However, with the exception of what is now characterized as a largely symbolic purchase by the government of Norway of 200 million tons of carbon sequestration for US$2 million, along with a few minor bilateral and philanthropic deals, no other major sale has occurred. World Bank financing and Global Environment Facility grants that began in 2001 now total more than US$80 million. Bilateral assistance has come from Kreditanstalt fur Wiederaufbau Bank, the Norwegian Agency for Development Cooperation and the Government of Japan. Approximately one third of the PES programme revenue has come through these channels.
