Polyurethane is one of the world’s most widely used plastic materials, but it’s often overlooked in our daily lives. Yet whether you’re at home, at work or in your vehicle, it is usually not far away with common end-uses ranging from mattresses and
NASEM announces provisional committee for new study on life cycle analyses of low-carbon fuels
Low carbon fuel standards, such as the Federal Renewable Fuel Standard and the California Low Carbon Fuel Standard, are major US programs for reducing greenhouse gas (GHG) emissions from transportation fuels. These standards rely on life cycle assessment (LCA) as a tool to estimate fuel GHG emissions.
However, current LCAs differ notably in how they are implemented, with disagreements pertaining to data quality, modeling approaches, and key assumptions.
The ad hoc NASEM committee will assess current methods for estimating lifecycle greenhouse gas (GHG) emissions associated with transportation fuels (liquid and non-liquid) for potential use in a national low-carbon fuels program. In carrying out its assessment, the committee will identify the general characteristics and capabilities of GHG emissions estimation methods that would be commonly needed across various types of low-carbon fue
