This document summarizes a workshop on sustainability for CFOs. It discusses how sustainability can deliver long term value to businesses. Key areas that sustainability addresses are a company's energy usage, CO2 emissions, supply chain management, waste reduction, and travel policies. Costs associated with sustainability include infrastructure updates, personnel for processes and auditing, and increased supplier costs. The business case for sustainability is justified by potential cost savings, compliance, attracting investment, improved employee morale, brand benefits, and gaining competitive advantage by meeting customer demands. CFOs should consider both near term benefits and long term value, and how sustainability improves competitive advantage versus maintaining parity with competitors.
