Calculation Tools - Progress Report
- GHG Protocol Tools - 2nd Edition: WRI is nearing the completion of its revisions to the GHG calculation tools. These revisions have been guided by the latest IPCC technical guidance, published in 2006.
The following revised tools will be released at the end of February and will be accessible online:
Service-sector tools
Fuel use in facilities: revised emission factors
Electricity purchase: revised emission factors
Cross-sector tools
Stationary combustion: revised emission factors
Electricity, heat or steam purchase: revised emission factors
Sector-specific tools
Adipic acid: updated emission factors
Aluminum: revised method for calculating the CO2 emissions from lime production
Ammonia: an entirely new method for calculating CO2 emissions based on properties of the fuels consumed in manufacture.
HCFC-22: a new method for calculating the HFC-23 emissions based on the carbon and flourine balance efficiencies of the production process
Lime: two new methods that calculate the CO2 emissions based on the properties of either the lime types produced or of the carbonates used in lime manufacture.
Nitric acid: revised emission factors
Pulp and paper: revised emission factors for mobile and stationary combustion, and chemical synthesis
Wood products: revised emission factors for mobile and stationary combustion
- Iron and Steel tool: Both the Excel spreadsheet and PDF guidance document have been written. The final technical review of these documents, led by industry experts, will start in mid-February.
- Natural Gas Transmission and Distribution: The draft guidance document is currently undergoing external review by a consortium of industry associations, multinational companies, and other stakeholders. The final protocol will be finalized by April.
- Financial Sector Carbon Accounting: A draft of the guidance for financial institutions on carbon accounting has passed through internal review and will be going to the banking sector stakeholder group in February. After their comments are integrated where appropriate, this document will go to a broader external review process and be published. Because this document is no longer a tool as was originally envisaged, the review process of this document will differ from how the GHG Protocol calculation tools have been reviewed previously.
- Corporate Balance Sheet Framework and Guidance Protocol: Between October and December, WRI began to develop a discussion paper outlining a corporate balance sheet framework for greenhouse gas assets and liabilities. WRI developed an outline of the discussion paper that identifies the key questions, both technical and policy-related, that must be addressed by an accounting framework for credibly tracking GHG emissions and GHG reduction instruments, such as offsets and allowances, to help companies credibly determine their net GHG impact. WRI will finalize the discussion paper by March 2008.
