Policy brief on climate engineering
2016 (English)Report (Other academic)
Climate engineering (geoengineering) has been widely discussed as a potential instrument for curbing global warming if politics fails to deliver green house gas emission reductions. This debate has lost momentum over the last couple of years, but is now being renewed in the wake of the December 2015 Paris climate change agreement. Resurgent interest primarily stems from two elements of the Paris agreement. First, by defining the long term goal as “achiev[ing] a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases” instead of decarbonization, the agreement can be interpreted as providing leeway for climate engineering proposals. Second, the agreement formulated a temperature goal of “well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C”. In response, several scientists argued that these goals may require climate engineering.
As these discussions will affect the forthcoming review of pathways toward 1.5°C warming, this policy brief takes stock of climate engineering. It draws on the expertise of Linköping University’s Climate Engineering (LUCE) interdisciplinary research programme. The brief provides an overview of the status of academic debate on climate engineering regarding bioenergy with carbon capture and storage (BECCS); stratospheric aerosol injection; and mass media reporting and public engagement.
