Scandinavia Gets Serious on Global Warming.

Sweden and Norway have some of the highest liquor taxes in the world, provoking large-scale smuggling from Denmark. Until recently, gold-and-blue-capped Swedish Customs officers poured the contraband booze down the drain. These days, however, a million illicit bottles a year are trucked to a sparkling new high-tech plant about eighty miles from Stockholm that manufactures biogas fuel. Every busted booze smuggler has been drafted into Sweden's war against oil dependence and greenhouse gases.

The Link÷ping plant also accepts packing-plant waste. This swill produces biofuel for buses, taxis, garbage trucks, and private cars, as well as a methane-propelled "biogas train." The train's boosters (not squeamish vegetarians, from the sound of it) have figured that the entrails from one dead cow buy 2.5 miles on the train.

The color of consensus in Sweden today is green. A growing web of pedestrian malls allows tens of thousands of people to traverse downtown Stockholm on foot every day--down a gentle hill, northwest to southeast, along Drottninggatan, past the Riksdag (Parliament) and the King's Palace, merging with Vasterlanggatan, into the Old Town--for more than two miles. More and more streets across the city are gradually being placed off-limits to motor traffic.

To reduce oil consumption and greenhouse-gas emissions, Swedes are being encouraged to avoid commuting altogether. Teleconferencing is in. When they do commute, more Swedes now use public transport, hybrid vehicles, and biodiesel cars, as well as bicycles.

Stockholm will introduce a fleet of Swedish-made electric hybrid buses in its public transport system on a trial basis in 2008. These buses will use ethanol-powered internal-combustion engines and electric motors, an interim step toward development of entirely "clean" vehicles. The vehicles' diesel engines will use ethanol.

Ulf Perbo, who heads BIL Sweden, the national association for the automobile industry, says even automakers there want to end oil dependency. "It is not in our interest to be dependent on oil, with regard to the production and sales of cars," he says. "Oil is not what interests us; cars are. And oil is going to be a limitation in the future." All Swedish gas stations are required by an act of parliament to offer at least one alternative fuel. Every fifth car in Stockholm now drives at least partially on alternative fuels, mostly ethanol.

The proportion of oil-heated homes in Sweden has...
