Question 1

The U.S. National Environmental Policy Act (NEPA) requires federal agencies to:

Accepted Answer

Prepare an Environmental Impact Statement (EIS) for major federal actions significantly affecting the environment

NEPA (1970) mandates Environmental Impact Statements for significant federal actions, ensuring environmental consequences are analyzed before decisions are made.

Question 2

The precautionary principle in environmental policy states that:

Accepted Answer

When an action risks serious harm, precautionary measures should be taken even if full scientific certainty is lacking

Answer

The precautionary principle shifts the burden of proof: protective action should be taken in the face of scientific uncertainty when potential harm is serious or irreversible.

Question 3

Command-and-control environmental regulation differs from market-based instruments in that:

Accepted Answer

Command-and-control sets specific standards or bans; market-based instruments use prices or permits to achieve goals

Answer

Command-and-control regulation specifies what technology to use or sets emission limits; market-based tools like carbon taxes or cap-and-trade use economic incentives.

The Kyoto Protocol differed from the Paris Agreement primarily in that:

Accepted Answer

Kyoto covered only developed (Annex I) countries with binding targets; Paris requires all nations to submit nationally determined contributions

Answer

Kyoto (1997) set legally binding emission reduction targets for developed nations only; Paris (2015) includes all parties but uses nationally determined contributions (NDCs) that are not legally binding targets.

Accepted Answer

A permit system (NPDES) controlling discharges from point sources to navigable waters

The Clean Water Act's National Pollutant Discharge Elimination System (NPDES) requires permits specifying allowable discharge levels for point sources (pipes, outfalls).
