The Green Deal covers multiple rules and buyer requests; there is no universal supplier form. Before completing a questionnaire, identify which organisation requests data, for which activity and reporting period.
Clarify request scope in writing. For each question, ask for unit, activity boundary, time period, product/site scope and evidence required. Distinguish a regulatory obligation from a buyer's procurement or sustainability questionnaire.
Link data to source records
Match packaging material and weight to product documents or weighing; shipment data to route, vehicle and load records; and energy to the relevant meter or invoice period. State the calculation method and assumptions.
Version the response file
Keep owner, source, period and calculation revision together. Reuse a dataset only when the buyer's scope matches; for an unclear request, ask for its basis and explain any gap.
