| Abstract: | The general principle and calculation model of ecological footprint was introduced, and the idea of "life cycle assessment" was added into the model to calculate the ecological footprint of an enterprise. The ecological footprint and the ecological efficiency of an enterprise in Chengdu were calculated. The results indicated that the ecological footprint of this enterprise was 230.66 ha, energy, water and materials occupied the largest ecological footprint, their proportion was 93.5%; the ecological efficiency of this enterprise was high to 472 384 yuan/ ha. This research can indicate quantitatively the ecological efficiency of an enterprise and the impacting factors, and show the main methods to decrease the enterprise's ecological footprint and heighten the enterprise's ecological efficiency. |
