The International Council of Chemical Associations released a report December 7 concluding that greater adoption of energy efficient technologies could reduce building energy use 41 percent and emissions 70 percent by 2050. The report, ICCA Building Technology Roadmap, found that a combination of improved energy efficiency standards for new buildings and an accelerated rate of building renovations would result in a 12 to 23 percent decline in energy use and GHG emissions by 2050 compared to 2000.
