本研究針對台灣上市櫃公司探討環境績效、綠色環境管理策略與公司績效之間關係。實證結果發現，用水量降低、用電量降低與碳排放量降低與公司績效皆呈顯著負向關係；但用水密集度降低、用電密集度降低與碳排放密集度降低皆與公司績效呈顯著正向關係；另企業採用綠色環境管理策略（ISO14001, ISO14064, ISO50001）可強化公司用水密集度降低與碳排放密集度降低與公司績效之正向關係及弱化用水量降低、用電量降低與公司績效之負向關係。

This study aims to understand the relationships among environmental performance, green environmental management strategy and firm performance in Taiwan. The results show the relationship between water usage reduction, electricity usage reduction, carbon emissions reduction and firm performance is significantly negative, in contrast, the relationship between water intensity reduction, electricity intensity reduction, carbon intensity reduction and firm performance is significantly positive. Futher, the firms which adopt green environmental management strategy enhance the positive relationship between water intensity reduction, carbon intensity reduction and firm performance, and weaken the negative relationship between water usage reduction, electricity usage reduction and firm performance.

隨著國際間重視節能減碳趨勢、相關法規相繼制訂，利害關係人日益關注企業如何調適氣候變遷與能源短缺導致的負面影響，企業在經營方面需慎選環境績效與環境管理策略以轉化為企業競爭力並使公司獲利。 根據實證結果可獲得以下之管理意涵與研究貢獻： 節能減碳是因應時勢所需的重要環境績效，在政策推動與企業自覺的認知下，強調節能減碳的企業有增加的趨勢。由本研究涵蓋台灣上市櫃27種產業所蒐集之公開數據為樣本，應可反映在地化企業之真實現況。研究結果顯示，企業節能減碳績效對於公司財務績效具有顯著影響，但存在重大歧異，就使用效率而言，用水密集度降低、用電密集度降低與碳排放密集度降低與財務績效具有顯著正向關係，此結果肯定當企業提高用水、電與碳排放的使用效率，確實有助於公司績效。但就耗用（排放）量而言，用水量降低、用電量降低與碳排放量降低與公司財務績效具有負向關係，此結果意味著，若降低用水量、用電量、碳排放量恐不利於公司財務績效，深究其緣由，可能是因產能降低、規模縮減、耗用浪費等各種原因所致，雖真實反映台灣企業現階段情況，也凸顯對於水電資源與碳排放管理政策及其成效仍有待改善之處。 本研究異於之前文獻，另一重要貢獻在於提供企業節能減碳適用之環境管理機制(ISO14001, ISO14064, ISO50001)，可強化節能減碳（使用效率）與公司財務績效之正向關係、及降低水電（用量）與財務績效的負向關係之解決途徑，故採用綠色環境管理策略確實有助於改善公司節能減碳績效與財務績效之關係。 追求永續經營是企業永遠不變的目標，企業節能減碳不應僅是順應國際潮流，基於台灣高耗能、高碳排放環境，若節能減碳可提升公司績效，對於企業未來營運應深具意義。本研究結果有助於國內企業管理當局了解藉由適當環境績效可提昇公司績效、及綠色環境管理策略所扮演的角色，進而改進經營策略與佈局；亦提供政府相關單位未來制訂我國產業因應溫室氣體排放及水電能源管理政策法規之參考。
