India faces several environmental challenges in achieving its target of becoming a global leader. Some of these challenges include:

• Air pollution: India's major cities suffer from high levels of air pollution, mainly due to vehicular emissions, industrial pollution, and construction activities. The government has taken measures such as the implementation of the National Clean Air Program and the introduction of the BS-VI emission norms to combat air pollution.
• Water pollution: Rivers and lakes in India are polluted due to untreated sewage, industrial waste, and agricultural run-offs. The government has launched initiatives such as the Namami Gange project and the Swachh Bharat Abhiyan to tackle water pollution.
• Climate change: India is vulnerable to climate change impacts such as extreme weather events, sea-level rise, and glacier melting. The government has undertaken various measures such as the National Action Plan on Climate Change and the International Solar Alliance to address climate change challenges.
• Biodiversity loss: India is home to diverse flora and fauna, but the habitat loss due to deforestation, poaching, and encroachment poses a threat to biodiversity. The government has launched initiatives such as Project Tiger and the National Biodiversity Act to protect biodiversity.
• Waste management: India generates a vast amount of solid waste, and improper disposal leads to land pollution and health hazards. The government has launched initiatives such as the Swachh Bharat Abhiyan and the Waste Management Rules to address waste management challenges.

Despite the challenges, the Indian government has taken significant steps to combat environmental issues and achieve its target of becoming a global leader.
