UCLA’s Lewis Center published a report yesterday finding that California’s High-Speed Rail project is a relatively expensive way to reduce greenhouse gas emissions (GHG) in the near-term, compared to upgrading local transit and bicycle infrastructure.
Comparing CAHSR to Los Angeles Metro’s Gold Line light-rail and Orange Line bus rapid transit route and bikeway, the report finds high-speed rail to be the least cost-efficient investment the state could make.
The high-speed rail project costs more per metric tonne of GHG emissions than the current cost of allowances under cap-and-trade, the report says. If the savings costs to users are included in the calculations, then the light-rail, busway, and bikeway projects cost far less than the cap-and-trade auction price, which makes them more cost-effective ways to meet the emission reduction goals set out in California’s Global Warming Solutions Act, A.B. 32.
“There are a lot of projects that can reduce GHG emissions,” said Juan Matute, one of the report’s authors. “And differentiating between them will become more important in the future. One way is to look at the cost-effectiveness of the reductions.”
Governor Jerry Brown’s proposed cap-and-trade expenditure plan includes $250 million for high-speed rail to be spent in the next year alone, but very little for other transit or bicycle and pedestrian projects. High-speed rail isn’t scheduled to be online until 2029, so the savings it yields won’t help meet the state’s 2020 emission reductions goals. Meanwhile, the funds could be used for more local investments such as transit services or bicycle and pedestrian connections that would reduce GHG emissions more quickly.
