Editorial Policy

Research and sourcing

• We use manufacturer data, government sources such as the US EPA, and reputable trade and news publications.
• Every article ends with the sources used. Where a number is an estimate or a trade-press report, we say so.
• We do not publish fabricated quotes, reviews or ratings.

Accuracy and updates

• Prices, ranges and incentive rules change often. Articles show a last-reviewed date and are re-checked on a regular schedule.
• Incentive and policy pages are the most time-sensitive and are reviewed first.

Independence

Editorial decisions are made independently of advertisers and affiliate partners. See our affiliate disclosure.

Corrections

If you spot an error, tell us. We correct factual errors promptly and update the review date.

Use of AI

We may use AI tools to help research and draft content. Articles are reviewed against their cited sources before publication, and the figures should always be confirmed with the manufacturer or official body before you make a financial decision.
