The Climate Registry
A non-profit organization governed by states, provinces and native sovereign nations in North America
The only North American voluntary greenhouse gas (GHG) emissions registry for corporate inventories
A community of 400 business, government and NGO leaders
Partnered with IOU’s to form The Cool Planet Project to provide complimentary assistance with GHG accounting to qualifying customers

Reducing Energy Reduces GHG’s
1,300 kWh = 1 Ton of Carbon
200 therms = 1 Ton Carbon
One ton of Carbon is emitted when you:Run an average US household for 60 days
Drive 1,900 miles in a mid-sized car
The Cool Planet Project rewards organizations who install large energy efficiency projects with assistance building their GHG inventory
Facilitated by: SDG&E, The Gas Co., SCE

Voluntary Action vs. RegulationRegulatory
State, Regional, and Federal
AB 32, Regional Greenhouse Gas Initiative, EPA Mandatory Reporting Rule
Focuses on certain sectors and thresholds
Reporting is at facility or source level
5
VoluntaryIndividual, Corporate, Municipal
Internal environmental initiatives, ICLEI, LEED, The Climate Registry, Global Reporting Initiative
Open to all sectors, no threshold
Reporting is at the entity level, “carbon footprint”
Voluntary Action Should Follow Best Practice Standards

What is a GHG Inventory?
Quantitative summary of GHG emissions associated with your operations
Commonly referred to as….
Your “carbon footprint”

6 Kyoto Greenhouse Gases (GHGs)Carbon Dioxide (CO2)Fossil fuel combustion (boilers, turbines, compressors, digesters, backup generators) and deforestation
Hydrofluorocarbons (HFCs)Cooling and refrigeration; industrial and commercial needs; propellants; flame retardant;
Methane (CH4)Landfills; livestock and livestock wastes; rice fields; wastewater treatment; production and distribution of natural gas and petroleum, and coal production
Nitrous Oxide (N2O)Agriculture, (soil cultivation practices; use of commercial & organic fertilizers), and fossil fuel combustion
Perfluorocarbons (PFCs)Aluminum production; medical applications; refrigerants; and semi conductor manufacturing
Sulfur Hexafluoride (SF6) Electrical transmission and distribution systems; circuit breakers; insulators

Principles of a GHG Accounting
Relevance: inventory should reflect the organization’s emissions and
decision-making
Completeness: account for all GHG sources and activities within
Defined inventory boundaries
Consistency: consistent methodologies ensure meaningful
comparison of inventory data over time
Transparency: necessitating full disclosure of all assumptions,
leaving a clear audit trail
Accuracy: provides reasonable assurance of the information’s
integrity

Steps for Building an InventoryStep 1: Determine Your Boundaries
Geographic – state, national, international
Control – operational, financial, equity share
Step 2: Identify Emissions Sources and Collect DataScope 1, 2 or 3
Most data is available in existing systems
Step 3: Calculate EmissionsUse standardized and up to date protocol and methodologies to calculate emission (Climate Registry Information Systems)
Step 4: Communicate FindingsReport information to stakeholders and decision-makers
Report information to public through sustainability reports and/or The Registry
Step 5: Evaluate DataWhat did you learn? Integrate information into decision-making

Reporting Protocols
1. Provide step-by-step guidance on building an inventory (see previous slide steps 1-4)
2. Ensure consistency with international standards
3. Ensure comparability between reporting years
4. Ensure accurate up-to-date methodologies and emissions factors

Reporting Protocols
General Reporting ProtocolThe Climate Registry’s standard guidance
Detailed how to guide
Updated annually
Local Government Operations ProtocolDeveloped by ARB, CCAR, ICLEI, and The Climate Registry
Maintained and updated by The Climate Registry w/input
Provides tailored guidance for quantifying local government emissions
Community ProtocolIn development- spearheaded by ICLEI
Important to ensure consistency across jurisdictions
Important to address methodological challenges 13
