CostCo ESG Reporting Intern

I learned that Costco utilizes Microsoft Sustainability Manager (MSM) for emissions calculations, which relies on data input from various employees across the organization. So, while I wasn't directly responsible for calculating emissions, I did get to play a part in analyzing and validating the data generated by MSM. This involved reviewing data for any variances that exceeded an acceptable threshold, which I would identify by calculating the percent change period over period. I would then analyze the cause of those discrepancies. For example, if a new warehouse was built or data hadn't been fully updated, that could cause our emissions numbers to be flagged as having changed more than would typically be expected.
