摘要

Analysis based on the life cycle approach (LCA) is generally-accepted as an ideal approach for implementation of ecolabelhng scheme. The lack of an accepted methodology for LCA implementation, however, has retarded its widespread application and most major certification agencies still focus on the use and disposal of the product. The fundamental problem centers on the inherent difficulty in assessing and comparing different ecological impacts. It is difficult to compare a product which is biodegradable but produced in an energy intensive process with a product produced with less energy but has a half life of 5 million years. Although, in theory, LCA is acceptable, the controversy in successful implementation of eco labels in a broader spectrum of product is a major challenge.
