Copenhagen is just days away, and the European Union isn't happy with the commitments on the table thus far. But Spiegel Online reports a new study suggests saving the climate would only cost Europeans two euros a day.

Combating Climate Change on the Cheap

Europe could save the planet for just €2 per person, per day!

What sounds like an infomercial is actually a study by the Stockholm Environment Institute and Friends of the Earth Europe. According to the study, released on Tuesday, the E.U. could reduce its emissions by 40 percent by 2020 and 90 percent by 2050, when compared to 1990 levels. That's twice the amount of reductions the E.U. has currently pledged ahead of Copenhagen.

However, as the study points out, such reductions won't come without a little sacrifice, aside from the €2 fee. Sacrifice number one: cars. The study calls for a reduction in trips taken by private cars to just 43 percent of total trips in 2050 from 75 percent in 2005. That means taking the train more. Additionally, the study calls on Europeans to use the train instead of the plane for trips of less than 1,000 kilometers (620 miles).

The study also asks meat eaters to go vegetarian, at least part-time. To reach such drastic reductions in carbon emissions, the average European would have to eat 60 percent less meat in 2020 compared to today. Such a diet would reduce the emissions that come from the animals and from fertilizing the crops those animals eat. It would also free up land currently used to raise livestock.
