In October, sustainability consultant and former federal Green Party leader Jim Harris presented the business case for sustainability to delegates of the CIMA Canada Conference 2012. Mr. Harris put forward the argument that sustainable business practices weren’t just a matter of ethics, but also tools for cost reduction and profitability, citing several studies and examples that proved his thesis. However, he also noted that few organizations have adopted sustainability practices because the issue simply isn’t on their radar. He recently spoke with the Financial Post’s Dan Ovsey about why he believes this to be true and what he sees as the biggest barriers to sustainability. Following is an edited transcript of their conversation.
