analogy, such efforts fall under the category of so-called “carbon removal”. In the world’s race to reach net-zero emissions, “carbon removal is essentially your safety net,” says Jonny Peters from the think tank E3G. Not all sectors will be able to reduce their emissions as far or as fast as science requires; technologies that can mop up excess carbon will be necessary to uphold industries such as aviation, agriculture and concrete production. Carbon removal may also one day be used to achieve “net negative”, whereby more emissions are removed than emitted, Peters adds. Options for carbon removal range from nature-based solutions – such as forest protection, restoring peatland and whale conservation – to speculative high-tech machines and processes. Potential technological fixes include bioenergy with carbon capture and storage, known as Beccs, which involves burning wood, vegetation or waste for power, capturing the carbon dioxide and storing it underground (as piloted by the UK power station Drax). Meanwhile, direct air capture (Dac) sucks carbon from the atmosphere before it is stored underground. The world’s biggest Dac project opened in Iceland last ye
