Most sustainability strategies don’t fail loudly. They fade. The launch goes well, the document is well designed, the board signs it off. Eighteen months later, someone asks what has actually changed, and the honest answer is: not much.

This isn’t usually a failure of ambition or intelligence. The strategy is often sound. What’s missing is the connective tissue between the strategy and the organisation that has to deliver it. In our experience, strategies stall for a small number of recurring reasons.

Strategy development gets senior attention, external support and protected budget. Implementation gets whatever is left. The imbalance shows up everywhere: organisations will fund a strategy refresh every three years but hesitate to fund the two roles needed to deliver the current one.

Ask an organisation about its sustainability strategy and you’ll usually get a confident answer. Ask who has the authority to change a product specification, a procurement standard or a capital allocation decision because of that strategy, and the answer gets vaguer. That vagueness has a name: the operating model gap.
