SUSTAINABILITY REPORTING · Workflow idea

Bring emissions data together with the assumptions that shape it.

For an organization with authority to use its operational data, organize energy, fuel, travel, and selected supply-chain figures into a documented emissions estimate and draft report. Boundaries, units, factors, and source data may be incomplete or change over time; preserve methodology and evidence, distinguish measured values from estimates, reconcile calculations, and have a sustainability or assurance professional review results before external disclosure or compliance use.

01 / The starting point

A clear request.
A useful direction.

Approved operational records, documented calculation methods, and current emission factors

“Prepare a traceable estimate without presenting assumptions or incomplete coverage as verified emissions.”
An example request · Make it specific to your team.

02 / The work

5 tasks.
One useful outcome.

Helps a sustainability team organize activity data, calculate emissions estimates, and prepare a report draft.

  1. Confirm reporting boundaries and period

    Document the included sites, activities, time frame, and responsible data owners.

  2. Collect activity figures with sources

    Record units, source dates, coverage, and whether values are measured or estimated.

  3. Apply documented factors and methods

    Use approved factors for the relevant region and period and retain the calculation basis.

  4. Reconcile totals and identify gaps

    Check arithmetic, duplicate records, missing categories, and assumptions with the source data.

  5. Approve before disclosure or compliance use

    Have a qualified sustainability reviewer verify methodology, evidence, and report wording.

03 / The result

Something useful.
Something to build on.

A dated emissions summary with data sources, calculation notes, coverage gaps, and reviewer status.

The handoff

A dated emissions summary with data sources, calculation notes, coverage gaps, and reviewer status.

Keep in mind

Emission factors and organizational boundaries affect totals, while incomplete inputs can hide uncertainty. Keep factors dated and sourced, explain estimates and exclusions, validate arithmetic against the chosen methodology, and obtain qualified review before public or regulatory reporting.

04 / Make it yours

Set the brief.
Set the standard.

A few choices shape the work around your team.

Choose reporting boundaries and standards

Document organizational scope, reporting period, and the applicable calculation framework.

Maintain current factor sources and units

Track factor versions, geography, units, and effective dates.

Protect operational and employee data

Limit access to necessary records and redact personal details from reports.

Require qualified review and audit evidence

Keep source records and approval notes available for assurance or correction.
