The UN-backed ‘Carbon Removal Pioneers’ stoke the development dreams of African countries but crash against the reality of climate science.

Fossil fuel companies that want a free pass to keep pumping oil and gas are making wildly unrealistic promises about 'capturing' their emissions at sites of pollution, or removing them from the atmosphere at later date. But the science says drastic emission cuts are needed now if we are to stay within 1.5ºC warming. Thus ‘net zero’ policies are in reality 'not zero', and effectively guarantee that we’ll overshoot 1.5ºC, triggering catastrophic climate impacts which we have no reason to believe can be reversed by speculative and unproven ‘carbon removal’ technologies.

Technologies for the removal of carbon dioxide (CO2) from the atmosphere (direct air capture, or DAC for short) are already in use, but neither their actual benefits for climate protection nor their other environmental impact have yet to be investigated.

There are several ways to remove carbon from the atmosphere. One is called bioenergy with carbon capture and storage, or Beccs. Here, vast acres of fast-growing plants are grown and then harvested and burned to generate electricity or make biofuel for vehicles.

New research suggests social transformations that prompt “degrowth” could cut humanity’s climate footprint in time to meet the Paris climate agreement target.
