16. Microbial mitigation of greenhouse gas emissions from boreal lakes
Sammanfattning : The climate change crisis has drawn the attention of both the public and scientific community to the carbon cycle and particularly to the importance of greenhouse gases (GHG) carbon dioxide (CO2) and methane (CH4). CO2 has been a key component of Earth´s climate regulation throughout its geological history and is now the main driver of the current change in climate. LÄS MER
17. Essays on Policies to Reduce Agricultural Greenhouse Gas Emissions

18. Towards a changed view on greenhouse gas exchange in the Arctic: new findings and improved techniques
Sammanfattning : Arctic ecosystems represent an important component in the global terrestrial exchange of greenhouse gases and energy with the atmosphere. In the changing climate, which is most pronounced in the Arctic, the possible scenarios of greenhouse gas exchange response should be seriously considered in predictive climate modelling efforts.

19. Land-use competition and agricultural greenhouse gas emissions in a climate change mitigation perspective
Sammanfattning : Productive land for food production, bioenergy, or preservation of nature is a limited resource. Climate change mitigation puts additional pressure on land via higher demand for bioenergy to replace fossil fuels and via restrictions on deforestation—two processes that limit the availability of land for food produc- tion, and may thus also raise food prices.

20. Reducing ships' fuel consumption and emissions by learning from data
Sammanfattning : In the context of reducing both greenhouse gases and hazardous emissions, the shipping sector faces a major challenge as it is currently responsible for 11% of the transport sector’s anthropogenic greenhouse gas emissions. Even as emissions reductions are needed, the demand for the transport sector rises exponentially every year. LÄS MER
