In 1974, Claes Nobel drafted The Nobel Laureates Declaration on the Survival of Mankind, which was signed by 78 Nobel Laureates. This historic document recognizes the great achievements wrought by individuals working in technical disciplines, while also acknowledging that the application of some of those achievements has unintentionally contributed to current environmental problems. The declaration calls for Nobel Laureates to pledge their active support to conserve, protect and restore our environmental heritage.
In 1985, Claes Nobel authored The Global Declaration of Earth Ethics, signed by thousands of individuals and organizations around the world as testament to their desire for — and willingness to work toward fostering— new standards of humanitarian excellence and environmental stewardship. It has become the United Earth credo.
