Abstract: Taking Dalian city as the research object, this paper measures the carbon footprint of energy consumption in Dalian city from 2010 to 2020, calculates the value of carbon footprint and carbon footprint intensity as well as the ecological pressure intensity, and analyzes the carbon emissions of the key industries with the data of Dalian city in 2019. The research results show that: (1) Based on energy types, petroleum is the largest, coal is the second and natural gas is the smallest in produced carbon footprint from 2010-2020; based on key industries, the power industry is the largest and the petrochemical industry is the second in produced carbon footprint in 2019; the energy utilization efficiency of Dalian city was improving from 2010-2014, and the output value of unit land area increased quickly with the economic value created by carbon footprint surpassing the growth rate of GDP, indicating that economic growth at this stage is independent of fossil energy. (2) The carbon footprint produced by various energy consumption and its percentage in 1995-2006 period decreases from coal to oil to natural gas, and the carbon footprint percentage produced by coal consumption decreases year by year while the oil and natural gas show the opposite.
