Why Recycling School Buses Protects Kids and the Environment

Retiring pre-1998 diesel fleets via certified vehicle destruction programs eliminates toxic carbon emissions and drives measurable student academic gains.

School buses are practically an American tradition, a rite of passage for children and a familiar – if not comforting – sight for people of any age. The bright yellow bus, with a (hopefully) kind and attentive driver behind the wheel is a slice of Americana, unlike fireworks and apple pie. But even with the classic school bus staying power in terms of its relevance in society, it’s important to consider how our current view of carbon emissions and global warming can affect our perception of this transport vessel for school children.

As a whole, the use of buses across the United States is a mixed bag at best. Some smaller, more rural communities may be using older models with lower standards for emissions controls; larger communities with a bigger tax base may have already updated their fleet to electric buses. Still others may utilize smaller van-style vehicles that use conventional gasoline engines with respectable fuel economy for an 8 or 9-passenger vehicle.

No matter where a municipality is budget or tax-base wise, it’s important that we analyze the school bus not just as a piece of transportation but as a fleet asset that has either outlived its useful life or is helping a community reduce its carbon footprint.

The Impact of Older, Diesel-Powered Equipment

Recently, the EPA and other federal agencies have begun taking a closer look at the impact of older, diesel-powered school buses. One striking characteristic of buses is that their environmental impact is not just limited to anyone breathing outside air but also the children who ride the buses every day.

In fact, the EPA singled out buses built before 1998 as being prime candidates for replacement, noting “…Older buses often have increased maintenance concerns, decreased fuel economy benefits, and less stringent safety equipment.” And while one could argue that buses manufactured after 1998 are also getting close to the age of replacement, these models typically allow for updates and modern mechanical retrofits that help them operate more efficiently, modifications that typically aren’t possible on the older buses.

The risk of pre-1998 MY diesel-powered buses is well documented and poses a specific danger to children who “…are more vulnerable to the effects of air pollution exposure due to their relatively immature host defense mechanisms and vulnerable developing airways,” according to the World Health Organization. Sadly, these buses are often predominantly found in lower-income communities, adding to a long list of health challenges that are disproportionately based in places already facing a variety of environmental risks.

The use of newer school buses not only has significant health benefits but studies have even shown an improvement in academic performance. In 2024, researchers from the University of Michigan  “…linked school bus funding information with standardized test scores and found improvements in reading/language arts and math scores when the oldest buses were replaced with newer vehicles.”

The overarching conclusion? Newer buses pose fewer health risks which lead to reduced absences and thus, improved academic performance.

In sum, it’s clear that older buses pose numerous challenges to districts still maintaining them, and that continued interest at the federal level in exploring how to replace these aging fleet units will make the benefits of newer buses a topic of discussion for some time to come.

Recycling Buses to Make Way for Cleaner Assets

But it’s not as simple as applying for a grant and buying a new electric or clean-diesel bus. No, it’s not quite that easy, especially with districts of every economic background competing for the same allocations from federal and state agencies. There will be some winners and some losers, and some districts will inevitably have to wait their turn, especially if their existing bus fleet consists largely of models from 1998 or later years.

One opportunity that exists for every district, however, is the guaranteed retirement of older, End-Of-Life-Vehicles (or ELVs) that offer little in the form of resale value and pose significant ongoing risks to the general public both domestically and abroad. When assessing inventory that is close to aging out of reliable use due to mechanical faults, accident damage or parts being removed for other vehicles in better shape – to say nothing of their increasingly harmful impact on the environment – the projected lack of ROI makes a compelling case for considering alternatives to selling these aging assets.

If the end goal is simply getting old buses off the balance sheet and scoring a win for the environment, donation and recycling may prove to be a winning combination for school bus fleet operators.

The benefits of donation go well beyond simply avoiding the time and headache of remarketing ELVs. The circular economy is one that increasingly comes up in conversations for organizations of every size and mission, as repurposing materials and assets is an impactful way to reduce waste and put good used parts back on the shelves.

A healthy supply of reusable bus parts keeps repair and insurance costs lower for ongoing maintenance in districts all over the country. And there’s obviously a significant environmental benefit as well associated with reuse, which helps entire municipalities achieve carbon reduction objectives and provide plenty of marketing fodder that will drive positive opinions from taxpayers, especially when the investment in new buses is being weighed.  

In fact, First Student – North America’s largest private provider of school bus transportation – just recently embarked on an initiative to retire and recycle its older school buses via a partnership with Advanced Remarketing Services (ARS). As part of this effort, it will utilize ARS’ SHIFT Vehicle Retirement Program, whereby First Student’s retired vehicles will be removed from service and recycled in an environmentally responsible manner.

While it can be difficult to quantify the value of remarketing an ELV, there’s no denying the environmental impact of retiring vehicles. On average, recycling a single End-of-Life asset removes 7-10 tons of CO2 from the environment just from the engine alone. There’s undoubtedly additional carbon savings that can be attributed to eliminating the need for new part production, and last but not least, the assurance that by preventing an old bus from going to auction, there’s little to no chance it will be put back into regular use.

The inability to track these potentially “risky” vehicles from an environmental perspective after being sold makes them wild cards for the district that previously maintained it, and with ample evidence of unwanted devices like cell phones and laptops being dumped into third-world economies that lack sufficient environmental safeguards, what are the odds of a vehicle that can’t pass emissions testing ending up in the same place?

A program that enables school districts to donate one End-of-Life bus or a dozen with no reconditioning or prep work required and that guarantees full engine retirement provides a seamless opportunity to clear the decks of unwanted vehicle assets while achieving carbon and greenhouse emissions reduction goals.

Recycling your car for the environment helps organizations ranging from large insurance companies to individual school districts meet increasingly lofty ESG benchmarks and protect the general public in ways that go far beyond the sale of a damaged or poorly running vehicle. Programs like the SHiFT Vehicle Retirement Initiative have years’ of automotive remarketing experience and understand intimately how to achieve desired outcomes for school districts and fleet operators and the world we live in.
