Purpose-driven environmental sustainability

Empowering people to make greener travel choices

At Trainline, environmental sustainability is fundamental to our purpose. Through our technology and data, we make rail travel easier, empowering people to make travel choices that are better for the environment.

Rail offers travellers a greener alternative to flying or driving, creating 87% less CO2 emissions than air travel and up to 67% less CO2 emissions compared with car travel, per passenger. It can move millions of people quickly and cleanly, for leisure or business, across countries and continents.

We believe we have a key role to play in supporting the rail industry, businesses, and governments in meeting their emissions targets.

Our cross-functional sustainability team is dedicated to encouraging modal shift; promoting rail as a more sustainable way to travel; and reducing the impact on the climate from our own operations.

The external context

UK and European governments have continued to encourage modal shift to rail and increase their investment in rail in order to meet their net zero emissions goals. The EU is targeting a 55% reduction target for CO2 emissions by 2030, and the UK has a reduction target of at least 78% by 2035 and a legally binding target to reach net zero by 2050.

Cars and planes create 58% of the UK’s transport CO2 emissions, whereas the entire rail network creates less than 1%. The UK Decarbonising Transport plan highlights rail as “the greenest form of motorised transport”. It sets a target of achieving net zero greenhouse gas emissions from trains by 2050, through increased electrification of the rail network and introduction of new technologies such as hydrogen-powered trains.

We are already seeing the impact of this transition to rail in the UK, for example, with Lumo carrying one million passengers between Edinburgh and London since its launch, resulting in rail now being the favoured mode of transport between the two cities. Similarly, in Europe, cars and planes create 74% of transport CO2 emissions, and the entire rail network adds up to less than 1%. The EU Commission has highlighted rail as playing a key role in the EU becoming climate-neutral by 2050. It targets the doubling of high-speed rail traffic by 2030 and a tripling of high-speed rail by 2050. Third-party ticket vendors such as Trainline have been identified as having a key role to play in the delivery of elements of this plan.

In the last year, European governments have taken further steps to encourage modal shift from cars and planes to rail to achieve their carbon reduction targets. France introduced a ban on internal short-haul flights, those under two and half hours, which was formally validated by the European Commission in December 2022. KLM is also encouraging passengers to take the train rather than fly on some short-haul flights as the Dutch government cuts the number of flights from Amsterdam Airport Schiphol to cut air pollution.

Product and promotion

Our aim is to empower people to make greener travel choices, driving a modal shift that benefits people and the planet.

Trainline has a key role to play in engineering the travel habits of the future and enabling people to choose the most sustainable transportation option.

During the year, we launched a new consumer campaign that celebrates all the heroes who travel by train. We also introduced new features on our Mobile App and on Web to encourage modal shift, including “Your Sustainability Story”, which informs and educates customers on their emission savings vs other forms of transport.

We also continue to support the “I Came By Train” campaign, which aims to grow the public’s awareness of the relative benefits of train travel and inspire pride in those that take positive action. We gained strong early momentum with industry and government stakeholders with the launch of a white paper on how the rail industry can encourage more people to choose rail.

This year, the campaign has analysed 250,000 UK rail routes to create the Reasonable by Rail database which shows when trains beat planes or cars for speed and savings. This data has been made available for government and industry stakeholders and powers Trainline’s Super Routes feature.

What we’re doing

We steer customers to etickets where available to reduce paper ticket waste, promote rail cards to encourage a modal shift and in the UK and France show customers the CO2 emissions of their chosen journey. We are making green data more accessible and transparent on our platform to allow customers to better understand and reduce the carbon impact of their journey and continue to build awareness around the benefits of using rail and coach instead of car or plane.

Trainline has committed to taking urgent action to help limit the rise in global temperatures by becoming one of the first companies in the tech sector to have ambitious science-based net zero targets officially approved.

Trainline’s net zero target commitments have been officially verified by Science-Based Targets Initiative (SBTi), the global body enabling businesses to set ambitious emissions reduction targets in line with climate science. Trainline commits to reaching net-zero greenhouse gas emissions by 2040. Trainline also commits to near-term target reducing scope 1 and 2 emissions by 55% by 2030.

We have participated in voluntary offsetting since FY2021. For FY23, we have offset our operational greenhouse gas emissions by investing in the Klim Soil Project. Klim soils are the second largest carbon sink in the world and hold more carbon than the atmosphere and all plants combined. Trainline have purchased removal credits to offset the impact of our Scope 1, 2 and select Scope 3 categories: business travel, waste, water and data centre usage. In total, Klim credits contribute to seven Sustainable Development Goals. 

We have a sustainability policy as well as an energy and carbon policy, which you can find here:

Environmental Data

EcoAct has provided independent third-party limited verification of Trainline plc's direct (Scope 1) and indirect (Scope 1 and Scope 3) greenhouse gas (GHG) emissions. The GHG emissions have been assessed following the ISO 14064-3:2019 standard. 

The table below summarises the Group's UK and Global GHG emissions for the latest financial reporting year FY2024, 1st March 2023 to 29th February 2024, and the year FY2020, 1st March 2019 to 28th February 2020.
