Through this mechanism, WEGE strengthens the integration of climate considerations into performance management, enhances internal accountability, and ensures that ESG and climate-related targets are embedded as part of the Company’s strategic priorities.
WEGE has conducted a qualitative climate scenario analysis to assess how climate-related transition and physical risks may affect the Company’s operations, strategy, and financial performance over time. The analysis complements the Climate Risk Assessment (CRA) by evaluating how external climate-related developments may influence risk profiles, business opportunities, investment needs, and the implementation direction of the Company’s Net Zero Emission (NZE) Roadmap.
For transition risk analysis, WEGE applies the NGFS 2°C or below scenario, which is considered relevant to the Company’s business context and Indonesia’s construction industry. This scenario reflects a low-carbon transition pathway driven by stronger climate policies, increasing ESG expectations from investors and customers, wider adoption of green procurement, tighter carbon-related regulations, and accelerated development of low-carbon technologies. Under this scenario, WEGE assesses potential implications such as increasing demand for green buildings, modular construction, energy-efficient design, and low-carbon construction solutions.
For physical climate risk analysis, WEGE applies the RCP 2.6 or SSP1-2.6 scenario, which represents an optimistic climate pathway where global temperature increase is kept below 2°C. Using this scenario, WEGE maps potential physical climate risks, including water stress, flooding, extreme rainfall, and other climate-related hazards across the Company’s operational areas. The analysis is conducted across relevant time horizons, including 2025, 2030, and 2060, to support mitigation planning and strengthen long-term operational resilience.
The results of the climate scenario analysis serve as a basis for prioritizing decarbonization programs, strengthening climate risk mitigation measures, planning investment needs, and aligning the Company’s business strategy with its NZE Roadmap and long-term sustainability objectives.

Sustainable Raw Materials
In an effort to reduce waste, WEGE implements modular products using the Prefabricated Prefinished Volumetric Construction (PPVC) method to minimize construction waste and improve efficiency. The use of modular construction also enhances time and resource efficiency, while supporting the achievement of the company’s sustainability targets.
BENEFITS OF THE PPVC METHOD
- More precise construction quality
- Accelerated project completion time
- Lower environmental impact
- Resource use efficiency
MODULAR COMPONENTS ARE ASSEMBLED OFF-SITE
- The installation process becomes faster and more orderly
- Reduces material waste
- Reduces construction waste
- Minimizes noise and air pollution at the project site
- Creates a safer and cleaner working environment for workers
UTILIZATION OF MATERIAL RESIDUES
- Concrete remaining from the casting process is reused for concrete decking work
- Processing scrap metal into “cakar ayam” elements, steel decks, and safety railings
- Use of fly ash and lightweight brick waste as a partial substitute for sand in floor screed work
- Use of lightweight brick offcuts as a mixture in mortar for wall plastering
- Repurposing used drums as waste bins
OTHER INITIATIVES IN MATERIAL MANAGEMENT
- Development of modular products to reduce emissions and construction waste generated
- Implementation of more environmentally friendly production methods, such as prefabrication, the use of recycled materials, and the selection of local materials sourced within a radius of approximately ±800 km
- Project execution that considers the material life cycle to reduce waste and emissions at each stage of construction
