In short: The 17 UN Sustainable Development Goals, agreed in 2015 with 169 targets to be met by 2030, give businesses a common language for their contribution to society and the environment. Investors use them as a guide for allocating capital, and customers and employees increasingly expect them. TaxDigit's sustainability team maps your value chain to the SDGs, measures impact using recognised frameworks, sets SMART goals and prepares you for the B Impact Assessment, so your claims are evidenced and comparable rather than marketing.
From SDG logos to measured impact
Naming an SDG is only the first step. Real impact measurement asks five questions: what outcome occurs and how important it is to the people affected; who experiences it; how much (scale, depth and duration); what the business contributed compared with what would have happened anyway; and the risk that the impact is different from expected. A Theory of Change links inputs and activities to outputs, outcomes and long-term impact, and makes the assumptions visible.
We use the SDG Compass to map impacts across the value chain, from raw materials and suppliers to operations, distribution, product use and end of life, then prioritise the goals where you can make the biggest difference. Tools such as the SDG Action Manager, the B Impact Assessment and the Future-Fit Business Benchmark give structure and allow comparison with peers.
