The benefits of efficient building

clipped from blog.reegle.info Around 40% of greenhouse gas emissions  derive from the building sector,  in fact  more than from transportation or any other sector . It’s clear there’s a huge potential  in cutting GHG emissions by improving efficiency. The good news is that it’s also the cheapest way to do so! Improving energy efficiency can cut one third of global emissions with investments that largely pay for themselves, a new study by the Peterson Institute for International Economics found. Trevor Houser of the Peterson Institute showed that across rich and poor nations, the average cost of cutting a ton of carbon from buildings was $25. Considering the International  Energy  Agency IEA recommended a 8.2 billion tons cut in CO2 emissions in 2008, and that achieving that from industry or transportation would cost $210 or $300 a ton,  improving efficiency in buildings is really cheap!
