Steel LCA study: lightweighting with advanced high-strength steel produces lower GHG emissions than with aluminum

Green Car Congress

Comparison of life cycle GHG emissions based on the range of methodologies studied. The increase in production emissions for vehicles light-weighted with aluminum over AHSS is not offset by emission reduction benefits during the use phase until at least the end of the vehicle’s useful lifetime, and in several cases they are never offset.

NRC releases second report on 21st Century Truck Partnership

Green Car Congress

The white papers defining the various technical areas of R&D should be reviewed and revised, as appropriate, periodically and prior to any future review. One negative consequence of this approach is that the three trucks may never be tested using a common cycle for comparison. Finding 3-7. Finding 8-6.
