碳排放夹点分析（CEPA）是传统的热和质量夹点分析在宏观尺度（即经济范围）上的排放目标和规划领域的最新扩展。本文提出了一个扩展到目前的方法，占需求增加和碳夹点分析的新西兰电力行业，同时说明了一些问题，实现有意义的减排。目前可再生能源发电所占的比例很大（2007年为67%），这使得广泛减少发电的碳排放变得复杂。预计可再生能源发电的最大增长将来自地热发电，其次是风能和水力发电。除了大量新的风力发电外，还需要将地热发电能力增加四倍，以将排放量减少到1990年左右的水平，并满足预计的需求。新西兰地热发电的预期扩大引起了地热田温室气体排放的问题。不同区域之间的排放因子可以相差近两个数量级，使得对总排放量的预测具有高度的场地特异性。
Carbon Emissions Pinch Analysis (CEPA) is a recent extension of traditional thermal and mass pinch analysis to the area of emissions targeting and planning on a macro-scale (i.e. economy wide). This paper presents an extension to the current methodology that accounts for increased demand and a carbon pinch analysis of the New Zealand electricity industry while illustrating some of the issues with realising meaningful emissions reductions. The current large proportion of renewable generation (67% in 2007) complicates extensive reduction of carbon emissions from electricity generation. The largest growth in renewable generation is expected to come from geothermal generation followed by wind and hydro. A four fold increase in geothermal generation capacity is needed in addition to large amounts of new wind generation to reduce emissions to around 1990 levels and also meet projected demand. The expected expansion of geothermal generation in New Zealand raises issues of GHG emissions from the geothermal fields. The emissions factors between fields can vary by almost two orders of magnitude making predictions of total emissions highly site specific.
