Double Materiality Workbook

The Double Materiality Workbook for Small Businesses

Find the sustainability issues that matter most to your business, and turn them into action, in days not months.

Customers, investors and talented people increasingly want to know what your business is doing on sustainability. But where do you start? A double materiality assessment answers that question by looking at two things: how your business affects people and the planet, and how sustainability issues affect your business. It tells you where to focus your time and budget, and what you can safely park.

This workbook guides you through the whole process, step by step. It's built by an ESG strategy specialist for small businesses that want a credible, practical approach without the consultancy price tag.

What's inside

• 17 core sustainability issues across Planet, People and Prosperity, based on the SASB Standards and cross-referenced to GRI and the latest B Corp standards.
• A plain-English Issue Guide explaining what each issue covers, with a prompt to help you score it.
• A clear scoring guide, so your scores are consistent and easy to explain.
• Practical guidance on choosing your scorers and bringing in the views of customers, suppliers and your community.
• Space for up to three people to score, with automatic averages and a flag wherever your team disagrees, which is perfect for a workshop.
• A materiality matrix and top priorities list that build themselves as you score, clearly showing your Top and second-tier priorities, ready to save as an image for your impact report or to share with stakeholders.
• An action planner with progress tracking, plus worked examples to get you started.
• Clear next steps on how to prioritise, share and review your results.

Who it's for

Small and medium-sized businesses that want to understand and improve their impact, support their B Corp journey, respond confidently to customer questionnaires, or simply get their sustainability priorities straight.
