Environmental Management Evolution Framework
提出了一个企业环境管理演进的定性模型，通过定义成熟阶段和因果影响来评估环境管理水平，帮助企业理解非技术要素（如高层承诺）的重要性。
Environmental management has become a fundamental concern for organizations, customers, and citizens, yet there are few environmental management metrics that guide toward environmental excellence. This research presents a detailed qualitative model of the evolution of environmental management of a firm through the definition of maturity stages and causal influences. The model provides a technique for assessing maturity stages as well as steps that can assist or negate their ecological advancement. The causal-based classification helps companies to understand the need for nontechnical elements in the process, such as top management commitment. This article also contributes to the literature on integrative multimethod research, as it brings together several approaches to environmental management.
