Many countries emit large amounts of greenhouse gases with the United States and Russia being the largest offenders. World leaders hold summits every 5 years to discuss climate concerns over the impact of greenhouse gasses. The Rio summit 1992 made way for agreements to be reached in 1997 at the Kyoto meeting where all attending countries agreed to reduce carbon emissions. Although the United States had agreed to reduce emissions, implementation was stalled due to the senate not ratifying the agreement. By the Johannesburg summit of 2002 the world audience was already making vilifying statements about the Americans searching for loopholes in the Rio agreement. Currently the United States and other nations are working toward a revised plan to address greenhouse gasses. In the current strategy, developing nations would be allowed an increase in current carbon emissions while developed countries will implement plans that reduce theirs.

u didnt mentioned anything about Rio. So there was really no point of having it . But if you do have info on Rio add it back in and make a paragraph explaining about Rio. then, if u make a closing paragraph , you would have your self a 5 paragraph essay ..

hows this?:

Many countries are very bad offenders, especially when it comes to greenhouse gas emissions in the United States and Russia. Due to this and to many other climatic and diplomatic reasons, the world summits are held every five years. Kyoto’s world summit was last held in 1997, and most recently was the Johannesburg summit which was held in 2002.

In the Kyoto summit in 1997 an agreement was decided upon, in this pact all the countries that attended and agreed to reduce carbon emissions. Although they had signed up to it, the Americans could not ratify the agreement and come together as one in Kyoto because the senate would not pass it.

By the times of the Johannesburg summit in 2002, the Americans were being vilified by the world press as they were now trying to go back to the agreement that they all signed and tried to find loopholes. The U.S.A. and other nations tried their best to put forward the idea of convergence or coming closer. This idea stated that the developing world would be allowed to increase their carbon emissions and then the developed world would reduce theirs.

hope this helps.
