Altogether 48 developing countries have committed here on Friday to produce 100 percent of their energy needs from renewable energy sources.The countries are also to eliminate high-carbon investments and harmful subsidies under the commitment, which is adopted at a high-level meeting of the Climate Vulnerable Forum (CVF) on the last day of the Moroccan Climate Change Conference.The document was adopted by the 43 original members of CVF and five other parties, namely Lebanon, Palestine, Samoa, Gambia and Columbia, who joined today and adopted at the same time.They pledged to cooperate in national plans of energy transforming, transport and other sectors to support capacity building, financing, and technology.Former US vice president and environmental activist Al Gore said the move represents a bold vision that "sets the pace for the world's efforts to implement the Paris Agreement and move even more quickly to solve the climate crisis.""Their move is globally significant as the carbon pollution from these countries is roughly equal to that of Russia," said Greenpeace International Executive Director Jennifer Morgan.
