As per latest Forest Survey of India report 2011, Green cover of Delhi has increased to about 296.20 sq km in 2009 from 26 Sq. Km in 1997. After having achieved unprecedented success in increasing the green cover, efforts have been sustained to plant more and more trees on vacant lands through active involvement of greening agencies and community participation. This also includes free distribution of saplings to schools, RWAs, NGOs and other citizen groups through Forest Department’s nurseries, petrol pumps, CNG Stations, mother dairy booths etc and financial assistance to RWAs for maintenance of parks and gardens.



In 2009, Delhi received INDIRA PRIYADARSHINI VRIKSHA MITRA AWARDS from Ministry of Environment and Forest, Govt. of India for increasing and maintaining the green cover in Delhi.



Today, Delhi has nearly 20000 small/medium/big parks and gardens, 40 city forests, 5 ridge areas, 2 bio-diversity parks and other green belts.


Under City Plants a Million Tree Campaign, 2011 conducted during monsoon,a total of 14.5 lakh saplings have been planted by various departments / agencies / organizations. This year also similar campaign during monsoon will be conducted.

The Forest department is striving to increase the forest and tree cover in Delhi to 310 by the end of 2012

Parks and gardens in Delhi are being maintained and developed through Delhi Parks and Garden Society (DPGS), an autonomous body under Department of Environment, which also provide financial assistance to RWAs / NGOs for maintaining parks / gardens. So far, 1205 parks are being maintained by 253 RWAs through Grant-in Aid from DPGS, which amounts to Rs. 3.34 Crores.
Made mandatory for plots having minimum area of 100 sq. meters to install the Rainwater Harvesting Structures in their premises.
The financial assistance for 50% of the project cost or Rs. One Lakh, whichever is maximum, is provided by Delhi Govt/DJB to the RWAs/Schools for this purpose.
Rain water harvesting structures have been created in more than 100 schools and colleges to harvest the 40 hours of rain in Delhi
Rain water harvesting structure will be installed in 2500 schools and colleges.
Waste Paper Recycling machine has been setup in the Delhi Secretariat for recycling the waste paper.
88 paper recycling machines installed in schools of Delhi so far and 100 more being installed this year.
Cost of Paper Recycling Unit is about Rs.1.0 lakh
Delhi Govt. has made the use of solar water heating system mandatory in the buildings like Industries, Hospitals, Nursing homes, Hotels, Canteen, Residential buildings having an area of 500 sq.m, and above educational colleges, hostels, technical or vocational colleges etc.
Govt. of Delhi is providing rebate/ incentive of Rs. 6000/- to domestic consumers and upto Rs. 60000/- @ Rs. 6000/- per 100 LPD to Non-Comercial Institutes.
45 solar water heater installed in schools & colleges of Delhi so far and 50 more being installed this year.
Cost for 1000 liter of solar water heater is about Rs.1.2 to 1.4 lakh
  Savings are 50 – 85% annually on power bills.


High performance Green Building design relies on renewable sources for energy systems; recycling and reuse of water and materials; integration of native and adapted species for landscaping; passive heating, cooling and ventilation; and other approaches that minimize environmental impact and resource consumption.



Delhi Government has brought out an Action Plan for Implementing the Climate Change Agenda 2009-2012, wherein it has identified one of the point for implementation is as follows:

“To reduce the energy consumption in existing buildings by 30-40% in relation to the conventional buildings. Make at least 250 Green Buildings by adopting the Green Buildings Standards and 50% buildings be retrofitted for this and another 50 % new buildings to be made.”



The Government of NCT of Delhi has been promoting these measures over a period of time. In this context, some of the issues relating to above have already been addressed. Site selection and orientation of building, Rain Water Harvesting both roof top and storm water management, use of LED lights (Light Emitting diodes), self reliant energy productions (Gas base turbines has been installed in Thyagraja Stadium for generation of electricity), replacement of CFCs (Chloro Fluoro Carbons) refrigerants by HFCs (Hydro Fluoro Carbons) refrigerants, use of solar energy and use of energy efficient chillers in air conditioning systems, etc. are to name a few.



The Energy Conservation Building Code (ECBC) was launched by Bureau of Energy Efficiency in 2007 with the goal of specifying standards for new, large and energy efficient commercial buildings. The ECBC sets minimum energy performance standards for commercial buildings. ECBC provides guidelines and norms for the energy-efficient design and construction of buildings, reduced energy requirement, enhanced residents’ comforts and environmentally benign design techniques.



The Government of Delhi has made mandatory implementation of Energy Conservation Building Code (ECBC) in Government Building/ Building complexes (new construction) including building/building complex of municipalities/ local bodies, Boards, Corporations, Government aided institutions and other Autonomous Bodies of the Government of NCT of Delhi.



To establish a baseline for construction of green building from concept to completion, the Government of Delhi adopted GRIHA (Green Rating for Integrated Habitat Assessment) ratings in conjunction with ECBC norms and NBC code, for developing three star rating Green Building. GRIHA was conceived by TERI and developed jointly with the Ministry of New and Renewable Energy, Government of India. It is a green building 'design evaluation system', and is suitable for all kinds of buildings in different climatic zones of the country.



Energy Auditing has been in Government buildings in Delhi. Also, the energy efficiency of existing government buildings are being upgraded through retrofitting.
