In order to minimize CO2 emission from iron and steel-making processes to abate greenhouse gas impact, the considerations and some practice of science and technology as well as its strategy completed and on going in Chinese steel industry are summarized. Two available ways for the minimizing in China so far: (1) Minimizing carbon-consumption (fossil energy-saving) in all the processes of steel industry which is the most realizable measure for reducing CO2 emission. (2) To look for new alternative reaction medium in the processes where producing more C02 like Ha in blast furnace etc and new processes for iron and steel making which discharge less CO2 . Some new ideas like macro-based measures are put forward for minimizing CO2 emission in steel industry.

The current situation of Chinese steel industry, the multi-iron resources and its recovery as well as utilization were introduced in this paper. The main concerned research activities and technology in China were introduced as well. Some new considerations and suggestion were put forward to increase the use of various recycled iron resources and appropriate degradation of iron ore. A new suggestion was made to establish an international research center for the developing of ultra steel making process which uses more various iron resources and degradation iron ore.

The general situation of renewable energy and its application in China are introduced in this report based on the statistics data from the Chinese government which includes wind energy, hydraulic power energy, Ocean energy, geothermal energy, solar energy and the bio-mass energy (but not the utilization of tide energy, temperature difference energy in Ocean for power generation and salt concentration difference energy in Ocean for power generation). The future developing of some renewable energy in China is introduced in the report as well.
