Yulin city, abundant in energy and resources, is an energy and chemical base, but fronts severe environmental impacts from energy and resources development. This paper, based on 2008 data, analyzes the environmental issues induced by energy and resources development, and estimates the environmental expenses from environmental pollution loss and ecological loss, both up to 12.65 billion RMB, 12.5% of GDP, of which 0.92 in environmental pollution loss and 11.73 in ecological loss. Nearly developing every ton of energy (coal, oil) will lead to 78 RMB of loss in environment and economy. It is of significance to estimate the environmental loss for sustainable development points such as environmental protection, green GDP, and ecological compensation.
