Mains Paper 3: Environment | Conservation, environmental pollution and degradation, environmental impact assessment
From UPSC perspective, the following things are important:
Prelims level: Global Carbon Project
Mains level: Trends in global carbon emission
Coal use hampers
- This week, representatives from more than 190 countries have begun discussions at the UN Climate Change Conference (COP 24) in Katowice, Poland, on ways to equitably cut carbon emissions.
- However global carbon emissions are set to hit an all-time high of 37.1 billion tonnes of CO2 in 2018, according to researchers at the University of East Anglia (UEA) and the Global Carbon Project.
- India, the third-highest contributor, is projected to see emissions rise by 6.3% from 2017.
- The 2.7% projected global rise in 2018 has been driven by appreciable growth in coal use for the second year in a row, and sustained growth in oil and gas use.
- Though coal use contributed to the rise in 2018 from last year, it still remains below its historical high in 2013 but may exceed that if current growth continues.
China and US rocks global emission
- The 10 biggest emitters in 2018 are China, US, India, Russia, Japan, Germany, Iran, Saudi Arabia, South Korea, and Canada.
- The EU as a region of countries ranks third.
- China’s emissions accounted for 27% of the global total, having grown an estimated 4.7% in 2018 and reaching a new all-time high.
- Emissions in the US, which has withdrawn from its commitment to the Paris Agreement, account for 15% of the global total, and look set to have grown about 2.5% in 2018 after several years of decline.
About Global Carbon Project
- The Global Carbon Project (GCP) established in 2001 is the organisation that seeks to quantify global carbon emissions and their causes.
- The main object of the group has been to fully understand the carbon cycle.
- The project has brought together emissions experts and economists to tackle the problem of rising concentrations of greenhouse gases.
- It releases the Global Carbon Atlas, a tool for the visualization of data related to the global carbon cycle.
