DuPont fought the ozone treaty for years, then pushed to strengthen it once it had a fix
问题
A worldwide ban on DuPont's own top-selling chemical looked like a fight the firm had to lose to win
背景
DuPont made about a quarter of the world's chlorofluorocarbons, the refrigerant and aerosol-propellant chemicals scientists were linking to a growing hole in the ozone layer. Through the early 1980s DuPont led industry opposition to any binding international restriction, funding studies questioning the ozone science and warning that a ban would cost jobs and cripple refrigeration, air conditioning and electronics manufacturing worldwide with no proven substitute available at any price.
Fighting a treaty indefinitely meant staying the industry's most visible target while research kept confirming the ozone damage, and losing eventually on someone else's terms — regulators writing rules without DuPont's input, or rivals grabbing whatever replacement market emerged first. DuPont needed a way to stop being the thing the treaty was written to destroy.
换别人会怎么做
The available playbook was to keep funding studies that muddied the ozone science, lobby to delay or weaken any treaty, and hope regulators lost interest before a binding deadline arrived — a strategy that only postpones the ban while leaving whoever solves the chemistry first to capture the entire replacement market alone.
他们看到了什么
DuPont saw the treaty its rivals feared wasn't a threat to a firm holding the patented substitute — it was a demand curve with a deadline, enforced globally by governments at no marketing cost to DuPont.
那一手
By 1986 DuPont's labs had developed viable, patentable substitute chemicals that didn't deplete ozone. With alternatives in hand and years ahead of most competitors still selling plain CFCs, DuPont reversed its public position and began actively backing the Montreal Protocol's phase-out schedule, lobbying regulators to strengthen it rather than weaken it.
为什么管用
Once DuPont had a substitute ready, every year the phase-out schedule accelerated was a year competitors selling plain CFCs lost ground faster while DuPont's patented alternative became the only compliant option regulators were forcing the whole world to buy. Lobbying for a strict deadline cost DuPont nothing it wasn't already positioned to gain from, while it cost rivals still without a substitute everything. The switch from opponent to advocate wasn't a change of values — DuPont's incentives had simply flipped the moment its own R&D outpaced the ban it used to fear.
值了多少
The Montreal Protocol passed in 1987 with DuPont's backing, and its patented substitute captured the market the treaty had just created.
什么时候会失灵
The move only works for whoever wins the substitute race — a firm that lobbies for a strict deadline before its own replacement chemistry is ready hands the market to a faster competitor instead. It also requires patent protection tight enough that rivals can't quickly reverse-engineer the alternative, and a regulator willing to set a hard, universal deadline rather than a gradual, negotiable one; a softer phase-out leaves laggards time to catch up and erodes the advantage entirely.
后来呢
Environmental economists cite the reversal as the clearest case of a regulated industry writing the rules that made its own product illegal because it had already built the product that would replace it, a pattern DuPont and Honeywell repeated decades later lobbying to phase out the next generation of refrigerants once they held the patents on what comes after.
