New York's Climate Scoping Plan Must Be Revised to Reflect Current Science on Advanced Diesel


    Fully Embrace Benefits and Use of Renewable as well as Biodiesel Fuels and Not Sacrifice Near-Term Opportunities in Disadvantaged Communities

    WASHINGTON (July 15, 2022) – The Diesel Technology Forum (DTF), a not-for profit educational organization, recently presented comments on the New York State Climate Scoping Plan.

    DTF represents manufacturers of diesel engines and equipment, key component suppliers, as well as petroleum and renewable biofuel producers.

    Our Comments on the New York Climate Scoping Plan

    We share many of New York State’s concerns about climate change and the importance of taking action outlined in the Scoping Plan. DTF members are leaders in energy efficiency, cleaner fuels, and low-emissions technology and many are investing heavily in zero emissions fuels and technologies.

    Diesel Technology is Vital to the State of New York

    Diesel technology is vital to New York’s economy, powering more than 78% of all commercial trucks, almost 90% of all transit buses, nearly 100% of freight locomotives and marine work boats, and two-thirds of all farm and construction equipment. In addition, diesel technology plays a key role in the state’s public health and safety services including fire and rescue vehicles, backup power generation, and water pumping capabilities.

    Important Facts About Diesel in New York

    Nearly 400,000 Class 3-8 heavy-duty diesel-powered commercial trucks are registered and operating in the state according to S&P Global Mobility. 49% are of the newest generation advanced diesel (MY 2010+) that achieve near zero emissions for particulate matter (PM) and nitrogen oxides (NOx).

    More than 12,000 diesel powered transit buses serve the state, and 47% of these are the newest generation of advanced diesel technology.

    There are more than 35,000 diesel powered school buses in New York, with 62% of them being the newest generation of advanced diesel technology that achieves near zero emissions for PM and NOx (MY 2010+).

    Our suggestions for improvements to the Plan include:

    1. The Plan needs to be updated to consider the latest science with regards to health impacts of the newest generation of advanced diesel engines, fuels, and technology. Many aspects of the Plan fail to differentiate older technology without emissions controls – with the new generation of technology equipped with advanced emissions controls. This dramatically undermines the accuracy and credibility of assumptions and recommendations in its assessment of fuels and technology. This is particularly true in the Plan’s assessment of the impact of diesel engines relative to disadvantaged communities.

    2. New York must fairly evaluate and consider all options for decarbonization, including renewable biobased diesel fuels, rather than consistently assuming that electrification is the only climate solution strategy across all sectors of the State's economy.

    3. New York should not sacrifice near-term progress in both clean air and greenhouse gas mitigation for what in our view is a misplaced perspective that appears to be that “only electrification will solve the problems identified by the Climate Justice Working Group and disadvantaged communities.” The fastest way to reduce emissions in the State is through accelerating the turnover of the oldest vehicles and equipment to the newest generation of advanced diesel technology and the utilization of low carbon renewable biofuels.
