At the heart of our Company and our approach to sustainability lies our home-grown SPEED Value System, which has consistently guided our decisions and actions across five interlinked areas — Safety, Prosperity, Employees, Environment and Community Development. Deeply ingrained in our corporate culture, SPEED led us to further sustainability achievements in 2023.”

KEY SUSTAINABILITY HIGHLIGHTS

Strong Results in Emissions Reduction Plan

• Through GeoPark efforts, emissions intensity fell to 10.6 kg CO2e/boe in 2023, 18% lower than 2022 and 26% less than the baseline set in the GHG emissions reduction plan announced in November 2021¹
• Carbon intensity on the core Llanos 34 Block (GeoPark operated, 45% WI) fell 28% to 7 kg CO2e/boe in 2023, a 42% reduction from the already low baseline of 12.1 kg CO2e/boe
