Finally, chemical sector proxy data is frequently used in ecoinvent for bulk chemicals with good data availability, which can easily be replaced by more specific data, but the proxy approach is also applied for more specialized chemicals with poor data coverage. As ecoinvent is, in contrast to most commercial LCI databases, a not-for-profit project that relies on data contributions, the authors of the present study strongly urge any members of the scientific community and from industry to share better data and to thus improve the meaningfulness of ecoinvent data for all its direct and indirect users. Ultimately, the sharing of high quality data and basing the global decisionmaking on such data is at the core of ensuring the effectiveness of the decarbonization efforts of the chemical sector.
