In the modern era societies adopt further restrictions imposed via climate or global changes and are engaged in a dynamic innovative set of dealings. The environment site is inhabited by numerous artists, who perform in a synergic manner by placing emphasis on and implementation of actual sustainable development. In this perspective, we value environmental resource-conservation efforts (ERCE) of all actors, populations, mass media and specialists. This paper aims to analyze how different energy firms accomplished sustainable development through environmental resource-conservation efforts. In this study we discover that pollution reduction is directly linked with both variables and also plays a mediating role. A cross-sectional data collection technique was used. For testing study hypotheses, we selected energy firms. Results showed that sustainable development of energy firms are forecasted by environmental resource-conservation efforts. The findings confirmed that ERCE are directly linked to pollution reduction, and pollution reduction is positively linked to sustainable development. The results also highlight how pollution reduction mediates between ERCE and sustainable development links. Energy firms play critical roles in pollution reduction. Current research contributes to prior literature knowledge through offering a sustainable development model by mutual influence of ERCE and pollution reduction. Accordingly, this study might be regarded as an encouragement for action and an authentic message for professionals in the energy firms to increase their sustainable development and give attention to their efforts on the optimal use of resources. This study can provide several critical practical policies and suggestions to management of energy firms for raising their sustainable development. Our research provides major implications through focusing on the role of ERCE and pollution reduction strategies and activities to enhance sustainable development of energy firms in a circular economy. A circular economy acts as a solution framework that helps in tackling global changes such as loss of biodiversity, pollution, climate challenges and recycling of waste. This study expands the prior literature knowledge through giving an empirical model for energy firms.
