Enterprise Carbon Accounting (ECA)/ Corporate Carbon Footprint aims to be a rapid and cost effective process for businesses to collect, summarise, and report enterprise and supply chain GHG inventories. ECA leverages financial accounting principles, whilst utilising a hybrid of input-output LCA (Life Cycle Analysis)and process methodologies as appropriate. The evolution to ECA is necessary to address the urgent need for a more comprehensive and scalable approach to carbon accounting. While an emerging area, a number of new companies offer ECA solutions.〔Groom Energy, "Enterprise Carbon Accounting: An Analysis of Organizational-Level Greenhouse Gas (GHG) Reporting and a Review of Emerging GHG Software Products", Dec, 2008 http://www.groomresearch.com〕 ECA is a critical part of broader Enterprise Sustainability Accounting. ==Characteristics of ECA== To be successful, an Enterprise Carbon Accounting system should have the following characteristics: Comprehensive: Incorporates Scope 1,2 and 3 emissions Periodic: Enables updates at regular intervals and comparisons across reporting periods Auditable: Traces transactions and enables independent reviews for compliance Flexible: Incorporates data from multiple approaches to life cycle analysis Standards-Based: Accommodates existing generally accepted standards and emerging standards Scalable: Accommodates growing volume and complexity of business operations Efficient: Delivers data in the timeframe required for decision making Enterprises that realize reduced emissions and energy consumption utilize systems with the following capabilities: * Real-time historical energy data that is easily accessible * Role-based visibility into plant emissions data * Provides executives with real-time visibility into emissions data * Ability to benchmark emissions levels with goals and industry standards 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Enterprise carbon accounting」の詳細全文を読む スポンサード リンク
