Abstract

Syftet med denna översiktsrapport är att ge en nulägesbild av möjligheterna till storskalig reducering av koldioxidutsläpp och atmosfäriska koldioxidkoncentrationer genom olika former av NET (Negative Emission Technologies). Enligt 2014 års basscenario från IPCC för maximalt 2°C uppvärming måste de globala koldioxidutsläppen börja minska kraftigt i närtid samt att olika former av NET tas i bruk senast under åren 2030–2045. NETs kritiska roll för måluppfyllnad kan ses i IPCCs scenariodatabas. Utav de 113 scenarier associerade med utfall under 2°C förutsätter 107 av dessa en framgångsrik implementering och storskaligt upptagande av koldioxid både ur själva atmosfären och direkt från olika typer av utsläppskällor. Vår övergripande slutsats är att utifrån nuläget på den tekniska utvecklingen kommer 2 graders målet svårligen uppnås. För att nå måluppfyllnad behövs en kontinuerlig minskning av absoluta utsläpp, att en marknad skapas för koldioxid och en betydligt snabbare utevcklingstakt vad gäller NET, exempelvis genom ökat statligt R&D.
