Renewables & Electrification: Royal Mail's Path to Net Zero
Royal Mail’s 2024–25 Environmental, Social and Governance (ESG) Report shows its efforts to become the UK's greenest parcel operator.
The company has made progress towards its net zero 2040 goal through decarbonisation, operational efficiency, biodiversity and circular economy strategies.
Royal Mail has reported a 25% decrease in its overall greenhouse gas emissions (GHGs) since its 2020–21 base year, including a 27% drop in direct (Scopes 1 and 2) emissions and a 24% decrease in Scope 3 value chain emissions.
A key driver of this reduction is its rollout of approximately 7,000 electric vans, elevating zero-emission delivery routes to 31%.
The company also transitioned to the use of biofuel, more that 27 million litres of Hydrotreated Vegetable Oil (HVO) were used in its large truck fleet, saving an estimated 44,000 tonnes of CO₂e.
In addition, ceasing 16 domestic air routes and favouring road and ferry alternatives has halved domestic airmail emissions.
“Our average carbon per parcel has now reduced to 165g CO2e, which is the lowest in the industry,” writes Alistair Cochrane, CEO of Royal Mail, in the report.
Sustainable delivery and operations
Royal Mail’s model includes one of the largest electric van fleets in the UK and more than half of its routes being primarily on foot, significantly lowering final-mile delivery emissions.
The company has invested in developing green skills, training more than 22,000 employees in electric vehicle operation and certifying a third of mechanics for EV maintenance.
Through partnerships such as with Wiliot, parcel containers are tracked to enhance loading efficiency, reduce carbon impact and prevent unnecessary mileage.
Royal Mail’s commitment extends to its properties, where 100% of its sites now operate on renewable electricity.
Efforts to replace gas boilers with air source heat pumps and on-site solar energy, complemented by energy-efficient LED lighting and water-saving technology implementations, have made a change to its impact.
Value chain decarbonisation
With 70% of emissions arising from its value chain, Royal Mail has significantly enhanced Scope 3 reporting and supplier engagement.
It has integrated granular carbon accounting with supplier-specific data to better track emissions in procurement decisions.
Environmental requirements have also been launched for vendors alongside a multi-phase engagement programme targeting its top-emitting suppliers.
The company is actively working with suppliers on initiatives such as product life extension, IT equipment reuse and the incorporation of recycled materials into uniforms and packaging.
Environmental stewardship
Royal Mail says it has made circularity a core pillar of its sustainability agenda.
It has:
- Achieved a 24% reduction in waste generated since 2020–21.
- Diverted 97% of its waste from landfill.
- Supported customer circular models, such as:
- Recycling 1 million coffee pod bags with Nespresso
- Supporting second-hand sales on eBay and fashion resale platforms
- Enabling returns of electronic devices for reuse and recycling
- Co-founded PrintGreen, an industry-wide initiative to reduce the carbon impact of direct mail and boost sustainable print practices.
Beyond emissions, Royal Mail manages environmental risk through a certified ISO 14001:2015 environmental management system.
In 2024–25 no environmental enforcement actions were reported.
The report states that biodiversity initiatives included the planting of 17 wildflower meadows and the installation of 47 bird boxes.
The company also joined the initiative No Mow May to enhance pollinator habitats across 60 sites.
“The results are in … Royal Mail is the UK’s greenest parcel operator based on average emissions per parcel delivered,” writes Matt Gower, Head of ESG at Royal Mail, on LinkedIn.
