Ecological accounting

The most important result obtained on this front bears on the quantification of the errors associated with the national road freight transport database (SITRAM). This database is informed year by year through a dedicated sampling campaign, but the errors associated with the various types of material goods transported have never been quantified. This was achieved by our team through the use of appropriate error estimators. This result is eagerly awaited by a number of scientific teams and public territorial agencies. Furthermore, the methodology that we have developed can easily be transposed to other countries. This result constitutes an important piece in the overall effort that the team has devoted to the question of the quantification of uncertainties in material flow analyses. This work is in the press in the leading journal in this field, the Journal of Industrial Ecology.
