The chart can help answer questions regarding the source of electricity generation, types of industries responsible for greenhouse gas emissions, the reason for agriculture being the largest source of emissions, and the dip in greenhouse gas emissions in transportation after 2007.

Which source of electricity generation caused the most emissions?

To determine which source of electricity generation caused the most emissions, you can refer to the chart. Look at the sector with the highest bar on the graph to identify the source that contributed the most to greenhouse gas emissions.

What types of industries are responsible for greenhouse gas emissions?

To determine the types of industries responsible for greenhouse gas emissions, examine the different sectors represented by different colors on the chart. Each color represents a different industry, so you can match the color to the legend to identify the industries.

Why is agriculture the largest source of greenhouse gas emissions?

Agriculture is the largest source of greenhouse gas emissions because it produces methane and nitrous oxide, which are potent greenhouse gases. Livestock farming, rice cultivation, and the use of chemical fertilizers are some examples of agricultural practices that contribute to these emissions.

What caused the dip in greenhouse gas emissions in transportation after 2007?

The dip in greenhouse gas emissions in transportation after 2007 can be attributed to various factors, such as the introduction of fuel efficiency standards, the use of cleaner fuels, and shifts towards alternative transportation modes like electric vehicles and public transportation.

The probable chart to this question is assigned below.
