India plans to replace its railway system operated by Indian railways with "green railways" and achieve net-zero carbon emissions by 2030. The measures include:
- electrification of the railways;
- improving energy efficiency of locomotives, trains, and fixed installations;
- acquiring green certification for stations/installations;
- switching to renewable sources of energy.
As of 2021, Indian Railways installed 111 MW of rooftop solar power capacity on various stations and administrative buildings, 6.7 MW of ground-mounted solar and 103 MW of wind energy. Additional 3,450 MW of solar and wind capacity are under development. As of January 2021, a total of 42,354 kilometres of railways have been electrified, and all routes on the Broad Gauge network are planned to be electrified by December 2023.
