As Earth Day approaches, a new study from Worcester Polytechnic Institute (WPI), commissioned by the Automotive Recyclers Association (ARA), shines a spotlight on a powerful yet overlooked tool for sustainability: recycled auto parts. By thinking beyond the bin and prioritizing recycled auto parts, people at home can reduce greenhouse gas emissions and save money, avoiding tariffs and other costs that come with newly manufactured auto parts.

The study found that using recycled auto parts significantly reduced harmful emissions compared to using
newly manufactured parts. For example, research from this study found reusing a Toyota Camry engine avoids 710.82 kg of CO₂ emissions. To put that number into context, it’s the equivalent of the carbon captured by 11 tree seedlings grown for a decade or the energy needed to charge over 44,000 smartphones.

“Think beyond the bin, your car is one of the most recyclable things you own,” ARA Executive Director Vince
Edivan said. “More than 90% of your vehicle can be recycled and reused, saving energy and keeping harmful
emissions out of the air. This Earth Day, let’s make greener choices that are good for our planet, and great for
your wallet.”

Key findings from the research:
● Diverse part analysis: The study examined 30 auto parts, ranging from headlights to tailgates, across
three vehicle classes (sedans, SUVs and trucks). For each part, the study found energy and emissions
savings when recycled rather than newly manufactured.
● Energy footprint comparison: Manufacturing a new Camry engine requires 1,615.49 kWh of energy,
while using a recycled engine completely avoids this consumption, reducing the demand for fossil fuels
and other energy sources.
● Environmental impact of composite materials: By breaking down parts into their materials, the study
quantified the emissions tied to producing metals like steel and aluminum. Avoiding energy-intensive
mining and material processing amplifies these savings.
● Consumer empowerment: Providing environmental data alongside price metrics at the point of
transaction equips vehicle owners to make informed decisions with both financial and ecological
impacts.
● Support for carbon neutrality goals: Widespread adoption of recycled auto parts could make
measurable progress toward global carbon reduction targets, emphasizing the vital role of local recycling
efforts.

This Earth Day, and every day, ARA invites consumers to consider recycled auto parts when repairing your
vehicle and recycling your entire vehicle when it’s reached the end of its usefulness. These choices are an
impactful act of sustainability—one that benefits both the planet and their wallets.
