Answer
Brief Explanations:
The Kyoto Protocol aimed to reduce greenhouse - gas emissions. Developed countries taking on a bigger share of limits led to positive changes in pollution levels worldwide as it was a step towards global environmental protection. The other options are not direct results of developed countries taking on more limits under the Kyoto Protocol. China was not the leading producer of carbon - dioxide emissions as a result of this, and neither Canada became the world leader in lowered pollution levels, nor did it lead to an increase in developing countries' participation in that context.
Answer:
positive changes in the pollution levels worldwide
