NPPE Environmental and Social Responsibilities 5

Question 1

Which international agreement, adopted in 2015, sets binding targets for signatory nations to limit global average temperature rise and requires periodic nationally determined contributions (NDCs)?

Accepted Answer

Paris Agreement

Answer

The Paris Agreement (2015) requires countries to submit and regularly update NDCs and aims to limit warming to 1.5–2°C above pre-industrial levels.

Question 2

In the context of ISO 14001, what does the Plan-Do-Check-Act (PDCA) cycle most directly support?

Accepted Answer

Continual improvement of an organization's environmental management system

Answer

ISO 14001 uses the PDCA cycle as its framework to ensure organizations continually improve their environmental management systems.

Question 3

When evaluating a proposed industrial facility near a sensitive receptor such as a school, what is the primary tool used to predict ground-level air pollutant concentrations?

Accepted Answer

Atmospheric dispersion modeling

Answer

Atmospheric dispersion models (such as EPA's AERMOD) predict how pollutants spread in the atmosphere to estimate concentrations at sensitive receptor locations.

Question 4

A structural engineer proposes using recycled steel instead of virgin steel for a bridge project, reducing embodied carbon by 40%. This decision is best described as an example of which sustainability strategy?

Accepted Answer

Material substitution to reduce upstream environmental impact

Answer

Using recycled materials instead of virgin ones reduces the embodied carbon associated with raw material extraction and processing, a classic material substitution strategy.

Question 5

Under the Resource Conservation and Recovery Act (RCRA), which designation triggers the most stringent federal hazardous waste regulations for generators?

Accepted Answer

Large Quantity Generator (LQG)

Answer

Large Quantity Generators (those generating ≥1,000 kg of hazardous waste per month) face the most comprehensive RCRA compliance requirements.
