Using ecological footprint and decomposition analysis models, energy ecological footprint (EEF) from 2000 to 2008 in Bohai Rim Region was calculated. The EEF change and the impact factors were also analysed. The results showed that the EEF increased continuously from 2000 to 2008. The total values of EEF increased to 4.578×108 hm2 in 2008 from 2.159×108 hm2 in 2000, and the values per capita increased to 1.946 hm2 from 0.974 hm2. These contributed 50-60 percent of regional total ecological pressure. In all contribution factors, GDP growth was highest, energy structure and population size were inferior, and energy strength was lowest. Though the energy strength was decreased continuously, this was not enough to counteract the ecological impact derived from immoderate energy structure and consumption level. This led to energy ecological footprint in Bohai Rim Region increasing continuously.
