"Upstream" refers to the process of moving resources or information toward the source or origin. In a business context, it often involves activities related to the initial stages of production, such as sourcing raw materials or managing supply chains. This phase is crucial for ensuring that the necessary inputs are available for manufacturing or service delivery. In environmental discussions, "upstream" can also describe actions taken to prevent pollution or resource depletion before they occur. For example, implementing sustainable practices in agriculture or manufacturing can help reduce negative impacts on ecosystems, promoting a healthier environment for future generations.
