CAP Emissions Reduction Strategies 3

Question 1

Which energy efficiency strategy involves recovering waste heat from industrial exhaust streams to generate electricity or preheat process inputs?

Accepted Answer

Waste heat recovery (WHR) systems

Answer

Waste heat recovery systems capture thermal energy from exhaust gases, cooling water, or other waste streams to improve overall energy efficiency and reduce fuel combustion needs.

Question 2

Under Science Based Targets initiative (SBTi) Corporate Net-Zero Standard, companies must reduce value chain emissions by at least what percentage before using neutralization (offsets)?

Accepted Answer

90% across all Scopes by target year

Answer

SBTi Net-Zero Standard requires companies to reduce Scope 1, 2, and 3 emissions by at least 90% before using carbon removal to neutralize residual emissions.

Question 3

A commercial building operator replaces T12 fluorescent lamps with LED fixtures, reducing lighting energy consumption by 60%. This measure primarily affects which category of GHG emissions?

Accepted Answer

Scope 2 indirect emissions from purchased electricity

Answer

Reducing electricity consumption from the grid lowers Scope 2 indirect emissions associated with purchased energy.

Question 4

What is the primary mechanism by which reforestation projects generate carbon credits under REDD+ programs?

Accepted Answer

Carbon sequestration by growing trees that absorb atmospheric CO2

Answer

Reforestation creates carbon sinks as growing trees absorb CO2 from the atmosphere through photosynthesis and store it in biomass and soil.

Question 5

Which refrigerant transition strategy involves replacing high-GWP HFCs with natural refrigerants like CO2 (R-744) or ammonia (R-717)?

Accepted Answer

Low-GWP natural refrigerant conversion

Answer

Transitioning to natural refrigerants such as CO2 (GWP=1) or ammonia (GWP=0) dramatically reduces the climate impact of refrigerant leaks compared to HFCs with GWPs of 1,000–4,000.
