Environment

TGS manages environmental risk through project planning, field controls and operational monitoring. Before work begins, we assess potential environmental impacts using permitting requirements, environmental impact assessments, site surveys, stakeholder input and project-specific risk reviews. This helps identify potential impacts on sensitive habitats, protected species, fisheries, local communities and other environmental receptors.

Controls are built into project plans, environmental plans, crew procedures and contractor requirements. For marine operations, mitigation may include protected species observers, passive acoustic monitoring, soft starts, operational delays, buffer zones, spill prevention measures and waste controls. For onshore operations, controls may include access planning, route selection, timing restrictions, equipment cleaning, dust and noise controls, spill prevention and site restoration.

During operations, crews follow permit requirements, monitor environmental conditions and report observations, incidents and improvement actions through TGS' HSEQ processes. Lessons learned from projects, audits, inspections and contractor reviews are used to improve future planning and strengthen environmental controls.

TGS measures emissions, spills, waste and other environmental indicators to guide action and report progress. Our Climate Transition Action Plan sets targets to reduce absolute Scope 1, Scope 2 and relevant Scope 3 greenhouse gas emissions by 30% by 2030 and by more than 90% by 2050, using 2019 as the baseline year.

TGS' Climate Transition Action Plan focuses on practical emissions reductions across operations and the value chain. Because marine vessel activity is a major source of emissions, priority actions include improving vessel efficiency, using performance monitoring, applying weather routing, assessing lower-carbon technologies and supporting sector work on carbon intensity metrics.
