Transitioning our business to Net Zero - the climate, nature and wider environmental challenges present both risks and opportunities for our business.

Our targets

In 2024 we had our Science Based Targets (SBTs) validated by the Science Based Targets initiative (SBTi).

In 2025, we:

Achieved a 32% reduction of operational emissions vs 2022.
Achieved a 26% reduction in business travel and fuel-and energy-related emissions vs 2022.
Dropped from 15% in 2024 to 10% of suppliers by emissions with SBTs in place.

Operational emissions

We prioritise the avoidance and reduction of GHGs through energy and resource efficient operations, the use of renewable energy, and efforts to decarbonise our fleet, buildings, and client assets. Highlights include:

Retained 100% renewable sourced electricity for the first time across our global operations.
Increased our proportion of hybrid and electric fleet vehicles to 39%, up from 25% in 2022.

Climate transition planning and Net Zero Action Plan (NZAP)

Our Climate Transition Plan (CTP) continues to evolve and mature. It shapes our approach to meeting our Net Zero targets, addressing our climate risks and opportunities and, in future, will also include a more strategic approach to managing nature impacts in our direct operations and supply chain. Our CTP is complemented by operational Net Zero Action Planning.

Our UK & Europe Division, accounting for the largest share of Serco’s operational emissions, implemented a comprehensive NZAP in 2025 to accelerate progress toward Net Zero by 2050 or sooner. The Division also introduced the “Together to Zero” framework to strengthen collaboration with customers, partners and suppliers.

Business travel

Our business travel emissions reduced by 21% in 2025 vs 2022. We introduced a global travel and expenses policy in 2025 and benefitted from significant reductions in air travel emission factors as well restating our North American emissions based on an updated methodology reviewed by Accenture.

Our supply chain

The emissions within our supply chain represent the biggest proportion of Serco’s Scope 1, 2 and 3 GHG emissions, at 59% in 2025. To address these emissions, and wider sustainability impacts from our supply chain, we have implemented a Net Zero Standard for our suppliers. Find out more about our Net Zero Standard.

Environmental protection and supporting nature

We recognise that our environmental sustainability strategy must take biodiversity and the natural environment into consideration alongside emissions reduction. The planetary crisis we face is multi-faceted, and achieving Net Zero is not possible without also supporting the natural environment and the ecosystems underpinning it.

Highlights include:

Expanded our work to better understand our impacts and dependencies on the natural environment using the tools recommended by the Taskforce on Nature-Related Financial Disclosure (TNFD)
Remained members of the TNFD Forum

We continue to deliver services for government customers which help to facilitate critical nature and biodiversity scientific monitoring and protection.

Case study

Deepening society’s understanding of climate change and nature’s role Serco plays an integral role in the European Space Agency’s Biomass mission. This state-of-the-art satellite initiative is dedicated to deepening society’s understanding of climate change and nature’s role in regulating the Earth’s climate.

Serco is now responsible for the daily operation of the satellite’s ground data systems, managing and processing all information collected from space.

The focus of the Biomass satellite is on monitoring forests worldwide. Using advanced radar technology, the satellite measures the amount of biomass - such as trees and other vegetation - present on the planet. The resulting data is supporting scientists to understand how forests store carbon and how fluctuations in forest health can impact the global climate.
