Kyoto Protocol Emissions Targets:

The Kyoto Protocol is an international treaty that commits its Parties to reduce greenhouse gas emissions, based on the scientific consensus that global warming is occurring and that human-made CO2 emissions are driving it.

1. Binding Targets for Developed Countries: The Kyoto Protocol established legally binding emissions reduction targets specifically for developed countries, known as Annex I countries. These targets required these countries to reduce their collective greenhouse gas emissions by an average of 5.2% below 1990 levels during the first commitment period (2008-2012).

2. Differentiated Responsibilities: The principle of "common but differentiated responsibilities" underpins the Kyoto Protocol. This principle recognizes that developed countries have historically contributed the most to greenhouse gas emissions and thus have a greater responsibility to lead in emissions reduction efforts.

3. Voluntary Participation for Developing Countries: Developing countries, referred to as non-Annex I countries, were not subject to binding emissions reduction targets under the Kyoto Protocol. Their participation in emissions reduction efforts was voluntary, reflecting their lower historical contribution to global emissions and their need for economic development.

Kyoto Protocol Overview: The CFA Institute explains that the Kyoto Protocol's binding targets apply only to developed countries, with the aim of addressing climate change through legally mandated emissions reductions.

Principle of Differentiated Responsibilities: This principle is highlighted in the CFA curriculum as a fundamental aspect of international climate agreements, ensuring that countries' responsibilities are aligned with their contributions to the problem and their capacity to address it.

In conclusion, the Kyoto Protocol established emissions targets that are binding only on developed countries, making option C the verified answer.
