The objective of this project is to carry out an in-depth analysis of waste generation and treatment data received in June 2014 on the basis of the Waste Statistics Regulation. The project other main aim is the validation of the food waste statistics that will be reported by ~ 16 countries together with their waste data on the basis of the 'food waste plug in' template.

Buildings, by their use of fossil energy for heat and cooking, are one of the major sources of energy expenditures (23% of final-use energy consumption in 2008 in Wallonia) and consequently of emission of greenhouse gases. Potential for improvement is even greater because performances of residential housing remain low. Inhabitants (generally simple citizens) are at times badly informed about what they could do to improve their performances, reduce their consumption and cut their energy bills.

The status of the regional spatial development plan (SDER) is defined by the Walloon Code for Land-use planning, Urbanism, Heritage and Energy (Code Wallon de l'Aménagement du Territoire, de l'Urbanisme, du Patrimoine et de l'Énergie - CWATUPE) as a non-binding design tool for land-use planning.

The SDER describes options for land-use planning and sustainable development for the entire Walloon Regional Territory.

Administrative simplification and rationalization of requests for information

The Walloon Region has embarked on an ambitious approach to administrative simplification and rationalization of requests for information.

Until 2003, environmental data were collected by various administrative services corresponding to their competence. This led to a certain amount of overlapping at times in requests for information addressed to businesses. Among other things, environmental regulations are complex and evolving constantly, which increases the need for smooth exchanges of information between businesses and the competent administrative services.

At the beginning of the nineties, the Walloon Region proposed to conclude voluntary agreements with industrial sectors to reduce emissions of greenhouse gases and to improve their energy efficiency: these are the branch agreements. Since the signature of the first agreements, most industrial federations have joined this approach.

Purpose of the project (and limits)

The study defines different paths that can lead to an energy system based exclusively on renewable energy sources.
How to achieve a 100% renewable target in 2050 (electricity, heating and cooling, transport except aviation and sea transport)?
