If today, environmental, social, and governance aspects, so widely disseminated in the ESG acronym, are considered essential in conducting any activity, for TIM, the sustainable development agenda is part of an evolutionary and intentional journey. Continuously, we challenge ourselves with goals and commitments that contribute to building a fairer, more inclusive, and diverse society, and reduce environmental impacts, in pursuit of a circular and low- carbon economy.
