Global Greenhouse Gas Emissions by Economic sector (based on global emissions from 2010)

Question

Economic Sector Industry Transportation Buildings Agriculture, Forestry, and Other Land Use Electricity and Heat Production Other Energy Production
Percentage of global greenhouse emissions
\[21\%\]
\[14\%\]
\[6\%\]
\[24\%\]
\[25\%\]
\[10\%\]

Greenhouse gas emissions can be analyzed by the economic activities that produce them. In 2014, The United Nations Intergovernmental Panel on Climate Change (IPCC) completed its fifth report, which included a breakdown of global emissions by economic sector, using global emissions data from 2010. Based on the data, the authors claim that electricity and heat production, which entails the burning of coal, natural gas, and oil, is the largest source of greenhouse gas emissions.
Which choice best describes data from the table that supports the researchers’ claim?

A
In 2010, electricity and heat production was responsible for 25% of global greenhouse gas emissions, the most of any sector.
(Choice B) In 2010, industry was responsible for just over 20% of global greenhouse gas emissions.
B
In 2010, industry was responsible for just over 20% of global greenhouse gas emissions.
(Choice C) In 2010, transportation generated significantly more greenhouse gas emissions than buildings did.
C
In 2010, transportation generated significantly more greenhouse gas emissions than buildings did.
(Choice D) In 2010, the production of energy other than electricity and heat generated around 10% of global greenhouse gas emissions.
D
In 2010, the production of energy other than electricity and heat generated around 10% of global greenhouse gas emissions.

Answer 1

The choice that best supports the researchers’ claim that electricity and heat production is the largest source of greenhouse gas emissions is:

(Choice A) In 2010, electricity and heat production was responsible for 25% of global greenhouse gas emissions, the most of any sector.

This directly indicates that electricity and heat production contributed the highest percentage compared to other sectors listed.
