The Fallout from Volkswagen's "Defeat Device"

September 24, 2015 by Geoffrey Styles

I find the revelations concerning Volkswagen's reported efforts to circumvent vehicle emissions rules disturbing, especially as a VW owner and someone who has advocated diesel technology as a tool for reducing oil consumption and greenhouse gas emissions.[read more]

Will the Clean Power Plan Deliver Effective Emission Reductions?

August 10, 2015 by David Hone

Clean Power Plan

August 3rd saw the Obama Administration release its long awaited Clean Power Plan. The plan partly underpins the current US COP21 INDC (Intended Nationally Determined Contribution) to reduce emissions by 26-28% by 2025 compared to 2005.[read more]

Monthly Power Sector Carbon Dioxide Emissions Reach 27-Year Low in April

August 5, 2015 by U.S. EIA: Today in Energy

Monthly Emissions

The electric power sector emitted 128 million metric tons of carbon dioxide (MMmt CO2) in April of this year, the lowest for any month since April 1988, according to the most recent estimates in the Energy Information Administration's Monthly Energy Review.[read more]

Does Europe Really Need an EPS to Keep from Falling Behind America?

December 9, 2014 by Sieren Ernst

Last month at the European Parliament, the WWF held an event that was titled: “Fighting Coal CO2 Pollution: Is the EU Falling behind the US?” It was held to discuss the US use of an Emission Performance Standard (EPS) as a part of the climate change regulations that it will be effecting under the Clean Air Act.[read more]

Colder Weather Drives Forecast of 2014 Energy-Related CO2 Emissions 1.1% Above 2013 Level

November 2, 2014 by U.S. EIA: Today in Energy

Weather and Emissions

Energy-related carbon dioxide emissions are driven by economic and efficiency trends and changes in the fuel mix. But weather fluctuations, which drive the level of energy use for both heating and cooling, are a significant factor affecting year-to-year variation in fossil fuel consumption and their resulting emissions.[read more]

Lower Electricity-Related CO2 Emissions Reflect Lower Carbon Intensity and Electricity Use

October 24, 2014 by U.S. EIA: Today in Energy

Carbon Intensity and Energy Use

U.S. energy-related carbon dioxide emissions have declined in five of the past eight years. This trend has been led by emissions reductions in the electric power sector. Electricity demand growth has been lower than in the past and at the same time the power sector has become less carbon intensive.[read more]

U.S. Fuel Economy Hit New Highs With 2013 Models

October 13, 2014 by Christina Nunez

Fuel Economy Records

American cars are using less gas per mile and emitting less carbon dioxide than ever before, according to a government analysis released Wednesday. The average fuel economy of 2013 models is 27.6 miles per gallon for cars and 19.8 miles per gallon for trucks, both of which are all-time highs.[read more]

Explaining Carbon Capture and Storage

October 6, 2014 by David Hone

Carbon Capture and Storage

Few of us have the time to really think about an issue such as climate change, let alone read books on the subject or attend seminars, lectures and climate conferences, although quite a few of these don’t mention CCS at all and some barely acknowledge the need for a carbon price.[read more]

Latest EIA Report Shows Marked Increase in U.S. CO2 Emissions

September 30, 2014 by Tom Schueneman

U.S. Emissions Growth

As the World Meteorological Organization recently reported, atmospheric CO2 concentrations have risen to record levels. In line with this report is the latest Monthly Energy Review from the U.S. Energy Information Administration finding that U.S. CO2 emissions have reversed their downward trend.[read more]


A Path to Carbon-Free Ammonia?

August 14, 2014 by N Nadir

Ammonia and Carbon

The synthesis of the agricultural and chemical commodity ammonia, which is of critical importance to humanity, is currently inextricably involved with fossil fuels. This post discusses a publication in the primary scientific literature that suggests a path to decoupling ammonia synthesis from the industrial use of carbon.[read more]

No False Choices: To Preserve A Livable Climate, We Need To Slash Both CO2 And Methane

July 12, 2014 by Joseph Romm

Cutting Emissions

The bad news is that humanity has dawdled for so long that our only realistic chance to avoid multiple, irreversible, catastrophic climate impacts is to slash both carbon dioxide and the “super pollutants” like methane sharply starting as soon as possible.[read more]

Five Chinas & the Cartoon Guide to Climate Change

June 25, 2014 by David Kroodsma

Growth and Carbon Emissions


In the past six weeks, Lindsey and I have biked across Turkey, talking to people about climate change. While a summary of our impressions can be found in this blog post, what struck us the most is how much new infrastructure, and especially power plants, Turkey is building.[read more]

Obama's New Carbon Rules: What Price Regulation?

June 12, 2014 by Bill Chameides

Carbon and Price Regulation

Can good economic times roll while carbon emissions decline? Maybe so. In a three year span, from 2010 to 2012, United States CO2 emissions declined while both the gross domestic product and the number of jobs on the United States rose.[read more]

Hoping for a Rational Climate Change Discussion

May 22, 2014 by Robert Rapier

Climate Change and Public Discourse

I suppose the topic of climate change will always be polarizing. One side believes that fossil fuel consumption threatens our very existence while the other sees climate change as a huge scam. There are many shades of gray between these extremes, but the most extremist views are generally the loudest voices.[read more]

Friday Energy Facts: Projected CO2 Emissions Vary with Coal and Nuclear Plant Retirements

May 2, 2014 by U.S. EIA: Today in Energy

Emissions and Retirements

Significant retirements of nuclear and coal power plants in the United States could change the amount of CO2 emitted by the electric power sector. EIA's Annual Energy Outlook 2014 features several accelerated retirements cases that represent conditions leading to additional retirements.[read more]
