The carbon footprint of LPG is 50% lower than coal.
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 minimizing GHG emissions.
In the US, using LPG rather than electricity for space heating can reduce CO2 emissions by up to 54%.
Driving on Autogas leads to a reduction of 10-12% in CO2 emissions as compared to petrol
LPG’s contribution to mitigating emission is-two fold:
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’s advantage over electricity is even bigger: 30% lower GHG emissions in South America, 35% lower in Japan, 38% lower in the Republic of Korea and up to 54% lower in North America.
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 cook tops, 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.
Regardless of the application, switching to LPG will help reduce CO2 emissions.
Black carbon or BC, microscopic airborne particles 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.
As global decision makers continue to debate the effects of climate change and seek ways to reduce GHG emissions, LPG can offer significant near-term solutions. LPG is not only among the most attractive options for reducing GHG emissions, but it is abundantly available today in many parts of the world through existing distribution channels. Switching to LPG can help to immediately reduce GHG emissions in many applications and parts of the world. LPG also can be easily delivered to developing regions which may not have existing natural gas or electricity distribution infrastructures, offering an immediate, cost-effective, and low-carbon energy solution. When combined with other environmental, cost, and performance advantages, it is clear that LPG is an ideal clean energy for a low-carbon world.
Climate policy must be broadened to include black carbon emissions. Doing so will take advantage of already existing technologies such as LPG that have known low black carbon emissions profiles and will mitigate dangerous climate change more quickly than reductions in CO2 and other greenhouse gases.
