Want to know how Sumday thinks about the future of financed emissions?
"Investors want to unlock sustainable investment and account for impact, without an accusation of greenwashing. However, the current approach to calculating financed emissions is grossly inadequate for banks and investors to make informed decisions. They cannot truly track their progress towards net zero or offer sustainability linked finance with confidence that targets have been met by customers and portfolio companies."

A few myths worth busting
The ISSB standards state that financial institutions will need to account for scope 3 emissions in line with the GHG Protocol from 2025, these are their words: IFSR 2, section B59 Paragraph 29 (a)(i)(3) requires an entity to disclose its absolute gross Scope 3 Greenhouse gas emissions generated during the reporting period, including upstream and downstream emissions. An entity that participates in one or more of the following financial activities is required to disclose additional and specific information about its Category 15 emissions or those emissions associated with its investments which is also known as ‘financed emissions’: (a) asset management (see paragraph B61); (b) commercial banking (see paragraph B62); and(c) insurance (see paragraph B63).
For banks and investors, the majority of emissions come from the companies you lend to or invest in. Without actual data from those companies, it is impossible to accurately account for emissions. Failing to account for these emissions often means reporting on less than 10% of the actual carbon footprint, which needs to be clearly disclosed. While asking companies to report their carbon emissions was once a unique request, it has become increasingly common worldwide. It’s irrelevant as to whether those companies have a legal obligation to provide the data, you can still ask and offer support. With Sumday, you can add value by supporting your customers and portfolio companies to start carbon accounting, benefiting both them and your institution.
