We know that having access to natural environment areas, parks and green spaces, is important to local communities, so our expansion plans include proposals for investment in the creation of new and enhanced areas.

While many factors affect quality of life, we have learned that one of the most important for local people is being able to influence decisions made in your community.

That’s why we’ll be working collaboratively with local people and stakeholders to enhance the environment around Heathrow for the benefit of everyone who lives there. For example we will look to improve the quality of the habitat for watercourses to the east of the airport and increase their public amenity value, and new green areas and development will support the already strong biodiversity in the area. In 2016, it was discovered that there are 2,836 different species of plants and creatures which can be found across the 170 hectares of local biodiversity sites managed by the airport.

Environmental Impact Assessment – The Process

As Expansion is a Nationally Significant Infrastructure Project (NSIP), we are required to undertake an Environmental Impact Assessment (EIA). The EIA process will play an important role in the development of the proposals as it will ensure environmental and social considerations are taken into account. The EIA process will test the performance of the proposals on a number of topics, such as air quality, biodiversity, noise, and socio-economic, ensuring there are measures to avoid, reduce or mitigate the impacts.

There are three formal stages to our EIA, with more information below. Through the evolution of our proposals we will work with stakeholders on the appropriate scope and scale of the EIA, consult widely on the preliminary findings of the EIA process as part of the statutory consultation allowing local residents to have a say, and submit an Environmental Statement to support the DCO application.

Environmental Impact Assessment Scoping Report

Known as the EIA Scoping Report, this is a technical document covering the wide-range of environmental and sustainability topics. It sets out our approach to EIA for expansion and specifically the baseline information and methodologies our teams will use to assess the proposals.

We submitted the EIA Scoping Report to the Planning Inspectorate on 19th May 2018 and asked they provide an opinion on the scope and level of detail of information to be provided in the Environmental Statement. The Planning Inspectorate undertook a 4 week consultation with statutory consultees and issued the Scoping Opinion on their website on 2nd July 2018.

Environmental Impact Assessment: Preliminary Environmental Information Report (PEIR)

Within our Airport Expansion Consultation, which ran from 18th June to 13th September 2019, we published our Preliminary Environmental Information Report (PEIR) which sets our initial conclusions on the ‘likely significant environmental effects’ of our Expansion Project.

Sitting alongside the PEIR is a Non-Technical Summary which provides a summary of the full Preliminary Environmental Information Report using less technical language. It is a good place to start reading about the potential environmental effects of the Expansion project and how we propose to avoid, reduce or offset significant adverse environmental effects.
