ENVISA is an international environmental research and Consultancy Company specializing in finding innovative solutions to reduce the environmental footprint of aviation industry. ENVISA provides airports industry with a unique offer of integrated services for environmental management.
Steadily increasing demand for air transport means that airports are faced with capacity constraints. Airports are highly concerned with understanding how to address the challenges of sustainable growth. ENVISA provide the world’s leading aviation stakeholders with cutting edge analytical tools for traffic and demand forecasting, noise impacts, local air quality studies, global emissions and cradle-to-grave carbon foot printing.
Carbon management is not only part of environment strategy but also a means of increasing the efficiency of airport operations and energy use. As one of Europe’s most innovative aviation environmental research companies, ENVISA believes responsible environmental stewardship is not only a fundamental part of doing business; it is at the core of who we are as a company.
ENVISA have been conceiving, designing, developing, validating and consulting with environmental models since 2004 and are a driving force behind some of the world's most trusted data in aviation environmental policy.

• designing and developing flight movement and gate-to-gate trajectory databases,
• performing ATM market and cost-benefit analyses.
ENVISA’s services to aircraft and engine manufacturers include:
• investigating future regulatory and operational concepts for aviation and their environmental / economic impact,
• investigating the environmental benefits of future propulsion technologies,
• assessing the environmental impact of new flight procedures either en-route or during the Landing and Take-Off (LTO) cycle.
AUDITING AND BEST PRACTICES
• Planning: Strategic and Environmental planning, Airport infrastructure planning and design, and International project coordination.
• Assessment: Environmental impact (EMS), Environmental performance, Evaluation/reduction of carbon footprint (ISO 14064, ACI-ACA), Emissions and waste, Environmental tradeoffs (emissions, noise, fuel, air pollution).
• Management: including basic concepts of environmental concerns in aviation, Legal framework for aviation, Environmental control and reporting, ATM/ATC environmental concept development, Cost benefits and efficiency, Safety and security solutions, Integrated management system, Performance based project management, Global Emissions Best Practices, and guidance for best practice on aircraft noise management.
Airport emissions and ACA (Airport carbon accreditation):
ENVISA is the global leader for "ACA" carbon accreditation support to airports worldwide. More than 100 airports including heliports received their Level 1, Level 2-3-4 and Level 5 accreditation thanks to dedicated best practice methodologies and data provision by Envisa's expert team.
As a result of growing concern for local environmental impact for communities around the airport, Envisa also developed Air quality, and Noise management support. Envisa has conducted a number of airport studies.
Env-isa, since 2004, has been involved in airport air quality management. Env-isa offers internationally accredited solutions and models (ICAO/CAEP) tailored to airports (LASPORT, Open-ALAQS etc..). In addition to involvement in European research projects like CleanSky (RAPTOR for ultrafine particles), OLGA (hOListic Green Airport ) Env-isa has carried out numerous consulting and auditing missions, creating innovative tools for the airport sector.
Some of our combined air quality monitoring (low cost) and modelling case studies include:
King Khalid International Airport, Saudi Arabia (2019–Present) – Real-Time Monitoring and Air Quality & Emissions Analysis: Several low-cost stations have been set up to monitor air quality, measuring pollutants such as PM1, PM2.5, PM10, NO, NO2, H2S, SO2, CO, CO2, and O3. Additionally, in house environmental dashboard was created, helping to correlate pollutant events with environmental conditions, aircraft movements, and many more customized parameters.
Groupe ADP (since 2019) – ADP -- Air Quality Assessment for Paris-Charles de Gaulle Airport Terminal 4 Project. (atmospheric pollutant dispersion modeling for various scenarios, considering the most relevant airport emission sources. Additionally, sustainable solutions like single-engine taxiing, green taxiing, and biofuels were incorporated into this study.) Since 2023, framework contract for noise and air quality assessment forall 3 airports in Ile-de-France.
Environmental Regulations Support for EASA:
ENVISA is supporting EASA under two framework contracts for the development of CO2 metrics and assessments of a range of proposed metrics against a large variety of criteria under ICOA/CAEP. These assessments have been reported to the CAEP WG3 CO2TG meetings and have contributed to the agreement of a metric system.
EASA/EUROCONTROL STAPES (System for Airport Noise Exposure Studies):
ENVISA was in charge of collecting and formatting the input flight movement data for the 28 airports in EUROCONTROL’s multi-airport noise model STAPES. This included the processing of the CAEP/8 data for the STAPES airports.
Open ALAQS:
ENVISA has developed, validated and maintained EUROCONTROL's Airport Local Air Quality Studies (ALAQS) over the past 10 years. This includes the coding of the fundamental core of the model and its interface, integration with ArcGIS for graphically visualising and manipulating data, and post processing outputs for use by other applications. ENVISA also conducted the full ICAO CAEP Verification & Validation process for aviation Local Air Quality models with ALAQS. ENVISA collaborated with Henri Coanda airport on the ALAQS case study, where emissions and local air quality modeling is conducted. Finally, ENVISA was recently awarded a contract to convert ALAQS from ArcView, a commercial GIS, to an open source GIS software, QGIS.
World Interconnected Sources Database of Operational Movements – WISDOM:
ENVISA was mandated to improve the quality of EUROCONTROL’s WISDOM database of global flight movements and trajectories, notably by designing interfaces with Geographic Information Systems (GIS).
CO2 Metric (ICAO):
ENVISA developed more than a hundred candidate metrics for aircraft CO2 emissions based on technical parameters such as wingspan, take-off weight, floor area, number of seats, payload, etc. in support of the EASA for the selection and definition of new ICAO CO2 metric (recently approved in July 2012 by the CAEP Steering Committee).
Traffic / Demand Forecast:
The aim of this EUROCONTROL project is to provide a new statistical methodology for forecasting traffic demand in the short, medium and long term. Unlike previous models, these forecasts make use of confirmed future flight intentions as well as historical trends to more accurately generate a baseline from which the forecasting model can run. The objectives are to take the expert knowledge of the individuals who currently perform this task based on years of experience and intuition and to generate a statistical method based on this knowledge that is capable of reliably and consistently predicting baseline cases with an indication of their likely representativeness. This activity belongs to the project P7.6.5 DCB as part of the SESAR Work Package 07.
