In June 2015 the Chinese government officially launched the declarationstrengthening action on climate change-China national independent contributionwith a commitment that until 2030 per unit GDP carbon emissions will be reduced by 60%~65% compared with 2005 levels and the non-fossil energy of primary energy consumption ratio will reach 20%.Under energy consumption growth,there are only two pathways to fulfill the promise of energy conservation and emission reduction(ECER)toward 2030.First,reconstructing the industrial structures to optimize energy structure,called a static ECER.Second,promoting the progress of scientific innovation and technical progress to reduce carbon emission factors per unit of energy consumption,called a dynamic ECER.Moreover,the dynamic ECER can be defined into three perspectives:(1) increasing the supply of nuclear energy,hydroenergy,wind energy,solar energy and geothermal energy,relying on comprehensive and systematic innovation and progress of engineering technology;(2)promoting the technology and equipment innovation in major energy intensive industries to further raise the oxidant factor of fuel energy and transfer efficiency of energy consumption;and (3)expanding the scale of raw material substitution and consumption by developing new material and process engineering.We focused on four major energy intensive industries:electricity,iron and steel,transportation and building materials,to discuss the prospect of ECER by 2030 based on three perspectives of dynamic ECER.Technical progress plays a vital role in promoting ECER until 2030,whereas it is difficult to create a revolutionary impact.A more reliable roadmap to lead the development of ECER in major energy intensive industries,with more concern on multiple solutions for technical application and improvement.
