In this paper we empirically assess and compare the environmental impact of pesticide programs for Bt, Ht (glufosinate) and conventional corn in Europe, employing the Environmental Impact Quotient. We use field trial data from Narbons, France 2004 as well as secondary data. Our results show that management of Bt corn has a lower environmental impact than conventional corn programs. Herbicide treatment of the Ht variety also has a much lower environmental impact than that of the two conventional programs. Our empirical findings support the argument of lower environmental and health impacts with respect to pesticide use when growing Bt and Ht corn. The outcomes are relevant for environmental benefit-cost analysis of Bt and Ht corn.
