Climate Policy and Initiatives

Despite committing to net-zero emissions by 2050 and the goals of the Paris Agreement, SMBC Group has failed to align its new policies with these goals.  Its latest climate policy update lacks concrete action plans. SMBC has not yet disclosed meaningful short- and medium-term targets for emissions reduction nor have they revealed any meaningful measures taken to ensure that the bank is not financing fossil fuel supply expansion or its associated infrastructure, in line with the IEA's Net Zero Roadmap.
