Abstract

There are two main ways to reduce anthropogenic GHG emissions: energy efficiency improvement and in- crease usage of renewable energy sources. Taking these two main ways into account, it is possible to analyze the main drivers of GHG emissions in the country and to make forecast of future GHG emissions based on historical trends. The Visegrad group (V4) countries, including Poland, Hungary, Slovakia, and Czech Republic were selected to provide comparative assessment of their GHG emission drivers and to evaluate effects of climate change mitigation policies in energy sector on GHG emission trends. The Kaya identity approach was applied allowing to perform simple multiplication. Kaya identity equation substitutes the factors with well- established and measurable quantities, which leave little space for ambiguity. The multiplying population size by GDP per capita, energy intensity, and carbon intensity of energy allows to get total GHG emissions in the country and define its energy efficiency or use of renewables are the main drivers of GHG emissions, including the effect of economic growth expressed by GDP per capita.

维谢格拉德国家温室气体排放主要驱动因素分析:Kaya同一性方法

减少人为温室气体排放的主要途径有两种:提高能源效率和增加可再生能源的使用。考虑到这两种主要方式，就有可能分析该国温室气体排放的主要驱动因素，并根据历史趋势对未来温室气体排放进行预测。选择维谢格拉德集团(V4)国家，包括波兰、匈牙利、斯洛伐克和捷克共和国，对其温室气体排放驱动因素进行比较评估，并评估能源部门减缓气候变化政策对温室气体排放趋势的影响。应用Kaya恒等式方法可以执行简单的乘法。卡雅恒等式用已确定的可测量的量来代替因子，这样就不会留下歧义的空间。将人口规模乘以人均GDP、能源强度和能源碳强度，可以得到该国的温室气体排放总量，并确定其能源效率或可再生能源的使用是温室气体排放的主要驱动因素，包括人均GDP表示的经济增长的影响。

期刊介绍： The mission of the Contemporary Economics is to publish advanced theoretical and empirical research in economics, finance, accounting and management with the noticeable contribution and impact to the development of those disciplines and preferably with practice relevancies. All entirety of methods is desirable, including a falsification of conventional understanding, theory building through inductive or qualitative research, first empirical testing of a theory, meta-analysis with theoretical implications, constructive replication that clarifies the boundaries or range of a theory for theoretical research as well as qualitative, quantitative, field, laboratory, meta-analytic, and combination for an empirical research. This clear priority for comprehensive manuscripts containing a methodology-based theoretical and empirical research with implications and recommendations for policymaking does not exclude manuscripts entirely focused on theory or methodology. Manuscripts that raise significant, actual topics of international relevance will be highly appreciated. The interdisciplinary approach including – besides economic, financial, accounting or managerial –also other aspects, is welcomed.
