What information must be provided by airports for verification?
In order to facilitate an efficient and effective verification process it is likely that the
airport would need to supply the verifier with the following information to support the
calculation methodology.
airport would need to supply the verifier with the following information to support the
calculation methodology.
- Information about the company's main activities and GHG emissions (types of GHG produced, description of activity that causes GHG emissions)
- Information about the company/groups/organization (list of subsidiaries and their geographic location, ownership structure, financial entities within the organization)
- Details of any changes to the company’s organizational boundaries or processes during the period, including justification for the effects of these changes on emissions data
- Details of joint venture agreements, outsourcing and contractor agreements, production sharing agreements, emissions rights and other legal or contractual documents that determine the organizational and operational boundaries
- Documented procedures for identifying sources of emissions within the organizational and operational boundaries
- Information on other assurance processes to which the systems and data are subjected (e.g. internal audit, external reviews and certifications)
- Data used for calculating GHG emissions. This might, for example, include:
– Energy consumption data (invoices, delivery notes, weigh-bridge tickets, meter readings: electricity, gas pipes, steam, and hot water, etc.)
– Production data (tonnes of material produced, kWh of electricity produced, etc.)
– Raw material consumption data for mass balance calculations (invoices, delivery notes, weighbridge tickets, etc.)
– Emission factors (laboratory analysis etc.). - Description of how GHG emissions data have been calculated:
– Emission factors and other parameters used and their justification
– Assumptions on which estimations are based
– Information on the measurement accuracy of meters and weigh-bridges (e.g., calibration records), and other measurement techniques
– Equity share allocations and their alignment with financial reporting
– Documentation on what, if any, GHG sources or activities are excluded due to, for example, technical or cost reasons. - Information gathering process:
– Description of the procedures and systems used to collect, document and process GHG emissions data at the facility and corporate level
– Description of quality control procedures applied (internal audits, comparison with last year’s data, recalculation by second person, etc.). - Other information:
– List of (and access to) persons responsible for collecting GHG emissions data at each site and at the corporate level (name, title, email, and telephone numbers)
– Information on uncertainties, qualitative and if available, quantitative.
