More and more carbon emissions (CE) were produced and arose from the direct energy consumption in Gansu’s construction industry. So, we first computed the CE of Gansu’s construction industry during 2000-2017 in this paper, and then used the Logarithmic Mean Divisia Index (LMDI) model to decompose the driving factors of CE. The results showed that: (1) the CE of Gansu’s construction industry increased from 95.44 × 10 4 t in 2000 to 127.84 × 10 4 t in 2017, with the annual growth amount of 1.91 × 10 4 t and rate of 2%, respectively. (2) The economic development level effect was the dominant driver to promote the CE of Gansu’s construction industry followed by the employment population effect, with the contributions of 100.61 × 10 4 t and 44.03 × 10 4 t. However, the energy intensity effect played the most primary role in inhibiting the CE growth, which followed by the energy structure effect, with the contributions of -107.25 × 10 4 t and -4.99 × 10 4 t, respectively. Based on the above conclusions, some mitigation implications for the low-carbon development of Gansu’s construction industry were put forward.
