We have set tough environmental targets for a third runway in terms of the airport’s use of natural resources – water, waste and energy.


Both the Airports Commission and the Committee on Climate Change have found that a third runway is compatible with the UK meeting its climate change target of 37.5MtCO2 emissions from aviation by 2050.

We are committed to making the operation and construction for a third runway as environmentally friendly as possible.

As a result, compared to our baseline of 2010 the expanded airport will consume less water, produce at least 60% less carbon from energy and result in less waste per passenger.

This is to be achieved by investing in new technology and practices that will improve the efficiency of the airport as well as taking advantage of substantial public transport upgrades.

Our innovative green space approach

We have developed an integrated strategy for flood protection, biodiversity and landscape. The strategy will eventually form part of a Local Plan that realigns watercourses and creates new areas of flood storage in an enhanced Colne Valley Park.


Our plans see existing river routes diverted and redesigned so as to create new areas of flood storage that, with the introduction of other measures, would improve flood protection for local communities.

Our plans aim to provide better links and access to local countryside and improved recreational facilities. We aim to increase the amount of publicly accessible green space that exists around the airport and to create an enhanced environment for biodiversity.

We’ve proposed £105m towards these initiatives within our proposal, which will lead to public green spaces growing around the airport to be approximately four times the size of Hyde Park.

This will create new green corridors that can link together existing outdoor recreation areas, such as those found in the existing Colne Valley Regional Park and at Cranford Park.

New opportunities and building on our biodiversity strength

There are already 2000 species of flora and fauna in the 100 hectares of biodiversity spaces Heathrow manages – and we are looking to build on this strength with expansion.

New green spaces will be designed to form an interconnected wildlife network, maintaining natural habitats and delivering improvements for biodiversity.

There are also opportunities to provide new public facilities which we are exploring – looking at things like picnic areas, horse riding areas, mountain bike trails, outdoor gyms and a swimming pool.
