What does "greening” of money creation mean?

Central banks in OECD countries are monetising the fiscal deficits run up by governments in response to the coronavirus crisis. We often hear calls for this money creation to be "green", i.e. to finance climate and environmentally useful spending. But it is important to understand that this "greening ” of money creation is not a monetary policy problem, and is not the responsibility of central banks. Governments are increasing public spending and cutting taxes in reaction to the crisis , and the corresponding fiscal deficits are being monetised by central banks. What matters is therefore the nature of the new government spending and the tax cuts: do they promote energy transition and respect for the environment? It is therefore clearly governments’ fiscal policy choices that are important. Moreover, this is normal in a democracy: it is not up to the central bank to choose the nature of government spending.
