do you know any textbook, or any website providing free lectures or lecture notes, or anything, that would introduce me to environmental economics? I have a master in economics so I am not against something with high mathematical formalization. Thank you
I would recommend Natural Resource and Environmental Economics by Perman, Ma, Common, Maddison & McGilvray. The edition linked to is the 4th: my comments are largely based on study of the 3rd edition (of which Maddison was not an author).
The book covers all the main topics of environmental and natural resource economics, including sustainability, pollution, environmental valuation, renewable and non-renewable resources, and accounting for the environment. Climate change is considered within a chapter on international environmental problems. It also addresses relevant background topics including ethics, welfare economics, cost-benefit analysis, and risk and uncertainty. There is a good balance between text, diagrams and mathematics, with some more advanced mathematical topics included in appendices at the end of chapters.
The treatment of pollution is especially detailed, with separate chapters on targets for pollution control, instruments, pollution policy with imperfect information, and stock pollution problems. Natural resource issues are discussed with appropriate use of dynamic optimisation (optimal control). There is critical analysis of the Hotelling Rule (re optimal extraction of a non-renewable resource) and the Hartwick Rule (re saving in a whole economy to sustain a constant rate of consumption).
This is a book which for the most part applies principles and methods of orthodox mainstream economics to the problems of environmental economics. It should be noted that there are alternative approaches to environmental economics such as that of ecological economics, which features in some of the references in Alexandre Michaud's answer.
It is not a book I would recommend to a non-economist, but if you already have a masters in economics its level should be very suitable.
I have plenty. First of all, you absolutely need to look up this website:
On exploring-economics, you can find detailed articles and sources about the main fields in economics, including environmental economics. They also provide lectures.
Here's my reading and lecture list in environmental economics for you (keep in mind that environmental and ecological economics are different perspectives. The first more associated with neoclassical economics, and the other composed of an array of critiques):

Additionnal lectures and reading
However, only exploring economic lectures and readings is not enough. Everything here is based on philosophical supposition, who also need to be explored and criticized. Here's a few books and lectures on the subject:
Arne Naess' Deep Ecology
Arne Naess. 1974. Ecology, community, and lifestyle. David Rothenberg
Ecology as responsibility - the deontological framework
Hans Jonas, The Responsibility principle.
Murray Bookchin, The Ecology of Freedom
