As a director of sustainability, your role is to create company policies that impact your organization's environmental sustainability standards. Your responsibilities in this role revolve around ecology and how your company can lower its pollution of the environment surrounding it. You may create a new policy that helps to monitor this impact, or you may change existing policies to do the same. Your duties involve increasing the sustainability of the organization as a whole, from manufacturing processes, to supply chain, and all the way through to customer service and technology. You are the expert in sustainability and the go-to for individuals inside and outside the company with questions on the subject.
