Manchester Airports Group has reported a 41% drop in the number of noise complaints at its four airports.
The owner of Manchester, London Stansted, East Midlands and Bournemouth Airports said the number of complaints per 1,000 movements fell from 7.93 in 2014/15 to 4.68 in 2015/16.
It also claimed a 15% reduction in carbon emissions.
Releasing its Corporate Social Responsibility Report for 2015/16, it said the group delivered £6.2bn of economic value for the UK economy during the period, a 16% rise.
It said this comes on the back of its most successful year ever which culminated in nearly 52 million passengers using its airports, an increase of 7%.
CSR director Neil Robinson said: "In a year when we have transported a record 50 million passengers, we have managed to significantly reduce our environmental impact through a variety of initiatives such as the introduction of GPS flight path technology that has cut our noise impact and also managing to make Manchester Airport’s ground operations carbon neutral.
"As the North’s Global Gateway, Manchester Airport will do more than any other UK airport to drive the Northern economy forward, providing international connectivity directly from the region.
"Similarly, Stansted’s growth over the next 10 to 15 years will not only provide much-needed airport capacity in the South, it will also play a key role in supporting economic development and employment in London and the East of England."
