Activités: 

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 2003 and are a driving force behind some of the world's most trusted data in aviation environmental policy.

Références: 

Airport emissions and ACA (Airport carbon accreditation):

In the last years, ENVISA provided  "ACA" carbon accreditation support to airports worldwide. Many airports including heliports received their Level 1, Level 2 and Level 3-3+ accreditation thanks to dedicated best practice methodologies and data provision by Envisa's expert team.

As a result of growing concern for air quality, Envisa has conducted a number of airport emission studies in the framework of the ALAQS project, but also in other contexts. Among others, ENVISA staff conducted emission inventories for European airports such as Bucharest Henri Coanda Int’l, Warsaw Chopin Int’l, London Heathrow, London City, Nice, Lyon, ADP, etc. ENVISA has been involved in the development of ICAO/CAEP airport emission and local air quality guidance material.

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.

Green Technology Assessment:

ENVISA has supported SAFRAN/Honeywell in assessing the environmental benefits of EGTS, an innovative electric green taxiing system that will deliver significant fuel savings for airlines as well as reducing aviation emissions at airports. ENVISA developed a detailed ground movement assessment method based on ICAO recognized data sources and methods.

NATS assessment of Local Air Quality:

ENVISA provided UK NATS with local air quality studies (aircraft emission inventories and dispersion analyses) at Heathrow and London City in order to evaluate the environmental impact of changes in operating procedures in the context of the development of Heathrow’s third runway. 

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.

SUSTAIN:

ENVISA developed a set of indicators of air transport sustainability for EUROCONTROL. The three domains of sustainability were considered: social, economic and environmental sustainability. Various sets of indicators were derived for each actor of the air transport industry: manufacturers, airlines, airports, air navigation services providers, and the society.
