The 2nd International Conference on Negative CO2 Emissions
A new date for the conference has been set: June 14-17, 2022!
The objective of the Paris Agreement is to limit warming to well below 2ºC, and to pursue efforts to limit the increase to 1.5ºC. The carbon budget is the amount of carbon dioxide that we can emit while still limiting global temperature rise to a given level.
The exact size of the carbon budget is uncertain. This said, the remaining budgets for limiting warming to 1.5ºC or 2ºC have been estimated at about 420 and 1170 Gt of CO2 from the end of 2017. With unchanged present emissions at about 40 Gt CO2/year these budgets would be exhausted 10 and 30 years later. Most of the IPCC emission scenarios that meet a global two-degree target overshoot the budget at first and then remove the excess carbon with large negative emissions, typically on the order of 400-800 Gt CO2 up to 2100.
At the same time as negative emissions appear to be indispensable to meet adopted climate targets, the large future negative emissions assumed in climate models have been questioned and warnings have been raised about relying on very large and uncertain negative emissions in the future. With the future climate at stake, a deeper and fuller understanding of the various aspects of negative emissions is needed.
The purpose of the conference is to bring together a wide range of scientists, experts and stakeholders, in order to engage in various aspects of research relating to negative CO2 emissions. This includes various negative emission technologies, climate modelling, climate policies and incentives.
