CES CES Climate Change & Greenhouse Gas Management 2

Question 1

Which international agreement succeeded the Kyoto Protocol as the primary global framework for addressing climate change, adopted in 2015?

Accepted Answer

Paris Agreement

Answer

The Paris Agreement, adopted in December 2015 under the UNFCCC, set the goal of limiting global warming to well below 2°C above pre-industrial levels.

Question 2

In greenhouse gas accounting, which 'scope' refers to indirect emissions from the generation of purchased electricity consumed by a company?

Accepted Answer

Scope 2

Answer

Scope 2 emissions are indirect GHG emissions associated with the purchase of electricity, steam, heat, or cooling, as defined by the GHG Protocol Corporate Standard.

Question 3

Which process is responsible for the largest natural flux of CO2 from terrestrial ecosystems to the atmosphere?

Accepted Answer

Soil and ecosystem respiration

Answer

Soil and ecosystem respiration (decomposition of organic matter plus plant respiration) is the largest natural terrestrial flux of CO2 back to the atmosphere.

Question 4

What does the term 'radiative forcing' measure in climate science?

Accepted Answer

The change in energy flux in the atmosphere caused by a climate driver

Answer

Radiative forcing measures the change in energy flux (W/m²) in the atmosphere resulting from a climate driver such as increased GHG concentrations, quantifying its warming or cooling effect.

Question 5

Under the Clean Air Act, which EPA rule first required large stationary sources to obtain permits for greenhouse gas emissions?

Accepted Answer

Tailoring Rule

Answer

The EPA's 2010 Tailoring Rule established thresholds for GHG emissions that trigger Prevention of Significant Deterioration (PSD) and Title V permit requirements under the Clean Air Act.
