Table 9 compares our results with those derived from LCA for the same cases. Compared with the range of estimates for renewable energy listed in Table 7, the difference between our method and LCA is small and could be attributed to different assumptions and the choice of emission factors used in the calcu- lation. Emission factors embedded in LCA are mostly European or Danish averages, therefore representing state-of-the-art wind power technologies. Our choice of emission factors is based on the international default values recommended by IPCC, which are always higher than LCA’s. The methods used in this study are general but simple and can directly present emissions from different material consumption and from different phases.
