Coming to the table seems pointless... so our big polluters will ignore whatever's being done, and the small polluters will simply close shop and pollute even more in China...
Which is just the way we like it.
We (USA, Europe, Australia, ...) currently live in a world-wide capitalist cycle, where those owning the means for production (China holds the baton now) set the rules, and where we've had generations of training to buy newer and cheaper, and the environmental cost has never been at issue. Perhaps China knows this better than anyone else, since they've ironically destroyed the solar manufacturing industry in the USA with US government grants, and without actually improving the technology. Refer Solyndra, among others.
While price remains the issue, there's no incentive for the purchaser to be environmental - be it a person, a company, or a nation.
China is going to be a bigger polluter than the USA? If global warming is a genuine problem for you, don't buy "Made in China". Don't buy a new iPhone, or a Philips CFL, or a pair of Levis 501s, or any paperback novels. Educate yourself and others; support local industry, local employment, and keep your money out of China. Despite what Fox screams, it's both patriotic and good for the planet!
It sticks it to those undercutting, polluting capitalists in China, who don't care about global warming. It also sticks it to those flag-waving patriots who outsource all responsibility (industry, jobs, knowledge, pollution, etc..) and keep the profits for no good cause... Yep, those evil Global Corporations.
But no, we keep buying room fans for $10 because they're a bargain, and new iPhones because they rock.
So governments charge local industry for greenhouse emissions, and landfill tariffs, and recycling fees, without changing consumer buying habits... Then everyone shakes their heads as local industry vanishes, but everyone buys Made in China because it's cheap.
So what matters to you? Do you really know enough about global warming to act differently to nearly every one of your compatriots? Or are you a sheep, cowed (heh) by generations of subservience to price?
Even if these kids get press coverage, nothing will change until we all learn how to pass up a bargain.
