<h1>GHG emissions in the world in 2012<h1/>

<p>Countries are ranked by total greenhouse gases (GHG) emissions (tonnes of CO2 equivalent), and per capita (thousand kgs). Based on <a href="https://stats.oecd.org/">OECD data.<a/></p>

<p>Overall, we can see that the United States are far away from the others, and Australia has a high level of greenhouse gas emissions per person, but a low total emissions. </p>
