Researchers Fika no 2: Can Sweden achieve negative C02- emissions?

Research profile seminar

Warmly welcome to Researchers Fika, a new activity for the Research Network for Sustainable Development at Chalmers and the University of Gothenburg. At each fika you will get to listen to speed talks on a sustainability-oriented topic from researchers representing different disciplines followed by an opportunity to network and digitally share your favorite fika with the other participants in the meeting.

Talks

Why Sweden has a unique position to lead the path to the 1.5-degree climate target
Anders Lyngfelt, Professor at the Department of Space, Earth and Environment, Chalmers University of Technology

To succeed to keep global warming below 1,5 degrees we must keep our emissions within the so-called carbon dioxide budget. With today's emission level this budget is exhausted already in 2028 according to the 1.5-degree report from IPCC. Meeting the budget does not only require a rapid reduction of emissions, we must also realize large negative emissions of CO2. Sweden is in a unique position with great unused potential for negative emissions from existing large point sources, as well as being close to geological formations in the North Sea well suited for safe storage. This talk will give a brief introduction to negative emissions and discuss technologies available, costs, and potential financing of negative emissions.

Greenhouse gas emissions from forest land and possibilities to gain negative emissions
Åsa Kasimir, Researcher at the Department of Earth Sciences, University of Gothenburg

Globally land use is a source of greenhouse gases (GHG's), where agriculture and forestry together contribute 23% of the total emissions. However, in Sweden the national reporting on GHG's shows the forest sector to be a net sink of C02 emissions. Included in this sink are forest on drained peat soils in Sweden, which are a source of GHG. All emissions needs to be mitigated, where drained peat soil could be a fairly easy target. With a water table just below the soil surface and a changed vegetation, which can cope wet conditions, it is possible to minimize emissions and regain an uptake, i.e. negative emission. In this talk Åsa will talk more about her research to measure emissions from different drained peat ecosystems and restored mires.

The role and opportunties for BioCCS in combating climate change
Fabian Levihn, PhD and head of Research & Development at Storckholm Exergi AB

In this talk Fabian will explain how negative emissions increase the economic efficiency of reaching the Paris agreement goals of limiting climate change.
