In most businesses, sustainability reporting is seen as a report-writing exercise. Yet the report itself is the smallest part of the job; the real burden is collecting the data behind every indicator in it. Energy and fuel consumption, purchased electricity, vehicle fleet consumption, water withdrawal and discharge, waste quantities, headcounts and turnover rates, workplace accident statistics, training hours and supplier information. Each of these sits in a different department, with a different person, in a different format.
In the first year, this data is gathered by hand through an extraordinary effort. Emails go out, Excel files are collected, gaps are filled with estimates, and the report comes out. The second year demands the same effort again — except this time no one remembers how last year's figure was calculated. Comparability is lost, because the method was never on record. And when an audit or assurance engagement arrives, the very first question is exactly that: where did this number come from?
The infrastructure we build is designed to answer that question. Every indicator is tied to a data source, an owner, a calculation method and a period. Data that can be taken automatically is pulled from systems; for items that must be entered by hand, forms and a calendar are set up, and who entered what, and when, is logged. Calculation methods and the factors used are versioned, so the same figure can be reproduced with the same method two years later.
Let us state the limit clearly: sustainability reports may be subject to independent assurance, and we are not the party performing that engagement. You and your consultant decide the report's content, which standard it follows and how the indicators are interpreted. Our job is the data infrastructure: collecting the data at source, protecting its trail and keeping the reporting period from turning into a collection scramble. That separation works in your favour in the assurance process.
