What is sustainability?

Sustainability has many definitions, but the most common is that sustainability is development that satisfies the present needs without hindering the ability of future generations from meeting their own needs.

Great Northern Insulation is working with an international not-for-profit organization called The Natural Step,  who are dedicated to creating a sustainable society. We use the sustainability principles that have been advanced through the teamwork of scientists internationally over the last 20 years as guiding factors in decision making here at GNI.

These principles are that for a society to be sustainable, nature is not exposed to continuously increasing…

amounts of materials culled from the Earth's crust (such as fossil fuels and heavy metals)

amounts of society produced substances (such as VOCs, CFCs, dioxins, etc.)

the ongoing physical degradation of nature


and, in a sustainable society...people are not faced with conditions that continuously impair their ability to meet their needs.

GNI sustainabilityWhy does sustainability matter?

However sustainability is defined, the one thing that is true is that there is a vital need for all of us to address its challenges. Currently, we are living beyond the planet's means to support us and the result is that ecosystems are being run down, resources are disappearing and waste is accumulating in the air, land and water. In the end, finding solutions to these issues will transform the ways that we all work, live, and compete.

How does sustainability affect me

The computer you are using is made from a combination of metals, plastics, and other materials which all ultimately come from resources derived from nature. Our choices to buy, use, or throw away products all have an effect on nature. This also means that as a consumer you have the power to affect change through making better choices each and every day.

"Because we don't think about future generations, they will never forget us."

– Henrik Tikkanen
