CAP Emissions Reduction Strategies 4

Question 1

Which agricultural emission reduction practice involves applying nitrification inhibitors to reduce N2O emissions from fertilized soils?

Accepted Answer

Controlled-release fertilizer with nitrification inhibitors

Answer

Nitrification inhibitors slow the bacterial conversion of ammonium to nitrate, reducing the substrate available for denitrification that produces N2O.

Question 2

In the context of carbon markets, what is 'additionality' for an emission reduction project?

Accepted Answer

The emission reduction would not have occurred without the carbon finance incentive

Answer

Additionality requires that the emission reductions are beyond what would have happened under a business-as-usual scenario without carbon market revenue.

Question 3

A utility company installs grid-scale battery storage to increase renewable energy utilization and reduce curtailment. What is the primary emissions benefit?

Accepted Answer

Enables dispatch of stored renewable energy during peak demand, displacing fossil fuel peaker plants

Answer

Battery storage allows excess renewable generation to be stored and dispatched during high-demand periods, replacing high-emission natural gas peaker plant output.

Question 4

What distinguishes a 'market-based' Scope 2 accounting method from a 'location-based' method?

Accepted Answer

Location-based uses the national average grid emission factor; market-based uses contractual instruments like RECs

Answer

The location-based method applies average grid emission factors, while the market-based method reflects contractual claims from instruments like renewable energy certificates (RECs) or power purchase agreements (PPAs).

Question 5

Which industrial decarbonization technology captures CO2 directly from point sources such as power plant flue gas before it is released to the atmosphere?

Accepted Answer

Carbon capture and storage (CCS) at point source

Answer

Point-source CCS captures CO2 from concentrated industrial or power generation flue gas streams and transports it for geological storage, preventing atmospheric release.
