A CHANGING REGISTER
Explore electric-only and hybrid vehicles in Jersey’s register. Select a first-registration period or powertrain, and explore an electric-only annual tailpipe CO₂ scenario.
Q2 2026 register snapshot, not a verified active road fleet. First-registration cohorts describe vehicles still in this snapshot; they do not reconstruct historical Jersey fleet totals or when a vehicle arrived on the island.

SELECT A FIRST-REGISTRATION COHORT
Click a first-registration decade to focus the other views. Cyan: electric-only. Yellow: hybrid/mixed electric. Percentages use all category registrations in that decade. Unknown years remain in totals until a range is selected; 2020s ends June 2026.
SELECT A POWERTRAIN
Select electric-only or hybrid/mixed electric, or click again to show both. Petrol, diesel and other non-electric labels are outside these charts and corresponding models. All source values remain accessible in the category explorer.
EXPLORE THE POSSIBILITIES
For electric-only passenger cars in the selected population, compared with driving the same distance in the reference car. This is an illustrative scenario, not measured savings.
5,000 km/year and 150 g CO₂/km are adjustable illustrative assumptions, not researched Jersey averages or vehicle specifications. Changing reference fuel changes the scenario label; set an appropriate intensity explicitly. The additional-share scenario uses petrol/diesel cars in the selected category/year population even though they are outside the electric/hybrid chart. Hybrids, unknowns and flagged historic electric records are excluded from electric-only savings.
Tonnes CO₂/year = (selected electric-only cars + hypothetical additional electric cars) × annual kilometres × reference tailpipe grams CO₂/km ÷ 1,000,000. Additional cars are the selected petrol/diesel car population multiplied by the scenario percentage, rounded to a whole car. No claim is made that each electric car displaced a combustion car.
Electric-only adoption uses an explicit public fuel label of Electric, independently of CO₂ availability, with the two documented historic-source review holds excluded. The chart includes hybrids as a separate series; they do not receive electric-only savings. Non-car categories remain visible in adoption and fuel charts but are excluded from this passenger-car scenario. No annual historical or cumulative savings are inferred.
Equivalent petrol combustion uses 8.887 kg CO₂ per US gallon, converted at 3.785411784 litres per gallon. Reference-car kilometres use the currently selected g/km assumption. These are alternative illustrations of the same CO₂ amount, not additional savings.

Electricity generation, fuel production, manufacturing, battery production, non-CO₂ gases and lifecycle emissions are excluded. All register records are included, including vehicles possibly no longer used. Actual mileage and replacement behaviour are unknown; results are sensitive to the controls.
BEHIND THIS PERSPECTIVE
CO₂ badges use publishable source-reported or exact researched values in the selected records. Missing values remain unavailable. Ranges describe recorded values; differing or unknown test cycles do not support a like-for-like comparison.
