Emissions & Climate
As a low-carbon, low-polluting fuel, LPG is recognised by governments around the world for the contribution it can make towards improved indoor and outdoor air quality and reduced greenhouse gas emissions. In many applications and regions LPG is among the most attractive energy options for minimising GHG emissions.
LPG’s contribution to mitigating emission is twofold:
Reduced CO2 Emissions
Whether used for cooking, transport, heating or industrial applications, LPG is a clean-burning fuel that will reduce CO2 emissions compared to biomass, fuel oil and, in many countries, electricity.
When heating a home, LPG helps consumers significantly reduce their carbon footprints. In Europe, LPG offers 15% lower GHG emissions than heating by fuel oil.
LPG is also among the lowest carbon-emitting fuel sources for cooking in many regions of the world. In India, for example, LPG emits 60% fewer GHGs than electric coil cooktops, 50% fewer emissions than some biomass stoves, and 19% fewer GHGs than kerosene stoves.
When used as a transport fuel, LPG emits less CO2 than other hydrocarbon fuels when in combustion. Driving on Autogas leads to a reduction of 10-12% in CO2 emissions has been calculated in a petrol-powered car in an identical engine.
LPG and black carbon
Black carbon or BC, microscopic airborne particles are commonly known as soot, which some experts rank as the second biggest contributor to climate change after carbon dioxide (CO2).
Black carbon is emitted from incomplete combustion in diesel engines, industrial smokestacks, residential cooking fires and heating stoves among other things. But because black carbon stays in the atmosphere for only days or weeks, moving quickly to expand access to already existing clean technology can be an effective rapid response to reducing black carbon emissions.
Black carbon warms the planet by absorbing heat in the atmosphere and by reducing albedo, the ability to reflect sunlight when deposited on snow and ice. Black carbon stays in the atmosphere for only several days to weeks, whereas CO2 has an atmospheric lifetime of more than 100 years. Thus, reducing black carbon will deliver immediate cooling more quickly than reductions in CO2 and buy time to keep temperature increases below a critical value while long term strategies for reducing CO2 emissions are implemented.
LPG emits virtually no particulates and witching to LPG can thus have an immediate impact on global warming.
BioLPG is a 100% renewable fuel as it is made from a mix of wastes and residues, and sustainably sourced vegetable oils. It is chemically indistinct from LPG but has the same physiochemical properties and can therefore be delivered, stored and used in exactly the same way as LPG is. BioLPG can further reduce emissions by up to 90%
Autogas (LPG as a vehicle fuel) is the most accessible alternative vehicle fuel. Driving an LPG vehicle is safe, easy and, in many countries, considerably cheaper than driving a petrol or diesel model. LPG also emits less CO2 and far less other emissions such as NOx.
