Emisiones de Emisiones de COCO2 debidas al transporte debidas al transporte marítimo marítimo de un producto: de un producto: una propuesta metodológica de cálculo una propuesta metodológica de cálculo

Abstract

We propose a methodology for calculating CO2 emissions from maritime transport of a product. The guide is useful for companies who want to know the carbon footprint of their products.We have reviewed the literature on methodologies for calculating CO2 emissions. The aim of methods found is, generally calculating emission inventories in a territory for a year. When attempted to adapt these methodologies to calculate emissions attributable to a particular product we found several difficulties related to the lack of information about the emission sources..The main contribution of this guide is that the calculation result is the amount emitted per unit of product following the principles of relevance, comparability, consistency, transparency and accuracy.Additional contributions of our guide are: easy to use, and is independent of the amount of CO2 emission sources.

The paper also shows the most critical aspects of the calculation and provides a guide to treat them properly. Finally we describe two cases of using the guide, by Autoritat Portuaria de Barcelona.
