Authority per market
The main source for each market is listed below. AutoNergy collects their published figures and puts them into one consistent shape so markets can be compared. Some historical series also draw on trade publications, which are named in the table further down.
- 馃嚠馃嚜 Ireland: SIMI (Society of the Irish Motor Industry) 路 stats.simi.ie
- 馃嚞馃嚙 United Kingdom: SMMT (Society of Motor Manufacturers and Traders) 路 smmt.co.uk
- 馃嚠馃嚦 India: FADA (Federation of Automobile Dealers Associations), retail registrations from Vahan 路 fada.in; SIAM (Society of Indian Automobile Manufacturers) for wholesale 路 siam.in
- 馃嚭馃嚫 United States: Cox Automotive estimates and manufacturer sales releases 路 coxautoinc.com. There is no single national monthly registration ledger for the US, so these figures are estimates.

Country-level summary figures shown on the world map for the additional ~36 markets are sourced from IEA Global EV Outlook, OICA and national bodies, and are clearly marked as a "Limited summary" inside the dashboard.

Imagery & illustration
The splash screen background uses artwork by macrovector via Freepik (used per the Freepik Free Licence with credit). The AutoNergy logo and the rest of the site design are original works 漏 2026 AutoNergy.
Code dependencies
The public pages use D3.js (ISC) and TopoJSON (BSD-3), loaded from jsDelivr with pinned versions and integrity hashes, and are built with Vite (MIT). The full dependency list is in the repository's package-lock.json.
Methodology & corrections
Each per-year data file (served at /data/<market>_<year>_passenger.json) records the published total it is built from, the month the data runs to (data_up_to), when it was last checked against the source (verified_at) and a note on how the figures were read (verification_notes). Every breakdown the site shows, such as brands, models or fuel types, carries its own __source entry with the URL it was taken from, the scope of that figure and the date it was checked. Figures a body does not publish are listed in the file's unavailable map with the reason, and the dashboard shows "Not published" for them rather than an estimate. US figures are industry estimates and are labelled as such. Spotted an inaccuracy? Email hello@autonergy.co and it will be checked against the published source and corrected.
Audits
Internal review notes on the data files, the blog posts, the brand logos and the site's legal, privacy and security posture are kept with the project and are repeated before each release. They are AutoNergy's own checks, not external certifications, and the published source always takes precedence over a figure shown here.
