According to the IPCC, we are in the critical decade in the fight against climate change. To achieve a 1.5°C outcome, global GHG emissions need to reduce by 45% by 2030 and net zero by 2050.1 In response, many investors have adopted climate action plans. A feature of many such plans is to reduce their portfolio’s emissions footprint (i.e. their proportionate ‘ownership’ of the underlying companies’ emissions) in line with similar 2030 and 2050 goals.
