Analysis Of Iron Material Flow And Implicit Carbon Emissions Transfer In Iron-containing Commodities Trade

Iron resources are an important pillar industry for the development of the national economy.However,due to the limited development of iron resources between countries and the development of steel-related industries,iron products in many countries cannot be self-sufficient and can only rely on trade to make up for the demand gap.This has resulted in a global trading system.At the same time,the steel industry is also a high-pollution,high-emission,high-energy-consuming industry.The carbon emission problem of the steel industry has become an important factor affecting its sustainable development In particular,the issue of carbon emissions through international trade has become a widespread Focus on the topic.In the context of global economic integration,countries continue to transfer iron material flows and implied carbon emissions through international trade.This study uses the material flow theory to establish a model of iron material flow and implied carbon emissions for international trade in iron-containing commodities through analysis of the steel industry chain.Analyze the global iron material flow and the pattern of implicit carbon emissions and cross-regional flows,discuss the situation of major countries,make reasonable suggestions for optimizing the steel industry structure,and win the right to speak for many countries at the global climate conference..The main contents of this study are:(1)constructing the whole life cycle framework of the iron material flow industry chain,and finding out the key joints of the iron and steel industry chain;(2)constructing the special material flow model and implicit carbon emission model of iron-containing commodity international trade;3)Analysis of iron material flows and implied carbon emissions in international trade of iron-containing commodities in the world,and specific analysis of major countries;(4)Steel industry from the perspective of iron-containing commodity trade and implicit carbon emissions transfer Suggestions for chain optimization.Research shows that the total amount of iron in the global iron-containing commodity trade in 2016 was 1.611 billion tons.The total amount of iron ore accounts for more than half,followed by steel and steel products.Asia and Europe are the main import areas for iron resources,and Oceania and North America are the main export areas for iron resources.There are large differences in the types of iron resources imported and exported and the varieties of demand in different regions of the world.Many regions,represented by Asia and Europe,have formed a trade pattern of imported raw materials and exported products",In 2016,the total implied carbon emissions of global iron-containing commodities trade was 1.28 billion tons.Among them,steel and steel products are the main enussion links.Europe and Asia are the largest import and export areas for implied earbon emissions.North Ameriea is the third largest import and export area for carbon emissions.And the major importing countries and major exporting countries in different parts of the steel industry chain are very different,and different countries play different roles.At the end of the paper,the paper proposes policy recommendations from the trade and environmental responsibility of iron-containing commodities:improving the trade structure;resolving excess production capacity;maintaining reasonable interests;and promoting technological innovation.
