- Assumptions about input parameters that can result in variations in output values based on local circumstances for specific production.Review the existing emission factors derived from the key global sources, duly reflecting the scientific state of the art and ensuring the coverage of new and conventional fuels.
- Perform the gap analysis and develop emission factors for categories not yet covered, both for upstream and downstream emissions, taking into due consideration new production pathways, and addressing in particular the uncertainty and variation in the well to tank factors to be applied to the new fuels.
- Establish a clearer set of rules regarding:
- Methodology – to ensure that the basis and legitimate use of the two fundamental methodology types (consequential and attributional) are properly understood and applied appropriately.
- Boundaries of calculation – to ensure that boundaries are not accidentally or deliberately set in order to favour particular outcomes.
- Common sets of fuel / energy specifications – to ensure that data labels and associated values are truly aligned between sources.
- Assumptions about input parameters that can result in variations in output values based on local circumstances for specific production.
- The basis for new energy carriers to be calculated quickly and consistently in order to avoid delaying the deployment of new, beneficial solutions.
Establish a simple guidance to the transport sector as to which emission factors are the agreed defaults, and why; under what circumstances an alternative can legitimately be used.
The project’s main governance (e.g. Steering Group, Advisory Board) is expected to provide for direct involvement of all relevant stakeholders, as well as relevant European Commission services.
The proposal should build on the existing and emerging EU regulatory frameworks (including Commission’s proposal for the Fit-for-55 package and the new initiative on harmonised measurement of transport and logistics emissions – ‘CountEmissions EU’), GHG emissions accounting standardisation activities (such as the future ISO standard 14083) and other relevant initiatives and projects. Given that emission factors are applied in a global transport market, efforts need to be made to ensure that internationally relevant bodies such as IMO or ICAO are involved alongside prominent European stakeholders.
