As a clean-burning, low-emission fuel, propane can serve a number of environmentally conscious fuel needs and enter into new markets that require similar levels of performance.

PERC’s emissions research provides life-cycle analysis of emissions of pollutants from propane-fueled systems. These studies respond to consumer demand for environmentally friendly fuels and equipment by quantifying propane emissions.

Carbon Management Information Center

Docket:16722

Propane is a low-carbon alternative fuel that produces significantly fewer greenhouse gas emissions than electricity and a number of other fuels. To ensure that propane benefits are understood and data is credible, the Gas Technology Institute formed the Carbon Management Information Center. The center is developing an online clearinghouse of propane-related research, conducting technology and market assessments of energy efficiency and emissions data, and providing technical input to voluntary and regulatory initiatives.

Forklift Emissions Data Literature Review

Docket:10853

In response to conflicting reports on emissions in the industrial truck industry, researchers conducted a comprehensive literature review of forklift emissions studies and a critique of the scientific merits of a variety of gaseous fuels, including propane. The results of this review were distributed to forklift trade magazines, with the purpose of better informing the forklift industry.

Fuel System and Composition Effects on Emissions Study

Docket:10951

The Environmental Protection Agency enacted federal emission standards for large, spark-ignited engines that power forklifts and other industrial equipment. In response to this legislation, researchers studied the effects of varying propane fuel compositions on forklift emissions and durability, the effects of sulfur on catalysts, and the effectiveness of fuel additives and filters.

Greenhouse Gas Emissions Study

Docket:15964, 12294

Propane produces significantly fewer greenhouse gas emissions than diesel and gasoline in a wide range of applications. Researchers quantified greenhouse gas emissions produced by propane in 13 selected applications using the GREET model. This research helps to communicate reliable information to stakeholders at the state and federal levels about the advantages of using propane technology.

Ozone-Forming Potential Assessment

Docket:16303

The Environmental Protection Agency introduced regulations to control emissions from combustion sources. In response, researchers conducted a literature review and tested a range of propane combustion processes to assess the relative ground-level atmospheric ozone impacts of propane emissions using the ozone reactivity values in the Maximum Incremental Reactivity scale.
