Do people in red-leaning or blue-leaning states have a bigger carbon footprint?

Just looking at data from the Energy Information Administration from 2014, it looks like red states do produce more CO₂ per capita:

 

I wanted to better quantify this, though, so I ran the data through a Pearson correlation calculator.* Here’s the dataset in case you’d like to check my work:

And, here are the results:

As you can see, mathematically, as the proportion of a state that was Republican or leaned Republican in 2014 went up, so did the state’s per capita CO₂ emissions. The value of R is 0.549, a moderate positive correlation. R²: 0.3014.

For the sake of thoroughness, I performed the same calculation for the Democrats. Here’s that dataset:

Here’s the resultant graph:

The value of R is -0.5593, a moderate negative correlation. R²: 0.3128.
