Abstract
Eurac Research aims to include in the PIS system a CO2 emissions calculator for business travel with the objective of making collaborators conscious of the environmental impact of their activities. The overall aim is to raise the environmental awareness of Eurac Research’s collaborators and to collect data to be used to inform strategies to reduce the carbon footprint of Eurac Research activities. Within the Institute for Renewable Energy (RENENE), the Urban and Regional Group has already started working on a similar project gathering information and expertise. In light of this, it has been agreed that RENENE will conduct further research to identify the most relevant CO2 accounting methods and to collect relevant data to perform the analysis. For this purpose, existing GHG accounting standard and methodologies have been reviewed, current datasets for calculating individual travel emissions compared, and a set of emission factors selected. The selected data have been chosen based on the transparency, consistency, comparability, completeness, and accuracy of the dataset. The document is organized as follow: Chapter 2 sets the historical context and identifies the main existing methodologies. It then illustrates our approach and provides the first feedback on the existing PIS system. Chapter 3 contains a brief description of the tool and methods identified, while chapter 4 contains the reference to specific datasets. Finally, chapter 5 summarises the conclusion and reports the selected data to be used in the PIS system to calculate the CO2 emissions of Eurac Research’s business travels
