The process quantifies the total greenhouse gas emissions caused by an activity, product, organization, or individual. It involves assessing emissions from all stages of the life cycle, from raw material extraction through production, distribution, use, and end-of-life disposal. For instance, an assessment might determine the total emissions associated with manufacturing a single pair of jeans, including the cotton farming, dyeing, transportation, and eventual disposal of the garment.
Understanding the scope of emissions enables informed decision-making to mitigate environmental impact. Accurate measurement allows entities to identify emission hotspots, track progress towards reduction targets, and compare the environmental performance of different products or activities. Furthermore, it allows demonstration of environmental responsibility, potentially enhancing brand reputation and attracting environmentally conscious consumers and investors. Its roots lie in the growing awareness of anthropogenic climate change and the need for standardized methods to measure and manage its contributing factors.
