Services for sustainable businesses

Executive Education


We provide C-level and department head education and discussion about practical and profitable strategies for sustainability and competitive advantage.   Learn how to increase the top line AND the bottom line and improve staff competence, productivity and morale.  Principal consultant Burt Hamner has trained over 5000 managers in 15 countries in practical leadership and staff development for Triple Bottom Line results.  It works in Malaysia and Ecuador, it will work for you.   Our first meeting with the executive team is free and will explore your concerns, possible solutions and options for engagement.

Business Sustainability Assessment


We work with your team to assess the business operations at all levels to find the points of leverage and highest impact.  We map out key business processes, for example the supply chain, to build a chart of accounts that will drive sustainable performance.

Sustainable Accounting and Investment Analysis


When we know where to get the right data we can start accounting for it properly.  Poorly designed accounting systems actually subsidize waste and pollution and drive unsustainable activities!   You can account for and drive sustainable quality management.
