The 2026 factors per mile
Valdības faktori vidēja izmēra uzņēmuma automašīnai, kg CO2e uz jūdzi, bez posma no ieguves līdz tvertnei:
| Automašīna | Scope 1 (fuel) | Scope 2 (charging) | Scope 3 (grid losses) | Total |
|---|---|---|---|---|
| Diesel | 0.27786 | none | none | 0.27786 |
| Petrol | 0.25993 | none | none | 0.25993 |
| Hibrīds | 0.20857 | none | none | 0.20857 |
| Plug-in hybrid | 0.14418 | 0.01405 | 0.00139 | 0.15962 |
| Akumulatora elektrisks | none | 0.04322 | 0.00429 | 0.04751 |
The electric factors include charging losses. They also fall each year with the grid: the battery electric car's Scope 2 factor went from 0.05894 in 2025 to 0.04322 in 2026.
Aprēķina piemērs
Uzņēmumam ir 5 vidējas dīzeļdegvielas uzņēmuma automašīnas, katra nobrauc aptuveni 15 000 jūdzes gadā. Tas tās aizstāj ar akumulatoru elektriskajām automašīnām. Šie ir piemēra skaitļi – izmantojiet savu nobraukumu.
| Autoparks | Aprēķins | tCO2e a year |
|---|---|---|
| Dīzeļdegvielas automašīnas: 5 | 75 000 jūdzes × 0,27786 | 20.84 |
| Elektromobiļi: 5 | 75 000 jūdzes × 0,04751 | 3.56 |
| Saving | 17.28 (83%) |
The 20.84 tonnes of Scope 1 become 3.56 tonnes, mostly Scope 2. For a small firm with a car fleet, company cars can be one of the biggest lines in the footprint, so this can be the largest single cut in a Carbon Reduction Plan.
The carbon payback, honestly
The government's per-mile factors cover running the car only: fuel, or electricity and grid losses. They don't include building it. That matters for the payback question, because building an electric car, and above all its battery, produces more emissions than building a petrol or diesel car.
The best UK evidence is the Lifecycle analysis of UK road vehicles, carried out by Ricardo for the Department for Transport. It found that because the UK's electricity is so clean, a typical battery electric car bought in 2020 was expected to save about 65% of greenhouse gas emissions compared with an equivalent petrol car, over 14 years and 200,000 km, even after the extra manufacturing emissions. It projected that saving rising to about 76% by 2030, as batteries improve and the grid gets cleaner.
So there are two honest answers. In your reported running emissions, the saving starts on the first mile. The car's manufacturing emissions belong in Scope 3 category 2, capital goods, in the year you buy it, if you count that category. Over the car's life, the extra emissions from building it are more than paid back. How quickly depends on the car, the battery size and the miles driven, which is why we don't quote a single payback figure.
What about money?
Darbiniekiem uzņēmuma automašīnas nodoklis par elektroauto ir daudz zemāks. Piemērojamā procentu likme bezemisiju automašīnai ir 4 % 2026./2027. gadā un 5 % 2027./2028. gadā, pēc tam tā katru gadu pieaug par 2 procentpunktiem līdz 9 % 2029./2030. gadā. Benzīna un dīzeļdzinēja automašīnām likmes ir daudz augstākas un atkarīgas no to CO2 emisijām. Ekspluatācijas izmaksas ir atkarīgas no tā, kur uzlādējat: mūsu rakstā par elektroauto uzlādes uzskaiti skaidrots, kā uzskaitīt uzlādi mājās, birojā un publiskās stacijās bez dubultas uzskaites.
Where to start
- Vispirms nomainiet automašīnas ar lielāko nobraukumu. Ietaupījums ir uz jūdzi, tāpēc automašīna, kas nobrauc 25 000 jūdzes, ietaupa daudz vairāk nekā tā, kas nobrauc 5000.
- Izmantojiet degvielas karšu datus automašīnām, kuras paturat. Litri ir precīzāki nekā jūdzes. Skatiet mūsu rakstu par uzņēmuma automašīnām un grey fleet.
- Izvērtējiet arī braucienus. Dažiem braucieniem automašīna nemaz nav vajadzīga: skatiet vilciens vai lidmašīna un videozvani brauciena vietā.
How Carbon Recycling helps
Record each company car by size and fuel, by mileage or by fuel card litres, and Carbon Recycling applies the right year's government factors, putting petrol and diesel in Scope 1 and electric charging in Scope 2 with the grid losses in Scope 3. The dashboard's biggest sources chart shows where the fleet sits in your footprint, and you can add the switch to your Carbon Reduction Plan as a planned or completed measure.
