In the same period, China′s overall carbon dioxide emission intensity declined rapidly although this decline has slowed since 1999.
与此同时，二氧化碳排放强度总体上呈较快下降趋势，但1999年以后下降速度放缓。
Though a developing country, China started voluntary reduction of its emission intensity and set new targets for 2020 to further reducing its carbon intensity per unit of GDP by 40-45%.
中国虽然仍然是一个发展中国家，也自愿采取了降低排放强度的措施，并制定了到2020年进一步将单位GDP碳强度降低40-45%的目标。

The State Council said the country will reduce its "carbon intensity" by 40 to 45 percent by the year 2020,as compared to 2005 emission levels.

His ministry's calculations, which predate China's announcement, allegedly show that such emission-curbing steps could reduce the carbon intensity of India's economy by around 25% by 2020 compared with 2005 levels.
