Sustainability at all 3 levels
Environmental reports show that the vast majority of the global warming that has occurred in recent decades can be attributed to the greenhouse gas emissions – especially carbon dioxide (CO2) – caused by humans. Climate change is one of the key challenges of the 21st century. Unfortunately, its effects are becoming ever more threatening. Barely a day goes by when we do not hear about natural disasters caused by extreme weather conditions or about the melting glaciers and rising sea levels.
