Here are some major steps taken by the Indian government to address the issue of climate change:

• The Indian government has set a target to achieve 175 GW of renewable energy capacity by 2022, including 100 GW of solar power.
• The government has launched several initiatives such as the National Solar Mission, the UJALA scheme for energy-efficient LED lighting, and the Smart Cities Mission to promote sustainable development.
• India has pledged to reduce its emission intensity by 33-35% from its 2005 levels by 2030 under the Paris Agreement.
• The government has launched the National Adaptation Fund for Climate Change to provide financial support to vulnerable communities and states to adapt to the impacts of climate change.
• India has also launched the International Solar Alliance to promote the use of solar energy around the world.
• The government is promoting electric mobility through initiatives such as FAME India (Faster Adoption and Manufacturing of Electric Vehicles in India), which provides subsidies for buying electric vehicles.

These steps demonstrate India's commitment to combating climate change and promoting sustainable development. However, there is still much more work to be done to address this global challenge.
