CE envisions building individual facilities with a capacity of 2000 barrels per day, and deploying first projects in leading markets such as British Columbia and California where existing Low Carbon Fuel Standards favour fuels such as CE's which have ultra-low life - cycle carbon emissions.

The researchers day that Bicing saves around 12.46 lives per year in the Barcelona population, and that this positive result is corroborated by two different studies - a Dutch study that showed the benefits of cycling «substantially» outweigh the risks in the Netherlands, and a 2009 study published in the Lancet that showed very real public health benefits in the UK and India by reducing emissions and encouraging active transportation.

Natural gas delivered to market as LNG has life - cycle greenhouse gas emissions (ie extraction, pipelining, liquefaction, shipping, regasification, pipelining and burning for electricity) of roughly 600 - 800 kg of carbon per megawatt - hour of electricity.
