EcoSolutions Inc. is undertaking a GHG emission reduction project by constructing a wind farm to replace a coal-fired power plant. As the lead auditor for the ISO 14064-2:2019 verification, you are tasked with assessing the project\'s compliance. The project proponents claim significant emission reductions based on a baseline scenario that assumes the coal-fired plant would have continued operating at full capacity for the project\'s duration. The project\'s monitoring plan relies heavily on self-reported data from the wind farm operators, with limited independent verification. During your initial assessment, you discover that the regional electricity grid already had a surplus of renewable energy capacity, and the coal-fired plant was frequently operating below full capacity due to decreased demand. Additionally, there is evidence suggesting that some industrial consumers have relocated to areas with cheaper electricity, potentially offsetting some of the emission reductions achieved by the wind farm. Considering these factors, what should be your primary focus during the audit to ensure the credibility and accuracy of the reported GHG emission reductions?
