CES CES Climate Change & Greenhouse Gas Management

Question 1

Which greenhouse gas has the highest global warming potential (GWP) over a 100-year timeframe among those regulated under the Kyoto Protocol?

Accepted Answer

Sulfur hexafluoride (SF6)

Answer

Sulfur hexafluoride (SF6) has a GWP of approximately 23,500 over 100 years, making it the most potent of the six Kyoto Protocol greenhouse gases.

Question 2

Under the EPA's Greenhouse Gas Reporting Program (GHGRP), facilities emitting at or above what annual threshold (in metric tons CO2 equivalent) must report?

Accepted Answer

25,000

Answer

The GHGRP requires facilities emitting 25,000 metric tons CO2e or more per year to report their emissions to the EPA.

Question 3

Which of the following best describes the concept of 'carbon sequestration' in environmental science?

Accepted Answer

The process of capturing and storing atmospheric CO2 to mitigate climate change

Answer

Carbon sequestration refers to the long-term capture and storage of atmospheric CO2 in forests, soils, oceans, or geological formations to reduce greenhouse gas concentrations.

Question 4

The Intergovernmental Panel on Climate Change (IPCC) assessment reports are produced by which type of organization?

Accepted Answer

A United Nations body that synthesizes scientific literature on climate change

Answer

The IPCC is a UN body established in 1988 by UNEP and WMO that synthesizes existing peer-reviewed scientific literature to assess climate change science, impacts, and mitigation options.

Question 5

Which sector is typically the largest contributor to US greenhouse gas emissions?

Accepted Answer

Transportation

Answer

Transportation has been the largest source of US GHG emissions since 2016, primarily from burning fossil fuels in cars, trucks, ships, trains, and planes.
