Companies producing biofuels have broadly cheered the introduction on Thursday of a certification system by the European Commission. The system is supposed to ensure that the industry doesn't lay waste to forests and drain peat lands or destroy other zones of environmental value.But the system does not yet include any criteria on emissions created when food crops have been displaced by fuel crops, or areas containing high stores of carbon-like grasslands, peat lands or forests are chopped down to produce food crops elsewhere.
