LCA activities in Thailand

Abstract

Life Cycle Assessment (LCA) has been introduced to Thai industries in 1997 as one of the ISO 14000 series. The concept of LCA is being gradually accepted. However, there are few formal LCA studies in Thailand so far due to a limited number of LCA experts and a lack of sufficient databases relevant to domestic conditions. The LCA activities in Thailand can be divided into 3 areas, which are (1) Workshops and seminars (2) Use of LCA studies in Ecolabelling and (3) Life Cycle Inventory (LCI) and LCA studies. The first LCI study was to develop LCI data for Thailand Electricity Grid Mixes. There are a few LCA thesis studies in some universities, but these studies used databases from commercial software programs. The study and use of LCA may increase in the future only if domestic background database will be provided by research institutes and the government, and if industry understands LCA methodology through periodical workshops and seminars. INTRODUCTION Life Cycle Assessment has been introduced to Thai industries in 1997 as one of the ISO 14000 series. The concept of LCA is being gradually accepted. However, there are few formal LCA studies in Thailand so far due to a limited number of LCA experts and a lack of sufficient databases relevant to domestic conditions. ACTIVITIES The LCA activities in Thailand can be divided into 3 areas including (1) Workshops and seminars (2) Use of LCA studies in Ecolabelling and (3) Life Cycle Inventory (LCI) and LCA studies. 1. Workshop and Seminar To introduce the LCA concept to Thai Industries, the Thailand Environment Institute (TEI), in cooperation with many organizations, organized LCA seminars/workshops in Thailand annually between 1997-2002. All seminars successfully gained attention from Thai industry and educational institutes. The Thailand LCA Forum (http://doi.eng.cmu.ac.th/Thailca) has been launched by TEI in January of 2002. 2. Use of LCA studies in Ecolabelling The Green Label project was initiated in October 1993 by the Thailand Business Council for Sustainable Development (TBCSD) in association with the Ministry of Industry. This project is supported by the Secretariat, which is formed by a partnership between the Thai Industrial Standards Institute (TISI) and TEI. The objectives of the project are to establish the product criteria and award certification to specific products that are shown to have less impact on the environment, when compared with other products serving the same function (not including foods, drinks, and pharmaceuticals). The project came about from the idea that the green label can stimulate market choice thus encouraging producers to improve the environmental quality of their products and services in response to consumer demand. Award of the Thai Green label is based on the product criteria developed by a technical subcommittee. The subcommittee consists of representatives from the scientific, business and environmental groups and others if appropriate and available. A new subcommittee is established for each selected product category. At present, there are 29 product categories that are eligible for the Thai Green Label, and up to the end of November 2001, 227 individual products have received the Green Label award. Being aware of the high cost involved and time consumed in developing product criteria through format LCA, the Thai Green Label scheme has decided that a full quantitative LCA is not applicable for setting criteria for all products, especially in developing countries. The development of award criteria for the scheme has followed different methodologies. It will take into account not only significant environmental impact during the life cycle of the products (Life Cycle Consideration: LCC), but also capability to meet proposed criteria with reasonable process modification and/or improvement. The availability of testing institutes and the ability to perform tests are considered carefully, while setting the criteria. Results from existing LCA studies have been used as a scientific tool in the Thai Green Label Scheme for the development of environmental criteria for a few product categories. 3.
