Burning issue


What on earth is Donald Holliday on about (NCE letters last week)? Has he not realised that it is only the burning of fossil fuels, newly released from the bowels of the earth, that exacerbates the greenhouse effect?

Biomass and landfill gas, therefore, will reduce carbon emissions when used as alternatives to fossil fuels. The burning of biomass simply recycles carbon products that are already in the surface environment, while the burning of land fill gas (methane) converts this back to CO 2, which is only one-10th as potent as a greenhouse gas.

If so-called informed civil engineers cannot grasp these basic environmental concepts, what hope for the rest?
