Emissions accounting

Define the Scope 1 emissions boundary

Identify the organisation, controlled sources, reporting period and calculation method before reporting direct emissions.

Start with the evidenceOpen assessment tools
01

Set the organisational boundary

Record the reporting entity, consolidation approach, sites and controlled sources. Keep this decision with the inventory.

02

Identify direct emission sources

List stationary combustion, mobile combustion, process emissions and fugitive releases that fall within the selected boundary.

Inzonex removable modular insulation on industrial equipment
Equipment heat loss

Measure exposed hot surfaces

Use measured surface area, temperature and operating hours to calculate heat loss from boilers, kilns, heat exchangers, valves and pipework. Inzonex supplies removable modular insulation for equipment that requires maintenance access.

  • Design target: surface temperature at or below 45 °C, subject to the application and design review
  • Claimed heat-loss reduction: up to 96%, subject to the measured boundary and insulation specification
  • Removable construction for inspection and maintenance access
  • Calculation record available for the selected equipment and operating conditions

Do not add a calculated reduction to an emissions report until the reporting boundary, factor, implementation date and verification method have been approved.

03

Retain activity data and factors

Keep meter records, fuel and material quantities, laboratory data, factors, units, conversions, uncertainty and approvals for the reporting period.

04

Review changes and exclusions

Record acquisitions, closures, methodology changes, missing data and exclusions. Use the applicable reporting programme where a regulatory return is required.

S

Technical sources

No site total or reduction is calculated without the reporting boundary and source data.
