The Future Laboratory created a ranking system in 2008 for three levels of sustainability that a company can achieve. The ranking system is called the Three Tiers of Sustainability. Tier1: The Basis of Sustainability
This is the first level of the three tiers and the most basic. A company knows what the chains of sustainability are and do small things around the office/company to minimize their cost. Examples of this may be turning off lights and appliances that are not being used; recycling of paper, bottles, or other items that can be recycled; and company carpools between coworkers to save on gas and help the environment. Tier 2: Thinking Sustainability
The second level of the three tiers, is the stage where the company has an understanding of what supply chain sustainability is. A company begins to find ways to try to incorporate sustainability into their daily operations. Examples of this can be finding ways to be more eco friendly, better product designs, and faster more efficient distribution of products/service. Tier 3: The Science of Sustainability
The third and last level of the Three Tiers of Sustainability is the stage when the company is aware of sustainability. In other words, they are no longer looking for ways to try to incorporate it into their production but are finding/using long-tern sustainability trends. A company is able to see that they are saving costs (ie. natural resources and money) when they use the methods and are trying to find trends that they can use from now on. This awareness gives clarity around the environmental impact of adjustments to supply chain agility, flexibility, and cost. Example of this are sustainability leaders will need to engage with external stakeholders such as competitors, NGOs and other organizations, and push for new practices that may be different than how the organization has conducted business in the past.
After a company implements the use of supply chain sustainability can start to reap in the benefits. A company has probably already started seeing some of these results with the decline of their costs and higher production of products. They may also begin to receive more customers who believe that this product/service is something that they may like to use, because it's environmentally friendly and probably cost effective towards their budget. Another benefit are enhanced profitability and shareholder value. At the same time, it can contribute to much needed economic and social development, and higher standards of living for millions of people.
