All mankind is faced with the severe challenge to deal with climate change. Advocating the concept of “a community with a shared future for mankind,” China has taken the initiative to commit itself to emission reduction and has actively contributed its strength. According to the data on agricultural carbon emissions, it finds that non-carbon dioxide gases dominated agricultural carbon emissions, showing an overall upward trend year by year. However, a downward trend has been seen, and it was near a peak in this regard in recent years. Emissions from energy consumption of agricultural machinery may become the most significant uncertain factor for the carbon dioxide peaking of agriculture, as agriculture in China is yet to be mechanized further. The analysis above has laid a foundation for the emission reduction idea of driving the green transformation of agriculture with low-carbon measures. Specific recommendations are as follows in this regard. Carbon constraint indicators should be added to the 14th Five-Year Plan for the development of agriculture and rural areas. The methodology accounting should be expedited for agricultural carbon emissions. China should make a lot of effort to develop the agricultural carbon market and strive to employ financial means to promote low-carbon agricultural technologies.
