BEIJING -- A key air pollutant has increased in China this year, highlighting the serious challenges faced by the world's biggest emitter of greenhouse gases as it tries to curb pollution, a senior Chinese official said Thursday.
Sulfur dioxide emissions rose by 1.2 percent year-on-year in the first quarter of 2010, the first such increase since 2007, Zhang Lijun, vice minister for environmental protection, told a news conference. "This sounded the alarm for our emissions reduction work and showed that the situation is not very optimistic," he said.
Zhang attributed the sulfur dioxide rise to a rapid increase in the manufacture of energy-intensive industrial products - those made in coal-fired factories like cement, aluminum and steel - as China rebounds from the global downturn. Industrial output was up 19 percent in the first quarter over the same period last year as the country's economy expanded.
Zhang also cited a decline in attention to pollution by local governments and companies and a drought in southwestern China.
