After defining global warming
in my previous blog, I felt it is necessary to look at what sustainability
means in practice and look at its history.
Sustainability – A Tricky Definition
Fien and Tilbury (2002) write
that sustainability is hard to define, due to the fact that sustainability and
its practices tend to be culturally constructed and there can often be hidden
agendas behind the definition. I found this was definitely the case when researching
the meaning of sustainability. This can be seen in the Ministry for the
Environment’s definition. The Ministry writes that sustainability is the
practice of “meeting the needs of today, without adversely impacting on the
needs of tomorrow” (Ministry for the Environment, 2013). On the surface this
definition would be considered broad, implying that we all have a part to play
in the process. However, after further reading, I found that the Ministry
focuses on the economic benefits of sustainability for businesses, choosing to
ignore why New Zealand, as a society, should implement sustainable practices. I
found this narrow minded. Given this, I chose to continue my search to find a
definition that focused more on why society as a whole, should practice
sustainability.
My search led me to a Youtube video defining sustainability. Although simplistic, I
believe it demonstrated a much more holistic perspective, stating that
sustainability is simply “allowing the world to continue to do what it was
designed to do” (RealEyesvideo, 2010). The video also defines four main “care
instructions” (RealEyesvideo, 2010) required to look after our planet. These
were to reduce our dependence on:
· Fossil fuels and heavy metals
· Synthetic chemicals that persist in nature
· Reduce destruction of nature
· Ensure we are not stopping people globally from
meeting their needs.
(RealEyesvideo, 2010)
If these factors are to be
considered, then is New Zealand achieving these targets?
A Brief History of Sustainability
Clark (2012) writes that the
debate over sustainable practices began to intensify in 1992, when the Earth
Summit was held in Rio de Janeiro. The
world leaders who contributed to the Earth Summit had the goal of “tying the
achievement of environmental sustainability with overcoming the interdependent
problems of poverty, illiteracy and militarism” (Clark, 2012). This made me
even more aware of how different my understanding is of why we practise
sustainability compared to the objectives of the leaders at the earth summit.
It also demonstrated again, that the agenda behind sustainable practices was,
like the Ministry of the Environment, being used for economic development
rather than for the preservation of our plant.
Then in 1997, the Kyoto Protocol
was signed by 55 developed countries, with the aim of reducing “total
greenhouse gas emissions of developed countries” (Ministry of the Environment,
2012). New Zealand had the target of reducing its emissions to the levels they
were in 1990. The New Zealand government also had the obligation to:
· Submit annual inventory of emissions
· Provide regular updates to national and regional
programmes, providing details on how to reduce emissions
· Adopt policies and measures provided by international
scientific and technical research and development.
(Ministry
of the Environment, 2010)
Since the signing of the Kyoto Protocol, the New
Zealand government has revised its target to reduce our carbon emissions by a
further 10 – 20% above those of 1990 by 2020. They state that they intend to
achieve this through three phases:
· Domestic emission reductions
· Storage of carbon in forests
· Purchase of emission reduction units in other
countries
(Ministry of the Environment, 2010)
After reading this plan set
out by the New Zealand government, I felt very positive in regards to the
commitment we were making towards sustainability and protecting our
environment. However, when reviewing figures published by Clark (2012),
on how countries are performing against their targets, it shows that New
Zealand is not meeting the agreement as set out by the Kyoto protocol. This is
a major concern and questions must be asked about the current government’s
commitment and obligations to sustainable practices.
