It's disturbing that the EU wants to punish America and other countries for not jumping on the "Global Warming/Climate Change" bus yet. It has been consistently said that we lack enough information to definitively connect human activity to the 1 degree Farenheit (0.6 Celsius) increase in average temperature. Believe me, I'm not proud that Al Gore sold the world a doomsday movie based on exaggerations and outright lies (look it up, it's been proven by a UK court, so I've heard), and now that the Arctic ice has returned, we have not heard one word from our Nobel Prize swindler. Can we let science find out if we are threatened before we start to tank everyone's economy? (And does anyone know how to get the Nobel Society to revoke his award?)

Love the Smugness from the Euros. I'm all for EU trade embargoes. The US is overextended and needs to strengthens its domestic economy. BTW Eugene, check and see that the US is reducing CO2 emissions faster than Kyoto signatures.

All three presidential candidates, McCain, Clinton and Obama are much more environmental friendly than Bush. Next January Bush will be history.

The US has objected to unfair targets and will get on board when China and India have equal targets of compliance.

The EU should not risk upsetting the applecart. In a trade war of this magnitude - everybody loses - including airplane manufacturing jobs in Europe and access to cheaper goods made in China.

"It would be completely foolish for the Europe Union to export the pollution and the jobs because globally the effects on climate change will be just the same, only we lose the jobs and our industry.”

That is the exact reason that the US gave for not ratifying Kyoto, and the EU demonized them for that all these years. The EU also repeatedly stated that 'going green' would increase jobs, not export jobs.

So now the global warming scam artist are going to resort to black mail. Once a criminal mind always a criminal mind. There is no scientific proof of man made global warming, only poorly written computer models that are being proven wrong every day because mother nature is the biggest gorebull warming denier.

Looks like the proposed EU directive will cure the falling dollar.

CR, denver,

I guess the EU shredding a few decades of treaties covering trade isn't being "unilateral" then?

Although the same can't be said of China, the EU needs to sell stuff to the Yanks more than the Yanks need to buy it.

The EU (and everyone else on earth) has trade surpluses with the US. So threaten away! We Canadians can use the extra business.

The EU will really have to do better than threats to emerging economies,lets leave aside the USA for now what about China and India they argue that they must also be allowed to develope like other countries have and how they deal with polution is a major problem.Better we all try to find a way of caping those Chinese coal powered staions coming on line at the alarming pace of 2 per week!! so less postulating EU and more R&D to help those economies get greener rather than threats.

So much for America's holier-than-thou attitude. Come on, Uncle Sam, take your trousers to the laundry.

(No, not the Chinese laundry.)

After all the jobs have left Europe, at least we will have the satisfaction of knowing that our leaders were imagining that they were doing something useful.
