Long-term changes in temperature and weather patterns are referred to as climate change. These changes could be caused by natural processes, such oscillations in the solar cycle. But since the 1800s, human activities primarily the combustion of fossil fuels like coal, oil, and gas have been the primary cause of climate change. Fossil fuel combustion produces greenhouse gas emissions that serve as a blanket around the planet, trapping heat from the sun and increasing temperatures. As emissions climb, greenhouse gas concentrations are at their greatest points in two million years. The finding is that the Earth has warmed by around 1.1°C since the late 1800s. The most recent ten years (2011–2020) were the warmest ever. India has made a commitment to cut its GDP's emission intensity by 45 percent by 2030. According to Climate Action Tracker (CAT), which is an independent scientific study provided by two research organizations monitoring climate action since 2009, this research paper will assess India's pledge in Conference of Parties (COP 26 & COP 27) and performance as per its commitment.
