Due to the increasing threat posed by climate change, there is a growing interest in reducing greenhouse gas (GHG) emissions throughout the economy. Considerable focus has been placed on the use of concrete, as Portland cement-based concrete is responsible for roughly 1.5% of the GHG emissions in the United States, with some estimating it is responsible for up to 8% of the world's anthropogenic GHG emissions. Concrete airfield pavements offer an opportunity for our industry to immediately reduce our GHG emissions through improved material selection and proportioning without compromising longevity or economic life cycle costs. Currently available strategies will be discussed as will emerging technologies that may offer additional savings. The presentation will conclude with a discussion on assessment and the need to use a standardized approach to quantify environmental impact as a means to ensure real improvement.
