2019 Study of Greenhouse Gas Emissions by SLR Consulting
In 2020, Gran Tierra Energy (GTE) for the fifth consecutive year retained SLR Consulting (previously Novus Environmental Inc.), a respected international expert in the field of air quality, to create a voluntary assessment of its greenhouse gas (GHG) emissions in Colombia. This assessment involved collecting, analyzing and quantifying 2019 air emissions data from GTE’s operations.
At Gran Tierra, it’s not enough to simply mitigate any impacts on the environment that could arise from our operations; our vision
is to create a model that not only prevents negative impacts, but also works to reverse to them. We are pleased to share our annual 2019 GHG report results, which shows the air emissions data from our operations and also the corrective actions that GTE has taken to lower emissions.
– Gary Guidry, President and CEO
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.
Study Methodology
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
SLR Consulting prepared the report in adherence with the following principles of the IPIECA:
are all currently in Colombia:
§ The Putumayo process facilities and well pads
§ The Middle Magdalena Valley process facilities and well pads
Equipment located within the physical plant boundary but not operated by GTE are
not included in the reporting boundary.
Reporting Period
The reporting period is defined as January 1st through December 31st, 2019.
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.
