摘要

「全球暖化」為當前全球面臨最嚴峻的考驗，更是人類文明史上前所未見對於環境、生態、經濟、社會及健康的挑戰。京都議定書於2005年2月16日正式生效，儼然已宣告碳排放管制與交易的時代已將來臨，我國雖非締約國，目前也尚無溫室氣體減量責任，但依據國際能源總署（IEA）公布2009年全球燃料燃燒二氧化碳排放量，台灣排名全球第23名，由統計數據得知台灣日後勢必承受國際間減量壓力。為了減緩家電產業供應鏈於未來可能遭遇的國際溫室氣體規範，本研究依據ISO 14064溫室效應氣體盤查規範進行盤查，統計A家電公司2010年各範疇溫室氣體的排放源及排放強度後，並進一步探討家電產業溫室氣體減量的策略。本研究案例以2010年為溫室氣體排放量之盤查基準年，其溫室氣體盤查結果為5900.40公噸CO2e，依ISO 14064定義：範疇一-直接溫室氣體排放量為1160.57噸CO2e，佔總排放量的19.67%、範疇二-能源間接排放量為4739.84公噸CO2e，佔總排放量的80.33%、範疇三-其他間接能源排放量，因資料來源收集上較不易取得，故目前以定性盤查方式為主。依據京都議定書管制的六種溫室氣體，盤查結果發現CO2的排放量為5662.82公噸CO2e，佔整體的95.97%、CH4排放量為4.75公噸CO2e，佔整體的0.08%、N2O排放量為1.72公噸CO2e，佔整體的0.03%；HFCs排放量為231.32公噸CO2e，佔整體的3.92%；因PFCs、SF6無任何溫室氣體排放量，故可予以忽略。

“Global warming” is one of the most vigorous tests that the Earth is facing, as well as a challenge to environment, ecology, economy, society and health that has never been seen in human history. Feb 16 2005, the day the Kyoto Protocol was officially in effect, marks the arrival of the era of CO2 emission control and trading. Taiwan is nut a member of this protocol, but still at the 23rd place around the world for GHG emission . The data of International Energy Agency (IEA) indicate that Taiwan will be inevitably facing the pressure from other countries around the world if proper action is not taken. To help the home appliance industrial chain avoid the potential limits of international GHG specifications, inventory checks were performed based on ISO 14064. The GHG emission source and intensity in every scope of the home appliance company A in 2010 were investigated, and a strategy for GHG reduction was devised for home appliance industries. 2010 was selected as the base year for the inventory checks of GHG emission. The results showed that the GHG emission was 5900.40 ton-CO2e. Based on the definition of ISO 14064, Scope1, the direct emission of GHG, was 1160.57 tons-CO2e, accounting for 19.67% of total emission; Scope 2, indirect emission from energy consumption, was 4739.84 tons-CO2e, accounting for 80.33% of total emission; and Scope 3, other indirect emission from energy consumption, was difficult to determine as the sources of other indirect emission were outsourced activities. As a result, the qualitative inventory check was selected for this study. For the 6 GHGs defined in the Kyoto Protocol, the inventory results indicated that CO2 emission was 5662.82 tons-CO2e, making up 95.97% of total emission, CH4 was 4.75 tons-CO2e, making up 0.08% of total emission, and N2O was 1.72 tons-CO2e, making up 0.03%. The emission of HFCs accumulated to 231.32 tons-CO2e, accounting for 3.92% of total emission. PFCs and SF6 were negligible as there was no emission of these 2 GHGs.
