I don’t actually see the problem here if the EU includes agriculture within their carbon reduction schemes and removes subsidies which makes their products artificially cheaper to produce than ours. The only problem is that they haven’t as yet done either of those things, which would provide even more impetus for our government to work with developing countries in the WTO in order to liberalize the agricultural markets in the United States and Europe.

In order to achieve an average 10% reduction of greenhouse gases from sectors not covered by the ETS, such as transport, buildings, agriculture and waste by 2020, the Commission has set national targets according to countries’ GDP.

Even if the carbon schem were implemented here to the extent that the Greens demand its unlikely to work, at least in regards to changing peoples behaviour. You only have to look at the current petrol consumption, which has remained steady, rather than declining as you would have expected, despite the record high petrol prices.

Every industrial nation is completely hypocritical in regards to carbon emissions. For example Germany has exempted COAL POWER PLANTS from the scheme. Their claim to lead the way in the fight against climate change is as bogus as Helen Clark’s award from the UN.

“But with Germany wanting to exempt coal (!) and the United Kingdom probably emitting about 92 percent more methane than it declares on top of the price tumble of late April, Kyoto doesn’t seem to be working.”
