Green Century Capital Management will conduct a five-year campaign to inform investors about the financial risks of deforestation, Green Century announced Wednesday.

The Risk In Supply Chains project is designed to inform investors about the growing business and environmental risks of deforestation as part of Green Century Capital Management’s overall efforts to curb global warming.

Tropical deforestation is a major source of global carbon emissions. In the last several years, investors have played a key role in protecting rainforests by pressuring companies to adopt zero-deforestation agreements in the supply chains for the production of palm oil, Green Century says.

The new project will expand this effort to target deforestation in South America and Africa caused by the production of soy, beef, timber and rubber. The project is being led by Climate Advisors in the United States and AidEnvironment and Profundo in Europe.

“When the finance and investment community has been informed of these risks through credible analysis, they have acted as a powerful force for ending deforestation—and we hope that this continues,” says Leslie Samuelrich, president of Green Century Capital Management, the investment advisor to Green Century Funds.

“The project will allow global firms to properly value their investments, often for the first time, and we envision it changing the state of play across the commodity finance sector,” Samuelrich says.

Commodity producers can face significant financial risks if they do not accurately incorporate sustainability risks into their business models, says Green Century. Not paying attention to sustainability issues can lead to inefficient land use and high carbon emissions, resulting in opportunity costs and carbon taxes or fines.

The forest protection project will help investors and financial institutions value risks inherent in unsustainable commodity supply chains by providing 40 reports over the next five years. The three sponsoring organizations will conduct the research and Green Century will handle the outreach to U.S. and global investment firms.

Green Century Capital Management is the investment advisor to the Green Century Funds and offers two environmentally and socially responsible funds, the Green Century Equity Fund and the Green Century Balanced Fund.
