 However, in a Statement of the Area address on 21 November 2006, the Leader of Tameside Council announced that 4,500 trees had already been planted, increasing to 10,000 to compensate for the loss of trees when the bypass is built and to help mitigate the increases in CO2 emissions.The council leader also claimed that each tree planted would offset 75 kg of CO2 per annum.This figure—for trees to be planted in northern England—is 3.5 times greater than that for trees planted in tropical rainforests.
