NREL Project: Life Cycle Assessment Harmonization

As discussed in a previous post,  the respective contribution of each electricity generation technology to total greenhouse gas emissions is sometimes analyzed by lifecycle assessment. Currently, U. S. National Renewable Energy Laboratory (NREL) is conducting a research project on this particular topic in order to reduce uncertainty around estimates for environmental impacts and to increase the value of these assessments to the policymaking and research communities.

[Summary]Measuring the progress and impacts of decarbonising British electricity

  • Title:  Measuring the progress and impacts of decarbonising British electricity
  • Date: December 2016
  • Author: Staffell, I.
  • Published: Energy Policy

Most advanced economies around the world are striving to cut its greenhouse gas emissions through a diversity of policies. But how could one measure the progress? This paper gives a good example of examining which data sources to look into, how to calculate carbon emissions from different sources, and what uncertainties are.

Associating GHG Emissions with Electricity Generation

It is elementary: a large part of greenhouse gas emissions are attributable to power generation, especially to fossil fuel combustion. According to the Environmental Protection Agency (EPA), electricity production accounted for 30 percent of the U. S.’s total GHG emissions in 2014, marking the largest share [1]. About two-thirds of the produced electricity comes from fossil fuel combustion, mostly coal and natural gas [2]. It can be implied that employing less carbon-intensive technologies such as renewables and nuclear—although the latter can be politically charged—would lead to less GHG emissions.
