For one, the EF database (there is no plural) does not fit to the CML LCIA method, and CML does not have weighting, second, you can of course still calculate even without normalisation and weighting, only the weighting is not available, and third, the EF database we distribute has normalisation and weighting (for the EF LCIA method, for the main categories, for others it is not provided and available from the EC) -> ?
