Phase IFoundation

Background

Overview

UPSC frequently examines the evolution, effectiveness, challenges, and India's stance on international climate agreements, their impact on national policy, and the global efforts to combat climate change, with a growing focus on implementation challenges.

International Climate Regimes refer to the global legal and policy frameworks established under the United Nations to address climate change, primarily through the United Nations Framework Convention on Climate Change (UNFCCC). These regimes aim to stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.
