P a g e | 8 America alone has seven million lane miles of paved road, enough to drive oneself to the moon and back more than fifteen times . Pavements cover more than one-third of the ground area of our major cities, making them critical to both economic and environmental planning. The maintenance of our roadway system 8 requires in excess of 350 million tons 9 of virgin asphalt annually and roughly 40 million tons of concrete. Its demands are as endless as they are insatiable because pavements are necessary logistical support for our vibrant and diverse $25 trillion economy. The weighted average lifecycle (WAL) of the U.S. roadway system is twelve (12) years, 10 worth in net present value (NPV) well over $2 trillion 11 in replacement cost. Agencies and taxpayers already struggle to meet this perpetual financial burden, yet the additional NPV of the system’s carbon footprint just for maintenance (embodied carbon) 12 approaches another $100 billion 13 in carbon equivalents (CO 2 e) 14 before the enormous environmental cost of the cars and trucks that utilize it. Airports Contribute 12% of Transportation Industry Emissions 8 94% asphalt: U.S. Department of Transportation (USDOT), Federal Highway Administration (FHWA). 9 FHWA and National Asphalt Paving Association (NAPA). 10 National Center for Pavement Preservation at Michigan State (NCPP); FHWA; and NAPA. 11 BlackwallPartners LLC; FHWA. 12 embodied carbon means all the CO 2 e emitted in producing materials. 13 Paris [Climate] Agreement 2030 carbon pricing model [$50-100-metric ton CO 2 e]; U.S. H. R. 763 – Energy Innovation and Carbon Dividend Act of 2019; prevailing market rates. 14 U.S. Environmental Protection Agency (EPA): carbon dioxide equivalent or CO 2 e means the number of metric tons of emissions relative the global warming potential (GWP) of one metric ton of CO 2 . $600 billion being the minimum present value of necessary offsets to get to zero net emissions.
