China is the world's largest emitter of carbon dioxide, and it is also one of the largest fluorescent lamp consuming and producing country in the world. However, there are few studies evaluating greenhouse gas (GHG) emissions of fluorescent lamps in China. This analysis compared GHG emissions of compact fluorescent lamps with linear fluorescent lamps using life cycle assessment method in China's national conditions. The GHG emissions of fluorescent lamps from their manufacture to the final disposal phase on the national level of China were also quantified. The results indicate that the use phase dominates the GHG emissions for both lamps. Linear fluorescent lamp is a better source of light compared to compact fluorescent lamp with respect to GHG emissions. The analysis found that in 2011, China generated around 710.90milliontons CO-eq associated with fluorescent lamps. The raw material production and use phases accounted for major GHG emissions. More than half of GHG emissions during the domestic production were embodied in the exported lamps in recent years. This urges the government to take necessary measures that lead to more environmental friendly production, consumption and trade patterns.
中国是世界上二氧化碳排放量最大的国家，也是世界上荧光灯消耗和生产最大的国家之一。然而，目前评估中国荧光灯温室气体（GHG）排放的研究较少。本研究采用生命周期评价方法，在中国国情下，比较了紧凑型荧光灯和直管荧光灯的温室气体排放。还定量了荧光灯从制造到最终处置阶段在国家层面上的温室气体排放。结果表明，对于这两种灯，使用阶段都占主导地位。就温室气体排放而言，线性荧光灯比紧凑型荧光灯更具光源优势。分析发现，2011 年中国生产的荧光灯产生了约 7109 万吨二氧化碳当量。原材料生产和使用阶段占主要温室气体排放量。近年来，国内生产过程中超过一半的温室气体排放体现在出口灯具中。这促使政府采取必要措施，促使生产、消费和贸易模式更加环保。
