How Zoning Affects Greenhouse Gas Emissions
As the urgency of the climate crisis increases, a paper in the Notre Dame Law Review argues that increased density is not a universally effective strategy to reduce emissions and that different strategies are needed for low-carbon places versus high-carbon ones.
Largest Carbon Capture Plant in the World Opens in Iceland
The plant draws carbon from the atmosphere and turns it to stone in underground wells, but the technology remains relatively expensive.
Keeping An Open Mind: How Some Cities Are Reducing Emissions While Supporting Economic Vitality
As cities swell and car use soars, U.S. cities should take note of some bold, even radical, emissions-reducing policies being deployed around Europe.
Global Reverberations from EPA Rollback of Fuel Economy Standards
Relaxed U.S. fuel economy standards, as Environmental Protection Administration chief Scott Pruitt announced on April 2, would have effects extending far beyond the United States.
Climate Change Lesson Number One from the California Fires
Whether climate change 'caused' the California fires is a red herring, argues disaster resiliency expert Dave Hampton, in this first part in a series on lessons from the California fires about climate change.
Will the Historic Climate Accord Survive the U.S. Political Process?
While environmentalists were hailing the historic carbon emissions reduction agreement between the leaders of the United States and China, the world's two largest emitters, Republican leaders wasted no time in slamming the accord.
Breaking News: China and U.S. Agree to Emissions Reduction Plan
A surprise, groundbreaking agreement between China and the United States was unveiled in Beijing at the end of the APEC conference, providing hope that the world can reduce the threat from climate change.
Is the World Approaching "Peak Emissions"?
A new report published by the Netherlands Environment Assessment Agency and the European Commission's Joint Research Centre sees the slowing growth of global CO2 emissions as an indication that we may be headed towards an eventual emissions decline.
A Silver Bullet for Climate Change?
Even as the world (unsuccessfully) tries to formulate a treaty to get nations to reduce their carbon emissions, researchers indicate it may be too late - the tipping point may have been reached. But what if CO2 could be extracted from the air?
The Surprising Environmental Benefits of Size and Density
A recent article from Richard Florida shows that the size and density of cities offers considerable advantages to the environment, beyond what is commonly understood.
Capturing Carbon in Rocks Gains Traction
Michael Coren explores a potentially solid idea for carbon sequestration - turning our greenhouse gas emissions into underground rock formations.
Huge Jump In CO2 Emissions Reported For 2010
As delegates from 191 nations gather in Durban, South Africa to tackle climate change, a new report shows the largest increase in carbon emissions, and the greatest percentage increase since 2003. Coal combustion accounts for more than half the gain.
Bamboo, the Miracle Homebuilding Material
Bamboo homes survive earthquakes and typhoons, it grows like a weed, and has twice the compression strength of concrete. Elisabeth Best reports on the wonder material and the image problem bamboo must overcome to be used more widely.
50mph Speed Limit Would Cut CO2 By 30%, Says New Study
Reducing the speed limit to 50 mph, say researchers, would create the tipping point where taking transit or modes other than driving will become more attractive and therefore save CO2 emissions.
Household CO2 Emissions Worse in Suburbs
New maps created by the Center for Neighborhood Technology show that while emissions are greater per acre in cities, they are greater per household in suburbs.
