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 control-

Wholly owning an operation, facility or source, or having the ability to make changes in the facilities you lease.

Organizing the EmissionsInventory 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

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

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.

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: BuildingsData 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

Fleet Vehicle powered by CNG

Toyota Prius Hybrid Electric Fleet Vehicle

Broward County Transit Hybrid Bus

Savings in fuel cost = $82,000/year

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: StreetlightsData 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/SewageData 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

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.

First LEED Building: Broward County South Regional Library- Cost

Savings $31,000/year

LED Traffic Signals – Cost savings for 3,000 traffic lights= $1.3 million/ year

Building Retrofit ProjectsCost Savings: $1.5 million/year

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.
