Accordingly, as of 2019, BNP Paribas uses the me- thodology developed, on a sector-by-sector basis, by the think tank '2 Degrees Investing Initiative', to calculate the loan book's profile at various maturity dates for five high-carbon sectors (extraction of fossil fuels, electricity generation, transport, steel produc- tion and cement production). The method, tailored to each sector, employs benchmark scenarios used and developed by independent organisations such as the International Energy Agency (IEA). For electricity ge- neration, extraction of fossil fuels and the automotive sector, the approach is based on the energy mix33 or technology mix. For aviation, maritime transport, cement and steel, carbon emissions intensities are analysed.
