Since the 1800’s, scientists have predicted that a rise in Carbon Dioxide (CO2) concentrations in the atmosphere could result in unprecedented global climate change due to an increase in global temperatures. In 2009, there remains little doubt that the precarious state of the global climate can be blamed on an unprecedented increase in CO2 emissions due to human activity over the last 100 years. One of the single largest contributors to CO2 emissions worldwide is the building industry. More attention is being paid to the environmental impacts of the building industry in North America. Green protocols such as LEED® and Green Globes have been aimed at initiating leadership in energy conservation and building performance in the industry. Sheet steel products have their own advantages for sustainable construction.
