But at least almost everyone now agrees that
we must act, if not at the necessary speed. If we're to have a
high chance of preventing global temperatures from rising by 2C
above pre-industrial levels, we need, in the rich nations, a 90%
reduction in greenhouse gas emissions by 2030(1). The
greater part of the cut has to be made at the beginning of this
period. To see why, picture two graphs with time on the horizontal
axis and the rate of emissions plotted vertically. One falls like
a ski jump: a steep drop followed by a shallow tail. The other
falls like the trajectory of a bullet. To the left of each line
is the total volume of greenhouse gases produced in that period.
They fall to the same point by the same date, but far more gases
have been produced in the second case, making runaway climate
change more likely.
So how do we do it without bringing civilisation
crashing down? Here is a plan for drastic but affordable action
the government could take. It goes much further than the proposals
discussed by Tony Blair and Gordon Brown yesterday, for the reason
that this is what the science demands.
- Set a target for reducing greenhouse gas emissions
based on the latest science. The government is using outdated
figures - restated by Blair and Brown yesterday - aiming for a
60% reduction by 2050. Even the annual 3% cut proposed in the
early day motion calling for a new climate change bill does not
go far enough. Timescale: immediately.
- Use that target to set
an annual carbon cap, which falls on the ski jump trajectory.
Then use the cap to set a personal carbon ration. Every citizen
is given a free annual quota of carbon dioxide. He spends it by
buying gas and electricity, petrol and train and plane tickets.
If he runs out, he must buy the rest from someone has has used
less than his quota(2). This accounts for about 40%
of the carbon dioxide we produce. The rest is auctioned off to
companies. It's a simpler and fairer approach than either green
taxation or the Emissions Trading Scheme, and it also provides
people with a powerful incentive to demand low-carbon technologies.
Timescale: a full scheme in place by January 2009.
- Introduce a new set
of building regulations, with three objectives. A. Imposing strict
energy efficiency requirements on all major refurbishments (costing
£3000 or more). Timescale: comes into force by June 2007.
B. Obliging landlords to bring their houses up to high energy
efficiency standards before they can rent them out. Timescale:
to cover all new rentals from January 2008. C. Ensuring that all
new homes in the UK are built to the German passivhaus standard
(which requires no heating system). Timescale: comes into force
by 2012.
- Ban the sale of incandescent
lightbulbs, patio heaters, garden floodlights and several other
wasteful and unnecessary technologies. Introduce a stiff "feebate"
system for all electronic goods sold in this country. The least
efficient are taxed heavily while the most efficient receive tax
discounts. Every year the standards in each category rise. Timescale:
fully implemented by November 2007.
- Redeploy the money
now earmarked for new nuclear missiles towards a massive investment
in energy generation and distribution. Two schemes in particular
require government support to make them commercially viable: very
large wind farms, many miles offshore, connected to the grid with
high voltage direct current cables; and a hydrogen pipeline network
to take over from the natural gas grid as the primary means of
delivering fuel for home heating. Timescale: both programmes commence
at the end of 2007 and are completed by 2018.
- Promote the development
of a new national coach network. City centre coach stations are
shut down and moved to the junctions of the motorways. Urban public
transport networks are extended to meet them. The coaches travel
on dedicated lanes and never leave the motorways(3).
Journeys by public transport then become as fast as journeys by
car, while saving 90% of emissions. It is self-financing, through
the sale of the land now used for coach stations. Timescale: commences
in 2008; completed by 2020.
- Oblige all chains of filling stations to supply
leasable electric car batteries. This provides electric cars with
unlimited mileage: as the battery runs down, you pull into a forecourt.
A crane lifts it out and drops in a fresh one. The batteries are
charged overnight with surplus electricity from offshore windfarms.
Timescale: fully operational by 2011.
- Abandon the road-building and road-widening
programme, and spend the money on tackling climate change. The
government has earmarked £11.4 billion for new roads(4).
It claims to be allocating just £545 million a year to "spending
policies that tackle climate change"(5). Timescale:
immediately.
- Freeze and then reduce
UK airport capacity. While capacity remains high there will be
constant upward pressure on any scheme the government introduces
to limit flights. We need a freeze on all new airport construction
and the introduction of a national quota for landing slots, to
be reduced by 90% by 2030. Timescale: immediately.
- Legislate for the closure
of all out-of-town superstores, and their replacement with a warehouse
and delivery system. Shops use a staggering amount of energy (six
times as much electricity per square metre as factories, for example),
and major reductions are hard to achieve: Tesco's "state
of the art" energy-saving store at Diss has managed to cut
its energy use by only 20%(6). Warehouses containing
the same quantity of goods use roughly 5% of the energy(7).
Out-of-town shops are also hard-wired to the car - delivery vehicles
use 70% less fuel(8). Timescale: fully implemented
by 2012.
These timescales might seem extraordinarily
ambitious. They are, by contrast to the current glacial pace of
change. But when the US entered the second world war, it turned
the economy around on a sixpence. Carmakers began producing aircraft
and missiles within a year, and amphibious vehicles in 90 days,
from a standing start(9). And that was 65 years ago.
If we want this to happen, we can make it happen. It will require
more economic intervention than we're used to and some pretty
brutal emergency planning policies (with little time or scope
for objections). But if you believe these are worse than mass
death, there is something wrong with your value system.
Climate change is not just a moral question:
it is the moral question of the 21st century. There is one position
even more morally culpable than denial. That is to accept that
it's happening and that its results will be catastrophic; but
to fail to take the measures needed to prevent it.
