What Lemma OÜ does

Lemma OÜ is an Estonian environmental consulting firm headquartered in Tallinn that has been operating since 2007 (rebranded from Adepte Ekspert in October 2019). The firm delivers a comprehensive suite of environmental services spanning environmental permit applications for air, waste, water, and integrated permits; environmental impact assessments (EIA) and strategic environmental assessments (SEA); expert assessments and opinions; computational noise and air quality modeling; certified water sampling and pollution studies; municipal waste management plans; and more recently, climate resilience, DNSH ('Do No Significant Harm') assessments, and wind/solar park visualizations.

The firm's technical backbone consists of third-party specialized modeling and GIS software — WindPRO (wind farm noise, shadow, and visibility modules), AERMOD View and AEROPOL (air dispersion), SoundPlan Essential (noise mapping), and ArcGIS Pro / MapInfo Professional — operated by licensed experts rather than built as proprietary technology. Board member Piret Toonpere holds EIA license KMH 0153, one of a small pool of such Estonian license holders, and the team includes multiple certified water samplers and specialists across air, noise, waste, climate, and geotechnology domains.

Lemma generates revenue through professional services engagements: project-based fees for permit applications, impact assessments, and modeling work, supplemented by a subscription-style Environmental Specialist Full Service package (fixed monthly fee plus measurement costs) and a quarterly per-report tier for recurring compliance reporting. Customers are primarily Estonian industrial and manufacturing companies (e.g., Enefit Green, Enefit Power, Stora Enso Eesti, Utilitas Tallinn), local municipalities and government entities, and renewable energy project developers. The go-to-market is direct enterprise consulting supported by a multilingual website (Estonian, English, Russian), with no channel intermediaries. Since 2007, Lemma reports having completed over 2,000 environmental projects, consulted nearly 200 companies, and developed waste management plans for more than 30 municipalities.

Expansion highlights4 records

Broad incumbents

• AFRY (formerly Pöyry): Nordic engineering and design consultancy with environmental and permitting services, particularly for energy and renewables projects. Comparable due to overlap in wind/solar EIA, permitting, and visualization-adjacent services relevant to Lemma's renewables work.
• ERM (Environmental Resources Management): Global pure-play environmental, health, and safety consulting firm. Directly comparable service offering to Lemma, including permitting, impact assessment, air quality, and compliance, though ERM operates globally with much larger teams.
• Ramboll Group: Global engineering and environmental consulting firm with significant Nordic/Baltic presence and broad EHS, EIA, and permitting practices. Directly comparable to Lemma's environmental consulting scope but operates at much larger scale across multiple geographies and sectors.
• WSP Global: International professional services firm with dedicated environment and EIA practices. Comparable because WSP delivers environmental impact assessments, permitting support, and noise/air modeling for infrastructure and energy clients similar to Lemma's customer base.
• Sweco AB: European engineering consultancy headquartered in the Nordics with extensive environmental assessment and permitting services. Comparable because of regional Nordic/Baltic proximity and similar EIA, water, and waste consulting practice relevant to Lemma's Estonian market.
• AECOM: Global infrastructure consulting firm with a substantial environment practice spanning EIAs, permitting, and air/noise modeling. Comparable to Lemma in service mix (EIA, permitting, modelling) but with global delivery capacity and larger project scale.
• Arcadis NV: Sustainable design and consultancy with dedicated environmental and permitting services across Europe. Comparable due to overlapping offerings in environmental impact assessment, air quality, and waste/water permitting for industrial and energy clients.

Regional players

• SLP (Suomen Luontosieto Oy / Finnish environmental consultancies): Finnish environmental and infrastructure consulting firm providing EIA, permitting, and noise/air modeling services in the Nordic/Baltic region. Comparable due to similar service mix and Nordic-Baltic geographic proximity, though operating in Finland rather than Estonia.
• Estonian Environmental Research Centre (EKUK): Estonian state-owned environmental laboratory and research centre conducting water sampling, air quality measurements, and pollution studies. Comparable because it directly overlaps with Lemma's certified sampling and analysis services within the same Estonian market.

Others

• Keskkonnaamet (Estonian Environmental Board) registered EIA experts list: While not a direct competitor, the registry and licensing regime managed by the Estonian Environmental Board defines the constrained EIA license pool that Lemma participates in; understanding this ecosystem is essential to peer benchmarking because the regulatory body effectively governs all market participants' ability to deliver EIAs in Estonia.
