< Previous26 2024 SUSTAINABILITY REPORT EMISSIONS REDUCTION A Comprehensive Emissions Reduction Strategy GTE has significantly reduced its emissions intensity over the past 6 years. At the core of these efforts is its Energy Transition, Emissions Reduction, and Climate Adaptability strategy—a cross-functional framework that guides the Company’s greenhouse gas (GHG) emissions management. The plan aligns with internationally recognized standards and institutions, including Colombian national technical GHG reporting standard NTC ISO-14064-1:2020, the World Resources Institute (WRI), the World Business Council for Sustainable Development (WBCSD), and Task Force on Climate-Related Financial Disclosures (TCFD). GTE’s emissions management strategy is structured around two areas: GREENHOUSE GAS MITIGATION measurement, Analysis, and Reporting of direct (Scope 1) and indirect (Scope 2) emissions. Emissions data is externally verified under ISO 14064 and presented in an annual Greenhouse Gas Emissions Report. Emissions Reduction – GTE has developed a portfolio of cost-effective projects including: • Energy efficiency improvements • Zero routine flaring and gas-to-power (G2P) initiatives • methane management and electrification programs • Nature-based solutions (NBS), including reforestation efforts CLIMATE ADAPTABILITY GTE manages physical and transitional climate risks, implementing a variety of measures to safeguard operations and support adaptation. Key initiatives include: • Risk management planning • Social investment programs • Nature-based solutions • Institutional partnerships • Water risk management programs STEWARDING THE ENVIRONMENT HEALTH AND SAFETY RESPECTING HUMAN RIGHTS INVESTING IN COMMUNITIES ENGAGING OUR NEIGHBOURS RESPONSIBLE GOVERNANCE INTRODUCTION ECONOMIC DEVELOPMENTSTEWARDINGTHE ENVIRONmENT27 77% DECREASE IN FLARING GHG EMISSIONS SINCE 2019 (ACROSS ALL SOUTH AMERICAN ASSETS) OF POWER COMES FROM THE GRID 9% OF ENERGY USED ACROSS ALL SOUTH AMERICAN ASSETS GENERATED BY G2P 72% COMES FROM CRUDE OR DIESEL 19% (Note: Ecuador G2P began in November 2024) 856,414 Mcft FLARED GAS 2,493,810 Mcft G2P GAS PREVENTING FUGITIVE EMISSIONS As part of its commitment to operational integrity and environmental responsibility, GTE conducted a fugitive emissions survey in Colombia in 2024, identifying and repairing several small leaks. In Ecuador, the Company is developing a greenfield project with infrastructure designed early on to meet the highest environmental and operational standards. Advanced detection technologies in Canada are implemented to monitor and reduce fugitive emissions from its assets. Looking ahead, the Company will continue upgrading infrastructure, monitoring systems, and implementing best practices to further reduce emissions and improve reliability. CUTTING EMISSIONS IN CANADA In GTE’s Western Canada operations, 519 high-bleed gas pneumatic pumps have been replaced with solar-powered alternatives, reducing methane venting at 255 locations. Aircraft-mounted LiDAR-based leak detection systems have also helped reduce fugitive methane emissions by over 50% since 2023, while electrification efforts at the Simonette site and other infrastructure optimizations have further lowered emissions and costs. These and other ongoing equipment upgrades, including replacing generators and compressors with solar-powered and electric alternatives, have reduced emissions by over 17,000 tCO₂e annually. MAXIMIZING ENERGY EFFICIENCY THROUGH GAS-TO-POWER INITIATIVES GTE’s Gas-to-Power (G2P) initiatives have significantly reduced emissions and optimized fuel use. By improving natural gas recovery from wells and replacing purchased diesel with natural gas, even in smaller fields, the Company has lowered Scope 1 and 2 emissions, reduced reliance on truck-transported diesel, and improved operational efficiency. In Colombia, utilizing produced gas for power generation has minimized flaring to less than 19% of total gas production, with gas providing over 72% of energy used by South American operations. In Ecuador, G2P has already been implemented in some facilities, with the replacement of diesel generators and installation of more efficient artificial lift pumps. Further modifications are expected soon in the new facilities, as GTE continues to explore new ways to optimize its fuel use, reduce flaring, and further shrink its carbon footprint. SOUTH AMERICA POWER AND EMISSIONS HIGHLIGHTS282024 SUSTAINABILITY REPORT WATER Protecting Water Resources Gran Tierra Energy is committed to protecting freshwater resources in Colombia and Ecuador, as they are vital to local communities and ecosystems. The Company employs rigorous water protection measures, which often exceed regulatory standards, to prevent impacts on groundwater and aquifers. Key actions include isolating drilling operations with proven technology, continuously monitoring surface and groundwater quality, and regularly testing over 600 monitoring wells in Colombia and Ecuador. In 2024 alone, more than 1,300 water samples were analyzed in South America. Independent results confirm that GTE has maintained groundwater integrity throughout its operations. WATER MANAGEMENT GTE is committed to efficient water management and progressing towards water neutrality. In 2024, the Company began measuring its water footprint in line with ISO 14046 and Water Footprint Network (WFN) standards. In line with its goal of zero surface water use and disposal, GTE continues to reduce water consumption per barrel while increasing production, with the long-term objective of achieving 100% closed-cycle water use. GTE has led water neutrality efforts in Colombia through its role in advancing regulatory reform that permits using water produced from non-oil-producing zones in its reservoirs for enhanced oil recovery, reducing reliance on shared water sources. Based on World Wildlife Fund’s Water Risk Filter methodology, GTE’s comprehensive water risk management plan evaluates physical, regulatory, and reputational risks associated with water use. Additionally, water monitoring is continuous with surface and groundwater sites located according to environmental regulations and project baselines.

Colombian regulations require extractive companies to allocate 1% of their project development budget to environmental protection. Rather than simply acquiring land for reforestation, GTE often integrates these efforts with long-term sustainability initiatives. In less than a year of operation, the Acordionero Forestry Centre has already conserved 185 hectares and planted 10,992 trees, now playing a key role in protecting water resources in the Lebrija River sub-basin, which feeds into the Magdalena River. Meanwhile, the Costayaco Forestry Centre in villagarzón has conserved 334.5 hectares and planted 89,652 trees, enhancing ecosystem connectivity between the Andes and the Amazon. Colombia’s National Environmental Licensing Authority (ANLA) has recognized its forestry centres as effective strategies for reforestation and biodiversity conservation.322024 SUSTAINABILITY REPORT 375 BEEKEEPERS TRAINED 6,000 HIVES MAINTAINED NATURAMAZONAS Leading Conservation in the Colombian Amazon NaturAmazonas, Gran Tierra Energy’s flagship conservation program with Conservation International, has grown into a powerful alliance of public and private institutions tackling the root causes of deforestation. NaturAmazonas has been at the forefront of Colombian conservation and reforestation efforts for seven years. With an $18 million investment, GTE has created a model for protecting the Colombian Amazon's land, water, air, and biodiversity. In partnership with Conservation International, the Colombian Ministry of Environment and Sustainable Development, and Corpoamazonia, the program has restored ecosystems, fortified biodiversity and advanced sustainable agriculture. Equally important, NaturAmazonas strengthens the connection between people and nature, supporting lasting impact in one of the world’s most biodiverse regions. NaturAmazonas has driven critical advancements in ecological restoration, significant biodiversity research publications, and land management, offering valuable insights for future sustainability programs. Some of the initiative’s recent successes include: LOCAL CACAO FARMERS SECURE MAJOR EXPORT Nearly 700 participating families in Caquetá, Cauca, and Putumayo exported over ten tons of deforestation-free organic cocoa to France via one of the largest buyers of organic cocoa worldwide. LEVERAGING BEEKEEPING FOR CONSERVATION NaturAmazonas’ leadership in meliponiculture (stingless beekeeping) has been vital for biodiversity conservation, enhancing pollination in the Amazon. The program has trained 375 beekeepers, who maintain Colombia’s largest stingless bee population—6,000 hives pollinating 24,000 hectares of native forests and plantations, with an annual honey production capacity of over one ton. NaturAmazonas also leads national efforts to regulate meliponiculture and, in collaboration with allied entities, is a pioneer in studying and characterizing Amazonian honeys. Additionally, the program has opened new international markets for local producers of high-value medicinal honey. DRIVING COLLABORATION IN BIODIVERSITY RESEARCH AND PUBLICATIONS NaturAmazonas has partnered with the Wildlife Conservation Society, University of Kansas, and National University of Colombia to characterize Amazonian honey and identify native bee species. These efforts have also led to the publication of two significant biodiversity resources: the Butterfly Guide and the Guide to Plants of Cultural Interest for the Zio Bain People, both part of Conservation International’s Tropical Field Guide series.

Aquaponics is a self-sustaining system where fish waste provides nutrients for plants, and the plants help filter and purify the water in return. This reduces water consumption by 80% compared to traditional farming. The system also eliminates agrochemicals, making it a cleaner, more efficient way to grow food, especially for families with limited land. The Acordionero Forestry Centre also includes a meliponiculture initiative that plays a key role in biodiversity conservation by protecting and reproducing native stingless bees—essential pollinators that support the health and regeneration of local ecosystems. These bees assist in the pollination of both native forests and the existing plants in the AFC, helping sustain biodiversity and agricultural productivity. Through the Acordionero Forestry Centre, Gran Tierra Energy continues to support community-driven initiatives to strengthen Colombia’s ecosystems and support local families. This initiative isn’t just about growing food—it’s about transforming quality of life. Once we show people that it works, they’ll be eager to join—whether they are interested in the environment, economics, or both. Gretta Lopez Biologist & Environmental Professional WORKING WITH INDUSTRY PARTNERS FOR BIODIVERSITY IN COLOMBIA GTE plays a role in strengthening industry-wide sustainability efforts through participation in the trade organization National Business Association of Colombia’s (ANDI) biodiversity and sustainability initiatives, participating in multilateral partnerships that promote conservation and advance scientific knowledge in the country. PRESERVING THE CULTURAL HERITAGE OF THE AMAZON The Suruma museum, known as "A museum to Think About Putumayo," has been an important cultural institution in Colombia’s Amazon region since it opened four years ago. In 2024, it welcomed over 11,000 visitors, and a traveling exhibit was also on display in various locations around the country during that time. As the first archaeological museum in Colombia’s Amazon region, Suruma is vital for preserving historical artifacts, promoting cultural awareness, and stimulating tourism. It also deepens awareness of the region’s rich history and commitment to environmental preservation.
