This paper combines detailed travel-survey, transit-service, and land-use data to estimate a model for predicting the role of income and location efficiency in reducing household vehicle-miles traveled (VMT). The research then applies this model to census data collected in the most transit-rich areas of California. The research finds strong justification for California’s current support of location-efficient affordable housing as a strategy to reduce VMT and mitigate climate change.
This working paper was first posted in July 2015. The California Strategic Growth Council commissioned an academic review of the paper in order to consider its use in funding formulas for the allocation of cap and trade funds for the Affordable Housing and Sustainable Communities Program. The working paper was revised in response to review comments and reposted on December 16, 2015.
Northern Ohio has enough wind, solar and biogas potential to meet all of its electricity needs, but only a small fraction of the region's energy comes from these sources. In spite of its vast untapped renewable resources, production of renewable energy in the 9th Congressional District is not economically viable without supportive state and federal policies and incentives. This paper lays the conceptual and analytical foundation for a new energy economy in Northern Ohio.
This study shows that Portland is well-positioned to pilot a tree asset management program that would lay the groundwork for turning its tree canopy into a bondable asset, similar to bridges and roads. The study identified six steps through which Portland and other cities can create a tree asset management program. The study also provides several case studies of other cities that are attempting to turn their trees into assets.
A greenhouse gas emissions inventory was conducted for Chicago and its metropolitanregion for the years 2000 and 2005. Emissions ofcarbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride totaled 34.7 millionmetric tons of carbon dioxide equivalents (MMTCO2e) in Chicago in 2000 with 91 percent of emissions attributable to the indirect emissions associated with electricity consumption, the direct emissions of natural gas use, and the direct emissions of the transportation sector. A portfolio of 33 potential emissions reduction strategies was analyzed that, implemented together, could meet Chicago’s target of reducing greenhouse gas emissions to 25 percent below 1990 levels by 2020. The largest potential for reduction is found in the areas with the largest emissions—energy use in buildings and transport. Compared to its metropolitan region, Chicago is found to have existing transportation efficiencies on a per household basis that can be an example for other communities.
The Regional Green Building Case Study Project analyzes the post-occupancy performance and costs and benefits of 25 LEED projects in Illinois related to: measured energy and greenhouse gas emissions, water, commute transportation, construction and operating costs, green premium, health and productivity impacts, and occupant comfort.
This policy paper makes the case for mandating the inclusion of expense reduction and sustainable living education into a range of federal initiatives, and concludes with recommendations to enhance pending green initiatives by linking them to financial education programming focused on building assets by reducing household expenses in an environmentally responsible manner.
This research was part of a broader effort by the City of Chicago to determine the local ramifications of climate change, for its citizens and for City operations. In addition to CNT’s work on emissions and mitigation strategies, the City engaged researchers to examine climate-change adaptation, economic impacts, and the effects of climate change on City departments.
