Space-borne observations of vegetation greenness show a large increase with time over this study period, supporting the timing and increase in the land carbon sink over these afforestation regions. These large-scale changes reflect the expansion of fast-growing plantation forests that contribute to timber exports and the domestic production of paper 7. These provinces have established a pattern of rapid afforestation of progressively larger regions 5, 6, with provincial forest areas increasing by between 0.04 million and 0.44 million hectares per year over the past 10 to 15 years. Our estimate reflects a previously underestimated land carbon sink over southwest China (Yunnan, Guizhou and Guangxi provinces) throughout the year, and over northeast China (especially Heilongjiang and Jilin provinces) during summer months. Using these data, we estimate a mean Chinese land biosphere sink of −1.11 ± 0.38 petagrams of carbon per year during 2010 to 2016, equivalent to about 45 per cent of our estimate of annual Chinese anthropogenic emissions over that period. Here we present recently available data on the atmospheric mole fraction of CO 2, measured from six sites across China during 2009 to 2016. Understanding of Chinese land biosphere fluxes has been hampered by sparse data coverage 2, 3, 4, which has resulted in a wide range of a posteriori estimates of flux. China is currently the single largest emitter of CO 2, responsible for approximately 27 per cent (2.67 petagrams of carbon per year) of global fossil fuel emissions in 2017 1. Limiting the rise in global mean temperatures relies on reducing carbon dioxide (CO 2) emissions and on the removal of CO 2 by land carbon sinks.
