CORPORATE SUSTAINABILITY GUIDE
What is sustainability? A corporate data and reporting guide
Understand corporate sustainability, ESG, carbon inventories and TSRS reporting, and plan the data, evidence and approval process behind your report.
Sustainability goes beyond carbon
Corporate sustainability considers an organization's effects on the environment and people, alongside how environmental and social changes affect its future. Energy, emissions, water and waste sit alongside workforce, health and safety, ethics and governance. ESG groups these environmental, social and governance topics. Material topics depend on an organization's activities, value chain and stakeholders. A useful reporting process explains these relationships rather than treating every indicator as equally relevant to every organization.
What does a carbon inventory show?
A greenhouse gas inventory calculates emission sources within a defined organizational boundary and reporting period. Scope 1 covers direct sources, Scope 2 purchased electricity, heat, steam and cooling, and Scope 3 other indirect sources across the value chain. Comparable results require quantities, units, periods, boundaries, emission factors and methods to be retained together. Estimates, missing information and a measured zero have different meanings. The quality of a result depends on the evidence and calculation process behind the total.
An inventory and a TSRS report serve different purposes
TSRS 1 addresses general sustainability-related financial disclosures, while TSRS 2 addresses climate-related disclosures. A report goes beyond an emissions table to connect governance, strategy, risk management, metrics and targets. Organizations assess how material risks and opportunities relate to their operations and financial prospects. Applicability and current obligations must be assessed against official sources and the organization's circumstances. Software supports preparation and control; organization-specific judgement and final responsibility remain with the reporting organization.
Build a dependable path from data to report
Start with organizational boundaries, sites, periods and responsibilities. Establish shared definitions and collect activity data with invoices, meter records or other supporting evidence. Retain the calculation method and factor source. Separate preparation from review and explain disclosure gaps and changes between periods. Link approved data to report narratives, charts and tables, and preserve the version used for publication and assurance preparation. Generating narrative alone does not establish a reliable evidence chain.
