It was a very challenging and tough course. But I am not able to access the purchase certificate option.

I cannot overstate the valuable insights and historical and societal information brought by this course!

Excellent materials and outstanding lecture by Prof. Sachs. A very inspirational and eye opening course

A class every one should take, as important facts are presented and explained, sustainability is a must

That was in intense and a very exclsive course with the invaluable contribution of the course lecturer.

Course was an excellent. It was exciting too. How can I receive/purchase course completion certificate?

I love how Sachs has given a comprehensive overview of all aspects of development. I LOVE this course!

Excellent Overall view of How we can promote sustainable development, thoroughly enjoyed this course

This course is very fine. But certain links are not linked. It is very dificcult to answer quetions.

Incredibly informative and useful course. Thanks to Prof Sachs and Coursera for making it available!

It was an excellent, the one challenge is many of the links on the assignment/exams no longer work.

Ce cours m'a beaucoup appris et m'a montré la réalité des choses ! Il était vraiment bien construit

Gave me a different perspective of looking at things, some which are outside my normal environment.

Un curso completísimo con una visión general y científica muy adecuada a una temática tan compleja

A must have for those working or interested in environmental campaigns, sciences and development.

One of the best courses I have ever encountered in Coursera. It is really a developmental science.

xcellent, engaging, and motivating course that also offers good flexibility for study. Thank you!

Great coure

Too bad that it's starting to be outdated and links are sometimes not working anymore

informative, contemporary (even after those few years), even more relevant during today's crisis

Great Course. The only bad thing is that in the end the course does not provide a certification.

This course gave me enthusiasm and hope that we can change the world through sustainable living

Changed my life. Spurred me on to try an earn a career in the field of Sustainable Development.

My first encounter with this fascinating subject. I learned many things and enjoyed the course.

The course is exellent!

But some of the quizes are outdated due to changes in linked websites.

Great content, however the test and data need to be updated to current events. Would recommend
