Portland, OR - Global mutual fund Portfolio 21 today announced its Top 10 financial performers among environmentally sustainable companies. The top performers in the fund posted returns ranging from 52% to 120% in 2005. Portfolio 21 invests in 80 companies selected from among 2,000 companies based in 16 countries, including the United States. It selects only those companies with an explicit commitment to sustainable business practices such as energy and resource efficiency, minimizing ecological impacts of products and reducing greenhouse gas emissions.

"If you are a savvy investor interested in a good return, you need to pay attention to ecological trends and how they affect the bottom line," said Carsten Henningsen, co-founder of Portfolio 21. "Global warming will have an enormous impact on the global economy in the coming years; companies that are already addressing the risks and opportunities presented by climate change have a big head start."

More than 70 percent of the world's largest 500 companies (FT 500) are now addressing climate change in their corporate reporting, according to the Carbon Disclosure Project. In addition, 90 percent of those companies flagged climate change as posing commercial risks and/or opportunities to their business.

"There is mounting evidence that failure to respond to the business risks associated with climate change could result in multi-billion dollar losses for U.S. businesses and investment portfolios," said John Harrington, CEO of Harrington Investments and author of The Challenge To Power: Money, Investing and Democracy. "In addition, companies that take proactive measures to address climate risk enjoy lower costs, higher profit margins and enhanced customer loyalty. With companies outside the U.S. already taking a leading role in reducing greenhouse gas emissions, American companies face a 'sustainability gap' that could affect their competitive edge."

Portfolio 21's Top 10 financial performers for the 12-month period ending Dec. 30, 2005, include:

Energy Conversion Devices: ECD develops products for the fields of alternative energy, electronic components and storage devices -- products include thin-film solar cells, energy storage (batteries), hydrogen storage and information technologies. ECD innovations include the technology for rewritable CDs and a new solar roof cell system. 2005 performance: 120%

JM: This Swedish construction and real estate company leads its industry in sustainable practices. The company's commitment to improvement ranges from the energy efficiency of the buildings it develops, to the direct CO2 emissions associated with its operations, to the number of building products in its environmental database. 2005 performance: 84%

Atlas Copco: As a manufacturer of industrial machinery and pneumatic tools, Sweden's Atlas Copco makes products for industries with significant environmental impacts. In designing its products the company strives to reduce lifecycle impacts by improving the environmental performance of every product design. With approximately 21% of revenues from its tool rental business, Atlas ensures reuse of its products and has programs to recycle tools when they reach the end of their useful life. 2005 performance: 77%

Whole Foods Market With a wide range of certified organic produce, food products, and coffee grown without the use of synthetic fertilizers, pesticides or herbicides, WF supports the organic industry and local farmers.
