Measuring GHG Emissions Energizing Cleaner Production Management Course
Session Agenda: GHG types and sources GHG Indicator to calculate emissions GHG accounting and reporting
But first… In what step(s) of the methodology is (energy and) GHG measurement relevant?
GHG types and sources:GHG sources • Industrial sources • Fuel use • Electricity use • Industrial processes • Transport • Non-industry and natural sources • Volcanoes • Cattle • Forest fires • Others
GHG Indicator • Based on UNEP/IPCC methodology for GHG emission calculations • Provides common method for reporting GHG emissions • Used by organizations to calculate GHG emissions from energy use and other sources • Used by Governments to translate national GHG targets (e.g. Kyoto Protocol) to industrial targets
GHG Indicator:Methodology Raw data Conversion Aggregation Normalisation 1. Fuel use 2. Electricity use Total GHG emissions Normalised GHG emissions GHG emission factor 3. Industrial processes 4. Transport
GHG Indicator:2. Electricity Use Exported electricity is not included in the total
GHG Indicator:3. Industrial Processes CO2 is released when lime is burned
2.9% 43.8% GHG Indicator:Reporting
GHG Indicator Quiz Let’s test what you have learnt!
GHG Accounting and Reporting Reasons for GHG accounting and reporting • Internal reporting to measure progress against targets & identify EE opportunities • Legal requirement to report • Voluntary reporting under programs • Public environmental / CSR reports • Emissions trading schemes • CDM or JI • Other…
GHG Accounting and Reporting The GHG Protocol lists 5 accounting & reporting principles: • Relevance • Completeness • Consistency • Transparency • Accuracy
GHG Accounting and Reporting:Relevance Define boundaries: • Organizational structures • Operational boundaries • Business context • Specific inclusions / exclusions A multinational operates a plant but owns only 60% of shares Do you count 100% or 60% of emissions?
GHG Accounting and Reporting:Completeness Include all GHG sources & activities • Fuel use • Electricity use • Industrial processes • Transport Sometimes companies do not include all emission sources / activities Can you think of reasons why?
GHG Accounting and Reporting:Completeness (cont.) • # Direct and Indirect Emissions of a Company Source: GHG Protocol, www.ghgprotocol.org, adapted from NZBSCD
GHG Accounting and Reporting:Consistency Meaningful comparison of emissions over time • Production changes • Process changes • Acquisitions, mergers, sales • Outsourcing Why is it important that GHG emissions be compared between different years?
GHG Accounting and Reporting:Transparency It is clear how emissions were calculated (“audit trail”) • Measurements • Assumptions • Calculation methods • References • Exclusions or inclusions Who makes use of the “audit trail” of data?
GHG Accounting and Reporting:Transparency (cont.) • Independent External Auditors • Review of inventory • Provide assurance on data quality & accuracy • Corporate Team • Check quality of incoming data • Compile data • Analyze emission inventory and forecast against BP’s GHG target • 320 Reporting Units: • Complete standard pro-forma spreadsheet every quarter: emissions & forecasts • Account for variances • Use BP’s GHG Reporting Guidelines
GHG Accounting and Reporting:Accuracy Data must be “materially” accurate • Measurement methods • Calculation methods • Aggregation and reporting What can a company do to improve data accuracy?
GHG Accounting and Reporting:Reporting Emissions Minimum information to be reported • Company and inventory boundary • Organizational boundaries • Operational boundaries • Reporting period
GHG Accounting and Reporting:Reporting Emissions (cont.) Minimum information to be reported • Information on emissions • Direct (scope 1) and indirect (scope 2) emissions – total and separate • Emissions for 6 GHGs • Current and base year emissions • Significant changes since base year • Direct CO2 emissions from biologically sequestered carbon • Methodologies for calculation/ measurement • Specific exclusions
GHG Accounting and Reporting:Verification of GHG Emissions • Verification is objective assessment of • Accuracy and completeness of GHG information • Conformity to GHG accounting and reporting principles • Why verification? • Increased credibility of reported emissions • Increased senior management confidence • Improved accounting & reporting • Preparation for mandatory verification requirements
Summary • GHG emission accounting and reporting increasingly important • GHG Indicator useful tool to calculate GHG emissions • Don’t assume data company gives you are accurate and complete!! (think of the 5 principles) • Verification improves the credibility / reliability of GHG data
