EPA 的使命是保护人类健康和环境。

EPA 致力于确保：

• 美国拥有洁净的空气、土地和水；
• 国家降低环境风险的努力以现有的最佳科学信息为基础；
• 保护人类健康和环境的联邦法律得到公正、有效的管理和执行，并符合国会的意图；
• 环境管理是美国有关自然资源、人类健康、经济增长、能源、交通、农业、工业和国际贸易政策不可或缺的一部分，在制定环境政策时同样会考虑这些因素；
• 社会各个阶层——社区、个人、企业以及州、地方和部落政府——都能获得足够的准确信息，以有效参与管理人类健康和环境风险；
• 受污染的土地和有毒场所由潜在责任方清理并恢复生机；
• 市场上的化学品都经过安全审查。

为了完成这一使命，我们：

制定并执行法规

当国会制定环境法时，我们会通过制定法规来实施。通常，我们会制定国家标准，各州和部落会通过自己的法规来执行。如果他们达不到国家标准，我们可以帮助他们。我们还会执行我们的法规，并帮助公司了解要求。

提供补助金

我们预算的近一半用于资助州环保项目、非营利组织、教育机构等。这些资金用于各种各样的项目，从帮助我们做出决策的科学研究到社区清理。总的来说，资助帮助我们实现了我们的总体使命：保护人类健康和环境。

研究环境问题

我们在全国各地的实验室中发现并尝试解决环境问题。为了了解更多信息，我们与其他国家、私营部门组织、学术机构和其他机构共享信息

Our Mission and What We Do

Our Mission

The mission of EPA is to protect human health and the environment.

EPA works to ensure that:

• Americans have clean air, land and water;
• National efforts to reduce environmental risks are based on the best available scientific information;
• Federal laws protecting human health and the environment are administered and enforced fairly, effectively and as Congress intended;
• Environmental stewardship is integral to U.S. policies concerning natural resources, human health, economic growth, energy, transportation, agriculture, industry, and international trade, and these factors are similarly considered in establishing environmental policy;
• All parts of society--communities, individuals, businesses, and state, local and tribal governments--have access to accurate information sufficient to effectively participate in managing human health and environmental risks;
• Contaminated lands and toxic sites are cleaned up by potentially responsible parties and revitalized; and
• Chemicals in the marketplace are reviewed for safety.

To accomplish this mission, we:

Develop and enforce regulations

When Congress writes an environmental law, we implement it by writing regulations. Often, we set national standards that states and tribes enforce through their own regulations. If they fail to meet the national standards, we can help them. We also enforce our regulations, and help companies understand the requirements.

Give grants

Nearly half of our budget goes into grants to state environmental programs, non-profits, educational institutions, and others. They use the money for a wide variety of projects, from scientific studies that help us make decisions to community cleanups. Overall, grants help us achieve our overall mission: protect human health and the environment.

Study environmental issues

At laboratories located throughout the nation, we identify and try to solve environmental problems. To learn even more, we share information with other countries, private sector organizations, academic institutions, and other agencies.
