Getting to work accounts for a surprisingly large chunk of the UK's carbon emissions. Transport is now the country's biggest emitting sector, responsible for around 30% of all domestic greenhouse gases. And commuting plays a major role in that, contributing an estimated 18 million tonnes of CO2e every year.
The good news? There are practical, tax-efficient ways for both employers and employees to cut commuting emissions. From the cycle to work scheme to EV salary sacrifice, car sharing, and hybrid working, sustainable commuting options have never been more accessible or financially rewarding.
This guide covers everything you need to know about green commute options in the UK, including how each scheme works, what tax savings are available, and how to measure the impact.
UK domestic transport produced 110.1 million tonnes of CO2e in 2024, according to provisional DESNZ data. Cars and taxis alone account for 60.2 million tonnes of that. To put it in perspective, commuting generates roughly 5% of the UK's total emissions.
The average English commuter travels just over 1,000 miles per year for work across 111 trips, with the typical one-way journey taking about 29 minutes. And despite post-pandemic shifts toward flexible working, 68% of commuters in Great Britain still travel by car.
That said, things are shifting. The Mobilityways 2024 Commuter Census found that single-occupancy vehicle commuting has dropped to a record low of around 38 to 43%, down from 46% in 2022. Walking hit a record high, and bus use rose 17% year-on-year following the 2 pounds fare cap. Overall transport emissions in 2024 remained 10 to 12% below 2019 levels, suggesting the pandemic created a lasting change in how we get to work.
If your organisation wants to go further in reducing its office carbon footprint, tackling commuting is one of the most impactful places to start.
The cycle to work scheme is one of the most popular employee benefits in the UK, and for good reason. It lets you get a bike and safety equipment at a significant discount through your employer.
Your employer buys or leases a bike on your behalf. You then pay for it through salary sacrifice, meaning the cost comes out of your gross pay before tax and National Insurance. This runs over a 12-month hire period. At the end, most people choose the "own it later" option, paying a small fee (typically 3 to 7% of the original price) to keep the bike.
The savings depend on your tax band:
| Tax Band | Income Tax | Employee NI | Combined Saving |
|---|---|---|---|
| Basic rate | 20% | 8% | 28% |
| Higher rate | 40% | 2% | 42% |
| Additional rate | 45% | 2% | 47% |
So a basic-rate taxpayer buying a 1,000 pounds bike saves roughly 280 pounds, bringing the net cost to around 790 pounds after the ownership fee. A higher-rate taxpayer saves even more, paying around 650 pounds net for the same bike.
Employers benefit too. With Employer NICs rising to 15% from April 2025, every 1,000 pounds of salary sacrifice saves the employer approximately 150 pounds in National Insurance contributions.
The scheme is effectively uncapped. While an FCA exemption exists for agreements under 1,000 pounds, FCA-authorised providers like Cyclescheme, Halfords, and the Green Commute Initiative can facilitate purchases at any value. Your employer may set their own limit, but there is no government-imposed cap. Despite rumours ahead of the November 2025 Budget, the Treasury confirmed no changes to the scheme.
You can get any pedal cycle, electrically assisted pedal cycles (e-bikes with motors up to 250W that cut out at 15.5 mph), and safety equipment like helmets, lights, locks, panniers, and reflective clothing. E-scooters are not included.
Over 2 million people have used the scheme since 1999, across more than 53,500 employers. Around 209,000 employees claimed in the most recent year, a 25% increase from 2019/20. The scheme generated 219 million pounds in bike sales in 2023/24. Most importantly, 38% of scheme participants are new cycling commuters who would not otherwise have cycled to work.
Key providers include Cyclescheme (the largest, with 2,600+ retail partners), Halfords Cycle2Work, Evans Cycles Ride-to-Work, and the Green Commute Initiative (a social enterprise with no spend limit). In 2024, CycleSaver launched the first salary sacrifice scheme for bike-share subscriptions, covering services like Lime and Santander Cycles.
If cycling is not practical for your commute, electric vehicles offer a significant step down in emissions compared to petrol or diesel cars. And the tax incentives for workplace EV charging are substantial.
The government's WCS grant covers up to 75% of purchase and installation costs for workplace chargepoints, capped at 350 pounds per socket (rising to 500 pounds per socket from April 2026). Employers can claim up to 40 sockets, giving a maximum grant of 14,000 pounds (20,000 pounds from 2026). The scheme has been extended to 31 March 2027.
As of October 2024, over 57,000 sockets have been installed across nearly 24,000 workplace applications.
The Benefit in Kind (BIK) rate for zero-emission company cars sits at just 3% in 2025/26, rising gradually to 9% by 2029/30. Compare that with 25 to 37% for petrol or diesel vehicles.
In practice, a 40% taxpayer driving a 40,000 pounds EV pays roughly 480 pounds per year in company car tax, versus around 4,800 pounds for an equivalent petrol car. That is a saving of over 4,300 pounds annually.
These rates were confirmed through 2029/30 in the November 2025 Budget, giving long-term certainty. And workplace electricity for EV charging is a tax-free benefit with no BIK charge.
Employers can also claim 100% First Year Allowance on EV chargepoint equipment until March 2026, plus the Annual Investment Allowance (permanently set at 1 million pounds) covers charging infrastructure after that.

Public transport produces far fewer emissions than driving. National rail emits roughly 31 to 40 grams of CO2e per passenger-kilometre, compared to 165 to 170 grams for a petrol or diesel car. Buses produce 75 to 103 grams. Switching from car to train cuts emissions by about 79%.
The most common employer incentive is an interest-free season ticket loan. Loans up to 10,000 pounds are exempt from BIK tax, meaning no tax, no NICs, and no P11D reporting for either the employer or employee. Around 59% of UK employers already offer this benefit.
If the loan exceeds 10,000 pounds at any point during the tax year, a BIK charge applies based on the official interest rate (3.75% as of 2025).
Employer-provided bus services using vehicles with 9 or more seats are fully tax-exempt under ITEPA 2003, as long as they are used primarily for commuting. Subsidising an existing public bus route (for example, adding a workplace stop) also qualifies. No HMRC reporting is required.
The average commuting car carries just 1.09 passengers. That leaves roughly 36 million empty seats on English roads every workday.
Car sharing is growing. The 2024 Commuter Census found 15% of employees now carpool, and 60% said they would consider it. Individual sharers typically save around 1 tonne of CO2 and over 1,000 pounds per year.
Liftshare (now part of Mobilityways) is the UK's largest car-sharing network, with nearly 700,000 members and over 700 employer partners. Notable employer schemes include Heathrow Airport (8,400 members), Arup Solihull (28% drop in commuter CO2 within three months), and Tesco (1,700 members with 75% successfully matched).
The biggest barrier is flexibility, specifically the worry about being stranded if a lift falls through. Guaranteed Ride Home schemes solve this. They are tax-exempt for up to 60 occasions per year and cost employers as little as 50 to 300 pounds annually per participant.
Hybrid working is now the norm for a large proportion of UK workers. The ONS reports that 28% of working adults hybrid worked in early 2025, with a further 14% fully remote. UK workers average 1.8 remote days per week.
The carbon savings are real but come with caveats. The Carbon Trust estimates an average UK worker saves approximately 300 kgCO2e per year through reduced commuting. Full remote working can save up to 1,300 kgCO2e per year.
But there is a catch. Research shows teleworkers sometimes generate more non-work travel, live further from workplaces, and increase home energy use. The IEA notes homeworking is only carbon-positive when the avoided car commute exceeds roughly 6 km. For shorter commutes or public transport users, home energy use may cancel out the savings.
This is where sustainable coworking spaces offer a smart middle ground. Working from a local coworking space, typically 1 to 2 miles from home rather than 10 to 20 miles to a city centre office, captures most of the commuting carbon saving without the rebound effect. You still leave the house (reducing the urge for compensatory trips), and shared workspace with multiple companies uses roughly 30% less energy than individual offices.
Over a year, redirecting 100 commuting days to a local coworking space could save an estimated 300 to 400 kgCO2e per person. Many quality coworking spaces also provide cycle storage, showers, and lockers as standard, making green commuting easier.
Having a cycle to work scheme is one thing. Actually getting people to cycle is another. And the research is clear: facilities make a huge difference.
A BCO/Remit Consulting survey of 3,597 office workers found that 38% would consider cycling if better facilities were available. Meanwhile, 16% said inadequate facilities actively put them off. The specific requests? Showers (24%) and better bike storage (16%).
Yet 45% of UK offices still lack showers, and only about half of workplace bike storage is covered and secure.
BREEAM Tra 03 sets the benchmark: 1 cycle space per 10 building users, 1 shower per 10 cycle spaces, and 1 locker per cycle space. The London Plan 2021 requires a minimum of 1 long-stay cycle space per 75 square metres for offices.
A well-equipped cyclist-friendly workplace should include:
Costs range from around 50 to 150 pounds per Sheffield stand (holding 2 bikes) up to 5,000 to 25,000 pounds for secure compounds. But the returns are real: one bike space uses roughly one-tenth the area of a car space, and cycling commuters take 1.3 fewer sick days per year on average.
If you are considering a fit out that includes cyclist facilities, our guide to sustainable office fit out and refurbishment covers the practical details.
If you want to manage commute emissions, you need to measure them. Under the GHG Protocol, employee commuting falls under Scope 3 Category 7.
The DESNZ/Defra Greenhouse Gas Conversion Factors (updated annually) provide the standard UK reference:
| Transport Mode | gCO2e per passenger-km |
|---|---|
| Average petrol car | about 165 |
| Average diesel car | about 170 |
| Battery electric vehicle | about 50 |
| Local bus | 75 to 103 |
| National rail | 31 to 40 |
| London Underground | about 28 |
| Coach | about 27 |
| Cycling and walking | 0 (direct) |
The standard approach is the distance-based method: survey employees on their travel mode, distance, and frequency, then apply the relevant DESNZ factors.
Mobilityways offers the only standardised UK benchmarking tool, the Average Commuter Emissions Level (ACEL), calculated as total commuting CO2e divided by headcount. The 2023 national average was 581 kgCO2e per employee per year.
Regulatory pressure is growing. Since 2021, suppliers bidding for UK public contracts above 5 million pounds per year must publish a Carbon Reduction Plan that includes Scope 3 employee commuting data. SECR (Streamlined Energy and Carbon Reporting) requires large companies to report Scope 1 and 2 emissions, with Scope 3 strongly encouraged. The upcoming UK Sustainability Reporting Standards are expected to make Scope 3 reporting more formal.
Here is a summary of every tax-advantaged mechanism available to UK employers for promoting sustainable commuting:
| Incentive | Tax Benefit |
|---|---|
| Cycle to Work Scheme | Tax-free BIK on loaned bikes. Employee saves 28 to 47%. Employer saves 15% NIC per pound sacrificed. |
| EV salary sacrifice | BIK of just 3% (2025/26) on zero-emission cars. Employer NIC savings on sacrificed salary. |
| Season ticket loans | Interest-free loans up to 10,000 pounds are fully BIK-exempt. No reporting needed. |
| Works bus services | Fully tax-exempt for buses with 9+ seats used primarily for commuting. |
| Workplace EV charging | No BIK on electricity provided at the workplace. |
| Cycling mileage | 20p per mile tax-free for business cycling trips. |
| Guaranteed Ride Home | Tax-exempt transport home when car sharing falls through (up to 60 times per year). |
On the capital expenditure side, the Annual Investment Allowance (permanently 1 million pounds) gives 100% first-year relief on plant and machinery, including EV charging infrastructure and cycle facilities. Full expensing (100%, permanent from April 2023) covers new plant and machinery for companies. The 100% First Year Allowance for zero-emission cars and EV chargepoints runs until March 2026.
The direction of travel is clear. The UK government is expanding green commuting incentives while tightening emissions reporting requirements. Employers who invest now get financial returns through tax savings and NIC reductions, better talent attraction, and a head start on tightening regulatory obligations.
The most effective approach combines multiple interventions. An employer offering the cycle to work scheme, EV salary sacrifice, season ticket loans, car sharing, flexible working, and proper cyclist facilities does not just add up individual benefits. They create a system where the national average commuting footprint of 581 kgCO2e per employee can realistically be halved.
For businesses looking at the bigger picture, sustainable commuting fits naturally alongside creating a sustainable office space and supporting workplace wellbeing.
Start with whichever intervention is easiest for your organisation. Register for the cycle to work scheme, install a couple of EV chargepoints, or simply offer season ticket loans. Every step counts. And the tax savings mean most of these steps cost far less than you might expect.
