Environmental Sustainability Assessment – Lifecycle Intelligence, Carbon Analysis & Audit-Ready Insights

Environmental sustainability assessment is a critical foundation for ESG reporting, product transparency, and regulatory compliance. However, many organizations rely on fragmented data and inconsistent methodologies—resulting in low-confidence results, failed verification, and limited decision-making value.

At DEISO, we deliver enterprise-grade environmental assessment services combining lifecycle modeling, carbon accounting, and advanced analytics to generate accurate, defensible, and decision-grade sustainability intelligence.

DEISO Capabilities: Integrated Sustainability Assessment Framework

With over 14 years of experience, DEISO integrates ISO-aligned methodologies, leading LCI databases (e.g., Ecoinvent, Sphera), and advanced modeling tools (SimaPro, openLCA, LCA for Experts) to deliver comprehensive sustainability assessments across industries.

Life Cycle Assessment (LCA)

Our LCA services are aligned with ISO 14040 / 14044 and cover cradle-to-grave environmental performance across products, systems, and processes.

  • Cradle-to-grave lifecycle modeling across multiple industries
  • Hotspot and weak-point identification
  • Sensitivity, uncertainty, and parameter analysis
  • Scenario modeling for alternative materials, technologies, and operations
Greenhouse Gas (GHG) Accounting

We provide structured GHG inventory development aligned with ISO 14064 (Parts 1–3), covering:

  • Scope 1, 2, and 3 emissions quantification
  • Data validation and consistency checks
  • Verification readiness support
Environmental Product Declarations (EPD)

Development of EPDs aligned with ISO 14025 and EN 15804, including:

  • Single-product and multi-product EPDs

  • Scenario development and comparative modeling
  • Sensitivity and uncertainty analysis
  • Monte Carlo simulations and probabilistic modeling
  • AI-supported data analysis and optimization
Optional Integrated Assessments
