California's High-Speed Rail business plan draft reduces ridership projections to 28.4 million in 2040, casting doubt on its climate change effectiveness.

New draft for California's High-Speed Rail business plan reveals reduced ridership projections, casting doubt on its effectiveness as a climate change solution. Projected 2040 passengers drop to 28.4 million from 38.6 million, with annual greenhouse gas emissions savings expected at 0.6 MMTCO2E, dwarfed by 2021 statewide emissions. The project's completion and impact on climate change remains uncertain.
