LCA & openLCA Training for PETRONAS Malaysia | DEISO Case Study

Enterprise Case Example

Strengthening Applied LCA Capability in the Chemical Industry for PETRONAS Through an Integrated Technical Sustainability Engagement

DEISO supported PETRONAS in Malaysia through a structured technical engagement designed to strengthen internal capability in lifecycle-based environmental assessment, openLCA-based implementation, and practical interpretation of environmental results for chemical and petrochemical systems.

How Capacity Building Was Positioned in This Engagement

This engagement should not be interpreted as a standalone training service. It was delivered as part of DEISO’s broader technical sustainability approach, where capacity building is integrated to strengthen internal implementation environments, software-based analytical capability, and lifecycle-oriented decision support in complex industrial contexts.

DEISO’s role was to help participants interact more effectively with LCA methodology, openLCA workflows, and chemical-system modeling logic so that lifecycle analysis could be applied more confidently within operational and sustainability-related contexts.

Executive Summary

DEISO delivered two specialized Life Cycle Assessment engagements for PETRONAS in Malaysia, targeted at professionals working in the chemical industry. The work combined LCA methodology with practical implementation using openLCA, helping participants strengthen applied capability in lifecycle modeling and environmental impact assessment for chemical systems.

The engagement was designed to bridge the gap between conceptual understanding and practical implementation, enabling stronger internal readiness to use LCA in chemical and industrial sustainability contexts.

Client Profile

  • Organization Type: Integrated energy and chemical company
  • Region: Malaysia
  • Industry Focus: Chemical and petrochemical sector
  • Delivery Format: On-site structured engagement
  • Program Structure: Two LCA-focused capability-building modules delivered within one engagement

Strategic Challenge

PETRONAS required stronger internal capability to evaluate environmental impacts across chemical processes and product systems. The need extended beyond methodological understanding and included practical implementation using LCA software tools and structured lifecycle modeling logic.

  • Limited internal capability in lifecycle-based environmental assessment
  • Challenges in modeling complex chemical production systems
  • Limited hands-on experience in openLCA implementation
  • Difficulty connecting process data with environmental impact results
  • Need to support sustainability and carbon-related initiatives within chemical operations

DEISO’s Integrated Technical Role

DEISO acted as a technical sustainability partner, designing a structured engagement tailored to the chemical industry. The work combined lifecycle methodology, openLCA-based implementation, chemical-system modeling logic, and decision-oriented interpretation support.

Rather than delivering generic LCA training, DEISO strengthened the internal implementation environment needed for more confident environmental analysis, stronger lifecycle modeling capability, and more practical use of LCA in industrial decision-making.

Technical Execution

The engagement was delivered between October 22 and October 25, 2023 and integrated three practical capability areas required for lifecycle work in chemical and petrochemical systems:

  • LCA Methodology for Chemical Systems: goal and scope definition, functional unit development, and system boundary selection aligned with chemical production settings
  • openLCA-Based Modeling and Implementation: process modeling, dataset integration, emission factor use, and Life Cycle Inventory development for chemical products
  • Impact Assessment and Interpretation: application of LCIA methods, environmental hotspot identification, and results interpretation for sustainability-oriented decision-making

Participants worked directly on applied scenarios reflecting chemical industry conditions, including systems with multiple inputs and outputs, allocation challenges, and lifecycle-stage impact evaluation.

Industry-specific implementation value: the engagement combined methodological rigor with software-based execution, allowing participants to move from conceptual understanding toward more applied lifecycle modeling capability within real industrial conditions.

Measurable Outcomes

Following the engagement, participants demonstrated stronger practical capability in openLCA-based implementation, lifecycle data structuring, and interpretation of environmental performance results for chemical systems.

openLCA Capability
Improved ability to develop and work with LCA models using openLCA
~60%
Improvement in system modeling accuracy during the engagement
Applied Readiness
Stronger capability to connect process data with environmental performance results in industrial contexts
  • Enhanced capability in LCI structuring and dataset integration
  • Improved understanding of impact assessment and hotspot analysis
  • Greater confidence in applying LCA within chemical and industrial environments
  • Stronger internal support for sustainability and carbon-related initiatives

Strategic Value

Participants progressed from conceptual understanding toward stronger applied LCA modeling capability, enabling better internal execution of lifecycle studies for chemical systems and stronger integration of environmental analysis into engineering and operational decisions.

Why This Engagement Matters

In the chemical industry, environmental impact assessment requires both methodological rigor and practical modeling capability. This engagement demonstrates the importance of combining lifecycle methodology, software implementation, and industry-specific system understanding within one structured technical approach.

Seven ways to start

Choose the entry point that fits where you are

Not every visitor knows what they need on day one. These seven onboarding paths cover the full range — from knowing exactly which service you want to starting from a question and letting AI guide you. Pick whichever fits.

1If you know what you needRecommended Find the right DEISO service Match your requirement to the right DEISO service in a few clicks. Filter by LCA, GHG, PCF, EPD, ESG, critical review, S-LCA, waste, circular economy, EIA, and more. Fastest path if you already know the scope. Good for “We need Scope 3 review and pre-submission checks before verification” or “We need an EPD prepared for EN 15804.” Open service finder → 2If you’re building internal capabilityRecommended Explore capacity building programs Match your team to the right DEISO training program — LCA, GHG accounting, PCF, EPD development, ESG reporting, environmental review, ISO 14001, and sector programs. Filter by role, level and format. Good for Teams building in-house LCA, GHG or EPD capability, and organisations aligned with workforce development priorities such as Saudi Arabia Vision 2030.
