The Indian government has taken several steps to address environmental sustainability issues.

• One of the key measures has been the promotion of sustainable agriculture, which includes the use of natural fertilizers, conservation of water resources, and adoption of organic farming methods.
• The government has also set up several initiatives to reduce carbon emissions, such as the National Solar Mission, which aims to achieve 100 GW of solar energy capacity by 2022.
• The government has launched the Swachh Bharat Abhiyan, a nation-wide campaign to improve hygiene and sanitation practices, which indirectly helps reduce pollution levels.
• Various policies such as the National Action Plan on Climate Change, National Green Tribunal, and the Forest Conservation Act have been introduced to protect the environment and promote sustainable development.
• Additionally, the government has adopted a number of measures to address air pollution in cities, including the implementation of Bharat Stage VI emission norms and the introduction of electric vehicles.

Overall, these initiatives reflect the Indian government's commitment to achieving environmental sustainability and mitigating the impact of climate change.
