There are many different definitions of sustainability.

One of the most-used definitions is by the  World Commission on Environment and Development.

They define sustainability or sustainable development as "forms of progress that meet the needs of the present without compromising the ability of future generations to meet their needs." This definition argues for the rights of future generations to raw materials and vital ecosystem services to be taken into account in decision making.

More simply, BTL thinks that being sustainable is about “being able to continue in the long term”. This is something that all businesses are focussed on and is not just about “being green”.

Being sustainable is also about adapting to changes in the market, recruiting, training and retaining new staff and skills, and delivering a competive product or service.

As resources, energy, and water become more expensive, and the cost of managing waste increase, understanding, managing and reducing these costs will not only improve competitiveness, but will position your business in a new market where customers are increasingly looking for a more sustainable product or service.

Being able to demonstrate that your business has reduced its environmental impact, will increase the support of the local community, and help attract new skills and staff to your business. There are hundreds of different definitions of sustainability.
