Climate change, in my view, is likely to be one of the foremost macroeconomic, financial, and debt policy challenges that IMF members will face over the coming decades. Meeting this challenge will require an unprecedented and massive scaling up of global investments for climate adaptation and mitigation. The good news is that at the current rate of $630 billion a year, the scaling up has already begun. ESG investments continue growing as an asset class on the investment landscape. The bad news is that this amount is still far short of the estimated financing needed for the green transition.
