CO2-emissions from Norwegian oil and gas extraction

Emissions from oil and gas extraction matter for the life cycle emissions of fossil fuels, and account for significant shares of domestic emissions in many fossil fuel exporting countries. In this study we investigate empirically the driving forces behind CO2-emission intensities of Norwegian oil and gas extraction, using field-specific data that cover all Norwegian oil and gas activity. We find that emissions per unit extraction increase significantly as a field's extraction declines. Moreover, emission intensities increase significantly with a field's share of oil in total oil and gas reserves. We also find some indication that oil and CO2-prices may have influenced emission intensities on the Norwegian continental shelf. (C) 2015 Elsevier Ltd. All rights reserved.
