What Aither Service OÜ does

Aither Service OÜ is a privately held environmental commodities trading and advisory firm, formally domiciled in Tallinn, Estonia, with operating linkage to a Swiss affiliate (Aither Group AG) reflected by a +41 Swiss contact number and a Switzerland-jurisdiction Privacy Policy. Founded in 2022, the company intermediates across the major European and international emissions trading frameworks, trading EU Allowances (EUA), UK Allowances (UKA), Swiss CH ETS allowances, ETS2 instruments, CBAM certificates, CORSIA credits, and Renewable Energy Certificates (Guarantees of Origin, Green Power Certificates, Gas Power/Biomethane Certificates).

The firm organizes its offering into three lines. First, Trading: clients transact environmental commodities through Aither for compliance and hedging, generating revenue from spreads and transaction fees. Second, Sustainability Advisory: consulting on Corporate Social Responsibility, Corporate Sustainability Reporting Directive (CSRD), and Corporate Sustainability Due Diligence Action Plans, billed as professional services fees and retainers. Third, Projects Development (branded Aither Impact): an in-house carbon engineering team designs and structures verified carbon and plastic credit projects across Nature-Based Solutions (forestry, soil, ecosystem restoration) and Technology-Based Solutions (clean cookstoves, e-mobility, energy transition), guiding developers through Gold Standard, Verra, GCC, and CDM certifications.

Aither serves regulated enterprise clients across maritime operators (EU ETS maritime, FuelEU, pooling, biomethane/Bio-LNG procurement), aircraft operators (CORSIA, Gold Standard CORSIA-labeled credits), energy-intensive manufacturers (EU ETS, CBAM, decarbonization advisory), and Italian energivore enterprises (Guarantees of Origin for Green Conditionality compliance). The go-to-market is direct enterprise B2B via the website (Schedule a Call, Send a Request), supplemented by sector desks, conference presence (e.g., London Climate Week), and thought leadership across five email newsletters and a regularly updated blog covering EU ETS market overviews, CBAM, CORSIA, FuelEU, and renewables. The company does not disclose headcount, revenue, or external funding.
