This IMF working paper provides a quantitative framework for understanding the main impacts of emission pricing, trade-offs between pricing and other (commonly used) mitigation instruments, and to what extent policies need to differ across countries in G20 countries. The results underscore the generally strong case for (comprehensive) pricing over other instruments, its small net costs or often net benefits, but also the potentially wide dispersion (and hence inefficiency) in emissions prices implied by countries’ mitigation commitments. The full paper is available on the IMF website.
