What is the primary purpose of the Greenhouse Gas (GHG) Protocol?

The primary purpose of the Greenhouse Gas (GHG) Protocol is to provide a global standard for measuring and managing greenhouse gas emissions. This framework is essential for organizations and governments as it establishes comprehensive guidelines for accounting and reporting emissions. By standardizing these practices, the GHG Protocol enables entities to consistently quantify and disclose their GHG emissions in a way that can be compared across different sectors and regions. This transparency and consistency are crucial for tracking progress towards climate goals, assessing corporate sustainability performance, and facilitating regulatory compliance.

The other options, while related to sustainability and policy, do not encompass the specific aim of the GHG Protocol. Promoting economic output and prosperity, regulating sustainability claims, and evaluating national happiness metrics refer to broader themes that address different aspects of societal well-being and economic development, rather than focusing directly on the measurement and management of greenhouse gas emissions.
