Abstract: To address the difficulties in acquiring, evaluating and maintaining LCA data, a transparent and fair LCA methodology was proposed herein. On the basis of state-of-the-art information technologies, automation, transparency and collaboration in acquistion, evaluation and maintainence of LCA data were achieved. On the basis of transparency, the contribution of related enterprises and individuals might be rewarded properly by the market, government and related enterprises. This mitigates the problems in acquiring, evaluating and maintaining LCA data, and propels the progress of green and sustainable manufacturing, as this topic requires further attention and support. Finally, the progresses of transparent and fair LCA methodology in China were analyzed, which indicates that this method develops rapidly and should be given great attentions and supports.
