Escalating global warming is threatening the very existence of life on our planet and must be contained. The 2015 Paris Agreement sets an absolute upper limit of 2°C on increase in global mean temperature by the end of this century. It also calls for ample efforts to limit the warming to a less risky 1.5°C.

A 2018 IPCC report titled Global warming of 1.5°C has estimated the amount of CO2 the world can emit to stay below 1.5°C global warming over pre-industrial levels. The world had already emitted about 2,200 Gt of CO2 from the dawn of the industrial revolution till 2017.

The world emitted 37 Gt of CO2 in 2018. If we include other greenhouse gases (GHGs) such as methane, it emitted more than 53 Gt of carbon dioxide equivalent (CO2e) in the same year.

Carbon markets are dealt with under Article 6 of the Paris Agreement. Two important parts of Article 6 are: o Article 6.2—Internationally Transferred Mitigation Outcomes o Article 6.4—Sustainable Development Mechanism.

The world is facing an existential threat. But it is also clear that without equity, ambition is not possible. The ongoing CoP25 must not duck this question any further says Centre for Science and Environment in its new position paper "COP 25: What the world must do"

Solar-powered irrigation is being aggressively promoted by the government as an affordable and sustainable solution for agriculture as well as the rising burden of electricity subsidy. But will solar pumps become a win-win situation for all stakeholders?

India will leapfrog to BS VI emissions standards in 2020 to cut emissions by 80-90 per cent from new vehicles.
