EVs, Electrification & Energy: Royal Mail's Net Zero Pursuit

Royal Mail is combining fleet electrification, renewable electricity and more efficient operations as it works towards its target of reaching net zero by 2040.

The company's Sustainability Report 2025-26 outlines how its Steps to Zero strategy is reducing emissions across one of the UK's largest logistics networks through investment in electric vehicles, clean energy and lower-carbon supply chains.

Alongside expanding zero-emission transport, Royal Mail is improving the energy performance of its estate, strengthening responsible procurement and embedding circular economy principles throughout its operations.

Together, these initiatives are helping to lower emissions while supporting deliveries to around 32 million addresses across the United Kingdom.

Electrifying transport to reduce emissions

Transport remains one of the biggest opportunities for Royal Mail to cut emissions and reduce its dependence on fossil fuels.

The company now operates the UK's largest electric delivery fleet, with 8,800 electric vans in service across its nationwide network.

These vehicles now support 31% of delivery routes, making electric mobility an increasingly important part of Royal Mail's decarbonisation strategy.

“We’ve reduced our emissions by 31% across all scopes compared to our base year of 2020-21, keeping us on track towards our target of net zero by 2040,” says Alistair Cochrane, CEO of Royal Mail, in the report.

"At the same time, our average carbon per parcel fell to 164g CO₂e, the lowest in the industry.

“We are committed to doing business the right way, by delivering for our customers while creating lasting value for people across the UK.”

Over the past 12 months, Royal Mail has added more than 2,000 electric vans to its fleet while installing charging infrastructure at almost 400 operational sites.

The business has also introduced its first eight 42-tonne electric heavy goods vehicles to move parcels between major hubs, alongside more than 80 micro electric vehicles.

Elsewhere, fully electric drones are now operating a daily inter-island postal service in Orkney, transporting around 1,000kg of mail and reducing delivery times by as much as 24 hours compared with ferry services.

Improving energy performance across the estate

Buildings account for around 7% of Royal Mail's overall carbon footprint, making energy management a key component of its net zero strategy.

Since 2023-24, all purchased and generated electricity used by the company has come from a 100% renewable electricity tariff, helping to reduce emissions across its property portfolio.

Royal Mail has also introduced a site-level performance dashboard that enables local teams to monitor energy consumption and identify opportunities to improve efficiency.

Digital technology is supporting these efforts in other areas of the network.

Location-tagging across 850,000 wheeled containers allows vehicles to be loaded more effectively, reducing unnecessary journeys and the fuel consumption associated with inefficient logistics.

“Royal Mail’s Low Carbon Transition Plan brings us a step closer to understanding the roadmap, while being clear that we cannot do this alone,” writes Miles Durrant, Head of Climate Strategy at Royal Mail, on LinkedIn.

“Achieving decarbonisation depends on an economy-wide transition: progress in technology, supportive policy, supplier action, infrastructure, and the skills to deploy low-carbon solutions at scale.

“Done well, that transition can support energy security, grow the green economy and create skilled jobs across the UK.

“That’s why I’m particularly pleased that we recently announced a £1m (US$1.34m) apprenticeship fund to help build green skills in areas such as low-carbon heating, EV infrastructure, energy-efficient construction and sustainable supply chains. The direction is clear. Now the focus has to be delivery.”

Alongside reducing energy use, Royal Mail continues to improve water efficiency across its estate.

The business consumes approximately 1.3 million cubic metres of water each year, primarily in vehicle washing facilities and workplace amenities.

Automatic Meter Readers now monitor 54% of the company's water consumption, while trials of upgraded toilet flush controls have delivered local reductions in water use of up to 50%.

Lowering emissions across the supply chain

Indirect emissions remain Royal Mail's largest carbon challenge, accounting for 68% of its total emissions footprint.

The company reports that it has reduced Scope 3 emissions by 32% compared with its 2020-21 baseline, achieving its original 2030 target five years ahead of schedule.

The reduction has been supported by tighter cost management, cleaner electricity generation across international grids and the removal of 18 domestic flight routes in favour of road transport.

To strengthen collaboration with suppliers, Royal Mail has introduced a dedicated portal that allows around 130 priority suppliers to submit verified environmental data.

This information forms the basis of the First Class Sustainability Programme, launched in April 2026.

The programme measures suppliers against bronze, silver and gold sustainability standards, with key suppliers expected to achieve at least silver status within agreed timeframes.

Supporting circular operations

Reducing material consumption is another pillar of Royal Mail's environmental strategy.

Working with waste management partner Biffa, the company generated 30.3 kilotonnes of waste during the reporting year, representing a 25% reduction compared with its baseline.

The business is extending the lifespan of operational assets including wheeled containers and mail sacks while encouraging stronger waste segregation across its workforce.

Royal Mail's logistics network is also supporting wider circular economy initiatives by enabling return and reuse services for businesses and consumers.

Its partnership with Nespresso led to the recycling of one million bags of coffee pods during the programme's first year.

The network also supports the return and refurbishment of products including Wi-Fi routers for major telecommunications providers, as well as clothing resale through online marketplaces.

Meanwhile, a stock donation initiative with the British Heart Foundation has diverted 21.86 tonnes of unwanted goods from landfill, extending product lifecycles while generating additional funding for the charity.
