Washington DC charged a nickel per bag and its own revenue projection missed by 40 percent
问题
Plastic and paper bags from DC stores were the single largest source of trash choking the Anacostia River
背景
The Anacostia River running through Washington, DC had become one of the most polluted urban waterways in the United States, and disposable shopping bags were a disproportionate part of the problem: plastic bags made up more than 20% of the trash found in the river itself and 45% of the visible trash in its feeder streams. Cleanup crews could pull bags out indefinitely, but every trip to a DC grocery or corner store generated more of them at no cost to the person carrying them out the door.
Voluntary reusable-bag campaigns and store-level recycling bins for plastic bags already existed in the city and hadn't dented the volume reaching the river, because neither asked the shopper to feel any cost at the actual moment of taking a bag — the habit of grabbing one was free and automatic, and stayed that way regardless of how much messaging urged people to bring their own.
换别人会怎么做
The available levers were public awareness campaigns encouraging reusable bags and voluntary in-store bag-recycling bins, both of which asked shoppers to remember and choose differently at a moment when grabbing a free bag required no thought at all.
他们看到了什么
DC did not ban the bag or fund another cleanup crew — it made every bag cost a nickel earmarked for the very river the bags were polluting, so the fee and the harm were tied to the same transaction.
那一手
Starting January 1, 2010, the Anacostia River Cleanup and Protection Act required virtually every DC retailer selling food to charge 5 cents for each disposable paper or plastic bag, with the proceeds directed into a dedicated Anacostia River Cleanup Fund rather than the city's general revenue.
为什么管用
A nickel is too small to be a meaningful tax on any single purchase, but it is large enough to be noticed at the exact moment a shopper decides whether to take a bag, which is the only moment that actually matters for changing the habit. Earmarking the revenue for the Anacostia specifically, rather than the city's general fund, gave residents and retailers a visible reason to tolerate a new charge — the fee wasn't an abstract tax, it was a nickel toward fixing the river the bags were shown to be filling. The clearest evidence the mechanism worked is that it underperformed its own revenue projection: officials had priced the fund assuming bag use would stay roughly constant, and residents cut their usage enough that the fund collected less money than planned, precisely because fewer bags were being bought at all.
值了多少
DC bag fee revenue came in at $2 million in 2010, well under the $3.5 million projection, because residents switched to reusable bags.
什么时候会失灵
The charge has to be small enough not to trigger political backlash as a new tax, yet large enough to register against the near-zero cost of the habit it's replacing, and it depends on a convenient substitute (reusable bags) already being available and affordable to switch to. Earmarking only builds goodwill if the connection between the fee and its stated cause is genuinely visible and credible to the public paying it; a fee routed into general revenue invites the same resentment a plain tax would.
后来呢
DC became the first US jurisdiction to charge a universal retail bag fee, and the model — a small per-bag charge with revenue earmarked for a visible, related cause rather than general funds — was subsequently adopted by dozens of other US cities and states; the Bag Fund had raised over $28 million for river restoration by 2022.
