Carbon Pricing

In response to climate-related risk management, PT Pupuk Sriwidjaja Palembang (PUSRI) utilizes an internal carbon pricing mechanism as part of its efforts to manage and reduce greenhouse gas (GHG) emissions. The company's internal carbon price is applied across Scope 1, Scope 2, and Scope 3 emissions, reflecting its comprehensive approach to GHG management throughout its value chain. The objectives of this carbon pricing include driving energy efficiency, incentivizing low-carbon investments, incorporating climate-related issues into decision-making and risk assessment, and ensuring alignment with climate-related policies and targets.

As detailed in the press release from IDX Carbon, PUSRI applies a shadow price for carbon at IDR 96,000 per metric tonne of CO2e. This price is utilized to evaluate potential investment decisions, optimize energy efficiency, and assess the financial implications of climate-related risks. The internal carbon price also helps to set a carbon offset budget and guide financial planning for the company's low-carbon transition.

Beyond Net Zero Commitment

PUSRI has committed to a Net-Zero target by 2060, which includes reducing Scope 1, Scope 2, and Scope 3 emissions to zero by that year. The company aligns with the Decarbonization Roadmap outlined for 2060 and has integrated its climate action plans accordingly. While the target has not yet been formally validated by the Science Based Targets initiative (SBTi), PUSRI recognizes it as science-based and committed to pursuing validation in the future. This target encompasses a full reduction of emissions in all scopes by 2060, supporting PUSRI's long-term commitment to sustainability and climate risk management.

This target encompasses a full reduction of emissions in all scopes by 2060, supporting PUSRIs long - term commitment to sustainability and climate risk management.

Renewable Energy Certificates (REC)

PUSRI integrates Renewable Energy Certificates (REC) as part of its net-zero commitment by neutralizing residual emissions through credible, market-based renewable energy procurement. In 2025, PUSRI retired 300 REC units for the Jakarta Representative Office, verified through the TIGR Registry, sourced from the Saguling Hydropower Plant. Each retired REC represents 1 MWh of certified renewable electricity, ensuring no double counting and full environmental attribute ownership. This initiative supports PUSRI’s strategy to mitigate emissions beyond its value chain and offset unavoidable operational emissions while Indonesia’s fertilizer sector continues transitioning away from fossil-based processes. REC usage complements ongoing decarbonization efforts, including energy-efficiency programs, biomass co-firing, and the company’s long-term net-zero roadmap. Through REC retirement, PUSRI strengthens the credibility of its ESG performance and demonstrates active contribution to the national renewable-energy transition

Renewable Raw Materials

In 2024, water is used as the primary raw material in the fertilizer production process at PT Pusri, and water is considered an important renewable raw material. While natural gas remains the dominant primary raw material, water plays a crucial role in supporting the sustainability of fertilizer production. Additionally, Pusri integrates biomass (sawdust) into its co-firing process in the boiler system, contributing to the reduction of reliance on fossil fuels.

Percentage of Renewable Raw Materials Used in Production for 2024: The percentage of renewable raw materials used in the production process for 2024 is 1.55%. This includes the use of water and biomass (sawdust), with water being the primary contributor. The total raw materials used for fertilizer production in 2024 are calculated by adding natural gas, water, and sawdust (biomass):

  • - Natural gas (converted to m³): 927,871,669,120 m³
  • - Water: 14,616,240 m³
  • - Sawdust (biomass): 35,000 m³ (converted from 50,000 tons)
