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.
