tailieunhanh - Life cycle assessment of supermarket carrier bags: a review of the bags available in 2006

This study assesses the life cycle environmental impacts of the production, use and disposal of different carrier bags for the UK in 2006. In recent years, the relative environmental impacts of lightweight carrier bags and other options has been debated. By the Spring of 20098 leading supermarkets had halved the number of single use carrier bags used. However, questions still remain about the environmental significance of lightweight carrier bags, especially with regard to the wider debate on global warming. . | Life cycle assessment of supermarket carrier bags a review of the bags available in 2006 Report SC030148 The Environment Agency is the leading public body protecting and improving the environment in England and Wales. It s our job to make sure that air land and water are looked after by everyone in today s society so that tomorrow s generations inherit a cleaner healthier world. Our work includes tackling flooding and pollution incidents reducing industry s impacts on the environment cleaning up rivers coastal waters and contaminated land and improving wildlife habitats.
