The government has told the court that around five lakh seedlings have been planted in order to compensate for the 46,529 trees that have been felled by Delhi Metro from 2003-04 to 2014-15.

The Aam Aadmi Party government has told the court that about “20 greening agencies”, including the horticulture wings of various municipal bodies, as well as its forest department are carrying out plantation activity with a target of improving air quality and reducing pollution in the city.

Earlier, it used to insist on planting of 10 saplings for every tree cut, but the policy was “refined” in 2010 to ensure plantation of at least five saplings, as planting of 10 by the user agency was “not encouraging” and most were almost “failures”, the AAP government told the court.

The submissions have been made in an affidavit filed in the high court on a PIL over the issue of rise in air pollution in the national capital.

On the National Forest Policy of 1988 envisaging an average national forest cover of 33 per cent, the court was told that Delhi being an urban capital with ever-expanding developmental needs for its rising populace, there would always be a crunch for land for planting trees.

The affidavit said, the government was leaving no stone unturned to increase green cover in Delhi and its efforts are leading to a gradual rise in number of trees.

It also mentioned that the Metro has also paid Rs 71.67 crore towards the compensatory plantation. The government has also told the court that earlier it used to charge Rs 28,000 per felled tree from individuals or for commercial projects to plant 10 trees under compensatory plantation.
