Porterbrook’s sustainability framework is built on five central pillars
Growing rail’s modal share
Our role is to facilitate the increase of rail’s modal share and support the decarbonisation of the wider transport sector. We do this by investing in trains, innovation and infrastructure across the UK.
Adopting the highest standards of governance and behaviours
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 2025, we were named Sector Leader in Transport for the fifth year in a row, with a top score of 100/100 and a five-star rating.
Cultivating environmental sustainability
As a rolling stock company with over 4,000 vehicles, our environmental impacts are primarily indirect and linked to our asset portfolio. We actively engage with industry partners across the value chain to minimise this shared footprint.
We aim to achieve positive impacts within our direct operations. An ISO 14001:2015 certified Environmental Management System is in place to manage performance, and Long Marston has an approved 10% Biodiversity Net Gain target.
Improving climate resilience
We are working with industry partners to deliver award-winning innovations that strengthen the resilience and safety of our assets—and the wider rail network.
Investing in people and communities
At Porterbrook, we empower staff to grow as skilled professionals whilst embedding diversity and inclusion.
We actively engage with communities to share our experience and inspire the next generation of railway professionals.
