At Porterbrook sustainability is integral to everything we do. Our ambition is to be recognised as market leaders in sustainable rail leasing and asset management support.

To remain at the heart of future transport modes, the railway needs to transition to cleaner energies whilst crucially improving capacity and connectivity, in a responsible way.

As the owner of over a quarter of Britain’s rolling stock, we believe that we have a leading role to play. We are committed to working with our customers and suppliers, as well as national and devolved governments, to deliver a carbon neutral economy with increased productivity at its heart.

Benchmarking our sustainability performance

Porterbrook’s sustainability is assessed annually through GRESB, which involves scoring and comparing organisations based on their environmental, social and governance management and performance.

In 2023, we were named Sector Leader in Transport for the second year in a row, with a top score of 100/100 and a five-star rating. 

In our 2022 Sustainability Report, we outline the progress made on our sustainability journey and set out our ambitions for the years ahead

Porterbrook is committed to transparent reporting and will further enrich its environmental, social and governance disclosures over the coming years.

We are committed to helping build tomorrow’s sustainable railway


Our commitment to sustainability spans each stage of the asset life cycle, from ISO 20400:2017-aligned sustainable procurement to responsible decommissioning, our whole-life asset management approach is underpinned by an ISO 14001:2015-certified Environmental Management System with innovation at its heart.
