Cars, not livestock, greater contributors to greenhouse gas emissions

A recently published white paper sheds new light on the role of livestock production in greenhouse gas emissions.

Report: Pipeline climate impacts could double that of smokestacks

A new report by the Sierra Club finds that pollution from two proposed pipelines would almost double the total emissions from existing power plants in Virginia.


What’s the difference between a carbon tax and “cap-and-trade” system for reducing greenhouse gas emissions?

Most of us can agree that reducing greenhouse gas emissions is a must given the rapid warming of the planet; just how to do it best is another question entirely.

Today at an award ceremony honoring the Department of Motor Vehicles (DMV) energy efficiency efforts at the DMV Headquarters building in Richmond, Governor Terry McAuliffe signed Executive Order 31 to reduce energy consumption in state government.


Earth Talk: Ethanol’s unrealized promise

Ethanol and similar “biofuels” made from corn and other crops seem like a good idea given their potential for reducing our carbon outputs as well as our reliance on fossil fuels.


Earth Talk: Are fuel cell cars green?

Fuel cell cars have not caught on and skeptics wonder if they ever will. One big hurdle is that creating hydrogen fuel turns out to be highly inefficient compared to other readily available fuels.


EPA’s carbon pollution rules: Good for business, good for the economy

Some national business organizations have hammered the Environmental Protection Agency (EPA) for proposing new rules on carbon pollution from existing power plants, cutting carbon emissions by 30 percent by 2030, using 2005 levels as a baseline. What planet are they on?


Earth Talk: Preventing wildfires

There’s no question that wildfires are on the increase across the American West and other fire-prone regions of the world, and most environmental leaders agree that global warming is largely to blame.


EPA proposes new pollution guidelines for power plants

The EPA is releasing the Clean Power Plan proposal, which for the first time cuts carbon pollution from existing power plants, the single largest source of carbon pollution in the United States.


Earth Talk: Is organic agriculture sustainable?

Dr. Henry I. Miller, former director of the Office of Biotechnology at the U.S. Food & Drug Administration, argues that conventional farming—which uses synthetic pesticides, herbicides and fertilizers and often genetically modified (GM) seed stock to maximize yields—is actually better for the environment, producing more food and using less water compared to organic farming.


Study outlines plan for CO2 reduction from U.S. power sector

A new study by the American Council for an Energy-Efficient Economy (ACEEE) outlines how energy efficiency could be used in an upcoming standard by the U.S. Environmental Protection Agency to reduce CO2 levels with no net cost to the economy.


Earth Talk: Keurig K-Cup coffee containers

Keurig K-Cups—those little one-serving coffee containers that allow people to brew one cup at a time in a specially designed Keurig brewing machine—are all the rage these days.


Earth Talk: Cap and trade strategies to reduce carbon emissions

Cap and trade, whereby big polluters must pay to emit greenhouse gases against a capped total amount that is reduced over time—has been in effect across the European Union (EU) since 2005. This so-called Emissions Trading System (ETS) requires 11,000 of the largest electric and industrial facilities in 28 European countries to participate.

Earth Talk: Barack Obama’s climate change initiative

In what’s being billed as the greatest environmental initiative of his presidency, Barack Obama announced on June 25, 2013 that his administration is instituting stringent mandatory restrictions on greenhouse gas emissions by power plants, factories and other industrial sources. These sources combined account for roughly 40 percent of all greenhouse gas emissions across the U.S. The goal is to reduce overall greenhouse gas emissions nationally by four percent below 1990 levels within the next seven years.


Page Shields | Can coal be clean?

With all of the controversy surrounding the construction of a coal plant in Wise County, VA it bears repeating that coal is not clean energy. The phrase “clean coal technology” fosters hope that scientists will find a way to take harmful elements, especially carbon, out of coal. Unfortunately this is a lost hope as the […]


A clear direction on energy

We may not yet have a firm grasp on exactly what we need to do to merge the words clean and energy in perfect harmony, even with the 219-212 vote of the House of Representatives on cap-and-trade legislation last week. But we do at least have direction, and considering how much muck was thrown into […]
