I typed this several days ago but it did not appear?
B.C in 2008 used to import about 5% of their cement needs from asia and export far more to canada/U.S now they are importing around 20%. This is called carbon shedding:o. The rest of the cement industry among others, is also threatening to move. They are also using MORE petrol in 2010 than in 2008 so it's not helping there either.
