GASNAM presented its document “Natural gas guarantees air quality” as a way of announcing proposals and recommendations based on natural gas as an available, economic and alternative fuel for urban mobility. It is a detailed study of the proposals made by the City of Madrid, indicating solutions available using the consolidated technologies offered by natural gas and biomethane, as the only alternative energy capable of providing ecological and immediate response to each and all of the transport needs in the city and also in the highway.
The emissions of NO2 or its precursor NO in Euro VI CNG vehicles are zero. In the case of solid particles, the emission of Euro VI NGVs is practically is near zero, with only 4% of the allowed limit. Light and medium CNG vehicles are by far the most economically and suitable available for urban transport in all categories of professional vehicles. This proven condition of NGVs with almost zero emissions offers municipal authorities the possibility of giving them a treatment proportional to their advantages, translated into greater mobility in restricted areas and lanes.
The CO2 emissions of a natural gas engine are about 15% lower than its diesel counterpart. With the evolution of CNG technology, it is certain that in the next generations of engines foreseen for 2017 and 2018 this difference will increase up to 20%. CNG is therefore the recommended urban fuel for all types of use. In the case of Madrid, the availability of biomethane produced in Valdemingómez offers great potential to significantly reduce the carbon footprint of urban transport.
The General Director of Sustainability and Environmental Control Paz Valiente commented on different aspects of the plans of the City Council for the improvement of air quality. On behalf of GASNAM, it does not only present the main document, but also made a series of considerations on the important emissions in urban area due to the diesel locomotives used in the containers terminals of the city and by the big cruisers and ferries in port cities.
