The Final 25%: How to tackle hard-to-reach emissions

Electricity, transport, and heating account for a massive 80% of greenhouse gas emissions and are at the forefront of the battle to achieve Net Zero. But reaching Net Zero means also dealing with the hard-to-reach 20% of emissions: agriculture, plastics, cement, and waste, and extracting at least 5% extra from the atmosphere to account for the emissions that we simply cannot get rid of.
