The issue
Duncan & Toplis aimed to take measurable and meaningful action by embedding Environmental, Social, and Governance (ESG) principles into its core strategy, making them a fundamental part of the organisation’s long-term vision and operational decision-making.
The challenges
Duncan & Toplis encountered complexity in gathering and analysing carbon data across their multiple office locations, each with different operational patterns and historical energy usage. They also faced the challenge of effectively aligning their ESG commitments with internal operations and communications, ensuring consistency between their public sustainability messaging and day-to-day business practices.
The solution
Duncan & Toplis conducted a comprehensive footprint analysis to establish their baseline emissions across all operations. They set specific net-zero targets with clear timelines and accountability measures. The firm invested in a solar panel rollout programme across suitable office locations to generate renewable energy on-site. They developed an integrated ESG strategy that connected environmental goals with their broader business objectives. Additionally, they implemented staff training programmes to build internal capability and engagement around sustainability initiatives.
The results
Duncan & Toplis earned certification as "On the Road to Net Zero," validating their systematic approach to carbon reduction. Their investment in renewable energy infrastructure resulted in over 73,000 units of renewable energy generated. The firm successfully launched ESG-aligned operations across their business, embedding sustainability considerations into their service delivery and internal processes. These efforts have strengthened their market position as sustainability leaders within the regional accountancy sector.
