Since 2005, the Walloon Region awards an investment subsidy and an exemption from real estate taxes to companies which carry out an investment programme aiming at a sustainable use of energy (hydroelectric energy, wind energy, solar energy, geothermal energy, biogas, organic products and waste from agriculture and forestry arboriculture, biodegradable organic part of waste), a quality cogeneration and energy savings during the manufacturing process. Certain sectors are excluded form the scheme (e.g. the energy sector). The overall amount of the subsidy and the exemption from real estate taxes covers a percentage of eligible investments. The rates of the supports depend on the size of the enterprise and the objective of the investment programme. It can be 20%, 25% and 30% for large companies (depending on geographical area), and 50% for SMEs. (See reference below for more details.)
