Many transport companies offer CO2 monitoring as a (paid) service. Surprisingly, the outcome of this monitoring can often be quite different for the same shipment at another transport company. Often, there is a lack of insight in the calculations behind the monitoring. This has led to some European government initiatives to create reliable monitoring. This means a thorough analysis of the actual performance of any company, working with fixed standards.
The next step will be an official certification of the CO2 footprint of any company, even going so far that accountants will need to sign; and in future possible CO2 tax being introduced. In the light of these developments, the industry associations are coordinating their efforts to create a high quality CO2 monitoring that will meet the future standards.
To conclude, it starts with learning more and analysing what is the most interesting part for you. Members of your national industry association receive free support. Also, all the initiatives are in the hands of a number of selected logistic companies, which are operating under the collective umbrella of the associations. Hands on support is also available to help you with your set up.
