Very interesting class.

Only one comment : it is becoming difficult to answer to questions. Indeed, they are referring to 2014 datas that are getting harder to get and links that can't be found anymore.

Great course! However sadly, some of the links to the questions in some of the partial exams (at least 2) are not available anymore/the data has been changed, and this affects directly in the score of the exams, which is a little unfair in my opinion. It would be great to have an updated (2018) version of this course. Thank you Professor Jeffrey Sachs for continue to inspiring our generation to be the Sustainable Development generation.

The Prof knows a lot, just a little bit boring=)

A comprehensive course, with lots of good data supporting the units, however the homework is challenging as many of the links no longer work or data sets have been updated since the course was first posted, making it hard to answer the questions.

For the quizes - some of the questions are out of date with the website links/data is not readily available.

This course have been very informative, engaging, practical and utmost importance for our future survival. I learnt a lot of important concepts regarding sustainability of our human race.

My experience was exceptiiona;

This is a very complete course if you are interested to learn about Sustainable Development from the beginning. You will start understanding why the economy, society and environment, always joined to a good government of our countries; are the key to reach the balance of our civilization future.

If there was certificate associated with this course, I must have clicked on 5 stars.

Great course taught by a brilliant economist.
