The definition, connotation, development trend, and main progress of eco-materials are introduced. Adding environmental component to conventional materials and continuous innovation of eco-materials will be the major sustainable research and development trends for materials industries and their key stakeholders. Eco-materials are the substantial foundation of circular economy and low-carbon economy. Eco-design is the guiding philosophy for sustainable materials development and innovation. Life Cycle Assessment is a powerful tool to measure the progress of sustainability of materials and their industries. The nomenclature of eeo-materials has been continuously evolving; and it is always categorized to type of materials relevant to conventional ones. Once the eco-friendly character becomes a basic feature for materials, there will be no need to highlight the specific type of eco-materials. Materials will be the eeo-materials that possess the eco-friendly feature; and that＇s exactly the long-term goal of materials research and development.%阐述了生态环境材料的概念与内涵，发展的动向和取得的主要进展，指出生态环境材料和传统材料的生态化改造是今后材料及其产业可持续发展的方向。材料是保证循环经济、低碳经济得以发展的物质基础，『斫生态设计则是实现材料和产品生态化改造和持续发展的指导思想。LCA（Life Cycle Assessment）是评价材料及其产业可持续发展进程的有力工具。生态环境材料是一种与原有的材料相比较而产生、相比较而发展的新型材料，其判断和认知，往往是相对的、动态的和不断发展的。当普遍地把环境协凋性作为所有材料必须具备的属性之一时，生态环境材料的提法也就失去了其单独存在的意义：材料即为生态环境材料，这正是材料所追求的长远目标.
