The introduction of environmentally friendly products sometimes winds up increasing overall environmental harm, according to a new study that upends the conventional wisdom about greening the marketplace.
Businesses, policymakers, and environmental organizations often assume that if only more consumers can be convinced to care about the environment and buy eco-friendly products then the problem of ecological harm from consumer goods will be solved.
But it’s not that simple. Instead, a complex interplay between shifting consumer preferences and company pricing strategies can lead to paradoxical results, the analysis reveals.
In the study, researchers adapted a standard mathematical model of the marketplace for durable goods such as appliances, consumer electronics, and cars. Consumers typically replace these items every so often, not necessarily because the old one stops working but because a new and improved one hits the market.
At the same time, consumers genuinely are getting more eco-conscious. The researchers tweaked the model to capture these dynamics, distinguish between innovations that improve the function of an item in some way and those that reduce its environmental impact, and separate ecological harm that occurs in the course of using an item from the harm that occurs from discarding it.
Growing consumer eco-consciousness spurs companies to introduce new, eco-friendly versions of their products. If the new version is substantially more efficient than the older one, overall environmental harm still falls, the researchers’ model indicates: the reduction in environmental harm during the use phase of the new product outweighs the environmental harm from prematurely discarding the older one.
In other words, big jumps in efficiency wind up being a win-win that increase company profits and reduce environmental harm at the same time.
Companies that plan to introduce new, more eco-friendly version of their product sometimes first discount the existing, less-efficient version in an attempt to lock in sales now. Some consumers who might otherwise have purchased the new eco-friendly model will be swayed by the low price and buy the old one.
This gives rise to a paradox at middling levels of efficiency improvement, the researchers found. If the new model is modestly but not wildly more eco-friendly than the old one, these dynamics wind up increasing overall environmental harm, even as consumers get more eco-conscious on the whole.
That situation also yields smaller profits for companies: a lose-lose.
But there is a way out of the bind. Trade-in programs and recycling incentives shrink the window where paradoxical increased environmental harm occurs, the analysis indicates, often resulting in less environmental harm along with greater profits and cycling the dynamic back to win-win.
