In January 2012, for the first time, the U.S. Environmental Protection Agency (EPA) released greenhouse gas (GHG) data collected under the GHG Reporting Program. GHG is primarily Carbon Dioxide but includes many other other chemicals such as methane. …

An effort to decrease emissions of the super greenhouse gas HFC-23 has led to a largely-false carbon market that should be eliminated, argues the Environmental Investigation Agency (EIA). HFC-23 is a byproduct of the refrigerant HCFC-22, which is curre…

Fast-growing exports of coal from rich countries to China show the limits of domestic greenhouse-gas policy.

A study estimates that the 10 states in the regional initiative will realize $1.6 billion from a three-year period in which the cap-and-trade market operated.

Green house gases are such materials as Carbon Dioxide and Methane that are implicated in global warming. From a permitting point of view it is a new phenomena. Today, the U.S. Environmental Protection Agency (EPA) issued the first Texas Greenhouse G…

Green house gas emissions such as carbon dioxide have been increasing. NOAA’s updated Annual Greenhouse Gas Index, which measures the direct climate influence of many greenhouse gases such as carbon dioxide and methane, shows a continued steady upwa…

Hydroelectric power is often promoted as green energy, yet dams, especially in the tropics, can be significant sources of greenhouse gas emissions. When built, reservoirs trap vegetation, which, as it rots, emits both methane and carbon into the atmosp…

Ahead of the latest round of climate change talks to be held in Durban, South Africa later this year, most countries, with the exception of European Union member states, Australia, and few others, have failed to advance national initiatives to regulate…

A new analysis supports other work showing a big climate benefit from choosing gas over coal for electricity generation.

In a report with wide-reaching political implications, U.S. EPA’s inspector general has found that the scientific assessment …
