Fleet of the future

Fleet electrification remains one of the most significant opportunities for organisations to reduce operational emissions while supporting the transition to a low-carbon economy. Through its Plan Zero strategy, Mitie continues to expand the adoption of electric vehicles (EVs), combining fleet transformation with investment in charging infrastructure and colleague-focused mobility solutions.

During FY26, Mitie further accelerated its transition towards a fully electric fleet through the mobilisation of 22 new contracts, 19 of which deployed fully electric vehicles. This introduced 468 EVs into service, helping increase the proportion of Mitie’s legacy fleet that is fully electric to 76%. Following the acquisition of Marlowe, electrification across the enlarged Group fleet stood at 67%, exceeding our FY26 target of 64%.

Minimising waste through ReWorkwear

We use circular economy principles to cut emissions and embed sustainability in our procurement decisions. Our efforts in reusing Mitie workwear highlight the potential of this approach. By analysing our purchasing patterns, we buy over 300,000 workwear garments every year. However, the natural resources required to produce new clothing textiles are not environmentally friendly: one t-shirt demands 700 gallons of water1, while producing 1kg of fabric releases up to 23kg of greenhouse gases2 into the atmosphere due to processing, manufacturing and distribution.

To tackle the challenge, we have developed a workwear reuse scheme. ReWorkwear ensures that good condition Mitie workwear remains in circulation, minimising waste and reducing our demand for new clothing. Following collection, the workwear is quality checked, laundered and repaired as necessary. Any items not suitable for reuse are recycled. In FY24, our trial collected 700 garments from Mitie contract teams to assess the impact and viability of the project. So far, 47% of these garments can be reused. We aim to expand this scheme each year to eventually cover 100% of our operations, which would save almost 500 tonnes of CO2e annually.

The Farm at The Shard

In 2023, we installed three Farm Stands in Mitie’s HQ office, The Shard in London. Farm Stands are hydroponic (no soil) systems for growing plants and herbs such as kale, basil and oregano. Installed and maintained by Square Mile Farms, every quarter we complete 11 harvests, engage nearly 160 people, and grow over 32kg of produce – that’s around 608 portions. Over this period, The Farm Stands method has saved nearly 500 litres of water compared with standard growing systems. Many colleagues, customers and visitors have benefitted from these stands: “I love this. My kids are getting a big, healthy meal tonight.”

The Mitie estate decarbonisation

Approximately 2% of Mitie’s Scope 1 and 2 emissions (direct, operational) originate from the gas and electricity consumption within our estate. To reduce our carbon emissions, we are degasifying the heating systems at our sites to eliminate our reliance on fossil fuels, replacing them with low-carbon solutions. We now have 28 decarbonised sites (up from 16 in FY25), 13% of our estate, with 5 of these completed during FY24. To achieve this decarbonised status, we have been replacing gas boilers with low-carbon heat pumps and installing LED lighting.

We also focus efforts on ensuring our buildings are running at optimal levels. Using our in-house expertise around energy efficiency, our Energy Managers explore innovative solutions to create smart, connected workspaces. By implementing measures such as setting time schedules and selecting energy saving modes at one of our sites, we will save just under 66 tonnes of CO2e as well as over 323,000 kWh, annually.
