P a g e | 65 Offsets may include products that target other transportation-related environmental impacts including reducing mobile-sourced emissions (exhaust and non-exhaust) and mitigating Urban Heat Islands . Transportation system related carbon including both imbedded and systematic emissions approximate one-third of all emissions (Table 7) . As the paving industry necessarily faces carbon reduction mandates, extended boundary exposure creates both potential regulatory and financial risk as well as opportunity to differentiate. Table 7 – Emissions by Sector Source: NAPA Three critical questions are rapidly arising for the paving industry: 1) How will the asphalt and concrete paving industries reach 50% carbon reductions by 2030 and 100% by 2050 when reduction opportunities in mix design and construction are so limiting? 2) What roadway microenvironment (systematic) impacts beyond materials, construction, and maintenance exist? Will the paving industry harness and take control of our future? 3) Or will use phase or scope 3 emissions become a liability for the paving industry because no force majeure will be permitted (Figure 39) ?
