Carbon dioxide Current Affairs - 2020
The International Energy Agency (IEA) report on Carbon dioxide emissions makes the following observations:
- India emitted 2,299 million tonnes of carbon dioxide in 2018. India’s emissions carbon dioxide witnessed an increase of 4.8% rise from last year.
- The rate of growth of carbon dioxide emission in India was higher than that of the United States and China which are the two biggest emitters in the world. This increase in the emission of carbon dioxide was attributed to coal consumption.
- China, the United States, and India accounted for nearly 70% of the rise in energy demand.
- India’s per capita emissions were about 40% of the global average and contributed 7% to the global carbon dioxide burden whereas the largest emitter the United States was responsible for 14%.
- Under the INDC India has pledged to reduce the emissions intensity of its economy by 2030. But India’s energy intensity improvement declined 3% from last year even as its renewable energy installations increased 10.6% from last year.
As per estimates, India requires at least $2.5 trillion (Rs 150 trillion approx.) to implement its climate pledge which is around 71% of the combined required spending for all developing countries pledges.

The world’s first negative emissions plant under the CarbFix Project to turn atmospheric carbon dioxide (CO2) into stone has begun operations in Hellisheidi, Iceland. It is intended to lock away carbon dioxide by reacting it with basaltic rocks. Work on the project began in 2007.
In it, the CO2 is captured from ambient air, bound to water, and sent to more than 700 meters underground. There, the CO2 reacts with the basaltic bedrock using enhanced weathering process and forms solid minerals, creating a permanent storage solution.
Currently, the system captures only 50 metric tons CO2, each year, about same emitted by a single US household. It can remove an estimated 50 metric tons of CO2 from the air in a year. It pumps the collected gas deep into the island’s volcanic bedrock, where it reacts with basalt and essentially turns into limestone.
