Are high CO2 emitters less intensely concerned about climate change?

The scatter chart below shows the relationship between a country’s concern for climate change and the amount of CO2 it emits per capita. The original source  zooms in and limits the y-axis between 8 and 12 on the climate change concern index. As result, it visually suggests a relatively strong correlation that high CO2 emitting countries are less concerned with climate change. Displaying the entire working range of the y-axis still suggests this correlation but it is less visually strong (note that lowest value concern index possible is 3).

The scatter chart was built using with PowerPoint using the Aploris charts add-in. Data provided by Pew Research Center.

Mekko chart highlighting fresh water use across different countries

The Mekko chart below shows use of fresh water across several countries per year. The width of each column indicates the amount of water used by a specific country and the height indicates the share used by a sector. The area of each segment is proportional to the water used by the corresponding sector and country. Most of the fresh water is used from agricultural needs and India uses the largest amount.

Area chart showing US energy consumption over the last 50 years

The area chart below shows US energy consumption by source between 1960 and 2014. Unlike the line chart, the area chart shows the cumulative impact allowing the reader to better ascertain the contribution of each source to the total energy consumption.  While renewable energy sources have grown rapidly in recent years, fossil fuel still dominates US consumption.

Global greenhouse gas emissions plotted in bar-mekko

The bar-mekko chart below is a variant of the Marimekko chart. It shows global greenhouse gas emissions by continents.

Each region’s population is displayed by the width of each column. The population of a continent is therefore proportional to its range on the x axis. The column labels also include the population data. The height of each column in a column shows the amount of emitted greenhouse gases per capita. With this data representation the area of each segment is proportional to the total amount of a continent’s greenhouse gas emissions.

Colored segments are used to differentiate between different types of greenhouse gases. Because some the of segments were small, a legend is used. For cleanliness, the labels for smaller segments were excluded.

Bar mekko chart showing greenhouse gas emissions for 5 largest US states

The mekko chart, or specifically the bar-mekko chart, below shows greenhouse gas emissions for the 5 largest US states.

The width of each column is proportional the state’s population.  The column labels also include the population data.  The height of each segment in a column represents metric tons per capita emitted for each type of greenhouse gas.  Because some the of segments were small, a legend is used.  For cleanliness, the labels for smaller segments were excluded.  In addition, this mekko chart has visible x and y axes.
