چکیده

نیروگاه‌ها و پالایشگاه‌ها، با مصرف سوخت فسیلی موجب انتشار دی‌اکسیدکربن در محیط می‌شوند و هر دو از صنایع آلاینده به‌شمار می‌آیند. در این پژوهش ارتباط بین مصرف انرژی، ارزش افزوده و انتشار دی‌اکسید کربن در نیروگاه‌ها و پالایشگاه‌ها در قالب منحنی زیست‌محیطی کوزنتس بررسی شده است. نتایج حاکی از آن است که شکل زنگوله‌ای منحنی زیست‌محیطی برای نیروگاه‌ها و همین طور پالایشگاه‌های مورد بررسی، طی دوره ۱۳۹۱- ۱۳۷۷برقرار نیست. نتایج به‌دست‌آمده نشان‌دهنده یک رابطه N شکل برای نیروگاه‌ها و رابطه‌ایU ‌شکل برای پالایشگاه‌ها است؛ بدین معنا که در نیروگاه‌ها، روند انتشار CO2 طی رشد اقتصادی افزایشی است و در پالایشگاه‌ها این روند در ابتدا کاهشی و سپس افزایشی شده است. همچنین در بخش‌های مورد بررسی، مصرف انرژی با انتشار  CO2دارای یک رابطه مثبت معنادار است.

چکیده [English]

Power plants and refineries due to their process and consumption of fossil fuels release carbon dioxide into the environment and, as a consequence, both industries are polluting. In this study, the link between energy consumption and carbon dioxide emissions at power plants and refineries is surveyed as added value in the form of Environmental Kuznets Curve. Results indicate that the bell-shaped curve for environmental studies of power plants as well as refineries over the period 1997-8 to 2011-12 is established. Results have shown a U-shaped relationship for power plants and N-shaped interfaces for the refinery. This means that, during the economic growth in power plants, CO2 emissions are increasing and, in refineries, that process has first decreased and then increased. Also, as a part of this study, energy consumption had a positive significant correlation with CO2 emissions.
