Carbon Correction Factor Called for by European Energy and Transport Associations

NGVA_EUROPE_LOGOEurope’s energy and transport industry is calling for implementation of a Carbon Correction Factor (CCF) to be included in the European Parliament vote on CO2 emission standards for new passenger cars and light commercial vehicles.

In view of the European Parliament plenary vote on Wednesday 3rd of October, the European Biogas Association (EBA), EUROGAS, Gas Infrastructure Europe (GIE) and the Natural & bio Gas Vehicle Association (NGVA Europe) jointly underline the importance of natural and renewable gas as pragmatic solution to quickly start the decarbonisation process and tackle air quality issues in urban areas of passenger vehicles. Today, the previously mentioned associations published and sent a joint letter to the EU institutions.

Well-to-Wheel Approach Will Level Playing Field

Following the Paris agreement, the CO2 emissions standard regulation for passenger cars and light duty vehicles needs to be updated. A Well-to-Wheel approach needs to be implemented in order to be in measure to assess the GHG emissions from future combinations of vehicle technologies and fuels.

“We are addressing future technologies with the wrong tool: tailpipe CO2emissions measurement does not express anymore, neither vehicle’s efficiency on hybrid architectures, nor climate change impact when renewable fuels are used” – Andrea Gerini, Secretary General of NGVA Europe.

For this reason, it is crucial to amend the current proposal of the Regulation to include the benefits from the use of renewable gas and, more generally, from renewable fuels in road vehicles.

Carbon Correction Factor

The proposed amendment, the implementation of the Carbon Correction Factor – CCF – is a pragmatic transparent way towards a Well-to-Wheel approach.

The Carbon Corrector Factor does not bring any ‘double counting’, but it solves the limitation of the current methodology (tailpipe emissions measurement) which does not distinguish the origin of the fuel. The associations are not seeking inappropriate advantage through this proposed methodology; they are instead asking the Parliament to recognise and insert a realistic measurement of emissions into legislation.

“We need to consider all effective solutions if we want to start to significantly curb CO2 emissions from the transport system from today and to keep a technology neutral approach to decarbonize system”, Andrea Gerini said.

NGVA Europe Study

In 2017, NGVA Europe, supported by a wide partnership of industry organisations, commissioned the leading global consultant and software company in the Lifecycle Analysis (LCA) domain, thinkstep, to perform an industry-wide analysis of the supply and use of natural gas in Europe, not only with regard to road vehicles (Well-to-Wheel) but also including maritime vessels (Well-to-Wake) and power generation (Well-to-Grid).

It found that, considering the overall Well-to-Wheel (WtW) impact, there are significant benefits and reduced GHG emissions from passenger cars as well as light and heavy-duty vehicles when switching to CNG or LNG from petrol and diesel.

For passenger cars, on a WtW basis, natural gas reduces GHG emissions by 23% compared with petrol and by 7% compared with diesel.

In heavy-duty applications, benefits compared to diesel amount to 16% for CNG up to 15% for LNG.

In maritime applications, the use of LNG provides an overall Well-to-Wake benefit up to 21% compared with conventional HFO (Heavy-Fuel Oil) fuels.
