About Aretia

Building the backbone of climate accountability.

A mission-driven technology company with one purpose: to make rigorous, science-based climate disclosure accessible to every organisation on earth.

Our Mission

Climate truth for every organisation.

When the ISSB released IFRS S1 and S2, it created an opportunity: and a burden. Large companies with armies of ESG consultants adapted quickly. Mid-market and emerging-market companies were left with complex standards, manual spreadsheets, and mounting regulatory pressure.

Aretia was built to close that gap. We combine the rigour of institutional-grade climate science with the accessibility of modern software: so that a 500-person manufacturer in Lagos or Nairobi can produce a disclosure report that meets the same standard as a multinational listed on the London Stock Exchange.

Science-based: all calculations reference IPCC AR6 and NGFS v4 data
Audit-ready: methodology documented for external assurance
Regulation-aligned: ISSB IFRS S1 and S2, GHG Protocol, ESRS E1
Mission-driven: climate impact, not short-term profit, drives our roadmap

What We Stand For

Six principles. One direction.

Every decision we make: from product design to pricing: is guided by these commitments.

Precision

Every number must be auditable. We build to the standard that external assurance providers demand: methodology documented, evidence traceable, output defensible.

Accessibility

World-class climate tools should not be the preserve of large corporates. We build for every company, from a 200-person manufacturer to a listed multinational.

Intelligence

We combine real scientific data with contextual analysis to surface insights that manual spreadsheets never could: automatically, at scale.

Integrity

We do not sell carbon credits or offsets. Our only product is truth: accurate, transparent disclosure that stands up to scrutiny.

Impact

Profits fund climate literacy programmes and open research in low-income communities globally. Every subscription contributes to something beyond the platform.

Partnership

We embed alongside finance and sustainability teams as a long-term partner, not a one-time tool vendor. Your success is measured in our roadmap.

Mission-Driven

Purpose at the core.

Aretia Climate LLC is incorporated in Delaware, USA, with a mission to advance climate resilience across global markets. Every dollar of surplus is reinvested into the platform, into open climate-data research, and into climate literacy programmes reaching over 40,000 students annually. Our structure means every decision is anchored in long-term climate impact rather than short-term investor pressure.
