Paul Krugman says that if we want to save the planet from global warming, China's participation will be required:
Empire of Carbon, by Paul Krugman, Commentary, NY Times: I have seen the
future, and it won’t work.
These should be hopeful times for
environmentalists. Junk science no longer rules in Washington. President Obama
has spoken forcefully about the need to take action on climate change; the
people I talk to are increasingly optimistic that Congress will soon establish a
cap-and-trade system... And once America acts, we can expect much of the world
to follow our lead.
But that still leaves the problem of China, where I
have been for most of the last week. Like every visitor to China, I was awed by
the scale of the country’s development. Even the annoying aspects — much of my
time was spent viewing the Great Wall of Traffic — are byproducts of the
nation’s economic success.
But China cannot continue along its current path
because the planet can’t handle the strain.
The scientific consensus on ... global warming has
become much more pessimistic over the last few years. ... Why? Because the rate
at which greenhouse gas emissions are rising is matching or exceeding the
worst-case scenarios. And the growth of emissions from China ... is one main
reason for this new pessimism.
China’s emissions, which come largely from its
coal-burning electricity plants, doubled between 1996 and 2006. ... And the
trend seems set to continue: In January, China announced that it plans to
continue its reliance on coal... That’s a decision that, all by itself, will
swamp any emission reductions elsewhere.
So what is to be done about the China problem?
Nothing, say the Chinese. Each time I raised the
issue..., I was met with outraged declarations that it was unfair to expect
China to limit its use of fossil fuels. After all, they declared, the West faced
no similar constraints during its development; while China may be the world’s
largest source of carbon-dioxide emissions, its per-capita emissions are still
far below American levels; and anyway, the great bulk of the global warming that
has already happened is due not to China but to the past carbon emissions of
today’s wealthy nations.
And they’re right. It is unfair to expect China to
live within constraints that we didn’t have to face when our own economy was on
its way up. But that unfairness doesn’t change ... that letting China match the
West’s past profligacy would doom the Earth as we know it.
Historical injustice aside, the ... climate-change
consequences of Chinese production have to be taken into account somewhere. And
anyway, the problem with China is not so much what it produces as how it
produces it. ...
The good news is that the very inefficiency of
China’s energy use offers huge scope for improvement. Given the right policies,
China could continue to grow rapidly without increasing its carbon emissions.
But first it has to realize that policy changes are necessary.
There are hints ... that the country’s policy
makers are starting to realize that their current position is unsustainable. But
I suspect that they don’t realize how quickly the whole game is about to change.
As the United States and other advanced countries
finally move to confront climate change, they will also be morally empowered to
confront those nations that refuse to act. Sooner than most people think,
countries that refuse to limit their greenhouse gas emissions will face
sanctions, probably in the form of taxes on their exports. They will complain
bitterly that this is protectionism, but so what? Globalization doesn’t do much
good if the globe itself becomes unlivable.
It’s time to save the planet. And like it or not,
China will have to do its part.
