Key targets


We’re reducing carbon emissions across operations by focusing on our vehicles, infrastructure, and innovative products and services.

Carbon data

Using the latest technology, we’re continually measuring and reviewing our carbon emissions. We categorise these into three ‘Scopes’ – a method developed by the most widely used global accounting tool, the Greenhouse Gas Protocol. Scopes 1 and 2 cover direct and indirect emissions resulting from business operations, while Scope 3 includes all other indirect emissions that are part of our value chain but lie outside standard operations. By our calculations, the total CO2e per parcel is currently 467g.

Scope 2022/23 Total (t.CO2e) 2021 Total (t.CO2e)
Scope Scope 1 2022/23 Total (t.CO2e) 60,320* 2021 Total (t.CO2e) 68,060
Scope Scope 2 - Location Based (LB) 2022/23 Total (t.CO2e) 5,361* 2021 Total (t.CO2e) 5,387
Scope Scope 2 - Market Based (MB) 2022/23 Total (t.CO2e) 0 2021 Total (t.CO2e) 4,208
Scope Scope 3 - All categories reported 2022/23 Total (t.CO2e) 241,374 2021 Total (t.CO2e) 263,976
Scope Total S1, 2 & 3 (LB) 2022/23 Total (t.CO2e) 307,054 2021 Total (t.CO2e) 337,424
Scope Total S1, 2 & 3 (MB) 2022/23 Total (t.CO2e) 301,693 2021 Total (t.CO2e) 336,244
Scope Scope 1 and 2 total (MB) 2022/23 Total (t.CO2e) 60,320 2021 Total (t.CO2e) 72,228

Ongoing exploration of alternative fuels for our fleet has put us in a really strong position across the first, middle and final mile as we head towards net-zero.

We use a biomethane compressed natural gas (CNG) powered fleet as an alternative to diesel. In 2023 we added 30 new Bio-CNG tractor units, bringing the total to 190 – 52% of our core tractor fleet. This means that 54% of our first mile fleet is powered by bio-CNG, and 31% of our entire core fleet is low-carbon.

Each new unit reduces CO2 emissions by more than 80% when compared to a Euro 6 diesel vehicle – a reduction of 150 tonnes of CO2 per vehicle and 24,000+ tonnes of CO2 across the entire Bio CNG fleet annually.

Other CNG benefits include reductions in air pollution impact, such as 70% less NOX, 99% less particulate matter, 90% less NMHC and 88% less methane. They’re also 50% quieter than diesel equivalents.

We partner with CNG Fuels, which sources 100% renewable bio-CNG for its stations. This is sourced from food waste, independently verified and approved by the Department for Transport’s Renewable Transport Fuel Obligation.

Our London Gemini site operates with 100% electric vehicles to service final-mile deliveries in central London, and in 2022/23 we doubled the number of zero-emission electric vans bringing the total to 37% of our total van fleet. 168 new zero- emission electric vans to support our out-of-home ParcelShop network. We aim to undertake all ParcelShop collections with electric vehicles at the earliest opportunity, and we’re installing charging points at our hubs and depots.

Our infrastructure of hubs, depots and delivery units is a key part of our overall roadmap to become a low-carbon delivery business. We have already converted 100% of our purchased energy to REGO- backed (renewable energy guarantee of origin) UK renewables in our whole operation.

Our flagship 55-acre ‘superhub’ at Barnsley, which opened in 2022, includes solar panels, rain harvesting and acoustic bunds to help reduce noise pollution. There’s also a substantial biodiversity area to support local wildlife, and we’ve planted more than 25,000 new trees and hedgerows.

This builds on other eco-features we’ve already got in place elsewhere in our network. For example, our Rugby hub features transparent roof sections to increase natural lighting and LED lighting throughout to save energy. There’s a rainwater harvesting system and around 77% of waste is recycled.

Products and Services

Our proposition, developed and trialled in our bespoke Innovation & UX Lab, helps customers and retailers become more sustainable. Many of our innovations can easily be integrated into our clients’ checkout process as we support them on their own sustainability journeys.
