NGVA's study 'Greenhouse gas intensity of natural gas' shows that natural gas reduces GHG emissions from passenger cars on a well-to-wheel (WtW) basis by 23% compared with petrol and by 7% compared with diesel. On the heavy-duty application, benefits compared to diesel are of 16% for CNG and up to 15% for LNG. Also in the maritime sector, overall WtW benefits are up to 21% compared to conventional heavy-fuel-oil (HFO) fuels. The use of renewable gas provides additional benefits towards carbon-neutral mobility: by blending natural gas with just 20% renewable gas, GHG emissions are reduced by 40% compared with oil-derived fuels.
NGVA Europe, the European Natural & Bio Gas Vehicle Association, has published its own study about the impact on the greenhouse gas (GHG) emissions from the use of natural gas as transportation fuel. The study has been commissioned to thinkstep, a leading global consultant and software company in the lifecycle analysis (LCA) domain, to perform an industry-wide assessment of the supply of natural gas to Europe and its use in the EU, mainly in the transportation sector. More than 50 companies from across the gas value chain took part in providing consistent, high quality data, referring to updated 2015 year figures and new technologies.
The report is intended to represent the new reference in the domain, providing a deep analysis of the GHG emission sources from the entire natural gas chain. This is fundamental in a transportation scenario asked to move from a long-stand system, mostly based on oil derived fuels, towards low carbon and clean solutions. Different technologies will have to be compared according to a technology neutral approach, needed for a fair market development, that will be guaranteed only through WtW methodology.
The study confirms that the use of natural gas represents one of the most effective solutions to fight climate change and improve air quality in a cost-efficient way. Thanks to both CNG and LNG, a wide range of transportation modes, from small passenger cars to long haul trucks can deliver a reduction in both GHG emissions and local pollutants reduction.
