設立於巴黎的經濟合作與發展組織（OECD）發表報告，回顧美國近十年來的環境進程並歸結出，美國在處理全球環境議題上有責任擔任更為積極之角色。評鑑小組指出，美國在推動環境和人體健康之保護的同時，也需採取對水資源和能源的有效管理及利用，以保持經濟繁榮。
OECD乃是由30個國家組成的論壇，在此合作架構下，各民主政體共同合作，因應全球化之下的經濟、社會和環境議題。自此計畫開始以來，所有成員國皆已受過兩次評鑑。
此次評鑑報告，是根據OECD評鑑小組在2004年至美國進行為期兩週、700場以上的訪談，評估了美國如何管理空氣品質、水源和生物多樣性議題，以及美國如何整合環境議題與經濟、財政政策；評估報告呈現出美國在達成國際環境承諾上的具體成果。
評鑑小組在報告中指出，在處理氣候變遷、生物多樣性和有毒化學物質等全球環境議題上，美國需要展現更強的領導作為。OECD說，儘管過去10年來某些地區的環境議題有所進展，但仍有諸多地區需要投注更多力量。
整體來說，OECD在這份報告中呼籲美國應強化環境管理效率與能源使用效能，OECD並說，這個方向最終將有助於經濟。
The United States needs to play "a more proactive role in dealing with global environmental concerns," finds a 10 year review of U.S. environmental progress by the Organization for Economic Cooperation and Development (OECD) based in Paris. The review team says the United States also need to make more efficient use of energy and water to safeguard economic prosperity while protecting the environment and human health.
The OECD is a 30 nation forum in which democracies work together to address economic, social and environmental challenges of globalization. All member nations have been evaluated twice since the program began.
The review evaluates the ways in which the U.S. manages air quality, water resources and biodiversity and how it integrates environmental concerns into economic and fiscal policies. Based on more than 700 interviews conducted by OECD's review team during a two week visit to the United States in 2004, it assesses how well the country meets its international environmental commitments.
In its report, the review team indicates a need for greater U.S. leadership in addressing global environmental concerns on climate change, biodiversity and toxic chemicals. Despite progress in some areas over the past decade, more effort is needed in others, the OECD said.
Overall, the OECD report urges the United States to increase the efficiency of its environmental management and energy use, projecting that doing so would yield economic benefits.
