The table below shows, from highest to lowest, the top 10 companies which have seen the largest year on year increase of CO2 emissions.

• This is based on companies which disclose their emissions - there may a number of companies which are still not yet disclosing their emissions at all, or are only disclosing scope 1 of their emissions (those which they are directly responsible for). As such, there may be other companies which have seen larger YoY emission changes than this list of 10, which are not currently being captured.
• Bouncing back from Covid-19 is likely to impact sectors differently, with some sectors seeing a larger change in emissions than others due to the nature of their business activity. Therefore in normal times, these top 10 worst companies may not have seen such large increases in their emissions.
