After some analysis and investigation into the information provided by gapminder.org, we highlighted the countries whose total sulfur emissions were greater than 1000 kilotonnes in 1989, the year the Montreal Protocol went into effect. We then noted the reported numbers for the year 2000, which is the most recent data year available on Gapminder, in order to determine any signficant changes to the same country's total sulfur emissions.
A relationship that we recognized from the countries selected is that the sulfur emissions of those who were still developing countries at the time continued to increase after the Montreal Protocol. This includes Brazil, Chile, India, Kazakhstan, and Mexico, as well as South Africa although minutely. This relationship is not surprising given the fact that these countries don't have the necessary advancements and technological services available to them that developed countries have at their disposal in order to reduce their sulfur emissions accordingly.
