One of the most intimidating parts of AP Environmental Science is memorizing the long list of environmental laws, treaties, and acts. You’re expected to know names, purposes, and sometimes the year of enactment for each. On the APES exam, these can appear in multiple-choice questions or as part of an FRQ.
In this RevisionDojo guide, we’ll break down how to efficiently memorize environmental laws so they stick in your long-term memory—without cramming the night before.
Step 1 – Know Which Laws to Focus On
The College Board doesn’t publish an official master list, but these commonly appear:
- Clean Air Act (CAA) – Regulates air emissions and pollutants.
- Clean Water Act (CWA) – Restores and maintains water quality.
- Endangered Species Act (ESA) – Protects threatened and endangered species.
- National Environmental Policy Act (NEPA) – Requires Environmental Impact Statements (EIS).
- Safe Drinking Water Act (SDWA) – Ensures safe public drinking water.
- Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA/Superfund) – Cleans up hazardous waste sites.
- Resource Conservation and Recovery Act (RCRA) – Governs hazardous waste disposal.
- Kyoto Protocol – International treaty reducing greenhouse gases.
- Paris Agreement – Global climate change mitigation agreement.
Step 2 – Use Acronyms to Group Laws
Creating acronyms helps you remember related laws:
- Clean Acts – CAA and CWA.
- Species & Nature – ESA and NEPA.
