Imagine a world with only two countries, Country A and Country B. Both countries would benefit from a cleaner global atmosphere. Country A is considering investing heavily in new, expensive technology to significantly reduce its carbon emissions. Country B is not planning any such investment. Based on the characteristics of this situation, what is the most likely economic challenge that will arise?

The Economist's View on Climate Action

The Challenge of International Climate Agreements

The reduction of atmospheric carbon dioxide is often described using a specific economic framework. Match the key characteristics of this framework to their real-world manifestations in the context of global climate action.

True or False: If a single, wealthy nation successfully develops and implements technology that removes a significant amount of carbon dioxide from the atmosphere, it can effectively charge other nations for the resulting climate benefits because the positive effects can be restricted to only those countries that contribute financially.

Cost-Benefit Analysis of National Climate Action

A key challenge in securing global action on climate change is that while the costs of reducing emissions are borne by individual countries, the benefits are diffused globally. This mismatch, where benefits are both non-excludable and _________, often leads to a collective action problem.

Several countries are debating strategies to address the issue of atmospheric carbon dioxide, where the benefits of one country's reduction efforts are shared by all. Considering the economic incentives at play in such a situation, which of the following proposed strategies is most likely to fail in achieving its goals due to the underlying nature of the problem?

A group of nations convenes to address the shared problem of a changing global climate. From an economic perspective focused on the incentives each nation faces, arrange the following events into the most likely logical sequence.
