Carbon Footprint

The total amount of greenhouse gases that are emitted into the atmosphere each year by an

• rganization or company, either directly or

indirectly.

Greenhouse Gases

• Carbon dioxide (CO2)
• Methane (CH4)
• Nitrous oxide (N2O)
• Hydrofluorocarbons (HFCs)
• Perfluorocarbons (PFCs)
• Sulfur hexafluoride (SF6)
• Nitrogen trifluoride (NF3)

Steps to the Reporting Process

Identify your reporting boundaries Identify your facilities and sources Identify your facilities and sources Organize and collect data on emission sources Organize and collect data on emission sources Quantify and report emissions Quantify and report emissions

Determine which operations, facilities, and sources should be included

Things to consider:

• Geographic region?
• All or some of your facilities?
• Which greenhouse gases?

Identify your reporting boundaries

Identify your reporting boundaries Identify your reporting boundaries Identify your facilities and sources Organize and collect data on emission sources Organize and collect data on emission sources Quantify and report emissions Quantify and report emissions

Steps

What is a “facility”? Typically a single physical premise

• E.g. office building, water treatment

plant, pump station OR, can be aggregation of smaller or distributed emissions sources

• E.g. vehicle fleet, water distribution

system

Identify your facilities and sources

What is a “source”? Physical object or activity that emits greenhouse gas emissions

• Vehicle combusting gasoline
• Water boiler combusting natural gas
• Electricity consumed in buildings
• Cooling systems leaking refrigerants

Identify your facilities and sources

An entity will usually have multiple facilities. A facility can have multiple sources associated with it. Southern California Water Agency (Entity)

Headquarters Building– LA County (Facility)

• Electricity for lighting, computers, etc. purchased

from SCE

• Boilers – natural gas purchased from SoCal Gas
• Refrigerators – refrigerant leakage
• Forklifts – propane

Identify your facilities and sources

Steps

Identify your reporting boundaries Identify your reporting boundaries Identify your facilities and sources Identify your facilities and sources Organize and collect data on emission sources Organize and collect data on emission sources Quantify and report emissions Quantify and report emissions

Where to find data?

Electricity or Natural Gas

• Utility bills
• Accounting department
• Utility account managers

Fuel (generators, pump equipment, etc.)

• Bulk fuel purchase records

Vehicles

• Fuel usage logs and mileage records
• For large organizations, may be tracked in fleet

management system (e.g. Voyager)

Organize and collect data on emission sources

Data Management

• Where does my data live?
• Do I have a good paper trail?
• Would someone new be able to

understand the process?

Organize and collect data on emission sources

Scope 1, 2, and 3

Organize and collect data on emission sources

Graphic via Greenhouse Gas Protocol - https://ghgprotocol.org/

Scope 1 - Direct

• Boilers
• Generators
• Vehicles
• Refrigerators

Scope 2 - Indirect

• Purchased electricity
• Purchased heating
• Purchased steam

& cooling

Scope 3 –Indirect (Optional)

• Employee commuting
• Business travel
• Upstream and Downstream

activities such as waste disposal

Biogenic CO2

• Biogas from wastewater treatment
• Biodiesel
• Captured methane from landfills

Identify your reporting boundaries Identify your reporting boundaries Identify your facilities and sources Identify your facilities and sources Organize and collect data on emission sources Organize and collect data on emission sources Quantify and report emissions Quantify and report emissions

Steps

Activity Data: quantity of fuel or material that, when used, emits GHGs Emission Factor : converts activity data into amount

• f GHGs

GHGs

X =

Quantify and report emissions

e.g. gallons of gasoline, SCF of natural gas, Mwh of electricity e.g. 9.13 kg CO2 emitted per one gallon

• f motor gasoline

combusted

Once you have the data, how do you calculate emissions?

Activity Data: quantity of fuel or material that, when used, emits GHGs Emission Factor : converts activity data into amount of GHGs

GHGs

X

=

100 gallons

• f gasoline X

9.13 kg CO2 / gallon = 913 kg

• f CO2

Quantify and report emissions

Quantify and report emissions

Scope 2 Accounting (Purchased Electricity, Steam, Heat or Cooling) Two accounting methods help clarify renewable energy claims and accounting:

• Location-based method
• Market-based method

Location-Based Method

• Reflects emissions

as they occur on the local grid

• Primarily uses grid-

average emission factors

• I.e. emission factors

reflecting emissions profile of power consumed in region

• Reflects overall

fuel/generation mix

• f power in region

Quantify and report emissions

Market-based Method

• Reflects the GHG emissions

associated with choices you make about energy supply or purchase.

• Allows you to claim the specific

emission rate associated with energy purchases

• Emission factors specific to

renewable energy purchases: RECs, PPAs, etc.

• Utility-specific emission factors

Quantify and report emissions

Market-based Method

Quantify and report emissions

If your organization purchases green power with a specified emissions rate, your organization can generally claim this in the market-based method

• E.G. utility green power program,

community choice aggregator power product

Tracking over Time

Setting a Base Year

• Setting and adjusting a base year

provides a standardized benchmark that reflects an

• rganization’s evolving structure
• Allows changes in
• rganizational structure to be

tracked in a meaningful fashion

• Communicates reduction efforts

Verification

• A third-party audit of your GHG inventory to

confirm that it meets relevant accounting standard (e.g. General Reporting Protocol) and is free of misstatements

• Ensures quality and integrity of reported data,

drives improvements in organizational reporting practices

• Widely practiced in mandatory and voluntary

GHG programs worldwide
