As concerns about climate change and carbon emissions continue to rise, many companies and organizations are eager to assess their “carbon footprint” to understand their impact on this global challenge. In the realm of oil production, the environmental consequences can be quite serious, leading to issues like air pollution and heightened global warming potential (GWP) due to increased greenhouse gases (GHG). This study investigates the greenhouse gas (GHG) emissions associated with crude oil and natural gas production at Khalda Petroleum’s sites in Egypt’s western desert. Activities contributing to emissions were categorized by operational boundaries—Scopes 1, 2, and 3—and their carbon footprints were quantified. Key emission sources were identified, with gas flaring and diesel consumption emerging as major contributors, while water supply and refrigerants had minimal impact. Linear relationships revealed strong positive correlations between fuel use, flaring, and venting activities, and GHG emissions, with R2 values close to 1. Polynomial relationships highlighted the influence of device efficiency on emissions, suggesting that optimizing combustion and refrigerant systems is critical for reduction. Recommendations include adopting advanced flaring technologies, switching to cleaner fuels, enhancing equipment efficiency, and integrating renewable energy sources. These strategies aim to minimize emissions while maintaining operational efficiency, aligning Khalda Petroleum with global sustainability standards. Continuous monitoring, employee training, and stakeholder collaboration are emphasized as essential components for long-term success.
