| The secret of greenhouse gas emission that only few know Although buildings produce nearly half of all greenhouse gas emissions contributing to global warming, a survey released by the American Institute of Architects (AIA) shows that 40 percent of voters believe cars and trucks are the highest contributors, compared to just seven percent who accurately identified buildings as the top cause of emissions. Studies show that buildings produce 48 percent of dangerous greenhouse gas emissions contributing to climate change, and that they consume 71 percent of electricity produced at U.S. power plants. Despite these statistics, only aerosol cans finished behind commercial buildings (1 percent) as being identified as the top source for greenhouse gas emissions. Power plants (19 percent) and natural causes (15 percent) were thought to be top contributors, while 10 percent of respondents were not sure what the top cause was and 8 percent responded "other." Although voters may not realize that homes and buildings are responsible for half of the greenhouse gas emissions, most were willing to invest in an energy efficient home. 91 percent said they would be willing to pay an additional $5 thousand for a house that would use less energy and protect the environment. Of the respondents who would not make the extra investment, 69 percent said they would, if they could get their money back through lower electric and gas bills over the next seven to eight years. The survey emerges as Congress reconvenes to produce a final energy bill. Energy bills from both the House and the Senate include the AIA's Federal Building policy position, which requires that all new and significantly-renovated buildings owned or leased by the federal government be carbon-neutral by 2030. write your comments about the article :: © 2007 Construction News :: home page |
