The carbon emissions targets set by the Paris Agreement look set to have far reaching implications for long term corporate strategies. As the oil and gas industry is a large energy intensive sector of the global economy we expect investors and other stakeholders to increase scrutiny on corporate carbon footprints and value at risk. The agreement has the potential to have a material impact on corporate asset valuations. However with no standardised reporting methodology agreed the availability of asset level carbon emissions data is limited to a subset of established petroleum provinces including Canada the UK and Norway. By combining emissions data from the Norwegian Environment Agency and our own production and reserves data we can conduct a more comprehensive assessment of the variation of intensity across field life.
