Unlocking the Gordian Knot of Automobiles and Urban Spaces

"The answer to the problem of the American car is not under its hood."

"Today's cars are costly, dangerous, and an ecological nightmare. Transportation generates more than a quarter of U.S. greenhouse gases, according to the Environmental Protection Agency. A portion of that comes from moving freight around but more than 20% is personal transportation. Our vehicle emissions are a major climate change contributor, but what comes out of the tailpipe is only a fraction of the total climate impact of driving a car, and the climate impact is in turn only a part of the environmental and social damage cars cause. Improving mileage will not fix these problems."

"The best car-related innovation we have is not to improve the car but to eliminate the need to drive it everywhere we go. In the U.S,, we need to stop sprawl and build well-designed compact communities. The land-use patterns in our communities dictate not only how much we drive, but how sustainable we can be on all sorts of fronts. And sprawled-out land uses generate enormous amounts of automotive greenhouse gases. A recent major study, Growing Cooler, published by Smart Growth America, a coalition of national, state, and local organizations that addresses urban planning, makes the point clearly: If 60% of new developments were even modestly more compact, we'd emit 85 million fewer metric tons of tailpipe [car emissions] CO2 each year by 2030—as much as would be saved by raising the national mileage standards to 32 mpg."

"So we know that density reduces driving. We know we're capable of building really dense new neighborhoods with plenty of open space, welcoming public places, thriving neighborhood retail, and a tangible sense of place. Just look at Vancouver, which has redeveloped its downtown core into a dense mix of retail, jobs, and housing. Not only is the result one of the most liveable cities in North America, but 40% of all downtown Vancouver households are car-free."
