Clean Cities Coalitions 2020 Activity Report
12/29/2021
Clean Cities coalition activities resulted in an EUI of nearly 1 billion GGE, comprised of net alternative fuels used and energy savings from efficiency projects, in 2020. Clean Cities coalition and stakeholder participation in vehicle and infrastructure development projects remained strong, although transportation activity and resulting EUI decreased in 2020 due to the COVID 19 pandemic. Coalition-reported activities prevented nearly 5 million carbon dioxide-equivalent tons of emissions (only GHG emissions are reported here; criteria pollutants and other emissions are not included in this report). The GHG benefits increased in 2020 despite a decrease in EUI because coalitions focused more on technologies with higher GHG benefits per GGE reduced and because the lifecycle of many alternative fuels such as electricity or biofuels is becoming less carbon intense. Coalitions were successful in securing project grant awards from numerous outside (non-DOE) sources. The 90 project grant awards in 2020 generated $151 million in funds from coalition members and project partners in addition to $12.8 million in DOE grant funds. Coalitions also collected $1.1 million in stakeholder dues and $3.1 million in operational funds from host organizations. In macro terms, this non-DOE supplemental funding represents a 4:1 leveraging of the $38 million that was included in the VTO Technology Integration budget in 2020. Clean Cities coordinators spent nearly 135,700 hours pursuing their coalitions’ goals in 2020. The average coordinator is quite experienced and has held the coordinator position for nearly eight years. Coordinators logged more than 3,290 outreach, education, and training activities in 2020, which reached an estimated 31 million people. Activities that reached underserved communities were tracked for the first time in 2020 and accounted for 17% of all activities.

Clean Cities coalition activities resulted in an energy use impact (EUI) of over 1 billion gasoline-gallons equivalent (GGE), comprised of net alternative fuels used and energy savings from efficiency projects, in 2019. Participation in vehicle and infrastructure development projects remained strong, as did alternative fuel use and resulting overall EUI. Clean Cities coalition activities reduce emissions as they impact energy use. Coalition-reported activities prevented nearly 5 million carbon dioxide-equivalent tons of emissions (only greenhouse gas [GHG] emissions are reported here; criteria pollutants and other emissions are not included in this report). Coalitions were successful in securing project grant awards from numerous (non-DOE) outside sources. For other Federal, State, and local agencies and private sector foundations, see funding section on page 24. The 82 project grant awards in 2019 generated $225 million in funds from coalition members and project partners along with $9.5 million in DOE grant funds. Coalitions also collected $1.2 million in stakeholder dues and $1.6 million in operational funds from host organizations. In macro terms, this supplemental funding represents nearly a 6:1 leveraging of the $38 million that was included in the VTO Technology Integration budget in Fiscal Year 2019. Clean Cities coordinators spent nearly 136,000 hours pursuing their coalitions' goals in 2019. The average coordinator is quite experienced and has held his or her position for at least eight years. Coordinators logged more than 3,525 outreach, education, and training activities in 2019, which reached an estimated 23 million people.

Co-Optimization of Fuels & Engines. Toxicology and Biodegradability of Tier Three Gasoline Blendstocks: Literature Review of Available Data
9/24/2019
This study provides framework for decision makers to more fully evaluate the toxicology and biodegradability of the tier three gasoline blendstocks developed under Co-Optima. These Co-Optima blendstocks were compared to gasoline surrogate compounds, providing guidance for future consideration as the project progresses. Due to the complexity of the subject area, all compounds were considered only in their pure form, not as complex mixtures with gasoline, which was outside the scope of this study. The metrics applied to the blendstocks were environmental transport and fate, environmental and human health toxicity, and environmental regulatory framework. The blendstocks (cyclopentanone; diisobutylene; 2-methylfuran; 2,5-dimethylfuran; isobutanol; ethanol; and isopropanol) presented limited human toxicity based on the information available. All the blendstocks migrated primarily into air or water, with little mobility between these compartments. Coupled with aerobic and/or anaerobic biodegradability, long term environmental persistence is unlikely, with the only exception being diisobutylene, which was not biodegradable. Additional work should focus on the environmental impact of these blendstocks in complex mixtures, such as gasoline, which will represent more real world scenarios.

Clean Cities Coalitions 2017 Activity Report
5/14/2019
The U.S. Department of Energy's (DOE's) national network of Clean Cities Coalitions advance the nation's economic, environmental, and energy security by supporting local actions to promote the use of domestic fuels within transportation. The nearly 100 Clean Cities coalitions, whose territory covers 80% of the U.S. population, bring together stakeholders in the public and private sectors to use alternative and renewable fuels, idle-reduction (IR) measures, fuel economy improvements, and new transportation technologies as they emerge. To ensure success, coalitions leverage a robust set of expert resources and tools provided by national laboratories and DOE. Each year, Clean Cities coordinators submit annual reports of their activities and accomplishments for the previous calendar year. Data and information are submitted via an online tool that is maintained as part of the Alternative Fuels Data Center (AFDC) at the National Renewable Energy Laboratory (NREL). Coordinators submit a range of data that characterize the membership, funding, projects, and activities of their coalitions. They also submit data about sales of alternative fuels; use of alternative fuel vehicles (AFVs), plug-in electric vehicles (PEVs), and hybrid electric vehicles (HEVs); IR initiatives; fuel economy improvement activities; and programs to reduce vehicle miles traveled (VMT). NREL analyzes the submitted data to determine how broadly energy use in the U.S. has shifted due to coalition activities, which are summarized in this report.
