地方溫室氣體盤查系統

Abstract

雖然國內外已有不少地方完成溫室氣體盤查，但由於地方特性之差異，故其盤查方法不見得適用於其他地方。加上目前所發展的地方溫室氣體盤查分析工具有地域性的使用限制。本研究因而發展一套較通用且能累積各地方盤查特性資料的地方溫室氣體盤查系統，以協助地方依其特性進行溫室氣體盤查。 本研究所建立的地方溫室氣體盤查系統主要分為盤查資料庫、盤查導引及盤查資料分析三大子系統。盤查資料庫主要為提供儲存各種盤查部門、項目、排放係數及地方盤查相關資訊供地方盤查時參考使用，以解決地方進行盤查時，常遭遇盤查部門、項目及排放係數等資訊無從參考的問題。盤查導引子系統的主要功能為協助地方輸入或選擇盤查部門、項目、活動強度及排放係數，亦可由資料庫子系統取得其他地方盤查部門、項目及排放係數供參考使用，以增進盤查的效率。且可彈性依地方特性建立新的盤查部門、項目及排放係數，並儲存於資料庫子系統中供其他地方參考使用，且建立計算方法分類及選用法則協助地方選用適當之排放量計算方法。盤查資料分析子系統主要用以統計、查詢及比較各地方溫室氣體排放盤查結果。藉由盤查結果之統計並與各地方盤查結果進行比較，有助於地方互相學習及了解減量改善的方向。此外，為了使所發展的系統更具實用性，本研究採用微軟的 Excel©及VBA語言作為系統的發展工具。 目前，該系統已建立多語言版的功能，可採用中文或英文進行盤查。本研究亦已收集國內外數個地方的盤查資訊，並將其相關資訊匯入系統中，且以尚未進行盤查的新竹巿為案例示範應用及討論系統的實用性。

Currently, although many regions have established their greenhouse gas (GHG) inventories, the methods they used may not be applicable for other regions. Similarly, softwares developed for regions in a specific country may not be applicable for other countries either. This study was thus initiated to develop a GHG inventory system to assist local regions in establishing GHG inventories. The developed system consists of three major sub-systems: GHG inventory database, GHG inventory guidance, and GHG inventory data analysis. The database stores information for inventory sectors, inventory items, emission factors, and other related information that can help a region to start a new GHG inventory survey with enough sample or reference information. The GHG guidance sub-system is designed to assist a region in setting up or selecting appropriate inventory sectors, items under each sector, activity data, and emission factors. The sub-system also allows the user to create new sectors, items, and emission factors if no appropriate information can be found from the database. Emission factors stored in the database are classified into several different categories to facilitate the selection of an appropriate factor for an inventory item or activity. The data analysis sub-system provides functions to implement inventory data statistical analyses, including comparison for inventory data from different regions. Microsoft Excel© and VBA are the tools used to develop the system for providing an easy-to-learn and friendly interface. To increase its flexibility, both Chinese and English editions of the system have been made available. Inventory data from several different cities were collected and saved into the developed database. A case study for establishing the GHG inventory for Hsinchu City was implemented to demonstrate the applicability of the system.
