Table 3 Calculation results of carbon emissions, vegetation carbon sinks, and carbon emissions intensity (CEI) on the city scale in 2013.

From: Spatial-temporal dynamics of carbon emissions and carbon sinks in economically developed areas of China: a case study of Guangdong Province

City

C emissions on new built-up land (TgC yr−1)

Total C emissions (TgC yr−1)

Total C sinks (TgC yr−1)

Ratio of total C emissions to sinks

Net C emissions (TgC yr−1)

CEI per unit land area (MgC yr−1 ha−1)

CEI per unit GDP (MgC yr−1 10−4 USD)
