By Mark Scott and Jeremy van Loon June 4 (Bloomberg) — Los Angeles: city of freeways, smog, and — bike lanes? That’s where Mayor Antonio Villaraigosa wants to take his town. In one of the less likely transformations in the global effort to cut carbon output, Los Angeles plans to spend $230 million on 1,700 miles of bicycle paths, Bloomberg Businessweek reports in its June 7 issue. Most of the program will be completed by 2015, and includes changing rooms, showers, and bike storage areas operated by the city and private partners, the city’s Web site says. It comes on top of subsidies for installing solar panels and incentives for planting trees and switching to electric vehicles. “We have to make a change,” says Michelle Mowery, senior coordinator for the city’s bike program. “We can’t fit any more cars in.” From the freeways of Los Angeles to the canals of Amsterdam, cities are taking the lead in the fight to reduce carbon-dioxide emissions. As world leaders squabble over how to cut greenhouse gases, city hall is becoming the best hope for reducing heat-trapping emissions, Peter Lacy, a sustainability consultant at Accenture, said in an interview. Given their smaller jurisdictions, local officials can green-light eco-projects faster than national programs can be started. ‘Right Now’ “We’re not going to wait for national politicians, we’re acting right now,” Toronto Mayor David Miller said in an interview. His city plans to invest more than $1 billion in public transport and eco-friendly air-conditioning systems for buildings by 2017. The efforts could have a profound impact. Cities are home to more than half the world’s population and pump out more than two-thirds of CO2 globally. That may grow as people flock to megacities in the developing world, Angel Gurria , the secretary general of the Organization for Economic Cooperation and Development, said in Paris last month. “It’s obvious where the fight for a sustainable civilization will be decided, and that’s in large cities,” said Peter Loescher , chief executive officer of Siemens AG, which aims to profit from selling its streetcars, wind turbines, and other technologies to municipalities worldwide. Just as no two cities are alike, there are differences in local strategies. In Toyko, 68 percent of trips are already made by bike, subway, or on foot. Houston residents, by contrast, make 95 percent of their journeys by car. Markets vs Vehicles So while the Texas city is giving officials electric vehicles to reduce emissions, the Japanese capital in April announced a citywide CO2 cap-and-trade program, the kind the U.S. Senate has been unable to pass so far. Copenhagen will spend $1.6 billion by 2012 on bike paths, green energy projects, and retrofitting city buildings, said Frank Jensen, the city’s lord mayor. “We have a responsibility to our citizens to reduce emissions because so much carbon dioxide comes from cities,” he said in an interview. Melbourne plans to bar cars from downtown and offer incentives to developers who invest in efficiency. “It’s a green gold rush,” Melbourne Lord Mayor Robert Doyle said in an interview. London’s Effort London’s Mayor Boris Johnson is targeting a 400 percent increase in cycling over 2001 levels by 2026, according to the Transport for London website. The city’s government is opening designated cycling lanes across the capital it expects will add 120,000 cycle trips per day. The government is also making 6,000 bikes available for the public to rent from this summer. Johnson, who is also considering car-free days to fight pollution in the capital, rode with 65,000 cyclists across London last September. In Amsterdam, city elders are in the midst of a five-year, $1 billion program to improve creaking infrastructure. All of Amsterdam’s 2,400 houseboats have been fitted to use electricity instead of diesel. They’re now converting cargo barges as well. And some 300 homes are testing display panels that show energy usage in real-time, a program that may be expanded citywide. If residents can be convinced to take advantage of the technology to cut power use at peak times, their electricity bills could fall by up to 40 percent, said Ger Baron, senior project manager at the venture overseeing the project. “Our biggest challenge is changing people’s habits,” he said. Not to be outdone, New York has laid out a program called “PlaNYC.” The measures includes tax breaks for solar panels, legal changes that spur property owners to make buildings more energy-efficient, and power plants that use food waste and wood chips. Though a proposal to charge a congestion fee for drivers entering much of Manhattan was scrapped, New York officials aim to quadruple its 450 miles of bicycle paths by 2030. New York’s plan has even sparked envy on the West Coast. “Los Angeles isn’t New York,” said L.A. cycling chief Mowery. “But we’re getting there.” To contact the reporters on this story: Mark Scott in London at mscott50@bloomberg.net .
