First you establish massive tree plantations around the world. The trees suck CO2 out of the atmosphere as they grow. Then you harvest the trees, churn them into pellets, burn them in power plants to generate energy, capture the carbon emissions at the chimneys and store it all underground where it can never escape. Voila: a global energy system that produces ‘negative emissions’. This technology is known as BECCS: bio-energy with carbon capture and storage.
