This post examines key aspects of climate mitigation policies that could matter for monetary policy, using insights from structural climate macroeconomic models (Environmental Dynamic Stochastic General Equilibrium). Three main findings emerge: first, mitigation policies – like carbon pricing – can be a direct source of shocks, creating potential trade-offs for monetary policy (Carney (2017)). Second, the degree to which these policies are anticipated affects their macroeconomic impacts. Third, different climate policies may alter the transmission of conventional business-cycle socks, therefore affecting the calibration of optimal monetary policy. We focus on the 3–5 year horizon, abstracting from longer-run considerations and changing trends such as interactions with the zero lower bound, the natural interest rate, or transitional effects on productivity and output.
