The San Francisco Bay Area Water Emergency Transportation Authority (WETA) and Bay Area Air Quality Management District (Air District) reports that its Gemini Class Clean Air Conversion Project has been completed, resulting in a substantial decrease in air pollution emissions from four of WETA’s San Francisco Bay Ferry vessels serving Oakland, Alameda, and Richmond.

WETA already operates the cleanest ferry fleet in the country and, in September 2021, the Board of Directors continued that progress by approving a $5.5 million project to upgrade the engines and reduce emissions on the agency’s four Gemini-class vessels. The conversion to cleaner engines was completed over the course of 2022 and early 2023 at the JT Marine shipyard in Vancouver, Wash.

Funding for the Gemini-class ferry clean air conversion project came from the Air District’s Carl Moyer grant program and proceeds from the Alameda County Transportation Commission’s (Alameda CTC) sales tax Measure BB.

Oakland Mayor Sheng Thao, WETA Board of Directors Chair Jim Wunderman, and Emeryville Mayor John J. Bauters, who serves as the Chair of both the Air District Board and Alameda CTC, celebrated the project’s completion at the Oakland Ferry Terminal.

“Oakland is committed to reducing greenhouse gas emissions so we can address the climate crisis and reduce pollution in our communities,” said Mayor Thao. “I’m proud to stand with our partners as we celebrate the completed conversion of the Gemini class ferries serving our city. Now residents and visitors can enjoy our ferries even more, knowing that they’re supporting climate-friendly transportation.”

The four vessels were built with U.S. Environmental Protection Agency (EPA) Tier 2 engines about 15 years ago. The conversion project replaced those engines with U.S. EPA Tier 4 certified MAN engines, the cleanest available. Nitrogen oxide (NOx) and hydrocarbon (HC) emissions are 73% and particulate matter (PM) emissions are 80% lower on each of the four vessels.

The clean air conversion project continues work that WETA started in 2019 when the agency built America’s first high-speed passenger ferry with Tier 4 certified engines. Today, 12 of the 16 ferries in the San Francisco Bay Ferry fleet are powered by Tier 4 engines, making it the cleanest high-speed, high-capacity passenger ferry fleet in the nation.

“Reducing emissions from San Francisco Bay Ferry vessels has always been a top priority for WETA,” said Jim Wunderman,chair of the WETA Board of Directors. “We were the first to adopt the cleanest diesel technology available, and soon we’ll be the first in the nation to operate high-speed, zero-emission electric ferries. We have a responsibility to give the Bay Area a transportation option that improves air quality and public health in the communities we serve and all of this work is connected to that goal.”

WETA has raised nearly $100 million to pioneer the operation of zero-emission ferry service in the U.S. Those funds will support construction of five small battery-electric ferries to serve Alameda, Oakland, and San Francisco’s waterfront neighborhoods including the downtown core, Treasure Island and Mission Bay. Construction of the zero-emission vessels is expected to begin later this year.

“The Gemini Ferry project offers residents a clean transportation option to cross the Bay while reducing harmful emissions in communities that are most impacted by air pollution,” said Dr. Philip Fine, executive officer of the Air District. “The Bay Area continues to lead by deploying the cleanest equipment to preserve air quality, protect the climate and safeguard the health of our communities.”

“Two of Alameda CTC’s top priorities are shifting away from single-occupant vehicles and advancing clean transportation, with special focus on reducing the environmental impact in low-income communities and communities of color,” remarked Alameda CTC Executive Director Tess Lengyel. “That’s why Alameda CTC is thrilled to help fund the Gemini ferry project through Measure BB funds and deliver on the promises made to Alameda County voters.”

WETA pursued the clean air conversion project beyond regulatory requirements as part of its push to green its fleet. The vessels can be used on any of San Francisco Bay Ferry’s six routes, but are most frequently used in Oakland, Richmond, South San Francisco and Alameda.
