Using the Carbon Impact Analytics (CIA) methodology, Carbon4 Finance established a ranking of companies within the O&G industry depending on their level of exposure to transition risks. Based on our data and analysis, we observed historical trends in GHG absolute emissions (Scope 1, 2 & 3) and appreciated the strategies implemented to align – or not – with decarbonation objectives for the world economy. This briefing note summarizes the results of the CIA (Carbon Impact Analytics) campaign led between June and September 2020 on a sample of a hundred companies of the Oil & Gas (O&G) industry. The CIA methodology aims at measuring stakeholders’ exposure to transition risks with a rating scheme (from A+ to E-) and sector-specific KPIs. et différents indicateurs sectoriels.
