Greenergy CSR policy, October 2017

This document outlines our commitment to act ethically and responsibly, defined through our values.


Combined with an entrepreneurial approach and a can-do attitude, we create straightforward outcomes for the most complex issues.

Through transparency, competitive pricing and efficiency, we can continue to deliver a compelling offer to new and our long-term customers.

Some examples of this approach are:

Innovate. Opening a new supply platform in Canada has created opportunities for growth.

Improve. Continually enhance our manufacturing process to make biodiesel from increasingly diverse sources of waste oils.

Adapt. Taking redundant refinery infrastructure, adapt it and create modern fuel terminals that meet the current and future needs of customers.
