Climate Change Mitigation Plans 3

Question 1

Demand-side mitigation strategies focus primarily on:

Accepted Answer

Changing consumer behavior and reducing consumption

Answer

Demand-side measures target how people live, eat, travel, and purchase goods, reducing emissions at the point of consumption rather than production.

Question 2

Which greenhouse gas has a much shorter atmospheric lifetime than CO₂ but a far higher 20-year warming potential, making rapid reduction especially impactful?

Accepted Answer

Methane

Answer

Methane persists roughly 12 years but warms the climate about 80 times more than CO₂ over 20 years, so cutting it yields fast near-term benefits.

Question 3

An emissions trading scheme (cap-and-trade) controls total emissions by:

Accepted Answer

Setting an overall cap and letting firms buy and sell allowances

Answer

Cap-and-trade sets a ceiling on total allowed emissions and issues tradable permits, letting the market find the cheapest ways to reduce pollution.

Question 4

Why is building energy efficiency often called a 'first fuel' in mitigation strategies?

Accepted Answer

Saved energy is the cheapest and cleanest energy source

Answer

Energy not consumed avoids both cost and emissions, making efficiency improvements the lowest-cost mitigation option before adding any new supply.

Question 5

The 'just transition' principle in climate mitigation planning specifically addresses:

Accepted Answer

Ensuring workers in fossil fuel industries are not left behind economically

Answer

Just transition frameworks pair decarbonization with retraining, social support, and economic development to protect communities dependent on fossil fuel jobs.
