Low-carbon popular science education serves as an important way to build a low-carbon and sustainable society engaged by the public. The paper explores the current situation, the daily low-carbon behaviors and the expectations about the low-carbon popular science education of primary and middle school students in counties of Guangxi Zhuang Autonomous Region. The results found in the paper reveal that: Firstly, due to a lack of the low-carbon popular science education in counties, the students rarely take part in the low-carbon popular science education. The students in primary and middle schools don't understand most of the low-carbon vocabulary. The low-carbon popular science education is mostly carried out in schools and networks. The most popular ways of the low-carbon popular science education are teachers' lecturing and reference books reading, while the least popular way is visiting the low-carbon popular science education venues. The most impeding factors for low-carbon popular science education are that there no activities about popular science and that the students are burdened with busy and heavy study tasks and homework. Secondly, the judgment of the low-carbon behaviors of primary school students is not high. The low-carbon behavior of junior high school students is better than that of the primary school students. The low-carbon behavior of high school students is the best among them. Thirdly, the students in primary and middle schools expect that low-carbon popular science education should be conducted more frequently. The most expected ways are the popular science games and the visits to the popular science venues. The countermeasures and suggestions of low-carbon popular science education in counties have been proposed in the last part, which provides the empirical evidence and reference to the low-carbon popular science education conducted in the counties.
