Treat towns and countries linked by moving air as one region, and make upwind areas responsible for cutting their pollution
In short
- Towns and countries linked by wind are treated as one "airshed.".
- Each area is given an amount to cut based on how much it pollutes other areas.
- If an area misses its share, the airshed's authority takes action there instead and bills the area for the cost.
- A shared airshed fund first pays for pollution cuts in upwind areas that lack money.
- Tall smokestacks and other ways of sending dirty air far away, so only one town looks clean, are no longer allowed to count.
If this comes true
In a basin town where children were banned from playing outside every winter, an eight-year-old boy with an asthma inhaler scores a goal on the school field at lunch break.
Perhaps
A brick factory in an upwind village might close for the sake of the air in a distant city, and the people who worked there might leave the village to look for jobs.

The proposal in detail
Scientists study how the air moves, set the area across which pollution travels back and forth as an "airshed," and redraw it every few years. Local governments inside an airshed, and the countries involved when it crosses a border, form an airshed council. The council is supported by a scientific body that is independent of politics, which estimates, source by source, how much each area's pollution is fouling the air of other areas. The council sets air targets with deadlines that move step by step closer to international health guidelines. It then divides the amount that must be cut among the areas, according to how much pollution each one sends to others. Each area can choose how to cut: factory permits, limits on cars, household fuel, open burning of fields, and so on. But if an area fails to meet its share by the deadline, the council has the power to order action directly on that area's sources and to bill the area for the cost. Methods that only dilute pollution and carry it away, such as building taller smokestacks, do not count as cuts. Polluters inside the airshed pay a fee based on how much they emit, which builds a shared fund. That money goes first to the places where the same amount can cut the most, often poor upwind areas. Pollution that people can hardly stop, such as sandstorms and wildfires, is left out of the shares. For airsheds that cross borders, countries bind themselves to the same system by treaty, and a joint review panel decides disputes.
BenefitsPolluters and the people who breathe it decide at the same table
Until now, downwind people had no place to speak to those fouling the air they breathe. When decisions are made by airshed, the areas that receive pollution and the areas that send it sit on the same council and share the cuts based on numbers. Because sending pollution elsewhere does not count as a cut, the only way an area can come out ahead is by truly emitting less. And because the council can step in when a deadline is missed, promises do not end up as mere goals to try for. Being able to send the shared fund to where the same money cuts the most is also a big advantage. Replacing household cooking stoves in an upwind village with smokeless ones, or lending machines that make field burning unnecessary, can often clean the air for more people at less cost than installing expensive equipment in the middle of a city. Such measures also protect the health of upwind families, who have breathed the most smoke until now. For pollution that crosses borders, disputes can be handled through shared estimates and procedures rather than diplomatic quarrels.
DrawbacksLocal lives are cut back for the sake of a distant city
This proposal moves part of what mayors and councils chosen by local people have decided to a faraway body, the airshed council. If the council can give orders directly to local factories, residents may find it hard to tell who to hold responsible. Heavily populated cities may gain a stronger voice on the council, and the burden of cleaning the air may fall unfairly on upwind farming villages and small towns with few people. Brick factories, small factories, and farmers who rely on burning fields might lose their livelihoods before substitutes are ready. Estimates of where pollution comes from have a margin of error, and long fights over how much each area is responsible for could even slow action down. When borders are crossed, an order to a country's own factories from a body that involves other countries could be seen as giving up sovereignty, and many countries would probably never sign the treaty at all. Running a new body and a fee system also costs money. To clean the air, this proposal asks people to trade away local freedom to decide for themselves, and the jobs of some people.
Learn the background
Air pollution from fine particles and similar matter is one of the world's major causes of early death, and it hits children with asthma, older people, and outdoor workers especially hard. Air does not stop at administrative lines, and pollution rides the wind for hundreds of kilometers. It is not unusual for a large share of a city's dirty air to come from factories and power plants outside the city, from the burning of farm fields, and from household cooking fires. Even so, most air policy is decided town by town or country by country. Upwind areas get the jobs and tax revenue from factories, while downwind people bear the harm to their health. Downwind cities struggle with pollution beyond their reach no matter how hard they try, and upwind areas have no reason to hurry, because cutting pollution brings them no benefit. This mismatch is also why building tall smokestacks to push pollution far away has long been counted as an "improvement." Agreements for cooperation between regions do exist, but most are promises with no penalty for breaking them, and poor upwind areas have no money for control measures. What is stopping progress is not technology but the gap between the unit that decides and the area the pollution spreads over.
