India should enhance its actions in three areas, renewable energy, mobility and transforming the agricultural sector, the Executive Director of the United Nations Environment Programme (UNEP) said.
Solheim is in India for a week.
He stressed that India needs to "move fast" to tackle the issue of air pollution.
"China and India are both countries with ambitious visions on environment. Yes, in recent years, China has moved quickly on air pollution, and I see India moving in that direction as well.

Terming India's efforts to fight air pollution in New Delhi and other big cities as "very encouraging", he had earlier said that the country's experience in harmonising development and environment protection is an example for the world.
The air pollution in northern India, especially in Delhi-NCR, had reached alarming levels and even "emergency" levels last year.
A report released by a green body in early 2017 had said that Delhi tops the list of 20 most polluted cities in the country where 1.2 million deaths take place every year due to air pollution.
Solheim said that India has more benefits in comparison to China, and the country under Prime Minister Narendra Modi has a "very clear" direction towards tackling the issue which is very "positive".
Speaking on the sectors which India needs to focus on, the UNEP chief said that focus on energy should be the number one priority to "spur solar and green revolution".
In 2002, China introduced two metro systems and now has the biggest metro networks in the world, Solheim said.
He pointed out that there has been a "sea change" as far India's approach at climate negotiations are concerned.
"I think there is a sea change. Ten years back India was so defensive in negotiations. Now India is taking a much more 'front seat role' and much more positive looking," the UN official said.
India will be the global host of the World Environment Day and the "Beat Plastic Pollution" theme.
