In the G8 summit's declaration Growth and Responsibility in the World Economy, the G8 invites GBEP to take an active role in building a sustainable bioenergy future, especially in the transportation sector. The G8 partners agreed to "avoid possible negative side-effects in biofuel development, particularly in developing countries in order to prevent competition between different forms of land uses, and promote sustainability in biomass cultivation, ... [and] invite the Global Bioenergy Partnership (GBEP) to continue its work on biofuel best practices and take forward the successful and sustainable development of bioenergy". The G8 also welcomed "concerted global action to promote renewable energy and the support of interested parties for initiatives and partnerships such as the Renewable Energy Policy Network for the 21st Century (REN21), the Renewable Energy and Energy Efficiency Program (REEEP), the Global Bio-Energy Partnership (GBEP) and the Mediterranean Renewable Energy Partnership (MEDREP)."
