This "Guide to Environmental Mentoring for Companies, Nonprofits, and Regulators" offers an overview and tools to help create or enhance programs that mentor companies on improving their environmental and financial performance. While the emphasis is on mentoring small and midsized companies, the guide may be useful for companies and organizations of any size. The 60-page guide includes a "Mentoring Toolkit" containing hands-on help and sample forms on developing a strategy, designing the program, selling the program, identifying and training mentors, being an effective mentor, and other aspects of the process. Also included are case studies of companies and other organizations that have established mentoring programs, along with additional resources.
