Meet our Team

Who we are

Inspired by the Latin ala (wing), terra (land), and mare (sea), Altemar reflects our commitment to protecting the natural balance between air, land, and water.

Founded in 2001 and based in Greystones, Co. Wicklow, Altemar is a trusted environmental and marine consultancy with over 23 years’ experience supporting projects across Ireland. We bridge the gap between engineering and legislation with practical, science-led solutions that respect the natural environment.

Our multidisciplinary team includes ecologists, marine biologists, and environmental scientists who advise on projects in infrastructure, renewable energy, aviation, housing, and commercial development. In the past three years alone, we have delivered more than 250 ecological reports, ranging from one-off housing to nationally significant developments.

Our services include:

  • Environmental constraints assessments and baseline surveys

  • Appropriate Assessment Screenings and Natura Impact Statements

  • Ecological Impact Assessments (EcIA) and biodiversity reporting

  • GIS mapping, habitat surveys, and invasive species assessments

  • Mitigation design, compliance monitoring, and Ecological Clerk of Works (ECoW)

Altemar has acted as environmental lead on major projects including Dublin Airport’s Drainage Masterplan, runway upgrades, and large-scale distribution centres for Lidl and Primark. We also provide specialist expertise in biodiversity net gain and protected species management, including badger translocations in consultation with NPWS. We have delivered a broad spectrum of marine and environmental projects, partnering with leading organisations including Cairn, Ballymore, Durkan, Glenveagh, the Land Development Agency, Lioncor, Ronan Group, Marlet, Gas Networks Ireland and Tetrarch.

At Altemar, we combine scientific expertise with clear communication and collaboration — delivering sustainable, efficient solutions that meet project goals while protecting ecosystems.
