2007-2012.2013
2017*2019
This memo is to request City Council approval of the Fleet Electrification — Rationale and
Implementation Guidance which sets the value for the social cost of carbon to $30 per metric
tons of carbon dioxide equivalent (MtCO2e) in accordance with the 50% by 2030 Community
Climate Action & Resiliency Plan.
BACKGROUND
The 50% by 2030 Community Climate Action & Resiliency Plan (50% by 2030 Plan), adopted in
2013 and updated in 2020, is a non -binding, voluntary effort to identify opportunities to reduce
Dubuque's community greenhouse gas emissions and serves as an integral step in moving
towards our Sustainable Dubuque vision. The 50% by 2030 Plan calls for an update to the City
vehicle purchasing policy (including The Jule transit) and budget process to default to electric
vehicles (EVs) and alternative fuels, with traditional internal combustion engine (ICE) vehicles
as optional, requiring proof of need. The goal as outlined in the 50% by 2030 Plan is to achieve
50% EVs within City Fleet by 2030 and maximize utilization of other clean technologies for fleet.
City staff worked closely with a team of consultants, with expertise in facilitating and developing
an update to our fleet electrification feasibility in 2020 and has spent the past two years working
on various projects including two successful VW settlement grants for EV chargers which will be
installed by spring of 2023. We have been assessing various city owned properties for
additional charging capacity and infrastructure as well.
On December 21, 2020, City Council heard a presentation about plans to electrify the city -
owned fleet. The Council voted unanimously to consider a valuation to apply to the vehicle total
cost of ownership. The social cost of carbon metric is proposed to be used in vehicle purchasing
decisions to calculate economic damages associated with a rise in greenhouse gas emissions
from burning fossil fuels and other activities. We have since developed guidance and propose
$30/MtCO2e which, while conservative by global standards, it is a relevant place to begin our
efforts in Dubuque.
DISCUSSION
The updated fleet guidance is the mechanism by which City departments can begin
implementation of climate action in major investments (vehicles) and select high -carbon -
impact decisions. "Social cost of carbon" is a term used to place value on the environmental
impact of greenhouse gas emissions, for our purposes, emissions associated with City vehicle
purchases. The value is then factored into vehicle total cost of ownership calculations to
compare the full cost of conventional and electric vehicles purchases and lifecycle costs.
The intent of the City's internal cost of carbon calculation is to normalize the inclusion of
climate impacts into projects, planning and policy decision -making. This practice establishes a
framework that makes the cost of carbon much more visible in decision -making and creates a
consistent mechanism for City staff to quantify actual or modeled costs associated with fleet
vehicles.
While much debate can be made as to the actual valuation of carbon, for our purposes, a
modest $30/MtCO2e is proposed. The Biden administration raised the social cost of carbon to
about $51 per metric ton. As we continue to address climate risk, environmental justice, and
equity, the social cost of greenhouse gases needs to be considered.
In addition to climate benefits, the expansion of clean transportation choices is also critical to
improving air quality in Dubuque. Exhaust from vehicles creates pollution such as ozone and
particulate matter. The impacts of high pollution levels are numerous, such as increased levels
of cardiovascular and respiratory illness, damage to respiratory systems, and even shortened
life spans.
BUDGETIMPACT
This valuation and guidance will be a case -by -case basis and only applied to vehicle purchases
at this time. With Inflation Reduction Act funding to assist with municipal fleet electrification,
there may be no budget implications outside of normal replacement cycle costs.
REQUESTED ACTION
The requested action is for City Council to review and approve the Fleet Electrification —
Rationale and Implementation Guidance and set the social valuation for the cost of carbon to
$30/MtCO2e to be used in total cost of ownership calculations for City vehicle purchases.
Enclosure
City of Dubuque Fleet Electrification —
Rationale and Implementation Guidance
Overview
Dubuque's 50% by 2030 Community Climate Action and Resiliency Plan (50% by 2030 Plan) calls for an
update to the City vehicle purchasing policy and budget process to increase adoption of Electric Vehicles
(EVs) and other clean vehicles and establish minimum fuel efficiency requirements for continue use
Internal Combustion Engine (ICE) vehicles. In 2018, the transportation sector represented approximately
20% of local community greenhouse gas emissions. As the recently updated 50% by 2030 Plan states,
prioritizing the use and purchase of low- and no -emission vehicles, such as EVs, demonstrates the City's
leadership in transitioning to a cleaner fleet and reducing municipal vehicle emissions, setting an
example for the larger community to join in decreasing greenhouse gas emissions and costs. A clean
fleet has two main objectives — reducing carbon emissions and improving operational efficiency. Part 1
of this document provides a rationale for purchasing clean vehicles, and Part 2 outlines an
implementation strategy.
The City's non -transit fleet is comprised of 233 vehicles and accounts for just over 50% of all emissions
produced by the city's fleet. At this time, the Administrative Policy 3.09 Purchase of City Vehicles has
been updated to focus on fleet electrification and will initially apply to light -duty vehicles only. The
terms will expand to cover medium and heavy-duty fleet vehicles as electric models become
commercially available and cost competitive. Electrification will be coupled with other sustainable fleet
strategies including idle reduction, route optimization (as possible), review of fleet usage and rightsizing
the fleet.
Part 1: Electric Vehicle (EV) and Other Clean Vehicle Purchase Rationale
Rationale for Municipal Fleet Electrification Policy Recommendations
There are numerous potential benefits that support development of a City Fleet & Vehicle Electrification
policy, in conjunction with the existing City Vehicle Purchasing Policy. Some of the primary reasons
include:
Greenhouse gas emission reduction: Dubuque's Community Climate Action, Adaptation and
Resiliency Plan (50% by 2030 Plan) includes a target for the city to reduce total greenhouse gas
emissions by 50% of 2003 levels by 2030, and in 2020, City Council set a target of being the first
city in the State of Iowa achieving carbon neutrality as recommended in the 50% by 2030 Plan.
The 50% by 2030 Plan outlines several municipal and community -wide strategies to achieve the
City's climate protection goals, such as the adoption of electric vehicles. On -road vehicle travel
accounted for 15% of our 2003 baseline emissions and in the most recent update accounted for
17%.
• Air quality, health & equity: Mobile sources contribute substantially to criteria pollutant
emissions in Dubuque, both carbon monoxide (CO) emissions, and nitrogen oxides (NOx)
emissions. These criteria pollutants contribute to respiratory, cardiovascular, and other health
issues. Minority and underserved communities are frequently disproportionately impacted by
air pollution, and in Dubuque suffer from related health impacts - such as asthma - in greater
numbers.
• Strategic electrification: As more solar and wind power is used as a source for regional energy,
the electricity used to power EVs will become cleaner. In its 2020 Clean Energy Blueprint, Alliant
Energy pledged to eliminate all coal from their generation fleet by 2040 and aspiring to achieve
net -zero carbon dioxide emissions from the electricity generated by 2050.
• Cost-effective: Declining upfront costs for EVs means that transitioning to electric fleets is
becoming affordable, particularly for light -duty vehicles. Additionally, incentives, such as offered
by dealers and Alliant Energy, plus awards from the State of Iowa Department of Transportation
Volkswagen Clean Air Act Settlement program, are increasingly available to help offset the
upfront costs of fleet electrification. Recent federal legislation has made the transition to EVs
even more affordable for municipalities.
• Total cost of ownership savings: Due to lower fuel costs and fewer maintenance needs, electric
vehicles are estimated to provide savings on a total cost of ownership basis, particularly when
replacing high mileage, low fuel efficiency vehicles. Fleets across the country have documented
maintenance costs for EVs that are less than half that for conventional vehicles.
• Leading by example: Incorporating EVs into the City fleet helps raise awareness among
employees, auto dealerships and local auto industry stakeholders, and the general public, in
turn enabling greater adoption of EVs.
• Best in class: Dubuque joins other cities that have set goals or created purchasing policies
designed to accelerate vehicle electrification and desires to continue to lead small to midsized
cities.
Clean Vehicle Policy Terms
The changes to the existing City Administrative Policy 3.09 (Purchase of City Vehicles) require
departments to prioritize electric vehicles when procuring new vehicles for the City fleet, except when
there is no electric model to suit the operating needs for the vehicle being replaced, or there is no cost-
effective electric alternative. In those cases, departments are required to prioritize purchase of a clean
vehicle pursuant to the following structure:
(1) plug-in hybrid electric vehicle (PHEV), (2) hybrid -electric vehicle (HEV), (3) alternative fuel or
another vehicle with demonstrated lowered emissions than the vehicle eligible for replacement.
The city will continue to explore charging capabilities and options to support fleet transition.
Definitions:
Cost-effective: An electric vehicle will be considered cost-effective if its estimated lifecycle cost is within
10% of a comparable conventional vehicle's lifecycle cost.
This threshold helps provide a buffer for small variances in the lifecycle cost analysis due to assumptions
that are subject to fluctuation (e.g., future fuel prices). It also accounts for additional indirect social and
2
environmental benefits, such as air pollution reduction and local jobs benefits from EVSE installation,
not captured explicitly in the lifecycle cost analysis. The cost of carbon for vehicle purchases is proposed
to be set to $30/MCO2e (Metric tons of carbon dioxide equivalent) and shall be factored into lifecycle
cost equation.
Lifecycle cost: The lifecycle cost consists of (1) all capital acquisition costs - including vehicle purchase
and any associated charging infrastructure — (2) operating costs over the expected life of the vehicle -
including fuel/energy and maintenance costs- and (3) estimated environmental benefits of avoided
greenhouse gas emissions.
Estimated Clean Vehicle Policy Impact:
Based on projected EV model availability and costs, the analysis projects a policy update as
recommended is expected to result in 9% of total new non -transit purchases being electric vehicles by
2025, and 58% by 2032 (Table 2).

Part 2: Implementation Strategy
Guidance to Departments: City Fleet & Vehicle Electrification
While there are many cost -competitive electric light -duty sedan options in 2022, electric pickup, SUV,
and van models are becoming more readily available, though still difficult to obtain. To respond to this
evolving market, this offers guidance to support departments to make every effort to comply with the
policy and support the City's climate goals, while the policy provisions also offer flexibility for
compliance where needed. The Fleet Supervisor will assist departments to determine the best model
based on operational needs or cost-effectiveness.
We recognize that extreme temperatures as well as hilly terrain can affect the performance of EVs,
contributing to range anxiety. In cold weather, for example, it is recommended to warm up the vehicle
cabin while the EV is still plugged in to avoid using the battery. Extreme heat can also reduce range, and
it is always recommended to keep the batter as cool as possible and park in the shade on hot days. EV
manufacturers are constantly improving battery insulating or ventilation. In heavy duty vehicles,
auxiliary heating/cooling systems running on fuel or using heat pump technologies are also common.
Definitions of Clean Vehicles
• Battery -electric vehicle (BEV) - EVs stand out from most cars on the market in that they don't
have internal combustion engines. Instead of gasoline, these vehicles run solely on battery
power.
• Plug-in hybrid electric vehicle (PHEV) - PHEVs expand on the concept of the standard hybrid
vehicle. They have both an internal combustion engine and a battery -powered electric motor.
This allows the battery to store enough power to feed the electric motor and in turn decrease
your gas usage by as much as 60 percent.
• Hybrid vehicle (HEV) - HEVs run on both an internal combustion engine and an electric motor
that uses energy stored in a battery.

*** Expected savings/cost of future maintenance. (Fleet can assist with life cycle cost numbers and estimates of ICE
and electric past and future.)
Steps for Implementation
1. Identify potential clean vehicle replacement options: Available BEV, PHEV, HEV, and
conventional vehicles can be researched and compared using the following sites (including light -
duty, as well as medium- and heavy-duty vehicles):
• Alternative Fuels Data Center at D.O.E. https://afdc.energy.gov/vehicles/search/
• Fuel Economy Information at D.O.E. www.fueleconomy.gov
2. Evaluate: Do clean vehicle models meet operational needs? As battery technology improves
and costs decline, electric vehicle ranges have been increasing, and are now frequently more
than 200 miles on a single charge. This is likely sufficient for many City vehicles' needs but
should be considered if the vehicle in question is regularly driven longer distances than available
vehicles' ranges. Vehicle ranges can be researched on www.fueleconomy.gov. Other
operational needs to consider may include public safety vehicle capabilities, emergency
response functions, and other operating requirements for specialized vehicles. If long distance
travel is only occasionally necessary, please consider borrowing or use of personal vehicle instead
of using long distance travel as the exception.
3. Review Funding: Are there available incentives or other funds to cover incremental cost?
Departments are encouraged to work with the Sustainable Community Coordinator to pursue
available incentives or to cover the incremental cost of a clean vehicle. Incentives may be
available from dealers, Alliant Energy, the Iowa Department of Natural Resources Volkswagen
Mitigation Settlement Trust program, the Inflation Reduction Act EV Light Duty Tax Credit, and
other sources to help offset the upfront costs of fleet electrification.
4. Evaluate Cost: Are clean vehicle models cost-effective? The remainder of this document offers
guidance for conducting a lifecycle cost analysis as defined by the City Vehicle Purchasing Policy
to determine whether a suitable BEV, PHEV, or HEV replacement vehicle is cost-effective relative
to the baseline conventional model. Departments should procure the lowest -emission cost-
effective clean vehicle, according to the hierarchy of replacement vehicles above. Generally,
vehicles most likely to see cost savings from switching to electric are likely to be driven at least
10,000 miles per year, though this will change as electric vehicle prices continue to decline.
Lifecycle Cost Evaluation Guidance
Departments seeking an exemption on a lifecycle cost basis are encouraged to develop an analysis
utilizing the following equation. The following sources and inputs can be utilized to analyze the lifecycle
cost of an electric vehicle compared with other vehicle types. Lifecycle cost is calculated as follows:
Capital Costs (acquisition and infrastructure, less incentives received)
+ Lifetime Operating Costs (maintenance costs, fuel and/or energy costs, and other annual costs)
+ Lifetime Environmental Costs (cost of carbon associated with vehicle emissions)
Total Lifecycle Cost of the vehicle
5
Individual components under lifetime operating costs and lifetime estimated environmental benefits of
avoided GHG emissions can be calculated using the following equations. Recommended sources and
inputs for these equations are explained further below.
A template is available for departments to utilize using the following inputs and equations.

The table below shows an example of how cost of carbon might factor into the purchase of vehicles at
the city. There are many variables, and we can get exact data. However, this item is time sensitive, so we
used a feasible example (based on current ordered vehicle and EV comparable) using industry -accepted
assumptions and methodology from the US Department of Energy.

This puts the Plug in Hybrid Electric Vehicle option within a 10% total lifecycle cost of the traditional ICE

Vehicle as the most cost effective. If we based decision solely on purchase price the PHEV and the HEV
would not meet the threshold.
