Smarter Infrastructure: Location & ProtectionConstruction of new transportation infrastructure in an area threatened by sea-level riseis probably the least desirable strategy. Notwithstanding the expense of repairing stormdamagedroadways following an initial event, there is reason to believe that future eventswould occur with ever-increasing probability. In effect, we would be “shoveling againstthe tide.”A recommended action is to perform an analysis of the transportation infrastructurelocated in threatened areas. This information will help identify needed upgrades (e.g.,raising roadbeds, retaining walls, etc.) and guide new infrastructure away fromthreatened areas.2.1.7 DOCUMENTING GREENHOUSE GAS EMISSIONS REDUCTION FORGREENDOT IMPLEMENTATIONMassDOT, using its statewide travel demand model, has provided the <strong>Cape</strong> <strong>Cod</strong> MPOwith statewide estimates of CO2 emissions resulting from the collective list of allrecommended projects in all the Massachusetts RTPs combined. Emissions areestimated in the same way as the criteria pollutants (volatile organic compounds,nitrogen oxides, and carbon monoxide) whose emissions are required for the air qualityconformity determination (for further description, see Appendix-Air QualityConformity. However, the CO2 emissions shown here are part of an effort separate fromthe conformity analysis and are not part of those federal standards and reportingrequirements.The Global Warming Solutions Act (GWSA) legislation requires reductions by 2020 andfurther reductions by 2050, relative to the 1990 baseline. The project mix from this RTP(and all other RTPs) was modeled for both 2020 and 2035 using an Action (Build) vs.Baseline (No-Build) analysis to determine the CO2 emissions attributed to the all MPO’smix of projects and smart-growth land use assumptions. The estimates of the modeledCO2 emissions are provided below:TABLE 1: MASSACHUSETTS STATEWIDE CO2 EMISSIONS ESTIMATESYearCO2Action EmissionsCO2Base EmissionsDifference(Action – Base)2010 101,514.4 101,514.4 n/a2020 105,747.5 105,856.4 -108.92035 115,034.1 115,028.0 6.1(All emissions in tons per summer day)<strong>Cape</strong> <strong>Cod</strong> <strong>Regional</strong> <strong>Transportation</strong> <strong>Plan</strong> | August 2011Chapter 2.1: Land Use/EnvironmentPage 65
