We present a new approach for CO2 emissions appraisal: www.co2-tec.com is a tool providing details on CO2 emissions for full and partial loads, round trips and mixed laden transport units in multilevel transport chains including road transport.
Companies operating energy-intensive industrial facilities are already obliged to participate in the EU Emissions Trading Scheme (ETS). Despite the fact that traffic-related CO2 emissions account for 20 % of total CO2 emissions in the EU 27, only aviation will be integrated in EU ETS in the near future while road transport, contributing a rapidly growing share to overall CO2 emissions though, remains unconsidered. Whereas compensation of CO2 emissions from road transport is delayed by authorities, companies are starting to implement the concept of carbon footprints for their own organisation as well as for single products throughout entire supply chains. For this reason, logistics service providers need reliable methods for calculation of CO2 emissions to communicate related data to their customers. In order to provide accurate information for transport mode selection, routing and product related carbon footprinting from a logistics perspective, it seems more than vital to consider transport induced CO2 emissions in detail: As there are various concepts of emissions calculations and particularly different points of view as regards monetary assessments of those emissions a reliable calculation tool providing valid data is crucial.
The article presents a new and convincing approach for the appraisal of CO2 emissions caused by road freight transports: www.co2-tec.com is a tool developed by an Austrian consortium which provides detailed information on CO2 emissions for full and partial loads, round trips and mixed laden transport units transported by road in multilevel transport chains. The project is based on observations of varying business cases based on information commonly available at logistics service providers in order to model different types of transport chains. Every leg of the transport chain can be modelled separately by selecting multiple criteria such as type of lorry, load factor, empty trip ratio as well as number and weight of individual transport units. Distance calculation and visualization is based on the geographical information system PTV XServer to provide accurate door-to-door distances. Calculation of CO2 emissions is based on the Handbook Emission Factors for Road Transport (HBEFA 2.1) which covers different vehicle categories and multiple traffic situations.
Main future developments of www.co2-tec.com focus on integrating CO2 emissions of handling and storage processes to display total CO2 emissions in multilevel transport chains. In order to map intermodal transport chains and support transport mode selection CO2 emissions of other modes of transport shall be integrated as well.
