From The Wall Street Journal:
Chinese officials defended the accuracy of pollution data and reaffirmed their ability to make the Beijing Games a “green Olympics,” even as the capital remains mired in gray haze less than a month before the opening ceremony.
Separately on Thursday, the government announced it will roll out free public transportation for Olympics ticket holders, the latest measure aimed at reducing traffic during the Games and cutting the polluting emissions from Beijing’s more than three million cars.
Beijing officials claim to have significantly improved air quality, with just over two-thirds of the days last year meeting national health guidelines, up from only 20% a decade earlier. But some analysts have charged that pollution standards have been loosened, air-quality-monitoring stations have been moved and data have been manipulated to show better results.
