　　China's top political advisory body has pledged to constantly offer wisdom and strength in support of the nation's ongoing efforts to foster a harmonious coexistence between humanity and nature.

　　Liu Jieyi, spokesman for the third session of the 14th National Committee of the Chinese People's Political Consultative Conference, made the remark at a news conference in Beijing on Monday, one day before the opening of the annual session.

　　Reflecting on the significant achievements China has made in promoting environmental and ecological conservation, Liu noted that CPPCC members have made proactive contributions to these areas of progress.

　　In 2024, the proportion of days with fairly good air quality nationwide reached 87.2 percent, while the ratio of surface water with fairly good quality increased to 90.4 percent, he noted.

　　China's air quality index uses a scale of 0 to 500, and values at or below 100 are considered fairly good quality with little potential to affect public health. The country has a five-tier quality assessment system for surface water, with Grade I being the best. Water with a quality of Grade III is considered fairly good.

　　In 2023, the proportion of days with fairly good air quality across the country stood at 85.5 percent, and the proportion of surface water with fairly good quality stayed at 89.4 percent, according to the Ministry of Ecology and Environment.
