New Delhi: Urging developed countries to do more to combat climate change, environment minister Prakash Javadekar on Tuesday said that the aim of mobilizing $100 billion a year for developing nations has remained at the stage of discussions, with no concrete action plan laid out as yet.

“India has levied a clean environment cess of $6 ( 400) per tonne on coal. If the developed world follows India in taxing its coal production, $100 billion can be raised," Javadekar suggested on the eve of his departure to New York for signing the Paris Agreement.

The Paris climate accord, which was agreed to by over 190 countries in December 2015, commits developed countries to provide finance to the tune of $100 billion a year by 2020 to developing nations.

Over 150 countries are expected to be represented in New York for the signing of the Paris Agreement on Climate Change.

“The developed world must provide technological support to the developing nations in the fight against climate change," added Javadekar.

The environment minister, who led India at the Paris climate summit, said that India was leading by example on mitigation and adaptation, citing the target of generating 175 gigawatts of renewable power by 2022.

Javadekar also mentioned steps taken by the government to move towards a cleaner fuel regime, such as moving to Bharat Stage VI (BS-VI) norms from BS-IV by 1 April 2020, thereby skipping BS-V altogether.

“The government has taken a decision to promote blending of ethanol with petrol and its use as an alternative fuel and has also taken a decision to tax SUVs (sports utility vehicles) and diesel vehicles. 93 million LED bulbs have been distributed till 12 April 2016, which has resulted in energy savings of more than 33.3 million kWh every day," he added.

The Paris Agreement will be implemented from 2020. As per its clauses, developed countries will have to provide finance of $100 billion a year by 2020 to developing countries, but this pledge is ambiguous and lacks a clear road map. The agreement also provides for setting a new collective quantified goal over a floor of $100 billion per year from 2025 onwards.
