Abstract: Building on updated estimates of the social cost of carbon obtained from the most recent literature, this article proposes a social cost of carbon-based benchmark for carbon pricing to drive world countries’ carbon pricing policies up to 2050, consistent with the Paris Agreement targets. By using a dataset on net effective carbon rates developed by the Organisation for Economic Co-operation and Development (OECD), we firstly compare both explicit and implicit carbon pricing in 2021 in 71 OECD and non-OECD countries with the social cost of carbon benchmark for 2021 and calculate the degree of internalization of the social cost of carbon averagely related to their carbon pricing instruments. We find that there is a serious gap in current climate policies, which are far from creating optimal pricing conditions to reduce global emissions to levels needed by the Paris Agreement. The economic and distributional feasibility of a full implementation of the carbon pricing benchmark is tested in the same set of countries using two indicators, which are calculated for 2025, 2030, 2040 and 2050. Since the test results are income-regressive among income country groups, benchmark implementation by countries within the cooperative approaches of Paris Agreement art. 6 should be accompanied by the creation of an international cooperative fund aimed to recycle at least part of the revenues collected by high-income countries to compensate affected population in lower-income countries.
