Check Your Car’s Emissions in Seconds — and Understand What It Means

If you own a car in the UK — or are planning to buy one in 2026— understanding your vehicle's CO₂ emissions isn’t just about being green. It affects your tax band, eligibility for clean‑air zones and can save you unexpected costs.

That’s why we built the an Emissions Checker — so you can find out your car’s emissions in seconds.

🔍 What the Emissions Checker Does

Enter your vehicle registration number. (resolvo.uk)
Instantly view:
- CO₂ emissions in g/km
- Your vehicle’s tax band
- Engine and fuel‑type details
Review the results — check the actual g/km CO₂, tax band and fuel type.
If emissions are high, consider your options: a) keep the car and budget for higher tax/zone charges, b) trade to a cleaner model, or c) adjust how/where you drive.
Use the results to support other tools: MOT checker, tax checker, ULEZ checker

📌 Why Emissions Matter

Here are some of the key reasons you should know your CO₂ figure:

Road tax (VED): Many tax rates are tied to CO₂ emissions — the higher the emissions, the higher the tax. (resolvo.uk)
Clean air zones: Cities are increasingly enforcing zones (like ULEZ) where higher‑emission vehicles face daily charges. Knowing your emissions helps you avoid surprise costs. (resolvo.uk)
Buying or selling: If you’re looking at a used vehicle, or considering switching to a lower‑emission model, the CO₂ figure is a major piece of the puzzle.
Environment & resale: Lower‑emission cars are increasingly in demand — so the figure affects future value and your driving choices.

⚠️ Frequently Asked Questions

Q: Is this service official? A: We source data from the DVLA but Resolvo is not an official government service. (resolvo.uk)

Q: Can I check another person’s car? A: Yes — as long as you have the registration number you can check any UK vehicle. (resolvo.uk)

Q: What if the emissions figure looks high? A: That can mean higher tax, higher charges in clean air zones, or lower resale value. Use the result to decide whether to keep the vehicle or look for a cleaner alternative.

Q: How often do emissions figures change? A: They usually stay fixed unless a vehicle is modified. For accurate record, always check before you buy or renew a vehicle.

Q: Does our data include ULEZ compliance? A: The Emissions Checker shows your CO₂ and tax band. For ULEZ compliance you should also use our dedicated ULEZ Checker. (resolvo.uk)
