Why are some firms more environmentally proactive than their counterparts from the same industry? What are these factors, which are responsible for the adoption of proactive environmental strategies which are beyond the requirement of extant laws? The power sector is a critical sector for the development of infrastructure in a developing economy like India. The emissions from the power sector are a cause of concern for the environmentalists and stakeholders. Some firms are observed to be more environmentally proactive than others even though the regulatory requirements are same. This paper aims to identify the determinants of the adoption of proactive environmental strategies in the power sector in India. The available studies are generalised and very few are sector-specific. No such research is carried out specifically for the power sector in India. Statistical tools like SPSS (Statistical Programme for Social Science) and AMOS (Analysis of Moment Structures) are used to analyse the quantitative data collected through a questionnaire-based survey from major power sector companies. Reliability and validity of data collected are checked using Exploratory Factor Analysis. Subsequently, Confirmatory Factor Analysis is applied to identify the determinants of adoption of proactive environmental strategies. The identified determinants are ranked using Structural Equation Modelling. The study identifies institutional pressure, performance improvement, business practices, and market pressure and benefits as determinants. Institutional pressure and performance improvement emerge as determinants which are ranked higher as compared to other two. The specific contribution of the study is to provide an understanding for the policymakers in Indian power sector to recognise these determinants in the formulation of policies and guidelines for environmental protection.

为什么有些公司比同行业的公司更具环保意识？这些因素是什么，这些因素导致采取了超出现有法律要求的积极的环境战略？在印度这样的发展中经济体中，电力部门是基础设施发展的关键部门。电力部门的排放引起环保主义者和利益相关者的关注。尽管监管要求相同，但据观察，有些公司比其他公司在环保方面更具积极性。本文旨在确定在印度电力行业中采用主动环境战略的决定因素。现有的研究是概括性的，很少是针对特定行业的。没有专门针对印度电力行业的此类研究。诸如SPSS（社会科学统计程序）和AMOS（矩结构分析）之类的统计工具用于分析通过基于问卷调查的方式从主要电力公司收集的定量数据。使用探索性因子分析检查收集的数据的可靠性和有效性。随后，通过验证性因素分析来确定采用积极环境策略的决定因素。使用结构方程模型对确定的行列式进行排名。该研究确定了机构压力，绩效改善，业务实践以及市场压力和收益是决定因素。制度压力和绩效改善是决定因素，与其他两个因素相比排名更高。该研究的具体贡献是为印度电力部门的决策者提供了一种认识，使其能够在制定环境保护政策和准则时认识到这些决定因素。
