Every year, SGI President Daisaku Ikeda publishes a peace proposal which explores the interrelation between core Buddhist concepts and the diverse challenges global society faces in the effort to realize peace and human security. In addition, he has also made proposals touching on issues such as education reform, the environment, the United Nations and nuclear abolition. – Source (much more information more at this source)

I also located this excellent definition:

Every year on January 26th, SGI President Ikeda publishes a peace proposal which explores the interrelation between core Buddhist concepts and the diverse challenges global society faces in the effort to realize peace and human security. The proposal is sent to wide range of groups and individuals in the international community, including governments, libraries, academic institutions, non-governmental organizations and United Nations officials. – Source is Unknown however, it is believed it was written by a Soka Gakkai (SGI) member.

(I have access to just about every single proposal that has a wealth of information for a peaceful and sustainable world based on a humanistic and compassionate approach, it highlights the importance of how each of us is in essence a world citizen and how each and every individual is highly valued.)
