'Net Zero' requires a balance between emissions of carbon dioxide and other greenhouse gases into the atmosphere the and removal of those gases from the atmosphere.
Until we achieve Global Net Zero the climate problem will continue to worsen. The longer it takes until we achieve Net Zero, the more climate damage will be done to ecosystems and society. If we achieve Net Zero quickly, we will limit the amount of climate damage that we cause and reduce the amount of carbon dioxide that we will need to remove from the atmosphere.
In 2018, the Intergovernmental Panel on Climate Change's special report Global Warming of 1.5 ºC emphasised the urgency for achieving net zero global emissions by around 2050. Since then, countries, cities and businesses have made net zero pledges, but what exactly does ‘Net Zero’ mean?
This site brings together the best available research on pathways to Net Zero. We are tackling questions on how to measure, define, and achieve Net Zero - this will require both major interventions to reduce emissions and ways to remove carbon dioxide from the atmosphere and store it away permanently.
