If yes, are they doing mitigation risk?
Yes!
Physical casinos are big villains for the environment and online casinos have taken advantage of this problem to raise the "green flag" saying that they are much more sustainable.
This was good, because in contrast, many things have already changed in physical casinos...
Material recycling
Many casinos have started to adopt recycling practices to minimize the environmental impact of their business. This includes things like recycling waste, recycling oil and recycling construction materials.
Renewable Energy
Those bunch of colorful and flashy lights do in fact use a lot of energy, which is why nowadays it is difficult to find a casino that has not yet invested in renewable energy sources such as solar or wind energy to reduce their costs and also have a "lighter carbon footprint", thus improving their image in society.
Food sustainability
Even the way we eat has changed in many casinos, they are taking steps to make their businesses more sustainable when it comes to food too, including organic and locally sourced foods, as well as avoiding buying foods with excessive packaging.
These are some of the changes I have noticed in Argentine casinos (which I have visited recently) and in the reports of other people.
Unfortunately, there are no physical casinos in Brazil, but I would like to know if this has actually happened worldwide, as I hope that physical casinos will never be completely replaced by online casinos.
