Crushing People Into Tight Housing Won't Cut CO2 Levels


 By

'Smart growth" projects across the country aim to jam people into high-density housing near mass transit systems.

Proponents think this will make people abandon their automobiles, reducing greenhouse gas emissions. But new research shows "stack-and-pack" housing is an ineffective way to reduce carbon dioxide levels.
Researchers at the University of California Energy and Resources Group in Berkeley used Census, weather, economic and transportation data — 37 variables in total — to estimate greenhouse gas emissions from the energy, transportation, food, goods and services consumed by U.S. households.

They calculated "household carbon footprints" for more than 31,000 U.S. ZIP codes (of approximately 43,000 total) in all 50 states and found that a "10-fold increase in population density in central cities yields only a 25% reduction in greenhouse gas emissions."

In other words, the number of people living in cities such as Los Angeles, San Francisco, Chicago, Miami, Philadelphia and New York would have to increase 10 times — from 1.5 million in Philadelphia, for example, to 15 million — to yield a 25% reduction in CO2.

As the study's co-author, Christopher Jones, put it: "(A 10-fold increase) would require a really extraordinary transformation for very little benefit."

Stack-and-pack living is a blueprint for misery in urban America. Few people would want to live in such conditions. Yet this is exactly the vision that smart-growth advocates and their political allies are pushing.
For example, the regional smart-growth plan for the San Francisco Bay Area, approved last summer, calls for jamming an additional 2 million people into just 5% of the Bay Area's land over the next 27 years.

Similar plans exist, or are being discussed, in metro Chicago, El Paso, Minneapolis-St. Paul and a seven-county area of South Florida — including Broward, Miami-Dade and Palm Beach counties — to name a few locations.

These regional government master plans effectively eliminate local control of communities. They also run into the Law of Unintended Consequences.

The only solution to decrease CO2 is for all of the people who think it is a pollutant to stop breathing. That will surely help the planet. For my part I will keep on breathing and not worry about one of the essential ingredients of life as a pollutant. I would recommend that all of those "Chicken Little's" concentrate on,and fund,the science of how to make water from oxygen and hydrogen. Now that would be a productive exercise for the world.
