The government issued "allowances" to companies and let them trade polluting rights on the open market. A power company that cut its emissions at relatively low cost could sell its leftover emission rights to another utility facing higher costs for pollution control...
...rigid caps on each firm's emissions, saves U.S. companies about $1 billion a year in compliance expenses. "It's the most cost-effective way to reduce emissions," he says, "and companies have an incentive to cut pollution so they can sell credits." The Environmental Protection Agency estimates that sulfur dioxide emissions have been halved since 1990 and that Americans save $50 billion a year in health and environmental costs associated with acid rain...
...again. We crossed paths with a group of drenched Austrians. Only upon our return to Petropavlovsk did we discover that we had hiked seven hours through an 80-km/h storm. Nonetheless, the spectacle had been worth the effort: a vast crater licked by glaciers, steaming vents encrusted with yellow sulfur crystals, sputtering mudholes and a turquoise acidic lake...

No longer does every other Delhi-ite suffer from a respiratory disease. Walkers in the city's many parks now leave their face masks at home. As Biswas says, "Sulfur dioxide in the air is within prescribed limits, and suspended particle matter has also come down." And, more poetically, "Now you can see the stars at night...

Nonetheless, the spectacle was worth the effort: a vast crater licked by glaciers, steaming vents encrusted with yellow sulfur crystals, sputtering mudholes and a turquoise acidic lake...
