What was the purpose of the UNFCCC on Climate Change? to reduce the emission of carbon dioxide to phase out the production of halocarbons to reduce the emission of the greenhouse gas methane to develop a framework for future agreements on climate change

The purpose of the UNFCCC (United Nations Framework Convention on Climate Change) was **to develop a framework for future agreements on climate change**. While the other options relate to *goals* within that framework (reducing greenhouse gas emissions like carbon dioxide and methane, phasing out harmful substances like halocarbons), the UNFCCC itself was the overarching treaty that established the international process for addressing climate change. It set the stage for later agreements like the Kyoto Protocol and the Paris Agreement, which aimed to implement specific actions.<br />
