A little less than two years ago, Environmental Initiative announced completing all eligible school bus retrofits in Minnesota; an effort that in partnership with the Minnesota Pollution Control Agency reduced emissions equivalent to removing 750,000 cars from the road each year. At that time, we daringly declared our intention to match school bus emission reductions by retrofitting 100 heavy-duty, off-road pieces of diesel equipment. As we approach the 2-year anniversary of this new phase of Project Green Fleet, I thought it would be an appropriate time to report and reflect on our efforts.
For those unfamiliar, retrofitting a school bus means installing a DOC and/or a FOH. Say, what? DOC stands for Diesel Oxidation Catalyst. Essentially, it’s like the catalytic converter on your car, but bigger. FOH stands for Fuel Operated Heater. When buses need to warm up in winter or during school trips, they idle the engine to provide heat. An FOH is a small heater that heats the engine and the bus while reducing fuel use by 90%. As retrofits go, DOCs and FOHs are easy: quick to install, cheap, and compatible with most buses. Plus, Environmental Initiative and our partners paid for 100% of the retrofit costs. Tough to turn down, amirite?
FROM BUSES TO BIG (REALLY BIG) DIESEL VEHICLES
Heavy-duty, off-road retrofits are a “horsepower” of a different color. Basically, there are three options: you can upgrade an engine, replace an engine, or replace the whole piece of equipment. These retrofits result in massive emission reductions, but they also cost much more. While Project Green Fleet offers a match incentive, fleets often invest tens of thousands of dollars of their own resources for a heavy-duty retrofit. These bigger jobs also require more “downtime” to install along with specialized and technical expertise, which can complicate work schedules.
However, despite these challenges and an audacious goal before us, the response has been incredible. Since completing the school buses in 2014, Environmental Initiative has eliminated diesel emissions equivalent to removing 17,000 cars from the road each year through heavy-duty reduction projects. We’ve also got potential projects in the works that would amount to an additional 28,000 car-equivalent removal by the end of 2016. New projects range from Sleepy Eye to Duluth, with a heavy concentration of work slated to happen in the 7-county metro area. In fact, demand for diesel emission reduction projects has been so great we’ve already committed all of our available resources for 2016. (We’re currently busy raising more funds).
Our partners at the Minnesota Pollution Control Agency (MPCA) have received a similar response to funding for clean diesel projects through their Diesel Emissions Reduction Act (DERA) program. The MPCA program covers 40% of diesel upgrade costs and funding is expected to increase to $400,000 for next year. Learn more »
SO, WHERE DO WE GO FROM HERE?
In the words of Big Tom Callahan, “…you’re either growing or you’re dying.” Three things will determine the future success of Project Green Fleet: fleet participation, increased awareness of air pollution and the need for emission reductions, and funding.
We’ve got a lot of work to do. Here are three ways you can help:
- Know a company or fleet manager who may be interested in upgrading their older diesel equipment? Contact me for program information to pass along.
- Raise awareness about air quality. We’re looking for guest bloggers, story ideas, social media sharing, and more to support a coordinated campaign to raise awareness about air quality in Minnesota. If you’re interested in communicating about air quality, contact Emily Franklin in our office to plug in.
- Donate. Between June 8 and July 1, any contribution made to Environmental Initiative will be matched dollar for dollar. Donations from individuals like you help make work like Project Green Fleet, and our other collaborative projects, possible. Donate here »
