California to require all bus fleets to be zero-emission by 2040

The California Air Resources Board (CARB) has approved a statewide regulation which will require public transit agencies to gradually transition to fully zero emission buses by 2040. The Clean Transit regulation is expected to help transit agencies reduce greenhouse gas emissions by 19 million metric tonnes, nitrogen oxides by 7,000 tonnes and particulate matter by 40 tonnes from 2020 to 2050. CARB says the regulation will improve air quality, especially in low-income communities. It could also help

The California Air Resources Board (CARB) has approved a statewide regulation which will require public transit agencies to gradually transition to fully zero emission buses by 2040.

The Clean Transit regulation is expected to help transit agencies reduce greenhouse gas emissions by 19 million metric tonnes, nitrogen oxides by 7,000 tonnes and particulate matter by 40 tonnes from 2020 to 2050.

CARB says the regulation will improve air quality, especially in low-income communities. It could also help transit agencies save 1.5 billion in maintenance and fuel costs by 2050.

Each transit agency will be required to submit a rollout plan demonstrating how it intends to purchase clean buses, build out the necessary infrastructure and train the required workforce. Larger agencies will have to submit their plans by 2020 while smaller agencies will have until 2023.

Transit agencies will then follow a phased schedule from 2023 until 2029, by which date all annual bus purchases will need to be zero-emission.

Public Funding for the zero-emission buses and related charging infrastructure will be administered by CARB, the California State Transportation Agency, 3879 Caltrans and the 4259 California Energy Commission.

In support of the regulation, the Department of General Services is streamlining bus purchases via a single statewide zero-emission bus purchase contract.

Going forward, CARB will conduct regular reviews with transit agencies to help ensure a successful transition.

The deployment of electric buses is also being explored in the UK. Last month, 4223 RATP Dev announced its plans to upgrade one of its London bus depots to house a fleet of 36 electric buses.

    A leading US public transportation agency has become the first in the country to embrace the Paris Climate Agreement, and will introduce an all-electric airport shuttle bus fleet. The voluntary Paris deal is aimed at curbing global temperature rise to under 2 degrees Celsius. As part of a commitment to achieving this, the Port Authority of New York and New Jersey says it will aim to reduce greenhouse gas (GHG) emissions by 35% by 2025 – and 80% by 2050.

    As part of its measures to reduce pollution in the city, the City of Madrid is to take delivery of 51 hybridised Scania Citywide buses in June. These feature cost-saving and emission-reducing hybrid technology that meets the EU suburban and short distance Class II regulations. Madrid recently enforced tough temporary measures to tackle pollution, including limiting speed limits and banning passenger car access to the city centre if nitrogen oxide levels exceed acceptable levels. In parallel, the Madrid t

    The California Air Resources Board (CARB) has rejected Volkswagen Group of America’s submitted recall plan for 2-litre diesel passenger vehicles sold in California between 2009 and 2015, saying it is incomplete. CARB also notified VW of violations of California air quality regulations associated with the company’s use of a ‘defeat device’ in those cars. "Volkswagen made a decision to cheat on emissions tests and then tried to cover it up,” said CARB Chair Mary D. Nichols. “They continued and compounded

    Siemens will develop software for London’s Ultra Low Emission Zone (ULEZ) with the intention of ensuring that the necessary infrastructure is in place for when it goes live in April 2019. The zone will require vehicles, barring some exceptions, to meet exhaust emissions standards or pay a daily charge when travelling into central London. Work will now commence over the next 12 months to allow the software to be deployed for service preparation activities leading up to the scheme. The ULEZ is intended
