From solar panels to company-wide recycling programs to supply chain decisions: green is here to stay. With today's emphasis on green investment, no longer is a company's reputational gain enough reward. For organisations making major investment in green projects, a measurement system showing return on investment - a scorecard that ensures ultimate accountability - is imperative. Yet until this point, no clear, reputable system of evaluation has been available. The Green Scorecard brings the authors' patented ROI methodology to this growing area of business, describing a systematic process with proven success across a variety of functions in the private and public sectors. The Green Scorecard provides organisations with a reliable method for determining which green initiatives will be most beneficial - a true antidote to 'green sky' thinking.
