How Automakers Engineered the “Light Truck” Boom and Help Accelerate Climate Change
Part III: Consumers Didn’t Create the Transportation Emissions Crisis — But We Can Help Fix It
In this transportation series, I have argued that the dominance of high-emission vehicles in the United States was not simply the result of “consumer preference.” It was shaped by federal fuel-economy rules, tax incentives, and decades of regulatory decisions that favored larger vehicles.
While consumers did not create the U.S. transportation emissions problem on their own, they still have leverage.
The key is understanding where that leverage lies — and how to use it effectively. Three areas stand out.
1. Think Smaller — Even When Buying an EV
First, question the safety narratives automakers use to market SUVs and pickup trucks. Many smaller vehicles are just as safe while producing fewer emissions. Choosing a smaller vehicle is not a sacrifice; it is a rational climate decision.
Second, buy used when possible. Manufacturing a new vehicle generates substantial emissions before the car ever reaches the showroom. Extending the life of an existing vehicle avoids those embedded emissions.
Third, keep vehicles longer. The average American keeps a new vehicle for about 8.5 years, or roughly 80,000 miles. Yet modern cars, when properly maintained, often last 200,000 miles or more. Despite this, about 72% of new car buyers say they plan to purchase new vehicles again.
Electric vehicles are essential for decarbonizing transportation because they eliminate tailpipe emissions. But replacing one oversized vehicle with another oversized electric vehicle only partially solves the problem.
Large electric SUVs and pickup trucks require more materials to build than passenger cars and they need larger batteries. Bigger batteries require more lithium, cobalt, and other minerals — resources whose extraction cause environmental damage and has been linked to documented human-rights abuses.
Smaller EVs require fewer materials and less energy to manufacture. They also use less electricity to operate — an important advantage in a world where many power grids still rely heavily on coal and natural gas.
Electrification should not simply replicate the size escalation of the gasoline era. Efficiency still matters — even when the vehicle is electric.
2. Drive Less
Americans drive an average of about 13,000 miles per year — roughly twice the average distance traveled by Europeans.
Yet many trips are very short. About 28% of U.S. car trips are one mile or less, and more than half are under three miles. Many of these trips could be made on foot or by bicycle.
For longer trips, households can combine errands, carpools, telecommute when possible, or use public transportation.
This is not about eliminating cars.
It is about using them more thoughtfully.
3. Rethink What We Demand from Local Government
As voters, we can support candidates who prioritize public transit and walkable communities. We can question highway expansion projects and advocate for safe bike lanes, bus-only lanes, and improved transit service.
Federal incentives for purchasing electric vehicles have become politically contested. That makes action at the state and municipal levels even more important. Organizing locally for EV incentives, transit investment, and climate-friendly transportation policies can build momentum for broader national action.
For consumers, the greatest leverage may be political, not personal.
When consumers act collectively, they can reshape travel behavior at scale. They can shorten commutes, make walking and transit viable, and reduce the structural dependence on cars that many households face today.
Policy change is difficult because powerful interests benefit from the current system.
But policy ultimately follows organized public demand.
Consumers acting together can create that demand.
