What is the main objective of the UN's annual climate change conference (COP)?

The main objective of the UN's annual climate change conference, known as the Conference of the Parties (COP), is to review the implementation of the United Nations Framework Convention on Climate Change (UNFCCC) and to negotiate climate action among member countries. This conference serves as a platform for countries to discuss and evaluate the progress made towards achieving their climate goals, sharing best practices, and forging new agreements to combat climate change effectively.

During the COP, representatives from nations come together to address pressing climate issues, negotiate commitments for reducing greenhouse gas emissions, and enhance efforts to adapt to the impacts of climate change. This collaborative approach is crucial as climate change is a global issue that transcends national boundaries, requiring collective action from all countries involved.

The other options, while they touch on various aspects of international cooperation and development, do not pertain directly to the core mission of the COP. The focus of the conference is squarely on climate change mitigation and adaptation, making option B the correct choice.
