With public concern growing about global warming and the strengthening of international environmental legislation, accurately estimating current and future emissions is of the highest importance, notably to support efficient and unbiased political decision making.

ENVISA’s activities in the domain of transportation emissions, and more specifically aviation emissions, cover a wide range of aspects including:

• designing, developing and validating fuel burn and emission models
• developing comparative ‘what if’ scenarios and traffic forecasts
• investigating alternative fuel solutions
• mapping with Geographic Information Systems (GIS)
• reporting to regulatory and controlling authorities

For details on our past and present activities related to global emissions see the projects below:
