[Objective] The impacting factors of energy consumption's carbonemissions and water resource consumption were explored, and the change in the future of Jing-Jin-Ji region was analyzed to provide scientific support for making targeted policies.[Methods] Based on the estimation of carbonemissions from energy consumption in the Jing-Jin-Ji region from 2002 to 2012, this study established the factor decomposition models of carbonemissions from energy consumption and water resource consumption. It also set the scenarios analysis model to forecast carbonemissions from energy consumption and water resource consumption in 2020.[Results] (1) Carbonemissions from energy consumption of Jing-Jin-Ji region increased with an average annual rate of 8.5%, the accumulation rate was 226.26%. The main emissions was from industry sector, and the followings were transportation and residential life sectors. Water resource consumption was relatively steady in all three industries. (2) Change of per capita wealth was the most positive factor for both CO₂ emissions and water resource consumption of Jing-Jin-Ji region. While energy intensity and water intensity were two of the most negative factors, and the followings were industrial structure, per capita water resource consumption, population and carbon emission coefficient. (3) Under all scenarios, CO₂ emissions in 2015 and 2020 will increase 553.6 Mt and 819.2 Mt in comparison with the one in 2005, respectively. Water resource consumption will increase 3.36 and 9.97 billion m³in comparison with the one in 2012.[Conclusion] Water resources consumptions of three major industries in Jing-Jin-Ji region during the study period were relatively stable, which implied that the adjustment of industrial structure and improvement of industrial water use efficiency are the priority for regional water resources management of this region.
