Final answer:
The first international agreement on climate change was the a. Kyoto Protocol, established in 1997 to legally commit participating countries to reduce greenhouse gas emissions.
Step-by-step explanation:
The name of the first international agreement on climate change was the Kyoto Protocol. It was developed in 1997 in Kyoto, Japan, as a result of the United Nations Framework Convention on Climate Change (UNFCCC). The Protocol created a legal commitment for participating countries to reduce greenhouse gases in an attempt to address climate change issues. However, the enforcement of the Kyoto Protocol was a subject of debate and not all countries ratified it.
The United States and China, two significant contributors to global emissions, did not commit to the Protocol for various reasons, including economic concerns and the potential impact on growth. While some individual countries met and exceeded their goals for reducing emissions, the global effort was not as successful as hoped. Nevertheless, the Kyoto Protocol marked a significant step in international climate negotiations, which paved the way for subsequent agreements like the Paris Climate Agreement of 2015.
