EVs Reduce Greenhouse Gas Emissions, but They're Not Pollution-Free
To reduce harmful particulate matter emissions, we need fewer cars on the road—electric or otherwise, according to the findings of a recent report.
Social Equity: The Missing Leg of the Three-Legged Stool of Climate Action
Climate action plans cannot succeed without bona fide action on social equity and job creation, argues Murtaza Baxamusa who teaches planning at USC and develops affordable housing Murtaza Baxamusa.

China Plants 'Great Green Wall' of Trees
Net deforestation continues, but at a slower rate as the world's largest ecological engineering project stretches for a planned 2,800 miles. It is hoped the new trees will halt the advance of the Gobi Desert.
Op-Ed: Reintroduce California's Historic Restoration Tax Credit
Despite a veto by Governor Jerry Brown, California’s Assembly Speaker Toni Atkins should keep trying to pass legislation to encourage preservation, says Bay area preservation architect Jerri Holan.
Is Fracking Less Harmful Than Suspected?
How much methane, a powerful but short-lived greenhouse gas is released during fracking operations for natural gas? Until now, all studies, including those by the EPA, were done by estimates. This study went to over 500 well sites to measure leaks.
California Already Confronting ‘Significant’ Impacts of Climate Change
A new report by state scientists identifies three dozen environmental indicators that confirm the effects of climate change on California are ‘significant and growing.’
Where’s the Heat Going? Global Warming Lull Befuddles Scientists
Despite record levels of greenhouse gas emissions, global surface temperatures have risen at a much slower rate over the past 15 years than the 20 years prior. Scientists are struggling to explain a warming plateau.
The New Promise of Urban Ecology
Courtney Humphries takes a look at recent federal investment in research on the complex interrelationship between human settlements and the natural environment.
Why Some Electric Vehicles Are No More Green Than Gasoline-Powered Ones
Paul Stenquist analyzes the surprising influence that geography has on the carbon footprint of electric vehicles.
European Cyclist's Federation (ECF) Study on Reducing Greenhouse Gas Emmissions
In the fight against climate change, it is still unclear how, according to SustainableCitiesCollective, "the world’s nations will reduce greenhouse gas emissions and achieve limited temperature rise." A recent ECF study sheds light on the topic.
Encouraging Low Carbon Cities
Controlling carbon emissions hinges on encouraging cities that have small carbon footprints, writes Matthew E. Kahn.
Stopping Sprawl, Slowing Emissions, Improving the Economy
A new report suggests that making policies in Canada to avoid urban sprawl development will reduce pollution and boost the economy.
Transit, Not Traffic Reduction, Helps NYC Hit Greenhouse Gas Targets
Is New York City's green transportation revolution overhyped? It turns out that emissions from private cars actually increased between 2007 and 2009, and that almost none of the city's greenhouse gas reductions came from the transportation sector.
Artificial Trees Could Be Climate Key
Carbon dioxide is one of the most widespread greenhouse gases produced by humans. Trees can absorb it, but release it when they die. Scientists are looking to build artificial trees to do the job permanently.
Stockholm's Congestion Pricing Cuts Traffic, Boosts Clean Vehicle Sales
Stockholm's congestion charge is not only reducing traffic and greenhouse gas emissions, it's also increasing sales of alternative fuel vehicles.
Differences in City Greenhouse Gas Emissions
Different cities have different levels of greenhouse gas emissions. A new study looks at how they are different and why.
Oil Crunch Coming
Peak oil will happen at least 10 years earlier than most governments are expecting, and an oil crunch will occur in the next 5 years, says Dr Fatih Birol, chief economist at the International Energy Agency.
California Cities Object To Greenhouse Gas Law
California's SB 375 attempts to require cities to develop in a way that reduces greenhouse gas emissions. But some cities say the new law is misguided, and the state should focus on zero-emission vehicles instead.
Traveling beyond LOS (By foot? On a bike?)
Let me start with a disclaimer: I am not a transportation planner. At the points where transportation planning shares borders with engineering, I tend to zone out and start doodling in the margins. I do, however, have a lifelong interest in transportation, which is why I share the excitement of some of my more transportation-focused colleagues about potential changes in how California measures transportation impacts of projects.
Students Give Up Wheels for Their Own Two Feet
This piece from the New York Times looks at a program in Italy the encourages children to walk to school.
