Climate change is one of the major worldwide environmental concerns. It is especially the case in many developed countries, where the greenhouse gas emissions responsible for this change are mainly concentrated. For the first time, the Kyoto Protocol includes an international agreement for the reduction of the net emissions of these gases. To fulfil this agreement measures designed to reduce or limit current emissions have to be brought into force. Consequently, fears have arisen about possible consequences on competitiveness and future development of manufacturing activities and the need for support mechanisms for the affected sectors is obvious. In this paper, we carry out a study of the emissions of gases responsible for climate change in Asturias (Spain), a region with an important economic presence of sectors with intensive emissions of CO(2), the chief greenhouse gas. To be precise, in the first place, the volumes of direct emissions of the said gases in 1995 were calculated, showing that the sectors most affected by the Kyoto Protocol in Asturias are iron and steel and electricity production. Secondly, input-output analysis was applied to determine the direct and indirect emissions and the direct, indirect and induced emissions of the different production sectors, respectively. The results derived from the direct and indirect emissions analysis and their comparison with the results of the former allow us to reach some conclusions and environmental policy implications.
气候变化是全球主要的环境问题之一。在许多发达国家尤其如此,造成这种变化的温室气体排放主要集中在这些国家。《京都议定书》首次纳入了一项减少这些气体净排放的国际协议。为履行该协议,必须实施旨在减少或限制当前排放的措施。因此,人们担心这可能对制造业活动的竞争力和未来发展产生影响,而且受影响行业显然需要支持机制。在本文中,我们对西班牙阿斯图里亚斯地区造成气候变化的气体排放进行了研究,该地区某些行业在经济中占重要地位,且二氧化碳(主要温室气体)排放密集。具体而言,首先计算了1995年上述气体的直接排放量,结果表明阿斯图里亚斯受《京都议定书》影响最大的行业是钢铁和电力生产。其次,运用投入产出分析分别确定不同生产部门的直接和间接排放以及直接、间接和诱导排放。直接和间接排放分析得出的结果以及与前者结果的比较,使我们能够得出一些结论和环境政策含义。
