Carbon Trading with Chinese Characteristics
To control greenhouse gases the Chinese government is experimenting with pilot programs in seven cities and regions that use markets By Mark Nicholls NEW CITY: On June 18, companies in Shenzhen will have to meet greenhouse gas emission targets as part of a new cap and trade market experiment. Showcasing more than fifty of the most provocative, original, and significant online essays from 2011, The Best Science Writing Online 2012 will change the way… On June 18 China’s pioneering city of Shenzhen is set to notch up another first. From that day 635 companies in the Shenzhen Special Economic Zone—which in 1979 became the vanguard for China’s capitalist revolution—will start using the markets to help meet greenhouse gas emissions targets . This year, alongside the cities of Beijing, Shanghai, Tianjin and Chongqing as well as the regions of Guangdong and Hubei, Shenzhen is imposing greenhouse gas targets on hundreds of companies, ranging from power plants to airport operators. The goal is to develop a national carbon market over the next decade that could help put the brakes on the world’s largest carbon dioxide emitter. “China has internationally pledged 2020 climate targets,” observes Chai Hongliang, an analyst at Thomson Reuters Point Carbon, an Oslo-based information-provider specializing in carbon markets. He is referring to a commitment first made by China ahead of the 2009 Copenhagen climate talks to reduce its economy’s overall carbon emissions per unit of GDP to 40 to 45 percent below 2005 levels by 2020. “It has two ways to reach the target: shut down factories in the last months of 2020 or use more market-based approaches like emissions trading,” Chai adds. As with emission-trading programs elsewhere, polluters in China’s pilots have two options: First, they can meet their targets by reducing their own emissions—by investing in energy efficiency, say, or curbing production. Alternatively, they can buy carbon allowances or credits from companies that have spare allowances or from projects elsewhere in China. Shenzhen faces the toughest target. The companies in its pilot emitted the equivalent of 31 million metric tons (Mt) of CO2 in 2010. They will be allocated around 100 Mt of allowances for the duration of the three-year trial, although expected economic growth means they will have to reduce their carbon intensity by an estimated 30 percent by 2015 compared with 2010. Balancing the need for economic growth with carbon control is a challenge. Emissions in China are expected to rise for years, given the importance China’s political elite continue to place on economic growth. Some observers question how much pressure China’s planners are prepared to put on its big emitters. The pilots set emission limits from January 2013 through the end of 2015. “I think the emissions caps will be relatively lenient,” Chai says. Certainly the regulators will be eager to avoid any “carbon leakage”—that is, driving industry out of their jurisdictions through imposing too stringent targets ahead of any national program. But at this point Chai can only speculate about their stringency. Limited information is available about participating companies, their historical emissions—and even the rules under which the pilots will operate. And part of the reason is that some of these data do not exist. The problem with data To run effectively markets rely on an unimpeded flow of information, clear rules and rigorous oversight. China could both benefit from the lessons of earlier efforts, such as Europe’s flagship carbon market—the world’s largest, known as the European Union Emissions Trading System, or ETS. It is under fire from some environmentalists because of its relatively lax targets and low carbon prices, along with its vulnerability to fraud and abuse. For the regulators drawing up targets, “there are existing processes and mechanisms on energy consumption which could be drawn on, as well as local exercises in creating GHG [greenhouse gas] inventories,” says Lina Li, a Beijing-based carbon markets expert at Netherlands-based consultancy Ecofys. Her firm has advised local regulators and international donors on creating carbon market regulations and infrastructure in China. “But there are still challenges regarding emissions data at the company level.” This is exactly where the E.U. was in 2005, when it embarked on the pilot phase of its ETS—and the lack of emissions data allowed companies to game the system. E.U. governments asked companies to provide their own, unverified historical emissions data, and many inflated their numbers so as to claim more free allowances from government. This practice created an overhang of surplus permits that led to a price collapse in 2007. Generous allocations of allowances are probably inevitable as the price paid for industry acceptance, however, suggests Karl Upston-Hooper, legal counsel of GreenStream Network, a Finnish carbon asset manager that is active in China. “You will struggle to find an ETS that is not overallocated” in its early phases, he says. Indeed, he argues that the pilots in China are less about creating carbon markets and more about gathering data. “I’ve taken the view that they’re implementing an emissions-monitoring system, not a carbon market—and I’m okay with that as a first step on the road.” Most observers—including from the environmental movement—are prepared to give China’s regulators time to get things right. “It is our view that the first step for Chinese ETS is to get the system right from the beginning—the trading platform; the monitoring, reporting and verification system; [emissions] inventories; getting companies informed and cooperative—and gradually shift toward more stringent caps,” says Li Shuo, a climate and energy campaigner for Greenpeace East Asia. Plenty of studies see China’s emissions peaking by 2030. Some are more optimistic: recent ones predict 2025 to 2030. A further data challenge is whether China’s regulators will be sufficiently transparent and even-handed when it comes to the country’s carbon markets. “In Europe and elsewhere, ETS data are under public scrutiny. That may not be the case in China,” says Point Carbon’s Chai. Another concern is insufficient coordination among the seven pilots, Li says. Indeed, rivalry exists among the various authorities, with Beijing deliberately encouraging a degree of “policy competition” to test differing approaches to see which works best. Last, despite a recent announcement by the powerful National Development and Reform and Commission (NDRC) that it is to propose a national carbon cap for China’s next five-year plan, which runs from 2016 to 2020, a national Chinese carbon market is not assured. Other methods could prove more effective. “In China the ETS is not the only tool,” says Wu Changhua, Beijing-based Greater China director of the nonprofit Climate Group. She notes that the nation’s finance ministry is promoting a carbon tax whereas other government ministries are considering a system for crediting and trading energy-efficiency improvements. Wu also cautions that international media speculation around the introduction of a national carbon cap by 2016 is overblown. She argues that the NDRC is agitating for the inclusion of the concept in the next plan to ensure resources are available for more research and policy development. “One thing is for sure,” she adds. “The political leadership in China is much more serious, stronger and determined to tackle environmental problems. But it will be a journey. We’re not going to get there immediately.” Continue reading
Biofuels Will Play Integral Role In California’s Energy Future, Says New EBI Study
Biofuels developed from plant biomass and purpose-grown crops can substantially move California toward its ambitious energy goals, a new report says, but only through the wise allocation of feedstocks and the success of energy efficiency measures throughout the state. That’s the conclusion of “California Energy Future: the Potential for Biofuels,” a report of the California Council on Science and Technology (CCST) co-authored by Energy Biosciences Institute scientists Heather Youngs and Chris Somerville. The study is one of seven produced by the CCST’s California’s Energy Future Committee, which was tasked with understanding how the state can meet aggressive reductions in greenhouse gas (GHG) emissions required by California policy by 2050. The biofuels paper, according to lead author Youngs, a Senior Fellow at the EBI, addressed six scenarios of varied supply and demand options. They illustrate that the degree to which biofuels may help California meet its emissions goals depends upon how future demand for fuels rises or falls and what technologies are developed. Other factors include energy crop availability, investment decisions, public acceptance, and competing demands for renewable energy resources. “The concerns regarding large-scale use of biomass for energy in California are largely a matter of sustainable resource management,” Youngs said. “Judicious use of feedstocks will be required to obviate long-term sustainability concerns and maximize efficient resource management.” The researchers concluded that next-generation biofuels can reduce greenhouse gas emissions of transportation to meet the target GHG reduction goals of the state, but deep replacement of fossil fuels through implementation of low-carbon lignocellulosic ethanol and advanced biomass-derived hydrocarbons (drop-in fuels), and reduction in demand, are required. The challenge for California lies in landmark State Executive Order S-03-05, signed by Arnold Schwarzenegger in 2005. The target: reduce greenhouse gases (GHGs) more than 80 percent from 1990 levels by 2050. The California Legislature has also enacted legislation to encourage low-carbon technologies. Assembly Bill 32, The Global Warming Solutions Act of 2006, put a 2020 GHG target officially on the books. It also paved the way for the Renewable Portfolio Standard that requires 33 percent renewable electricity by 2020, and for adoption of California’s landmark 2009 Low Carbon Fuel Standard. The CCST’s first report in its California Energy Future series summarized the conclusions of a two-year study — in order to reach those goals, a little bit of everything will be required. This includes increased efficiency through reduced demand, shifts to electrification, decarbonized electricity production, and decarbonized liquid and gaseous fuels. Subsequent reports reveal the details, delving into nuclear power, transportation and building efficiency, electricity from renewable sources, and advanced technologies. One key finding of the Committee was that low-carbon fuels are absolutely required to reach the GHG reduction goals. Even with electrification of some vehicles, liquid fuels will still be required for aviation, marine and heavy-duty transportation. “Substantial amounts of low-carbon biofuels would be required even with optimistic efficiency, electrification, and implementation of other renewable energy sources,” the authors state. California has a policy goal of producing 75 percent of its biofuels from in-state resources. Biofuels can be produced using agricultural wastes, forest thinnings and harvest residues, municipal wastes, and purpose-grown energy crops such as perennial grasses and short rotation woody crops. According to the report, this could be difficult. The state could produce 40-120 million tons of biomass or 3 to 10 billion gallons of fuel each year, meeting up to 60 percent of the 2050 demand in the most optimistic case. Success will depend upon overcoming a number of economic, social and sustainability barriers, Youngs said. “Biofuels could reasonably be imported from other states or countries like Brazil,” she noted. “While imported biomass could supply in-state biorefineries to meet the 75 percent goal, this solution would be more costly than the import of biofuels themselves to meet the GHG reduction goals. Decisions regarding biomass use and biofuel import will greatly affect the ability of the state to meet its policy goals.” The authors expressed confidence that future technologies could be deployed to produce a new generation of low-carbon biofuels, like cellulosic ethanol and drop-in biofuels, to meet the demand by 2050. They also urged the proper choice of species and production criteria for feedstocks and fuel conversion technologies by region in the state. This includes development of arid-tolerant feedstocks, water-minimizing conversion technologies, use of grasses that sequester soil carbon and recycle nutrients, and use of plants that can tolerate poor soils and do not compete with food or feed production. All of these issues are being studied at the EBI in Berkeley and Illinois. Source: University of California – Berkeley Continue reading
Biofuel Development Key To Meet California’s GHG Emission Reduction Goal
11 Jun 2013 Biofuel development could be the answer for California to meet its 2050 greenhouse gas emission reduction goal, according to a new report that focuses on the state’s biofuel potential. The report titled “California Energy Future: The Potential for Biofuels,” done by the California Council on Science and Technology, co-authored by Heather Youngs and Chris Somerville, concluded that developing the potential for next-generation biofuels can help reduce greenhouse gas emissions, specifically, replacing the use of gasoline with cellulosic ethanol and biodieasel. However, replacing gasoline with conventional cellulosic ethanol and biodiesel can only reduce California’s emissions by as much as 53 percent of the 80 percent GHG emissions reduction goal. In order for the state to meet its target, the report suggested developing other alternatives to fossil fuel such as low-carbon lignoecellulosic ethanol or biomass derived from hydrocarbons and a reduction in the overall demand for fuel. The authors of the report cautioned that even with optimistic efficiency, electrification, the use of other renewable energy sources, the use of extensive amounts of low-carbon biofuels is still needed. That is why when it comes to the issue of using vast amounts of biomass to power the state; the authors explained that “sustainable resource management” and “judicious use of feedstocks” is needed to fully maximize the resource. Currently, California is targeting 75 percent of its biofuels from its state resources. According to Ms. Youngs, reaching the 75 percent goal can be met by importing biomass from countries like Brazil, of which will then be used to supply the state’s biorefineries, however, this would prove very costly. The target of reducing GHG emissions by 80 percent from 1990 levels by 2050 comes from the State Executive Order S-03-05 that was signed by then governor Arnold Schwarzenegger back in 2005. With such a timeframe, Ms. Youngs believes that technologies can be deployed to produce low carbon biofuels by then, but this deployment of technologies will still have to depend on factors such as biomass supply and economic considerations. In another report also done by the California Council on Science and Technology, titled “California’s Energy Future – The View to 2050,” it was found that i to make a mark on the 2050 GHG emissions goal would require different strategies. The strategies in the report were stringent efficiency measures; avoiding the use of fossil fuel through electrification; doubling the use of electricity produced from renewable energy and other sources as well as storing carbon dioxide emissions underground; and getting enough supply of low-carbon fuel. – EcoSeed Staff Continue reading
