Conclusions
10.00 101.00%
The results show that 2019 GHG emissions, within the reporting boundary, totalled 684,518 tonnes of CO2 equivalent (CO2e). Gran Tierra Energy continues to take actions to lower GHG emissions by utilizing excess natural gas from our operations to generate power and maintain reservoir pressure instead of flaring it. Gran Tierra’s major capital investments in voluntarily “Gas-to-Power projects” continue to be an important part of our efforts in reducing flaring. Gran Tierra has also supported carbon dioxide sequestration projects, like the Costayaco Forestry Center and NaturAmazonas.
2019 Report Recommendations
• Continue to record operational changes (addition and/or removal of equipment) to accurately track the changes in GHG emissions.
• Recording and documenting monthly flare volumes improves the accuracy of emissions measured. GTE should continue these important efforts and look for opportunities to improve going forward.
• For combustion equipment, implement a flowmeter to detect and measure any leaks, while also monitoring fuel consumption.
• For refined estimates of tank venting emissions, consider creating a comprehensive inventory of the tanks’ products and track the products in each facility.
• Establish a transparent data management system for operational and fuel data collection.
