چکیده

با وجود افزایش مصرف انرژی در سطح جهانی، بسیاری از کشورها به دنبال ایجاد یک موازنه بین مصرف انرژی و اثرات زیست محیطی ناشی از آن هستند. برای این منظور مطالعات زیادی جهت محاسبه و شناخت راه‌های کاهش انتشار کربن و عوامل موثر بر آن ارائه شده است. در این پژوهش با استفاده از یک تحلیل داده- ستانده، میزان انتشار کربن در بخش‌های مختلف مورد بررسی قرار گرفته و با محاسبه شدت ساختاری و شدت مصرف داخلی، اثر آن بر شدت کل بررسی شده است. برای برآورد الگوی تحقیق از جدول داده- ستانده سال‌های 2011 و 2014 اقتصاد ایران استفاده شده است. نتایج نشان می‌دهد، انتشار کربن در بخش‌های مختلف متفاوت و لذا شدت انتشار کربن آن‌ها نیز متفاوت است. به طور کلی شدت انتشار کربن در سال 2014 نسبت به سال 2011 افزایش یافته است، شدت انتشار کربن در بخش کشاورزی بیشترین افزایش را نشان می‌دهد. همچنین اثر ساختاری و تقاضای نهایی داخلی روی اثر شدت سبب افزایش در شدت جمع‌سازی شده تجسم‌یافته انرژی و آلودگی کل ملی شده است. به عبارت دیگر اثر ساختاری و تقاضای نهایی سبب تقویت شدت انتشار کربن می‌شود.

چکیده [English]

Since the energy consumption has increased globally, many countries are searching to conduct a procedure for balancing between the energy consumption and its environmental impact. Therefore, there has been plenty of research to discover new strategies for decreasing carbon emission and highlighting the influential factors. This study has analyzed the carbon emission measures in several different sectors using the input-output approach. Also, the study has measured the effect of carbon emission on the total intensity by calculating the structural intensity and domestic energy consumption. The data is extracted from social matrix of Iran`s economy in 2011 and 2014. The findings indicate that the gas emission rate differs in different sectors and as a result the emission intensity is also different. In general, the emission intensity from 2014 has increased compared to 2011 though the emission intensity in agriculture sector has surged. Also, the total national AEI has increased as a result of structural effect and final demand for it. In other words, structural effect and final demand has influenced in the surge of carbon emission.
