The answer is no, they are not interchangeable. The term “green” connotes
short-term efficiencies, such as switching from regular to LED light
bulbs, whereas sustainability means long-term effectiveness. Solar
Energy is sustainable. Wind power is sustainable. These
forms of energy are naturally replenishing, not depleted.
Norman Christopher, director of sustainability for Grand Valley
State University, illuminated the concept of sustainability with
the following quotes:
“[Sustainability is] meeting the needs of today without comprising
the ability of future generations to meet their own needs.”
( U.N. Brundtland Report 1987)
We do not inherit the earth from our fathers, we borrow it from
our children.
– Ancient Indian Proverb
How does the concept of sustainability translate into real life,
into municipal life? Sustainable communities embrace the principles
of sustainable development by being:
Active, inclusive, and safe
Well run
Environmentally sensitive
Well designed and built
Well connected
Thriving
Well served
Fair for everyone
You can’t have sustainability without attention to the environment,
economics, and social justice. This is the triple bottom-line. Christopher
gave examples of how the city of Grand Rapids works sustainable goals
into the overall management of its city. For instance, the
city has a goal to reduce water consumption by 15 percent by 2015,
to purchase 20 percent renewable energy by 2008, and to reduce City
CO2 emission by 7 percent by 2012. Further, a measurable objective
toward the city’s goal of economic prosperity is to build a
new economy with a highly skilled workforce by 2015, and to establish
a sustainable purchasing system by 2008. Lastly, to build toward
a goal of social justice, the city’s objective is to reduce
illiteracy by 50 percent by 2014, have all third grade students in
Grand Rapids Public Schools reading at grade level by 2010, and to
end homelessness by 2014.
Christopher calls the combination of environmentalism, economics,
and social justice the triple bottom line. It is the core,
or foundation of a sustainable community. You can’t
have a sustainable community without concentrating on all three areas.
