Ranking carbon emissions of urban transport modes

The chart above shows the relative greenhouse gas emissions for various transportation vehicles. TNMT, a data analysis group of the Lufthansa Innovation Hub aggregates data for the chart with the caveat that the numbers are not exact (for example, cars vary greatly in their gasoline consumption, but an average can be approximated). Emissions are often not obvious; for instance, a vehicle may have low emissions while driven, but the manufacturing of it may produce a lot. The chart is useful for making individual decisions as to vehicle choices or frequency of vehicle use. It shows that we can make big reductions in our carbon footprints if we are deliberate in our use of travel technologies. If we choose to use one for short errands and another for long-distance travel, that will be significantly beneficial. — Steve Price

A new report from California Walks and the University of California Safe Transportation and Education Center (SafeTREC) highlights strategies to promote safer streets in El Cerrito and Richmond Annex, especially for slowing down traffic and making pedestrian- and bike-friendly improvements on San Pablo Avenue, Central Avenue, Carlson Avenue, and Cutting Boulevard. “ El Cerrito and Richmond Annex Summary and Recommendations Report ” is the culmination of a workshop convened on July 25 by the Community Pedestrian and Bicycle Safety Program (CPBST), a project of California Walks and SafeTREC.

OUT IN THE WORLD WITHOUT A CAR: The Spring Ride

Image
By Laura Lent Since 2002 I have been part of an informal group of friends who go on an annual bike tour we call the "Spring Ride."  We've bike camped our way from the Antioch BART station to Yosemite and various Sierra foothill destinations, we've gone north and south along the coast, and we've taken AMTRAK to Bakersfield and ridden north through Carrizo Plain. We've stayed at a dozen different campgrounds in the "reservoir belt" of the Sierra foothills.   Laura Lent at this year’s Spring Ride. Photo: Joel Pomerantz We generally carry our own gear in panniers, but are often joined by and sometimes partially sagged (support provided and gear carried) by friends in vehicles. A core group rides the entire time, while others join as they can.  While we delight in searching out bucolic backroads, canalside trails, and creative shortcuts, it's always necessary to ride on some busy roads as well. The Spring Ride is not about getting there quickly, but a

HURRAH FOR USABLE BIKE RACKS! El Cerrito Natural Foods

Image
What is an essential destination for daily living, a place that sustains basic metabolic life? A grocery store! How should you get there if you can't afford a car? You should be able to walk, take a bus, or ride a bicycle. El Cerrito Natural Grocery Company is accessible by all three modes. It is a short walk for nearby residents of El Cerrito and the Richmond Annex—from El Cerrito, crosswalks on San Pablo Avenue deliver you to its front door; it is also on one of the busiest bus routes in the Bay Area—AC Transit’s 72 bus; and it welcomes bicycle riders with visible bicycle racks right near its front entrance. Its inverted-U racks make it easy to lean and lock a bike without the bicycle tipping over. El Cerrito Natural Grocery Company is a role model for providing access to an essential destination for everyone, even if you're car-free. Good bicycle racks help make it so. Wouldn't it be great if every business was this accessible?!
