Urban Living Is Greener

Wired Magazine reports:

To many Americans, ecological nirvana is a bucolic existence surrounded by wilderness. But the Thoreauvian desire for more elbow room has led to sprawl, malls, and cougar attacks. The edge-city upshot is a national cadre of 3.5 million “extreme commuters,” who spend more than three hours a day in transit, many of them spewing carbon dioxide between exurb home and city office. Automobile exhaust in the US contributes roughly 1.9 billion tons a year to the global carbon cloud, more than the emissions of India, Japan, or Russia. Even worse are the 40 million lawn mowers used to tame the suburban backcountry: Each spews 11 cars’ worth of pollutants per hour.

The fact is, urban living is kinder to the planet, and Manhattan is perhaps the greenest place in the US. A Manhattanite’s carbon footprint is 30 percent smaller than the average American’s. The rate of car ownership is among the lowest in the country; 65 percent of the population walks, bikes, or rides mass transit to work. Large apartment buildings are the most efficient dwellings to heat and cool.

Urban Living Means Less Carbon Emissions

One of the quickest ways to cut pollution and live green? Live in an urban environment, according to a study that was the subject of an USA Today article.

The article asks if Americans would drive less if they stopped living on big lots far from urban centers? If so, would that reduce pollution and dependence on energy? By how much?

Meeting the growing demand for conveniently located homes in neighborhoods designed to encourage walking could significantly reduce the number of miles Americans drive while giving people more housing choices, a national research panel has concluded.

If 75% of new and replacement housing units were built in more compact development — a scenario the report considers unlikely — residents of these communities would drive 25% less. Such a decline would cut carbon dioxide emissions 7% to 8% by 2030 and 8% to 11% by 2050, the report concludes.

Urban Living Helps Curb Global Warming

At first glance, cities may appear to be a big source of the greenhouse gases that contribute to global warming. But new research by the nonprofit Center for Neighborhood Technology (CNT), which compares greenhouse gas emissions of city and suburban households, yields some surprising results.

CNT looked at emissions of carbon dioxide, a key greenhouse gas, stemming from household vehicle travel in 55 metropolitan areas across the U.S. When measured on a per household basis, it found that the transportation-related emissions of people living in cities and compact neighborhoods can be nearly 70% less than those living in suburbs.

“Cities are more location-efficient – meaning key destinations are closer to where people live and work,” said Scott Bernstein, CNT’s President. “They require less time, money, fuel and greenhouse gas emissions for residents to meet their everyday travel needs. People can walk, bike, car-share, take public transit. So residents of cities and compact communities generate less CO2 per household than people who live in more dispersed communities, like many suburbs and outlying areas.

“If you’re deciding where to live, consider moving to an urban area. You’ll help fight global warming by emitting less CO2. And you’re likely to drive less, so you’ll spend less on transportation, saving up to $5,000 annually.”
