affordable housing (which is documented to generate lower VMT per household).
Complementing these features are trip reduction strategies such as low or no parking, transit passes, bikeshare, and carshare memberships. Regional daily average of household CO2 emissions from travel is 69.4 lbs, according a recent report by the Council of Governments.†† 15 We analyze the CO2 savings from low-VMT projects by using the same travel model analysis which produces the VMT number to generate a CO2 emissions estimate. The project’s CO2 savings is the difference between its estimated emissions and the regional average daily per household
CO2 emissions from driving, and factors in reduction credits from transit service, bicycling, and walkability.
Platinum Certification For projects that significantly exceed their certification benchmarks, GreenPlace offers platinum certification. These exceptional projects include either zero parking or an outstanding combination of affordable housing or TDM measures. GreenPlace’s four types of platinum certifications are: •
Zero Parking
•
100% Affordable
•
Low Parking +TDM
•
High TDM.
The April 2016 COG report explains that mobile transportation comprises about 34% of regional CO2 emissions. Of that figure, about 60% is attributable to passenger vehicles and light trucks. The calculation of 69.4 lbs CO2 equivalent (CO2e) per household daily for mobile source CO2e emissions is derived from the disaggregated figure of 23,097,738 metric tons of CO2e from mobile transportation sources in 2012. ††
