China, U.S. agree limits on emissions, but experts see little new | Reuters

China and the United States agreed on Wednesday to new limits on carbon emissions starting in 2025, but the pledge by the world’s two biggest polluters appears to be more politically significant than substantive.

As China’s President Xi Jinping agreed to a date for peak CO2 emissions for the first time and also promised to raise the share of zero-carbon energy to 20 percent of the country’s total, President Barack Obama said the United States would cut its own emissions by more than a quarter by 2025.

For APEC, Beijing Briefly Cleans Up Its Skies, but Can’t Help the Sewage – Businessweek

Beijing has, once again, cleaned up the air to impress the foreign dignitaries visiting for this week’s APEC summit. The phenomenon is so predictable that there’s even a new phrase on Chinese social media, “APEC blue,” used to refer to something that is beautiful or enticing, but also fleeting. As in, “He’s not that into you, it’s just APEC blue.”

Yet while China’s government can order factories in and near Beijing to shut down for about a week to clear the skies, it can’t as quickly clean up the capital’s dirty urban waterways. A new investigation by the newspaper Economic Information highlights one nasty but lingering problem in Beijing and other large Chinese cities: lack of adequate sewage treatment facilities.

Xiong Jianxin, an official in Beijing’s municipal water bureau, told the newspaper that some sewage plants on the outskirts of the capital are easily overwhelmed. While plants are built to handle up to 550,000 tons of water daily, at peak times they send as many as 100,000 tons of unprocessed sewage daily back into rivers or channels. Officials in several other large cities shared similar horror stories.

More than 40 percent of China’s arable land degraded: Xinhua | Reuters

More than 40 percent of China’s arable land is suffering from degradation, official news agency Xinhua said, reducing its capacity to produce food for the world’s biggest population.

The rich black soil in northern Heilongjiang province, which forms part of China’s bread basket, is thinning, while farmland in China’s south is suffering from acidification, the report said, citing agriculture ministry statistics.

Degraded land typically includes soil suffering from reduced fertility, erosion, changes in acidity and the effects of climate change as well as damage from pollutants.

Beijing is growing increasingly concerned about its food supply after years of rapid industrialization resulted in widespread pollution of waterways and farmland.

The country, which must feed nearly 1.4 billion people, has already outlined plans to tackle soil pollution, said to affect around 3.3 million hectares of land.

But as rising incomes place growing pressure on its domestic resources to produce more, high quality food, it is also planning to tackle degraded soil, the report said.

The agriculture ministry wants to create 53 million hectares of connected farmland by 2020 that would allow it to withstand drought and floods better, said Xinhua. Larger farms are more suited to irrigation and other modern farming practices.

It also wants to strengthen the monitoring of arable land management and speed up the legislative process to protect farmland in order to ensure stable food production and farmers’ incomes, the report added.

Currently protecting farmland is difficult as liability for soil contamination is hard to determine, experts say.

The government is drafting a new law to tackle this but it is not expected to be completed until at least 2017.

Pollution in Delhi Prompts U.S. Embassy Warning – India Real Time – WSJ

If you have children in New Delhi, you might not want to let them play outside today. The U.S. Embassy in the Indian capital said air quality – as measured at a monitoring station in the embassy compound – had reached “very unhealthy” levels on Wednesday morning.

On Wednesday at 10 a.m., the embassy said its air-quality index was 255 – a measure based on the amount of fine particulate, or PM 2.5, in the air. Such small particulates can enter the lungs and blood stream. They have been linked to severe health problems such as lung cancer.

The U.S. Embassy’s website said that an air-quality index reading between 201 and 300 can cause “significant aggravation of heart or lung disease” and a “significant increase in respiratory effects in general population.”

“Older adults and children should avoid all physical activity outdoors,” it said. “Everyone else should avoid prolonged or heavy exertion.”

The message though hadn’t got through to the American Embassy School in Delhi on Wednesday morning. Kailash Sharma, a staff member at the school, which is located across the road from the embassy, said by telephone that “kids were playing outside.”

The U.S. embassy in Beijing, China, also monitors air pollution.

Delhi’s air quality often deteriorates in winter, particularly in the days after the festival of Diwali when residue from fireworks displays adds to pollution levels.

India’s Ministry of Earth Sciences on Wednesday said its air-quality index was 121, a level described as “poor.”

China approves plan to combat climate change – China – Chinadaily.com.cn

The Chinese central government on Friday approved a plan that maps out major climate change goals to be met by 2020.

The State Council, China’s cabinet, gave a green light to the plan, which was proposed by the National Development and Reform Commission (NDRC), the country’s economic planner. A statement released on the State Council’s website urged the NDRC to carry out the plan.

China has pledged to reduce its carbon emission intensity, namely emissions per unit of GDP, by 40 percent to 45 percent by 2020 from the 2005 level. It will also aim to bring the proportion of non-fossil fuels to about 15 percent of its total primary energy consumption.

Other targets include increasing forest coverage by 40 million hectares within the next five years.

The government will speed up efforts to establish a carbon emission permit market, under the plan, which also calls for deepened international cooperation under the principles of “common but differentiated responsibilities,” equity and respective capability.

The State Council said local governments and departments at all levels should recognize the significance and urgency in dealing with climate change and give higher priority to action on this issue.

China’s release of the action plan came just before a climate summit to be held at UN Headquarters in New York on Tuesday. Chinese Vice Premier Zhang Gaoli will attend.

Xie Zhenhua, deputy chief of the NDRC and the country’s top official on climate change, told a press conference that the plan was concrete action by China to participate in the global process to tackle climate change.

By the end of last year, China had reduced carbon dioxide emissions per unit of GDP by 28.56 percent from 2005, which was equivalent to saving the world 2.5 billion tonnes of carbon dioxide emissions, Xie said.

At the end of 2013, China’s consumption ratio of non-fossil energy to primary energy stood at 9.8 percent. Forest growing stock had increased by 1.3 trillion cubic meters from 2005 to two trillion cubic meters, seven years ahead of schedule, according to the official.

In the first nine months of 2014, China’s energy consumption per unit of GDP dropped by 4.2 percent year on year and carbon intensity was cut by about 5 percent, both representing the largest drops in years, he said.

As a developing country, China is the world’s largest greenhouse gas emitter. With the plan, the country has showed its confidence in achieving its green goals.

Give the public a role in Clean Ganga project, says Rajendra Pachauri

India’s holiest river is due for a clean-up, with Prime Minister Narendra Modi taking personal responsibility for restoring the Ganga and ridding the 2,500 km long river of industrial effluents and untreated sewage.

Uma Bharti, Modi’s minister for water resources and Ganges rejuvenation, has said the river would be clean in three years. Earlier this month, India’s Supreme Court asked the government for a roadmap on the project so that the court could monitor it.

Rajendra Pachauri, chairman of the U.N.’s Intergovernmental Panel on Climate Change (IPCC), spoke to Reuters on the Ganga project, the need for transparency and how the public could help.

When China Cleans Its Air, Health-Care Costs Plummet – Businessweek

Beijing residents checking the hourly air-quality index online and strapping air-pollution facemasks on their children may miss the halcyon days just before the 2008 Olympics, when the city temporarily cleaned up its skies (at least, relatively speaking). But not every city in China has seen the air grow darker over the past half decade.

The northern city of Taiyuan, capital of coal-rich Shanxi province, has launched several measures to reduce coal burning and emissions. Although its skies are hardly clear, they are clearer. And that has made a noticeable difference in health outcomes and health-care costs, according to a new study published in the journal Environmental Health.

Over the past decade, Taiyuan has closed several large coal-burning power plants and increased environmental monitoring of its other factories—effectively lowering the average concentration of PM 10 (particulate matter 10 micrometers in diameter or less). As a result, average PM 10 concentrations dropped more than 50 percent from 2001 to 2010.

The economic costs associated with pollution—including health-care expenses, loss of labor productivity, and premature death—correspondingly dropped more than 50 percent, according to estimates by the researchers. Specifically, the researchers correlated reduced air pollution over the course of a decade with 141,457 fewer hospital or doctor visits, 31,810 fewer hospital stays, 969 fewer trips to the emergency room, 951 fewer cases of bronchitis, and 2,810 fewer premature deaths.

Beijing cuts coal use by 7 percent in first half of year – China – Chinadaily.com.cn

Beijing cut coal consumption by 7 percent in the first half of 2014 as part of its efforts to tackle smog, the city’s environmental protection bureau said.

Beijing cuts coal use by 7 percent in first half of year

Beijing is at the front line of a “war on pollution” declared by the central government earlier this year in a bid to head off public unrest about the growing environmental costs of economic development.

The city has already started to close or relocate hundreds of factories and industrial plants.

It will also raise vehicle fuel standards and is mulling the introduction of a congestion charge.

To reduce coal consumption, it is in the process of shutting down all of its aging coal-fired power plants and replacing them with cleaner natural gas-fired capacity or with power delivered via the grid.

Based on last year’s coal consumption level of 19 million metric tons, the 7 percent cut would amount to around 1.33 million tons per year.

Beijing has said previously that it plans to reduce total coal use by 2.6 million tons in 2014, and aims to slash consumption to less than 10 million tons per year by 2017.

The Beijing environmental bureau said the city had cut sulfur dioxide emissions by 5.4 percent over the first six months of the year.

It also took 176,000 substandard vehicles off the road.

Previous data issued by the Ministry of Environmental Protection showed that concentrations of hazardous airborne particles known as PM2.5 stood at 91.6 micrograms per cubic meter in Beijing in the first half of the year, down 11.2 percent year-on-year but still more than twice the recommended national limit of 35 mcg.

Much of the pollution that hits Beijing drifts in from the surrounding province of Hebei, a major industrial region that is home to seven of China’s 10 most polluted cities.

Under new plans to integrate Beijing with Hebei and the port city of Tianjin, the region will be treated as a “single entity” with unified industrial and emission standards.

Hebei said last week that it had cut coal consumption by 7.53 million tons in the first half of 2014, amounting to just over half of its target of 15 million tons for the year.

The province agreed last year to cut coal use by 40 million tons by 2017, and it is also planning to shed at least 60 million tons of excess steel capacity over the same period.

China provinces on track to meet 2015 energy targets: NDRC | Reuters

Most of China’s provinces are ahead of schedule or on track to meet 2015 energy savings targets, the government said on Friday, with Beijing and Shanghai among the frontrunners as the world’s No.2 economy seeks to reduce its impact on the environment.

China has pledged to reduce its energy intensity – the amount of energy it uses to add a dollar to its gross domestic product (GDP) – to 16 percent below 2010 levels by 2015.

Beijing’s intention in setting the targets was to slow emissions of climate-changing greenhouse gases and cut expensive fuel imports, but they have won new relevance with the pollution crisis that has enveloped the nation the past two years.

In China, Wastewater Irrigates Parks and Spreads Bacteria – Businessweek

In theory, recycling water in China’s parched cities, including Beijing, makes ecological sense. But when wastewater is inadequately treated before being used to water urban parks—or redirected through scenic downtown canals—it can become an environmental health hazard.

Something Is Scary in the Water That Irrigates Many Chinese Parks

Six researchers in Beijing and Xiamen working for the Chinese Academy of Sciences recently decided to compare conditions in city parks watered with fresh water vs. recycled water. Their findings, reported in a July 24 article in the journal Environmental Science & Technology, may make you squirm.

Conventional wastewater treatment plants are designed to remove solids, organic matter, and nutrients from water, but they aren’t properly equipped to treat the kinds of waste that may be found in used water from hospitals and pharmaceutical facilities. In particular, most wastewater plants in China don’t remove traces of antibiotics and may even become “reservoirs” for them, as the researchers put it.

Even treated wastewater can therefore become a vector for spreading antibiotics, as well as “antibiotic resistant genes”—chance genetic mutations that make bacteria resistant to drugs. The researchers found that urban parks in China doused with recycled water contained dangerously elevated levels of antibiotic resistant genes, with quantities from 100 times to 8,655 times greater than in other parks.

An April 30 report from the World Health Organization sounded the alarm about growing antibiotic resistance worldwide: “This serious threat is no longer a prediction for the future, it is happening right now in every region of the world. … Antibiotic resistance–when bacteria change so antibiotics no longer work in people who need them to treat infections–is now a major threat to public health.”

Apparently lousy sewage systems and some irrigated parks in China, and likely elsewhere, are helping to accelerate the threat. China’s situation is particularly risky because of a culture of rampant overprescription of antibiotics, which the government is trying hard to bring under control.
