ESG Consulting & Reporting

From strategy architecture to assurance-ready reporting, DEISO embeds ESG into operational systems, governance frameworks, and measurable performance structures. Our work supports regulatory alignment, investor due diligence, and defensible sustainability execution across global industries.

Greenhouse Gas (GHG) Accounting & Climate Strategy

Structured Scope 1–3 emissions quantification aligned with ISO 14064 and the GHG Protocol. We deliver defensible carbon accounting, verification-ready documentation, and climate strategy integration designed for regulatory compliance, investor scrutiny, and governance-level decision-making.

Enterprise Life Cycle Assessment (LCA)

Comprehensive, ISO-aligned environmental impact analysis enabling carbon reduction, compliance readiness, and competitive sustainability positioning.

Enterprise Social Life Cycle Assessment (S-LCA)

We conduct comprehensive Social Life Cycle Assessments (S-LCA) to evaluate the social and socio-economic impacts embedded within your supply chains and operations. Our structured approach examines labor conditions, human rights exposure, community impact, governance practices, and supplier-level risk across defined system boundaries. By identifying social hotspots and high-risk sourcing regions, we equip your organization with defensible ESG intelligence, due diligence readiness, and procurement-level risk prioritization. S-LCA converts social responsibility into structured enterprise risk governance.
