What is 'Greenhouse Gas Protocol'?
Explanation
The Greenhouse Gas Protocol is an international accounting tool developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD) to provide standardized frameworks for measuring and managing emissions. It is often confused with inter-governmental treaties like the Kyoto Protocol or Paris Agreement (Option C), but it is actually a voluntary partnership rather than a legally binding UN-led mandate. The core concept being tested is the identification of global environmental governance frameworks and the distinction between non-governmental standards and formal international law.
