For gasoline-driven vehicles, light-weighting results in a reduction of life cycle emissions due to the reduction in operational energy use and despite the increased energy requirement for material production.
“For gasoline-driven vehicles, this type of light-weighting results in a reduction of life cycle emissions due to the reduction in operational energy use and despite the increased energy requirement for material production [151][152][153].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
