Methods for Estimating Greenhouse Gas Emissions and Emissions Reductions
(1)
Applicability: If local governments within a metropolitan area are conducting land use and transportation scenario planning to demonstrate that their plans would meet the greenhouse gas emissions reductions targets established in this division, then they shall use the provisions and options in this rule to project future emissions.(2)
Projected Emission Rates: Projections of greenhouse gas emissions must use the emission rates specified in subsection (a) or the flexible option described in subsection (b).(a)
Projections of greenhouse gas emissions may use the emission rates listed below, which are based on the Statewide Transportation Strategy and reflect reductions likely to result by the use of improved vehicle technologies and fuels. Rates are measured in grams of carbon dioxide equivalent per vehicle mile.(A)
In 2040, 140 grams per mile.(B)
In 2041, 134 grams per mile.(C)
In 2042, 128 grams per mile.(D)
In 2043, 123 grams per mile.(E)
In 2044, 117 grams per mile.(F)
In 2045, 112 grams per mile.(G)
In 2046, 108 grams per mile.(H)
In 2047, 103 grams per mile.(I)
In 2048, 99 grams per mile.(J)
In 2049, 94 grams per mile.(K)
In 2050, 90 grams per mile.(b)
Projections of greenhouse gas emissions may use emission rates lower than the rates in subsection (a) if local or regional programs or actions can be demonstrated to result in changes to vehicle fleet, technologies, or fuels above and beyond the assumption in the Statewide Transportation Strategy. One example would be a program to add public charging stations that is estimated to result in use of hybrid or electric vehicles greater than the statewide assumption in the Statewide Transportation Strategy.(3)
Actions in the Statewide Transportation Strategy: Projections of greenhouse gas emissions may assume state actions specified in subsection (a), and may use the flexibility for local actions described in subsection (b).(a)
State Actions: Projections of greenhouse gas emissions may include reductions projected to result from state actions, programs, and associated interactions up to, but not exceeding, the levels identified in the Statewide Transportation Strategy.(b)
Local and Regional Actions: Projections of greenhouse gas emissions may include local or regional actions similar to actions in the Statewide Transportation Strategy if the local governments have authority to and have adopted plans that would implement the actions.
