While sustainable investing is no longer a novelty, investment strategies that take an integrated gender and climate lens to investment decisions are still relatively new. Investment in climate action exceeded $500 billion in both 2017 and 2018, while in 2020 (the year before this resource was published) green bonds and green debt instruments crossed the cumulative $1 trillion mark. The field was helped by short term impacts synching well with funding cycles and being easier to measure than the typically longer-term impacts of gender-positive investing. Indeed, Gender lens investing as a phrase is only just over a decade old and the resulting lack of longitudinal data reduces the ability to perform predictive modelling in gender-lens investment. The two investment areas - climate and gender - have therefore tended to operate, as a result, in silos, but integration of the two can unlock huge untapped opportunities.
