2020 Study of Greenhouse Gas Emissions
In 2021, Gran Tierra Energy (GTE) retained CAIA Ingenieria, a respected Colombian expert in the field of air quality, to create a voluntary assessment of its greenhouse gas (GHG) emissions. This assessment involved collecting, analyzing and quantifying 2020 air emissions data from GTE’s operations.
“For the first time in 2021, GTE has calculated and reported additional emissions data from Direct Operations (Scope 1) and Indirect Operations from external power sources (Scope 2). In doing so, GTE continues to improve its transparency in this area. The company also continues to take action in order to deliver meaningful emission reduction strategies—to protect the environment while developing Colombia’s economy.”

Study Methodology
The most prevalent GHGs emitted from oil and natural gas industry operations are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Collecting this data is important because many scientists believe these gases contribute to global climate change. This information will allow GTE, its local and global stakeholders and the public to assess the company’s emission reduction efforts over time.
The assessment was conducted according to guidelines and standards adopted by the following organizations: International Petroleum Industry Environmental Conservation Association (IPIECA), International Association of Oil and Gas Producers (IOGP), American Petroleum Industry (API), U.S. Environmental Protection Agency (EPA), Canadian Association of Petroleum Producers (CAPP) and Intergovernmental Panel on Climate Change (IPCC).
Reporting Principles & Scope
CAIA Ingeneiria prepared the report in adherence with the following principles of the IPIECA:
which are all currently in Colombia:
§ The Putumayo process facilities, well pads and camps
§ The Middle Magdalena Valley process facilities, well pads and camps § The Bogota Office
Reporting Period
The reporting period is defined as January 1st through December 31st, 2020.
Reporting and Understanding GHG Emissions:
Gases have different heat absorption and retention capacities. The Global Warming Potential (GWP) is a relative measure of how much heat potential a greenhouse gas absorbs and retains in the atmosphere. The GWP is used to compare global warming impacts of various gases. The higher the GWP, the more energy the gas absorbs per unit weight, thereby having a greater global warming impact. The GWP is a coefficient and is multiplied by the unit weight of gas type.
