First of all, we need a better business case for green investments. One policy instrument is absolutely key here, and that is to raise the effective price of greenhouse gas emissions. Carbon emissions are the main, but not the only contributor to greenhouse gases. You see, I’m an economist.
Some may call it naïve, but I have this firm belief, backed by experience, that for economic transformation to take hold, you need to have relative prices that reflect the true scarcity of economic resources. In this case, by pricing in the climate cost of greenhouse gas emissions. Internalizing the externality.
