[News] Pledge to Net Zero – 2025 Carbon Emissions Report
As part of our ongoing commitment to climate action, Catalyst continues to support the Pledge to Net Zero, an industry-led initiative focused on accelerating the transition to a net zero carbon economy.
2025 Carbon Emissions Overview
In 2025, Catalyst reported total greenhouse gas emissions of 430.59 tCO₂e, covering direct emissions from fuel combustion (Scope 1), indirect emissions from purchased electricity (Scope 2), and wider value-chain emissions (Scope 3).
Our tCO2e emission intensity was 390.67 tCO₂e in 2024 and 430.59 in 2025 which, adjusted for the business’ 7% revenue growth over the period, represents a 3% year on year increase.
Assessing emissions in relation to business growth provides additional context for interpreting performance and supports a more meaningful understanding of emissions trends as the company continues to expand
Compared with 390.67 tCO₂e in 2024, this represents a 10.2% increase in reported emissions year-on-year. The increase is largely attributed to improved data completeness and the expansion of our reporting boundary to include our London office, as well as enhanced categorisation of procurement-related emissions. Despite this increase in total reported emissions, we achieved a 28% reduction in Scope 1 emissions, primarily driven by reduced fuel consumption and the continued electrification of our vehicle fleet.
Scope 3 emissions continue to represent the majority of our footprint, accounting for approximately 95.7% of total emissions, with purchased goods and services and business travel remaining the largest contributors.
Progress Towards Our Science Based Targets
Using 2024 as our baseline year, Catalyst has committed to reducing Scope 1 and Scope 3 emissions by 42% by 2030, aligning our climate strategy with the Science Based Targets initiative (SBTi) and the global 1.5°C pathway.
To support progress toward this target, Catalyst is implementing several operational and data-driven initiatives:
- Fleet electrification – transitioning company vehicles to electric models as leases expire.
- Energy efficiency improvements – upgrades to our Dublin office including insulation and triple-glazed windows to reduce heating demand.
- Reducing travel emissions – minimising inter-regional travel and reducing company-wide in-person meetings.
- Improved emissions tracking – using the Obi ESG platform to strengthen data management and monitor progress against our climate targets.
As Catalyst continues to grow across Europe, we remain focused on ensuring that emissions growth does not outpace business growth, while identifying opportunities to reduce emissions across our operations and supply chain.
