I'd like you to put yourself in the shoes of a manager of a cement plant. From this viewpoint I'd like you to consider the concept of 'negative externalities' taking CO2 emissions as an example. Record a short video that explains your position on this issue.

I'll be endorsing particularly good answers. Good luck!

Task: From the viewpoint of a cement plant manager, record and submit a short video in which you explain the concept of 'negative externalities' taking CO2 emissions as an example and why it is difficult to tackle in absence of a system such as the European cap-and-trade system of emission rights.

Now I'd like you to consider in more detail the EU Emissions Trading Scheme (ETS).

Task: Please submit a description of the ETS that explains how it reduces CO2 emissions, further explain the main drawback of the scheme.

How does the EU ETS tackle the problem of CO2 emissions? What has been its main drawback?
