Most GHG inventories don't fail on math. They fail on decisions made before anyone calculates: where the boundary sits, which Scope 3 categories matter, and whether the method can hold up when a bank, a customer, or an auditor asks how you got the number.

That's why we created our GHG Accounting Guide, built on the GHG Protocol standards. It walks you through the five accounting principles, how to set your organisational boundary, the difference between Scope 1, 2, and 3, all fifteen Scope 3 categories explained in plain language, and a step-by-step checklist for building an inventory that stands up to scrutiny.

Whether you're building your first inventory in a spreadsheet or moving from spend-based estimates toward supplier-specific data, the guide meets you at your stage and shows what it takes to move one step further.
