Beijing’s Environmental Successes

A new report from the environmental watchdogs at Greenpeace says that Beijing has lived up to many (though definitely not all) of its green promises made in its bid to host the 2008 Summer Olympics.

As the Olympic Committee has noted, part of its selection decision was based on the hope that sustainable development would benefit China as it continues its crash course in rapid development. While there are many areas that could have been improved, sustainable development advocates are hoping that Beijing’s environmental successes will serve as a blueprint for other developing cities in China and around the world.

Greenpeace found that “Beijing achieved and in some cases surpassed original environmental goals but missed some opportunities that could have ensured a better short- and long-term environmental Olympic legacy for the city.”

Here’s a quick look at Beijing’s laudable green triumphs:

  • A Shift Away from Polluting Fossil Fuels
    New Olympic venues showcase an array of sustainable energy technologies, including solar hot water, geothermal heating and air-conditioning, and solar photovoltaic systems. And wind power from a new nearby wind power station will provide enough energy to meet the annual demands of 100,000 families.
  • New Energy Efficient Upgrades
    More than 32,000 household-heating systems have been upgraded from coal to electricity. And more than 50,000 large-scale boilers have been upgraded to be more energy efficient.
  • Stringent Vehicle-Emission Standards
    Ahead of what was originally promised, new vehicles must now meet EURO IV emission standards, which are among the strictest in the world.
  • Improved Public Transportation
    Four new rail lines have been added in Beijing. A fleet of new, natural-gas buses are running during the games. And fares have been reduced to encourage ridership, which now averages 19.5 million a day. (Olympic ticket-holders can ride free, for 51 days.)
  • Improved Wastewater, Water Reuse, and Sewage Systems
    Drinking water now meets World Health Organization (WHO) standards and new reusing technologies should help with increased water demand. Rural sanitation construction is set to protect groundwater supplies. And the government has cracked down on illegal construction, farming, and mining, which pollutes waterways.
  • Sponsors Going Green, Too
    Coca-Cola’s nearly 6,000 refrigeration units are HFC-free. (Hydrofluorocarbons replaced ozone-depleting CFCs in refrigeration units in the U.S. in the 1980s, but have since been pinpointed as a source of global warming because of their heat-trapping properties.) And Samsung is providing cell phones that are free of polluting polyvinyl chloride (PVC) and bromide flame retardants.

Overall, Greenpeace commends China and the city of Beijing for its efforts and for demonstrating that, given the political will, it is possible for a rapidly developing city to leap ahead of polluting technologies. But for any of the green initiatives to have any meaningful and lasting impact for China after the games, the country must engage in long-term energy reforms and move away from its dependence on hyper-polluting coal as an energy source.

Who Is Going To Win the Olympics?

Saturday, August 16th, 2008

If provided with another chance, would China have wanted to host the Olympics this summer?  If China knew that hosting the Olympics in 2008 would actually have a detrimental impact on its economy while bringing to the international spotlight the country’s environmental and human rights practices, would we be watching Istanbul 2008?

The International Olympic Committee selected Beijing to host the 2008 Summer Olympics back in 2001.  In generating support for the Olympics in Beijing, China argued, in part, that 2008 would be the creation of the first “green” Olympics.  Cleaning up Beijing for the 2008 games, Chinese officials suggested, would be an inspiration to other Olympic venues.  Seven years later, air quality is still a major concern to the athletes.  And if air quality was not enough to keep China from “breathing easy”, in February the United States Olympic Committee announced it would bring its own food to the Olympics.  Perhaps inspired in part by the worldwide food contamination scare for U.S. domestic pets, the decision disappointed Beijing nonetheless.  Add to that the recent scrutiny of China’s human rights and political practices, is this really what China needs right now?

Olympic Weather Control

In the years approaching the 2008 Games, the Chinese government formed a Weather Modification office to address weather and pollution concerns. The goal: Create optimum conditions by making it rain when they want and keeping it away when they don’t.

When the country first started fooling with Mother Nature, back in 1958, the primary focus was farm regions, where drought lingered and crops suffered. But over the decades the techniques they developed have been used to fight fires, prevent hailstorms, replenish riverheads and reservoirs, sweep away pollution and ease a heat wave.

Does that mean the grey haze over George Hincapie and other Olympic cyclists or the rain that fell on beach volleyball competitors were signs of China’s weather control success? When you consider the clear skies over the Opening ceremony…maybe.

Why Air Pollution Matters to Athletes

Monday, August 11th, 2008

The flap over Beijing’s air pollution levels during the 2008 Summer Olympics has us wondering: what are the real implications for athletes? And what do air pollution levels mean for the rest of us?

Most people will tell you they can feel the effects of a particularly smoggy day, but air pollution is of particular concern to athletes, especially those who participate in endurance sports like long-distance running and cycling.

Athletes Take in More Air

Athletes breathe in up to 20 times more air than sedentary individuals, which means they breathe in up to 20 times more pollutants. When pollutants make up a higher percentage of air, it also means less oxygen is taken in, which could affect an athlete’s performance.

Once air pollutants (called “particulate matter” or PM for the tiny harmful particles and liquid droplets that make up pollution) are in the lungs, they cause irritation and inflammation and can exacerbate existing heart, pulmonary, or respiratory conditions such as asthma. Common reactions are coughing, breathing difficulties, eye irritation, chest pain, and darkened mucous secretions. More serious reactions include asthma attack, heart attack, even death.

The Worst Pollution Is the Kind You Can’t See

The most harmful particles measure less than 10 micrometers in diameter and are called PM10. (For size reference, a human hair measures about 70 micrometers in diameter.) High PM10 levels are particularly dangerous because the particles are small enough to lodge deep in the lungs and sometimes even enter the bloodstream.

When you hear reporters talk about air pollution levels, they are usually talking about the amount of PM10 in the air. That’s how Chinese officials are measuring their success at reducing air pollution during this week’s Olympic events. Beijing’s goal is to reach 50 micrograms of PM10 per cubic meter. A typical day in Beijing can measure 250 micrograms, so it’s a laudable, if difficult to achieve benchmark. (A typical day in London measures 21 micrograms.)

How to Reduce PM10 Levels

So what can you do to reduce PM10 in the air? Most PM10 comes from cars, power plants, and factories, so you can make the biggest impact by driving less and using less electricity. Perhaps the even bigger lesson in Beijing, however, is that voluntary measures have great limitations. It wasn’t until severe restrictions were placed on drivers, utilities, and manufacturers that air quality improved.

The International Olympic Committee is hoping that many of Beijing’s green measures will improve the environmental quality of life after the games are over. How Beijing fares will serve as a lesson for the rest of world.

Israeli Red and Green: Balancing War in the Middle East with Global Sustainability

Monday, August 4th, 2008

Two years ago last month Israel and Hezbollah went to war.  To some in the outside world, and many Israelis, the 33-day battle was seen as an Israeli defeat.  Just last month Israel agreed to exchange Hezbollah and Palestinian prisoners (considered by Israel to be terrorists) for the bodies of the two Israeli soldiers whose capture in 2006 sparked the original crisis.  Immediately following the exchange, Hezbollah celebrated in the streets of Beirut showing off its power.

Seen by some in the outside world as the end of a once-legendary reputation for avenging the deaths of Israelis killed by terrorists, this most recent trade has drawn considerable criticism to the government of Israeli Prime Minister Ehud Olmert (six months before the 2006 war, Israel’s Prime Minister Ariel Sharon suffered a stroke, and his authority was immediately transferred to Olmert, then Israel’s Vice Primier and Sharon’s protégé).  Still, some see Hezbollah victorious on the propaganda front but not the Israel/Lebanon border.

For the past two years the Israeli Knesset has investigated the handling of the war against Hezbollah, including the establishment of a special commission.  Recently announcing his resignation in September, Olmert never really recovered politically from the war with Hezbollah.  And while the future of Israel’s military dominance in the Middle East may face additional challenges from Hezbollah and more recently Iran, the overall political turmoil in the region has eclipsed some very important and seemingly unnoticed significant Israeli advances on a non-military front, namely the environment.

All Hospitals Are Green, But Some Are More Green Than Others

Hospital

Other than a possible seismic issue here and there, and maybe some other obvious exceptions (we’ll just let that surgeon wash those hands and arms with the water running for a full 300 seconds, just in case), healthcare facilities around the nation are jumping on, and occasionally off, the green bandwagon.  Green is clean, and nobody likes a dirty hospital. Indeed, it is the fantasy of every soon-to-be hospital patient that he or she is greeted at the door by Florence Nightengale and then whisked away to a private, state-of-the-art patient room complete with satellite television and high speed internet.

Being a green hospital, however, is not so easy, and many of the suggested green practices may actually compromise patient care.  Green cleaning products, mercury, lighting and basic hospital equipment are just four of many examples currently waiting at that crossroads where “green” public policy and generally accepted healthcare practices collide.

Beijing Olympics Not Breathing Easy

Tuesday, July 29th, 2008

With just days to go, China’s government is working overtime to meet air pollution reduction goals set for the upcoming Olympic games in Beijing.

Named the world’s 13th most polluted city by the World Bank, Beijing has implemented stiff measures to reduce its infamous air pollution, including:

  • Tightening emission standards on cars
  • Temporarily restricting traffic in Beijing
  • Temporarily halting some construction projects
  • Ordering some high-polluting factories to temporarily stop work
  • Updating coal-burning plants

And while the measures have had some effect—Chinese government officials say Beijing’s air pollution is down 20% from 2007—it may not be enough. Due in part to warm, dry weather and a lack of wind during the past week, Beijing’s air pollution index is twice the maximum recommended by the World Health Organization.

If pollution levels keep up, the government says it is prepared to further restrict driving in Beijing (taking up to 90% of the city’s private cars off the road), halt more construction sites, and order more factories to shutter operations during the games.
