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.

Even though the United States withdrew itself from the landmark Paris Agreement, countries around the world are still committed to cut their carbon emissions in accordance with their respective INDCs (Intended Nationally Determined Contributions) in the UNFCCC framework. Nonetheless, experts say there exists a ‘gap’ between the collective outcome of these efforts and what is required to achieve the so-called 2-degree goal. How do they figure out the existence and the width of such a gap? There is a special tool to quantify and simulate the effects of various policies on the emissions.

- 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.

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 . About two-thirds of the produced electricity comes from fossil fuel combustion, mostly coal and natural gas . 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.

- Date of publication: February 2005
- Authors: Peter J. Robinson

Artists will probably find beauty in a piece of Dutch landscape paintings in the 17th Century, but climate scientist may see it as a data set; art work can be important evidence of the Little Ice Age that lasted from 1300 to 1850 . An interesting study titled “Ice and snow in paintings of Little Ice Age winters” examines how artists in Europe depicted the colder weather and how we can get information about climate from those paintings.

- Title: Reconciled climate response estimates from climate models and the energy budget of Earth
- Date: June 2016
- Authors: Richardson et al.
- Published by: Nature Climate Change
Naturally, there are always some gaps between the real world and the results from simulation models. In case of climate sensitivity, which refers to the temperature increase from doubling CO2, the real-world data that has been historically recorded gives us around 1.3 , while models gives us a little bit higher value. Climate skeptics often use this fact to support their argument; that global warming is not in fact that serious as scientists predict. However, a study published by Nature Climate Change this last June, Reconciled climate response estimates from climate models and the energy budget of Earth (Richardson et al., 2016), addresses why climate sensitivity is predicted differently from climate models and observed data.

Reducing the national emissions often involves a powerful policy tool such as carbon tax or emission trading. While many focus on the effectiveness of such measures in cutting carbon emissions, there have been some serious discussions on how to spend the money gained from tax or cap-and-trade auctions. We are talking about some BIG money here; for example, California is reaping over $2 million annually from its cap and trade, and the proceeds are expected to grow over time .
