A useful textile greenhouse-gas inventory begins with a defined reporting boundary, traceable activity data and documented emission factors. It should not start from a generic claim about which scope is “usually” largest. The result depends on the company’s sites, energy system, products, geography, reporting period and value chain.
Corporate Inventory or Product Footprint?
A corporate GHG inventory accounts for emissions associated with an organization during a reporting period. A product footprint or life-cycle assessment answers a different question about a defined product and life-cycle boundary. State which result is being prepared before collecting data; do not mix the two in one total.
Step 1: Define the Inventory
Document the reporting organization, consolidation approach, sites, reporting period, gases, base year, exclusions and intended assurance level. Record any leased assets, captive power, common utilities, subcontract processing and data gaps.
- Which legal entities, facilities and operations are included?
- Which operational-control or equity-share approach is being used?
- What reporting period and base year apply?
- Which exclusions or estimation methods need disclosure?
Step 2: Map Sources by Scope
Scope 1: Direct Emissions
Scope 1 covers direct emissions from sources owned or controlled by the reporting company. Depending on the site, these can include fuel combustion and relevant process or fugitive sources. Map boilers, thermic-fluid heaters, generators, owned vehicles, refrigerants and other controlled sources to the defined boundary.
Scope 2: Purchased Energy
Scope 2 covers indirect emissions from purchased or acquired electricity, steam, heat and cooling consumed by the company. Apply the GHG Protocol’s location-based and market-based reporting rules where applicable, and retain evidence for contractual instruments and supplier claims.
Scope 3: Other Value-Chain Emissions
The GHG Protocol Scope 3 Standard organizes other value-chain emissions into 15 categories. Screen all categories, identify those relevant to the company and document exclusions and estimation methods. Avoid declaring one category dominant until the company’s own screening supports that conclusion.
Step 3: Collect Auditable Activity Data
Use invoices, meters, fuel purchase and stock records, production logs, refrigerant records, transport data, supplier data and other traceable evidence. Assign an owner, unit, time period, source document and quality rating to each dataset. Reconcile totals to accounts or operational records where possible.
For mixed manufacturing sites, define how common energy and utilities are allocated to processes or product families. Disclose estimates and avoid false precision when meter or supplier data are incomplete.
Step 4: Calculate and Retain Factor Evidence
GHG emissions = activity data × applicable emission factor
Apply any required gas and global-warming-potential conversion after the basic calculation. Select factors appropriate to the geography, year, fuel or material, technology and reporting framework. Retain the factor publisher, version, year, unit, link and every conversion. Do not present a factor without its source and applicability.
Step 5: Quality Control and Reporting
Check units, duplicate sources, missing months, meter boundaries, opening and closing stock, renewable-energy claims, Scope 2 instruments, supplier estimates and category overlap. Report absolute emissions and intensity metrics with defined denominators, methodology changes, exclusions, uncertainty and base-year recalculations.
Independent assurance may be appropriate when customers, finance providers or public reporting rely on the result. Keep the calculation workbook, source evidence, approvals and change log together so the inventory can be reproduced.
Turn the Inventory into Decisions
Use the verified inventory to rank projects by measured emissions, technical feasibility, cost and data confidence. Continue with the guide to reducing textile carbon emissions with measured results.
Do not merge water compliance with carbon accounting. A textile ZLD project needs a separate legal, water-quality and mass-balance decision even when its energy use also affects the GHG inventory.
