Abstract:

Water-carbon nexus is one of the important research fields of regional sustainable development. Studies on industrial carbon and water footprint efficiency from the perspective of water-carbon coupling not only help reveal the impact mechanism of the resource consumption intensity and efficiency on industrial carbon emissions, but also have great significant practical meanings for reducing water and carbon emissions in regional industrial transformation under the background of globalization. By the method of input-output analysis, input-output table of Henan in 2012 and industrial water and energy consumption data were applied to discuss industrial carbon and water footprint efficiency in this paper. The conclusions are as follows: (1) Carbon and water footprints of different industries are unmatched. The agricultural water footprint is the largest, which is 2333 times of the water footprint of lumbering. The carbon footprint of extractive industry is the largest, which is 273 times of food industry. (2) There are obvious differences among industrial water and carbon footprint efficiency. In general, the water/carbon footprint efficiency is lower in the industries with higher water/carbon footprint. (3) The different water/carbon footprint efficiency among different industries were mainly influenced by industry attribute, water and carbon consumption intensity, energy structure, technological level and relationship between industries, etc. (4) In the future, Henan province should make differentiated water-saving and carbon emission reduction policies in industrial development by combining the characteristics of different industries and the water-energy nexus, strengthening institutional constraint and legal supervision, promoting water and energy efficiency of enterprises, and enhancing regional adaptation and mitigation capacity under climate change.
