India, the world's third biggest emitter of greenhouse gases, has set a 2070 goal for net zero carbon emissions.

Prime Minister Narendra Modi is targeting raising the share of natural gas in India's energy mix to 15% by 2030 from the current 6.2%. Natural gas, while still a fossil fuel, emits less CO2 than coal.

The Petroleum and Natural Gas Regulatory Board on Friday set a deadline of April 6 to submit bids for city gas distribution (CGD) authorisation for areas offered in the states of Bihar, Jharkhand, West Bengal, Uttar Pradesh and Chhattisgarh.

The board has so far awarded CGD licences for some areas of 27 states and union territories covering 70% of India's population, and is in the process of finalising winners for its previous round, in which 26 entities had submitted bids for 61 geographical areas.

After bids in the latest rounds are finalised, about 88% of the country's area will be authorized for the development of the CGD Network, providing access to natural gas to about 98% of India's population, the board said in the statement.
