This new year celebration is once more the occasion to burn tons of fireworks. This week should be a relief for our lungs as most of the factories are shutdown and as people do not have to commute for few days. But no, fireworks are here and create a nice city-wide smoke!
If you can't get the air cleaner, just change the way you measure!

The changes that occurred in the measurement and communication of Beijing air quality goes further than just not providing detailed data (see my previous post).
Beijing environment bureau decided to change a bit the way it measures the pollution: they removed stations downtown and created new ones in the country side. So there are still 27 stations and the average of the measures still gives the overall result for Beijing. However, among the new stations, there is one in Badaling and at Miyun reservoir.
For those not familiar with Beijing, Miyun reservoir is in the mountain, about one hour out of Beijing. As the water is to be drunk by millions of Beijingers, no activity is allowed next to the lake (neither industry nor transportation). For sure, the quality of the air there is among the best in all Beijing province!
Since probably 90% of Beijing (the province-like region) is outside the actual city, they could put 90% of the stations in the countryside, and still claim to have an accurate geographical a... [more]
Shanghai comparator up, Beijing comparator still down...

I took me quite some time to try having Shanghai and Beijing comparators up again.
For Shanghai, it's done, and the comparison is done as before.
For Beijing, it is not so easy. Since January 1st, Beijing Environment Bureau only provides the general index and the main pollutant. It is not sufficient to compare properly with other cities' indexes. Previously, we had the indexes for three pollutants (SO2, NO2 and PM10) with which we could calculate the concentrations. I keep trying to find a solution, but as we get closer to the Olympics, it will be harder to get reliable data...
hi! I just found your blog through Planet BLUG. Do you have any tips on mitigating the risk of living in such a polluted environment? I mean, we can't help but breathe the air. But are t... [more]

I have emphysema and will be in Beijing and Shanghai in June/July. Anybody know how I can get oxygen in these cities?
Beijing and Shanghai pollution websites have been updated over the new Year holiday. The comparator will be updated soon to adapt to those new versions.

Hi Severine, the links on the right side still work. However, on the Beijing site, the index is not clearly given. You have to click on the map and check the first line which means "sta... [more]
A step toward a common air pollution index in Europe!
Friday, 21 December 2007,
Written by Julien
I just discovered this website: www.airqualitynow.eu. It is an European webportal to compare air quality across borders.
I think that's a very good news for citizens' awareness about outdoor pollution. Right now, each country (and sometime each city) has its own index, making it really hard for normal people to understand and compare.
26 cities are already participating to this initiative. I hope more and more cities will join it, so Europe could have a well understood Common Air Quality Index!
I created the comparator on this website, so people could translate Chinese pollution in their national standard. I will soon add this CAQI in the comparator...
Hello !
Alors, on prend les paris... On en est à une semaine de la fin de l'année, alors est-ce que la municipalité de Pékin va tenir sa promesse de 245 jours de "ciel bleu" en 20... [more]
Pollution in China seen by NYT
Monday, 17 December 2007,
Written by Julien
The New York Times is free since few months only and that's definitely good news (you only need a free registration). They are currently publishing a really interesting series of articles about pollution in China.
It is actually part of a complete series called "Chocking on growth", which already has 8 long articles plus videos, dealing with subjects like water, air, Three Gorges dam...
The last article is about food, In China, Farming Fish in Toxic Waters. Read it and you will think twice before eating fish in China again! Picture: Chang W. Lee/The New York Times
Geoengineering, or how not to reduce CO2 emissions!
Saturday, 15 December 2007,
Written by Julien
World leaders are gathering in Bali, trying to agree on how to reduce CO2 emissions and how to limit climate change. Even if the talks result in an agreement setting a cap on emissions by 2020, the reduction of C02 in the atmosphere is a long term issue.
Other options are being developed to prevent climate change much quickly, by engineering the planet. Those geoengineers have many ideas such as injecting CO2 into oceans, storing CO2 in empty gas reservoirs, shielding the planet from the sun...
The more the planet heats, the less those options will seem surrealistic. The following video explains how to create sulfur clouds above the poles to reduce global warming, and explains how this could be integrated in an overall plan against climate change:
China already uses missiles to concentrate rains on Beijing. I guess they could easily propose their skills to reduce the impact of their emissions and to keep focusing on economical growth.
I went on this website to have a look on the huge fires in California. It is really impressive to see that the smoke is spreading all over the southern part of the state.
I also discovered that another hazard listed is the haze over Northern China:
Interestingly, there is not only haze (we are quite aware of that!) but there is also carbon monoxide:
Carbon monoxide is "odorless, colorless, and still toxic, and can be lethal in large amounts. Smaller amounts can cause fatigue, impaired vision, and nausea. Carbon monoxide additionally acts as a precursor smog and ground-level ozone."

Why Linux is good for environment?
Friday, 31 August 2007,
Written by Julien
Looking for solutions against pollution, I found a new one: using Linux and other free software! Now that Linux is user friendly, it is a real alternative for companies and individuals.
Linux has the following qualities for environment preservation:
No need for useless shiny boxes and manuals, every thing can be downloaded over internet,
No need for changing PCs every three years, latest version of Linux can easily run on 10 years old computers,
Reduce the energy consumed by computers, as Linux uses less system resources (less bugs, no anti virus, no virus and spyware...), less energy is required to run processes and to cool down PCs,
Reduce the transportation required for maintenance, almost everything can be maintained over network,
No need for big houses and 5 meter long cars for developers, Linux is still mainly made by geeks coding during their free time,
No advertisement, how many tons of paper were consumed to launch Windows Vista? Did you see anything for the release of Ubuntu during the same period?
So Linux means less computers and less energy consumed, and in addition it is FREE.
In term of environment preservation, do you know any drawback for using Linux?
Links:
Want to learn more about Linux, contact the Beijing Linux User Group,
A very user friendly Linux distribution, Ubuntu(free of course),
I do not want to compare Linux and Windows in term of usability. Some people prefer fighting against viruses and system instabilities. Others prefer understanding how computers work. That's a personal choice. Apple computers use BSD operating system (Unix family) and are quite optimized to reduce energy consumption. However, they are still developed by energy consuming developers and Apple use lots of paper for marketing.
Greetings!
