In 2025, Trainline reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Trainline reported 21,135.88 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2025 disclosure of Trainline includes a breakdown across 9 of the 15 Scope 3 categories defined by the GHG Protocol, up from 0 in 2024, reflecting improved emissions accounting practices and greater transparency across the company's value chaina
In 2025, Trainline reported total Scope 3 emissions of 21,135.88 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 98.06% of these emissions originated from upstream activities such as purchased goods and capital goods, while 1.94% came from downstream activities like product use, distribution, and end-of-life treatment.a
In 2025, Trainline reported emissions for 9 out of the 15 Scope 3 categories defined by the GHG Protocol.a
This partial disclosure allows for some insight into the company's indirect impacts.
In 2025, the largest contributors to Trainline's Scope 3 emissions were:a
In 2025, Trainline reported Scope 1 greenhouse gas (GHG) emissions of 89.43 tCO₂e and total revenues of USD 557 millions. This translates into an emissions intensity of 0.16 tCO₂e per millions USD.a
In 2025, Trainline reported a Scope 1 emissions intensity of 0.16 tCO₂e per millions USD. Compared to the peer group median of 0.44, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Trainline ranked 8 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Trainline is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Trainline reported a total carbon footprint of 21,475.46 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 6,766.21% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.ab
The largest contributor to Trainline's total carbon footprint was Scope 3 emissions, accounting for 98.42% of the company's total carbon footprint, followed by Scope 2 emissions at 1.16%.a
