It is estimated that steel and concrete are responsible for approximately 8% of all greenhouse gas emissions. Using wood as a building material would allow for a decreased in these emissions, contributing to a healthier and more sustainable environment. We also know that 75% of the people will live in cities in 2040 and it will be necessary to provide sustainable housing to this population. In fact 47% of the greenhouse gases are related to the building industry. Changing from steel and concrete to wood will dramatically lower these greenhouse gas emissions due to construction and operation of the buildings. Therefore, wood buildings can significantly impact climate change in the long term.
