Abstract [sv]

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?

The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil. The mitigation options are discussed from two different theoretical perspectives. The principle of the theory of ecological modernisation is that innovation and environmentally friendly technology can solve the environmental problems human societies face today, whereas the theory of common pool resources promotes local communities to govern limited resources in order to manage them sustainably.

The findings suggest that ecological modernisation legitimize environmental destruction as carbon dioxide storage in geological formations (CCS) use the technology as a mean to extract more oil and gas; which results in a rebound-effect. Therefore, carbon dioxide capture in geological formations is not a realistic method unless it can prevent further emissions. Protected forest resources can be seen as biological insurance, which safeguard ecosystem services, biodiversity, and the forest potential to hold carbon. Carbon sequestration in tropical forest has the potential to store carbon dioxide given that the forests are protected and local communities have tenure rights, knowledge, and the means to protect the forest and manage them sustainably.
