Return on Sustainability Investment (ROSI™) Methodology

ROSI is used by corporate leaders and investors to bridge the gap between sustainability strategies and financial performance.


Proving Sustainable Business is Good Business


Sustainability drives business and societal success, yet the challenge most businesses face is proving the monetary impact of their sustainability efforts as they seek to address environmental, social, and governance (ESG) related issues.

CSB has developed our Return on Sustainability Investment (ROSI) methodology to bridge the gap between sustainability strategies and financial performance, helping to build a better business case for both current and planned sustainability initiatives.



ROSI for Corporate Management and Investors


For corporate management, ROSI drives better-performing business - socially, environmentally, and financially - by embedding sustainability into core business strategy, decision-making, and accounting and quantifying the full range of costs and benefits, including intangibles.

For investors, ROSI improves decision-making, valuation, and communications - by better understanding ESG data, assessing where relative value exists in corporate strategies and investments, and better integrating, measuring, and reporting on financial performance driven by ESG strategies.
