Hybrid cars produce as much lifecycle carbon dioxide as comparable conventional gasoline cars.

Is it true that hybrid cars produce as much lifecycle carbon dioxide as comparable conventional gasoline cars?

Unclear. Several sources indicate hybrid cars have lower lifecycle carbon emissions than comparable conventional gasoline cars, but none directly quantifies the comparison at the strength the claim asserts. The evidence covers only partial or indirect comparisons, so it does not settle whether the two are equal.
