Stansted airport has been awarded the Carbon Trust Standard for reducing its building and on-site vehicle-based emissions by 2% from 2007 to 2009.
The emissions cuts have been achieved through efficiency measures, new technology and behavioural change initiatives.
For example, the airport has installed a two-megawatt woodchip-fired boiler to reduce gas used for heating. Single-engine taxiing has been introduced to reduce emissions from aircraft on the ground. Motion sensors have been built into escalators and low-energy lighting has been installed in offices and on the airfield. Staff have been encouraged to turn off electrical equipment overnight.
Stansted is regulated under the Carbon Reduction Commitment. Achieving the Carbon Trust Standard will boost its position in the first CRC performance league table, to be published next year (ENDS Report, September 2010).
Stansted’s direct emissions – those from buildings, infrastructure and vehicles – were 53,162 tonnes in 2009, down from 54,825 tonnes the previous year. Only direct emissions fall under the CRC.
Its indirect emissions – those from aircraft landing and taking off up to a height of 3,000 feet and passenger and staff travel – amounted to 419,197 tonnes in 2009.
Andy Jefferson, Stansted's head of health, safety and environment, said: "While celebrating this success, we also know there is more we can and must do. About 92% of emissions from our buildings are generated by electricity use, so we've set a challenging target to reduce 2010 levels by 5% compared to 2009.”
