The startup Gigablue announced with fanfare this year that it reached a historic milestone: selling 200,000 carbon credits to fund what it describes as a groundbreaking technology in the fight against climate change . But outside scientists frustrated by the lack of information released by the company say serious questions remain about whether Gigablue’s technology works as the company describes. Their questions showcase tensions in an industry built on little regulation and big promises — and a tantalizing chance to profit.

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.

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