About the project

Many studies have quantified GHG emissions from cars and car travel. Syntheses are hampered by the use ofdifferent methods, delimitations, and assumptions. This study instead provides an overview via modeling. The future climate impact of Swedish car travel is analyzed for scenarios where the path to climate neutrality goes through electrification and biofuel use, to varying degrees. Emissions from production and use of cars, electricity and fuels are considered, and also the CO2 exchange between land and atmosphere, which is critical for the climate impact of biofuels.

Climate impact are described with a method that show in an easily understandable way how car travel affects global warming over different time horizons, and how warming depends on whether CO2 emissions originates from fossil fuels or biofuels. The aim is to improve the understanding of issues that complicates discussions on different paths to climate neutrality.

The project has a reference gruop consisting of Jakob Lagercrantz, the Swedish 2030-secretariat; Anna Elofsson head secretary for SOU 2019:04 (The Swedish Government Inquiry on the phase-out of fossil fuels and a petrol and diesel car sales ban); Anna Widerberg and Andrea Egeskog, Volvo Cars; Tomas Kåberger, Swedish Climate Policy Council and Anette Cowie, IEA Bioenergy and University of New England, Ausrtalia. The reference group will mainly be involved in teh scenario construction and assessment.
