Redefining net zero will not stop global warming
An international group of authors who developed the science behind net zero demonstrate that relying on 'natural carbon sinks' like forests and oceans to offset ongoing CO2 emissions from fossil fuel use will not actually stop global warming. The science of net zero, developed over 15 years ago, does not include these natural carbon sinks in the definition of net human-induced CO2 emissions. Yet governments and corporations are increasingly turning to them to offset emissions, rather than reducing fossil fuel use or developing more permanent CO2 disposal options. Emissions accounting rules encourage this by creating an apparent equivalence between fossil fuel emissions and drawdown of CO2 by some natural carbon sinks, meaning a country could appear to have 'achieved net zero' whilst still contributing to ongoing warming.
