Atlas — Carbon Transformation Roadmap

International standards, emission calculation methodologies, and our technical reference source.

"Without a rigorous, auditable greenhouse gas inventory, no decarbonization plan can succeed; the GHG Protocol and ISO 14064 are the indispensable compass of this transition," stated Lead Carbon Auditor Deniz Yaman.

What are the emissions accounting methodologies outlined in Optima Atlas?

Optima Atlas is an engineering reference index establishing corporate greenhouse gas accounting based on the GHG Protocol Corporate Standard (Scopes 1, 2, and 3), ISO 14064 verification protocols, and SBTi 1.5°C science-based targets.

Scientific and Transparent Infrastructure

Optima Atlas contains the scientific methodologies and calculation standards we use in our emission reduction and green transformation projects. All our analyses are based on the GHG Protocol and ISO 14064 standards.

GHG Protocol

The most widely used global standard for calculating and reporting corporate greenhouse gas inventories.

ISO 14064

ISO standard defining the rules for verification of greenhouse gas claims, organization-level monitoring, and auditing.

SBTi Alignment

Setting science-based emission reduction targets and alignment with the global 1.5°C pathway.

GHG Standards & Accounting Methodology FAQ

What is the distinction between Scope 1, Scope 2, and Scope 3 emissions?+

Scope 1 covers direct emissions from on-site fuel combustion and chemical processes; Scope 2 accounts for indirect emissions from purchased electricity and steam; Scope 3 encompasses full value chain and supplier emissions.

How long does third-party ISO 14064 verification take?+

Depending on plant complexity and data readiness, data collection, emission factor modeling, and third-party audit typically conclude within 4 to 8 weeks.
