Environmental Performance Management in PTTEP
For an effective implementation of environmental management and alignment with PTTEP Sustainable Development Policy and Green Practices Roadmap, PTTEP wishes to mitigate and reduce the environmental impact through the improvement of the environmental performances across all company activities. PTTEP has set the short-term and medium-term targets for the material environmental issues since 2012 and have cascaded to either corporate or asset levels for integration into their annual Key Performance Indicator (KPI)-setting process. Each environmental KPI and its environmental performance are presented in the Sustainability Report.
Greenhouse Gas Emission
To be a leading E&P company, PTTEP has committed to exploring a clean and reliable energy through an investment in natural gas and greenhouse gas reduction initiatives. In addition, the initiatives in RD&T have been developed to support greenhouse gas reduction as well. The progress of the company’s climate change management, especially the GHG reduction projects and GHG emission reduction performance, is shown in the Sustainability Report.
As methane is a major greenhouse gas contributor, PTTEP has committed to limiting methane emissions from its activities through flaring and leakage minimization. Baseline studies on methane emissions have been annually conducted at each major operating asset, from which the simple leakages shall be fixed promptly and followed-up on a regular basis to ensure the effective methane reduction. Ultimately, results from the emission studies can be used for improving the annual GHG performance.
PTTEP aims to improve energy efficiency by 5 percent from base year 2012 by 2020. In 2013-2016, PTTEP developed energy baseline studies in operating assets to assess the initial opportunities for energy efficiency improvement; conducted a study on introducing best available technologies to apply at project level including financial analysis of the feasibility; and identified indicators for energy use control.
In 2016, PTTEP widened the scope of the energy efficiency program by conducting an energy consumption baseline study to identify significant energy-consuming activities for Zawtika project in Myanmar. The study results will be used to introduce new energy efficiency initiatives in the future.
To support water resource management, PTTEP intends to reduce the volume of freshwater consumption from our operations. From the operating assets, PTTEP focused on and set a water reduction target for the S1 asset, which consumes a significant amount of freshwater. We aim to reduce our freshwater intensity at S1 asset by 5 percent in 2020 based on 2013 as the base year. In 2017, freshwater consumption of S1 project was reduced by 46,000 m3 approx. compared to 2013 base year. This achievement is from improvements to the cooling system and water circulation maintenance program to significantly reduce water loss in the production process.
PTTEP’s target is to achieve zero hazardous waste to landfill by 2020, for which we have continuously improved the management methodology each year as well as the disposal method according to the company’s waste management hierarchy. By focusing on the reuse, recycling and recovery of waste, PTTEP has implemented a number of trial projects and outlined their progress in the Sustainability Report. The volume of hazardous waste sent to landfill decreases from year to year due to technological advancements.
NOx, SOx and VOCs are emissions that result primarily from the burning of fossil fuels at our facilities for power generation or heating. In an effort to reduce these emissions, PTTEP continues to improve our energy efficiency and reduce flaring so we can decrease our NOx, SOx and VOCs emissions. Our target is to maintain these emissions intensity below 2012 base year. The performances of NOx, SOx and VOCs emission can be found in Sustainability Report.
In order to achieve Target Zero by being an incident-free organization, our ultimate goal is to reach zero spill incidents. PTTEP has continuously improved the spill preparedness and response system in alignment with local regulations as well as international standards. Spill performance has continuously been monitored as one of the company’s KPIs.
