Methodology
• GHG Inventory Software and Limitations
• Source Categories
• Data sources
• Baseline Year
• Analysis & Findings
• Projections
• Existing Measures
2
Inventory Basics
• Report on a fiscal year basis
• Base year should be reliable, reflective, and
complete. Consider:
–
–
–
–
•
National and regional consistency
“Fiscal Year”
Completeness
Always take complete notes!!!
Identify things within your own operational controlWholly owning an operation, facility or source, or
having the ability to make changes in the facilities you
lease.

Overview of scopes and
emission sources

Organizing the Emissions
Inventory Process
• Government Leadership – Broward County
Workgroup
• Lead data coordinator for each Sector
• Let the departments know data request is coming
• Collaborative process for data collection
• Make clear and specific data requests
• Use data collection forms – BC uses a form made
in .pdf designer
• Take detailed notes
5
Broward County Government
Emissions Inventory Accounts for:
• GHG emissions in baseline year 1997
• GHG reductions achieved by the County from
1997 to 2007
• GHG emissions forecast (BAU) through target
year 2015
6
Gov. GHG Emissions Inventory
Source Categories
1. Buildings - GHG emissions generated through the use
of electricity and other fuels.
2. Vehicle Fleet –GHG emissions generated from the use
of fuel for the operation of County owned or leased
vehicles.
3. Employee Commute –GHG emissions generated by the
commute of County government employees to and from
their work.
7
Gov. GHG Emissions Inventory
Source Categories
4. Streetlights –emissions generated by the consumption of
energy (usually electricity) by Broward County operated
streetlights.
5. Water/Sewage –emissions generated by the consumption of
energy (usually electricity) in water and sewage treatment plants
and pump stations.
6. Waste –emissions generated by the disposal of waste
generated by Broward County Government Operations.
7. Other – Other Broward County owned or operated sources of
GHG emissions were considered for this source.

Data Needs: Buildings
Data Needed:
Fuel usage by fuel type for each building and/or facility
•
•
•
•
Electricity
Natural gas (therms, thousand cubic feet, etc.)
Fuel Oil (gallons)
Propane
Data Sources:
Utility accounts depicting total fuel use for each
government building and facility
Total fuel costs for each fuel type (optional but useful)
9
Data Needs: Vehicle Fleet
• Data Needed: Fuel consumption by fuel type or annual
mileage, vehicle type, and fuel type
• Data Sources: Fuel usage records (gasoline, ULSD, CNG,
Biodiesel, etc.)
Common Types of Government Vehicle Fleet:
• Passenger Vehicles
• Light, medium, and heavy duty trucks
• Vanpool Van
• Transit vehicles
10
Broward County Transit Hybrid Bus
Fleet Vehicle powered by CNG
Savings in fuel cost =
$82,000/year
Toyota Prius Hybrid Electric Fleet Vehicle
11
Data Needs: Employee Commute
• Data Needed: Fuel consumption by fuel type or annual
mileage, vehicle type, and fuel type
• Data Sources: Analysis of commuter patterns, employee
surveys, etc.
Types of vehicles:
• Passenger Vehicles
• Light, medium, and heavy duty trucks
• Vanpool Van
12
Data Needs: Streetlights
Data Needed:
Fuel usage by fuel type
• Electricity
• Green Electricity
Data Sources:
Utility accounts depicting total fuel use for each county
owned traffic lights, traffic signals and street signs
Total fuel costs for each fuel type (optional but useful)
13
Data Needs: Water/Sewage
Data Needed:
Fuel usage by fuel type for each facility
•
•
•
•
•
Electricity
Natural gas (therms, thousand cubic feet, etc.)
Fuel Oil (gallons)
Propane
Green Electricity
Data Sources:
Utility accounts depicting total fuel use for each facility
Total fuel costs for each fuel type (optional but useful)
14
Data Needs: Waste
• Data Needs: Waste type, waste amount,
haulage/tipping costs, waste disposal
technology.
• Data Sources: waste disposal amount reported
• May need the number of employees to
estimate the amount per employee.
• Waste type can be determined using
composition studies

Projections Indicators
• Buildings: Projected buildings’ square footage for
target year
• Vehicle Fleet: Estimated fleet size by target year
• Employee Commute: Number of employees by
target year
• Streetlights: Net growth of streetlights, traffic
signals, & illuminated street signs
• Water & Sewage: percentage of electricity growth
by target year
• Waste : Number of employees by target year
20
Accounting for Government Measures
• Measures implemented from 1997-2007.
• Data inputs provided by the Workgroup.
• Each quantifiable measure was entered into the CACP
software to get the GHG emission reductions.
• CACP able to determine cost savings associated with
the project and the payback period.
• Non-quantifiable measures were also listed in the
Report with associated environmental benefits.
• Data can be exported to MS Excel for making graphs,
and pie charts to enhance the way that the data is
displayed.

Energy Conservation
Example of Measures
LED Traffic Signals – Cost savings for 3,000
traffic lights= $1.3 million/ year
First LEED Building: Broward County
South Regional Library- Cost
Savings $31,000/year
Building Retrofit Projects
Cost Savings: $1.5 million/year
Broward County Environmental Monitoring
Lab - LEED Certified Building

Broward County Climate Change
Government Operations
2009 Annual Progress Report
• Board accepted the first Report, which
recommended the annual progress report.
• First Broward County Government
Operations GHG Annual Progress Report
was completed on May 26, 2009.
• Describes actions BC government
implemented during calendar year 2008 &
progress towards achieving the reduction
goal.
• The Progress Report was used as a tool to
show the annual reduction. BC met and
exceeded the annual reduction of 10,184
tonnes eCO2 emissions.
• The Progress Report was a 1 page summary
Report which included an Appendix with
detailed quantifiable and non-quantifiable
measures for 2008.
