Question from UPSC Prelims 2020 GS Paper

Explanation:

Social Cost of Carbon

Social Cost of Carbon (SCC) is a concept used by economists and policymakers to quantify and monetize the long-term economic damages associated with an incremental increase in carbon dioxide emissions in a given year. This includes a wide range of impacts, such as changes in net agricultural productivity, human health, property damages from increased flood risk, and changes in energy system costs, among others. The SCC is used to estimate the value of damages avoided for a small emission reduction (or conversely, the damages incurred by an additional ton of carbon emissions). It provides a way to evaluate the economic benefits of policies that reduce greenhouse gas emissions by comparing them to the policy costs. Therefore, it plays a crucial role in the development of climate policy and environmental regulation by helping to inform cost-benefit analyses of climate actions.
