The concept is also promoted as a tool to reduce carbon emissions. Peter Barnes created the concept of "Sky Trust" as an example of how this could be implemented. Barnes proposes setting up a public trust to manage the funds, separate from the private sector being taxed. A calculation based on specific assets by Barnes estimates that American citizens could each get $5,000 per year by this model. A Swiss campaign in 2013 advocated for a citizen's income which could net each citizen an amount equivalent to $34,000 dollars. A citizens dividend based on resources according to Thomas Pogge is due to every citizen because everyone owns an inalienable stake in all limited natural resources. His theory goes along with Barnes with the exception of ownership, Pogge contends that the people own the resources. "The Progress Report" says that the dividend should be valued by the free market.
