Mumbai Airport recognized for environmental achievement
The Airports Council International (ACI) has certified Mumbai Airport with the highest level of environmental achievement, Level 3+ Carbon Neutrality. Airports receive accreditation in recognition for contributions to greenhouse gas management by offsetting and reducing carbon emissions.
How accreditation was earned
The airport has measured and improved sustainability through several initiatives.
- Indian Green Building Council (IGBC) awarded Terminal 2 LEED Gold in 2014. By 2016, additional initiatives resulted in award of LEED Platinum.
- Maximum use of natural light
- Central lobbies have heat reflector ceilings and walls that use maximum light while inhibiting heat.
LED lighting for buildings and runways
- Conversion to LED lighting has reduced the airport’s grid load by 700kw.
- 9000 bulbs have been upgraded with LED bulbs.
- The runway is lit entirely with LED high-mast lighting.
Solar panels have been installed on older terminal buildings. These generate 2.56 MW solar energy, which reduces carbon emissions by about 1,220 tons each year.
Solid Waste Management
An organic waste converter installed at the airport now converts food into organic fertilizer. The composted waste has been diverted from landfills to instead nourish plants at the airport.
Airport horticulture further benefits from wastewater. An on-site water treatment facility recycles wastewater for use in indoor and outdoor plantings, HVAC systems, and other systems not needing potable water.
Managing carbon emissions
Mumbai Airport participates in the ACI’s Airport Carbon Accreditation program. They set a baseline year of 2014. Their goal for 2020 is 25% reduction in carbon emissions from direct fuel consumption and indirect energy purchase.</p?
The goals and achievements at Mumbai Airport are further distinguished by its size and activity. More than 45.5 million passengers traveled through it in 2016 and 2017.
