Low Gas Prices Tempt Consumers to Buy Gas Guzzlers, But They Should Resist

January 15, 2015 by Nick Nigro

The effect the sharp price decline in gasoline prices will ultimately have on greenhouse gas emissions is not yet known, but a reasonable estimate is that emissions will rise as less efficient cars and trucks become popular for the first time in years.[read more]

India Disdains a Global Approach to Mitigating Greenhouse Gas Emissions

December 9, 2014 by Henry Auer

India Mitigation Problems

By the time global warming drew worldwide attention in the last decades of the 20th century, developing countries were beginning intensive energy-dependent expansions of their economies, seeking to move from agrarian to industrialized societies. India and China are prime examples of this growth surge.[read more]

The European Union Continues on Its Course to Lower GHG Emissions

November 4, 2014 by Henry Auer

EU and GHG Emissions

The nations of the world are working toward establishing a new climate treaty by late 2015 that would lower future greenhouse gas emissions (among other provisions). Independently, the EU agreed to a significant goal in reducing emissions of greenhouse gases on October 23, 2014.[read more]

Record Greenhouse Gases Continue to Accumulate in the Atmosphere

September 24, 2014 by Henry Auer

Carbon Accumulation

The world’s climate is affected by the atmospheric accumulation of greenhouse gases (GHGs), which continued unabated over the course of 2013. GHGs in the atmosphere preferentially retain heat radiating from the earth’s surface and prevent its escape to space.[read more]

An Uptick in US Greenhouse Gas Emissions as Utilities Use More Coal

January 17, 2014 by Tom Schueneman

US Emissions Up

Finalizing its 2013 report on U.S. greenhouse gas emissions, the Energy Information Administration (EIA) projects an increase of 2 percent for the year, the first in three years. Over the longer term, U.S. greenhouse gas emissions have been in a downtrend, one that the EIA expects will continue.[read more]

Record Greenhouse Gases: Is 2 Degrees Still Possible?

November 15, 2013 by Tom Schueneman

Greenhouse Gases and Target Temps

The latest Greenhouse Gas Bulletin released last week by the World Meteorological Organization (WMO) revealed that global atmospheric greenhouse gases hit a new record high, rising 2.2 parts-per-million (ppm) from 2011 levels to an average 393.1 ppm in 2012.[read more]

Greenhouse Gas Emissions, Explained With Seven Balloons

August 1, 2013 by Lindsay Wilson

GHGs and Balloons!

These balloons may not actually look very threatening, but what they represent is large majority of positive climate forcings. Which, to state it in English means that these balloons (which technically shouldn't float so well) are major causes of climate change.[read more]

Neck and Neck: US and European Greenhouse Gas Emissions Trends

July 7, 2013 by Trevor Houser

US and European Emissions


The European Environmental Agency released their annual greenhouse gas inventory. Emissions in the European Union fell 3.3% in 2011 to their lowest level since the EEA began keeping track.[read more]

Climate Change Arithmetic: Missing the Big Picture

May 27, 2013 by Robert Wilson

Counting renewable energy, and not carbon is bad arithmetic. We keep our eye on the progress of renewables, yet the resurgence of coal in Europe gets ignored.[read more]


Carbon Bubble a Turning Point for Climate Change Action?

May 13, 2013 by Mitchell Beer

If the prospect of serious limits on greenhouse gas emissions translates into a real risk of stranded assets for fossil fuel companies, carbon may become the next housing bubble.[read more]

How Is Expanding Oil and Gas Production Consistent with Addressing Climate Change?

May 11, 2013 by Geoffrey Styles

An all-of-the-above approach to energy encompassing oil and gas, along with renewables, carbon sequestration, nuclear power and efficiency is fully consistent with addressing climate change.[read more]

Energy Efficiency or Dirty Digital Footprints? Looking at "Green" Websites' Energy Use

May 4, 2013 by Tom Schueneman

dirty data?


Most people think the web is a green medium, but the average website has a carbon footprint similar to a book or a newspaper. A 2011 analysis suggests IT is responsible for two to four percent of global greenhouse gas emissions.[read more]
