What Antaris Consulting does

Antaris Consulting is an Ireland-based independent sustainability and ISO management systems consultancy founded in 1994 in Limerick. The firm delivers professional services across ISO 9001, 14001, 45001, 50001, 27001 and related standards implementation, greenhouse gas management and decarbonisation, EcoVadis and B Corp certification support, sustainability reporting (CSRD, CDP, GRI, UN Global Compact), energy management, circular economy, climate adaptation, water stewardship, occupational health and safety compliance, and quality management. It also operates the Antaris Academy, delivering CQI & IRCA, IEMA and NEBOSH accredited training programmes, and provides sustainability grant application support on government-funded schemes including LEO Green for Business, Enterprise Ireland GreenStart, GreenPlus, Climate Action Voucher, Strategic Consultancy Grant, and SEAI programmes.

The business operates on a sales-led, professional services engagement model with consulting rates referenced at €900/day, revenue generated through direct client engagements, training delivery, and grant-funded SME programmes where Antaris acts as an approved service provider on government green directories. Customer segments span Irish SMEs and large enterprises across manufacturing, pharma, energy, utilities, food and beverage, healthcare, technology, construction, maritime and government sectors, with a disclosed enterprise roster including ESB, Energia, Irish Water, Johnson & Johnson Vision Care, Stryker, SAP, Kingspan, Mercury, Doyle Shipping Group, Irish Distillers, Kerry, Serosep, Weener Plastics and Irish Coast Guard. Go-to-market leverages content marketing, case studies, Environment Ireland conference participation, government agency partnerships, and EcoVadis partner network referral channels.

The company is privately held with no external funding, no parent entity, and no subsidiaries. In February 2026, Antaris completed a strategic merger with Pragmatica Consulting, consolidating Cork, Dublin and Kildare offices under the Antaris umbrella to form one of the larger sustainability consultancies in the Irish market with over 45 services and 30+ years of combined experience. The firm holds multiple ISO certifications, EcoVadis Gold (top 5% globally, 2024), SBTi commitment and 1% for the Planet membership, and is led by CEO Eugene Cush (appointed 2025), CFO Áine Collins, COO Gillian Peters and CSO Pat Kane.
