Delhi’s Indira Gandhi International Airport (IGIA), managed by GMR led consortium, Delhi International Airport (P) Limited (DIAL), has become Asia-Pacific’s first airport to achieve Carbon Neutral status.
The globally reputed Airports Council International (ACI) announced this during the Airport Carbon Accreditation certificate presentation ceremony in Montreal, Canada, on September 27, 2016. It has upgraded Delhi Airport to "Level 3+, Neutrality", which is the highest level of achievement available to airports across the world. The Airport Carbon Accreditation monitors the efforts of airports to manage and reduce their carbon emissions.
With this exemplary achievement, DIAL has delivered on its commitment of achieving sustainable solutions for Aviation Climate Change mitigations made at LPAA-COP 21 in 2015 through carbon neutrality.
ACI is the same body that had awarded Delhi Airport the world’s number one position (in 25-40 million passengers per annum category) twice in a row under the Airport Service Quality (ASQ) programme.
Carbon neutrality occurs when the net carbon emissions over an entire year is zero. This means the airport absorbs or offsets the same amount of emission that was generated. This achievement is accredited by ACI under Airport Carbon Accreditation that monitors the efforts of airports to manage and reduce their carbon emissions.
At IGIA, DIAL has taken the proactive approach towards environment management and sustainability development. Terminal 3 of Delhi Airport is a LEED Gold certified green building. The energy efficiency measures implemented in IGIA has been registered in UNFCCC as Clean Development Mechanism project. DIAL has also set up 7.84 MW solar power plants to reduce GHG emission.
Other energy efficient and environment friendly infrastructures at the airport include state of the art Sewage Treatment Plant (STP) and Water treatment plant (WTP), energy efficient Bridge Mounted Equipment (BMEs), energy efficient lighting systems, advanced fuel hydrant systems, Fixed Electric Ground Power Units (FEGP) and Preconditioned Air (PCA) supply systems. The various emission saving measures implemented in DIAL have resulted in 51% reduction in specific GHG emission (kgCO2/Pax) during the last five years.
IGIA is the first Airport in the world to be certified for ISO 50001:2011. This airport is also certified for Environment Management System (ISO 14001:2004). Delhi Airport has won numerous awards and recognitions including Green Company - Gold Rating Award and National Award for Excellence in Energy management – 2015 by CII--Green Business Center, Golden Peacock Environment Management Award and Golden Peacock Sustainability Award – 2015 by Institute of Directors for its exemplary performance towards environmental sustainability initiatives.
