An excellent new paper busting the myths and summarising what Australia and NSW should be doing on climate change.
‘Clean coal’ and other greenhouse myths
Quote: "What is needed above all is a near-term
policy that causes emissions to peak in the next
few years then fall over the
next decade. If we succeed in that, the future will take care
of
itself."
Summary:
There is no longer any doubt that rising concentrations of greenhouse gases
are leading
to dangerous change in the global climate. In Australia, public
and political opinion
finally shifted in late 2006, with record droughts and
an early start to the bushfire
season. The Stern Review in October 2006 and
the Fourth Assessment Report of the
Intergovernmental Panel on Climate Change
in February 2007 reinforced fears about
global warming.
The debate has now
shifted to the best means of reducing greenhouse gas emissions,
and to the
need for adapting to the level of climate change that now appears
inevitable.
Not surprisingly, the confusion and deliberate misinformation
which formerly
surrounded the debate on climate change has now shifted to the
debate on how to tackle
it. If there is to be an effective response (and the
odds do not look good at present) very
large changes are required in the
global economy, and especially the global energy
system. There will be both
winners and losers among industries and companies. The
potential losers are
fighting to retain their advantages and privileges. Others are
positioning
themselves to profit, in some cases from ineffective or even
counterproductive
‘solutions’.
Part of the strategy of potential losers
and winners is to influence the public debate
through myths and half-truths.
Governments and oppositions are also attracted to
convenient half-truths to
mask inaction or lack of effective policy. Even among the
many who sincerely
support a reduction in emissions, there is much confusion.
The scope for
misinformation is especially high in 2007, with climate change already
a
major issue for the Federal election later in the year. This paper
addresses some of the
most widely repeated myths about reducing emissions,
which are sure to get a thorough
workout in the coming months. The 16 most
common myths are as follows.
1. Coal can be part of the
solution. In reality, coal is the main problem, and
curtailing its use is
essential. There is no such thing as ‘clean coal’ at present,
and there is a
chance there will never be.
2. Carbon sequestration can be the centrepiece of
policy. This technology is
unproven and expensive.
3. Nuclear power can be
the centrepiece of policy. This technology is expensive
and risky and, if
pursued, is unlikely to have any significant impact for 15-20
years.
4.
Renewable energy is always benign. All forms of energy have advantages
and
disadvantages, and not all renewables are completely ‘clean’.
5.
Renewable energy can support our current level of energy use. In reality,
we
cannot make the transition to a renewable energy system without first
relying on
natural gas and greatly increasing the efficiency of energy
use.
6. Renewable energy cannot provide baseload power. An electricity system
that
uses a mix of geographically dispersed renewable technologies, with some
gasfired
power and energy storage, will have just as much ability to supply
reliable
baseload power as the current coal-based generation system.
7.
Voluntary ‘greenpower’ schemes can make a difference. Experience shows
that
they have had little effect.
8. Buying carbon offsets is the same as actually
reducing emissions. In fact,
buying offsets is too often just a smokescreen
for large emitters who intend to
operate on a ‘business as usual’ basis. A
reduction in emissions requires a
reduction in emissions, plain and
simple.
9. We can plant enough trees to get us out of trouble. We
can’t.
10. We need to wait for new technology. In reality, if the technology
is not already
available, it will come too late.
11. The hydrogen economy
will save the day. Energy is required to produce
hydrogen, so the hydrogen
economy would be only as greenhouse friendly as the
energy system which
supports it.
12. Expanding public transport is the answer. Cars are here to
stay and reducing
emissions from them must be the primary focus of
policy.
13. It won’t cost anything. Tackling climate change will mean the end
of the era of
cheap energy.
14. Higher energy prices mean lower living
standards. In fact, with good policies
energy bills could come down while
energy prices go up.
15. Australia will meet its Kyoto target. We
won’t.
16. There is no point ratifying the Kyoto
Protocol. Australia’s interests would be
best served by having a seat at the
table. The G8 summit endorsed the Kyoto
process under the UNFCCC.
This
paper exposes these greenhouse myths, and reiterates the basic principles of
an
effective greenhouse policy:
· no new coal-fired generation until it
meets the criteria for at least half-clean use;
· encouragement of renewable
and gas-fired generation;
· an increasingly stringent cap on emissions
supported by a tradeable permit
system; and
· stringent minimum energy
efficiency standards for vehicles, buildings and
appliances.
In the
meantime, Australia’s emissions continue to rise inexorably, despite the outlay
of
considerable amounts of private and public money, most of which has been
wasted.
What is needed above all is a near-term policy that causes emissions
to peak in the next
few years then fall over the next decade. If we succeed
in that, the future will take care
of itself.
