Green entrepreneurship is form of entrepreneurship that deals with designing and implementing solutions for environmental problems with the aim of achieving business based on sustainability. In order to achieve this, the development of eco-innovations is crucial because they promote sustainability throughout the product's life cycle and that's why there are considered as a key driver for the transition to the concept of a circular economy, which goal is to eliminate waste. By using green certificates, companies in a credible way show their commitment to sustainability, while some companies that do not apply green practices in their business use a marketing trick known as greenwashing, with which they try to make consumers believe that their products are environmentally friendly, when in reality they are not. In order for as many companies as possible to turn to green entrepreneurship, it is necessary to create a stimulating environment that would facilitate and attract current and future entrepreneurs to follow these steps.
