Climate Change Mitigation Plans 2

Question 1

Which international framework established nationally determined contributions (NDCs) as the primary mechanism for country-level climate mitigation commitments?

Accepted Answer

Paris Agreement

Answer

The 2015 Paris Agreement introduced NDCs, requiring each signatory nation to set and update its own emission reduction targets.

Question 2

A city wants to cut transportation emissions fastest. Which mitigation strategy typically delivers the largest near-term reduction?

Accepted Answer

Mandating electric buses on all routes

Answer

Electrifying bus fleets removes direct tailpipe emissions from high-frequency, high-ridership routes, providing the largest fleet-wide impact quickly.

Question 3

What does 'carbon neutrality' require that simple 'emissions reduction' does not?

Accepted Answer

Offsetting or removing remaining emissions to reach net zero

Answer

Carbon neutrality means balancing residual emissions with equivalent removals or offsets, whereas reduction alone still allows a net positive output.

Question 4

Which sector is the largest source of US greenhouse gas emissions as of recent EPA inventories?

Accepted Answer

Transportation

Answer

Transportation overtook electricity generation as the top US GHG sector, driven by cars, trucks, and aviation burning petroleum fuels.

Question 5

Afforestation differs from reforestation in that afforestation involves:

Accepted Answer

Planting trees on land that was not previously forested

Answer

Afforestation creates new forests on land historically used for other purposes, while reforestation restores previously forested areas.
