Simon Marcotte, President, and Chief Executive Officer of Black Swan, commented: "As the world continues its transition towards reducing CO2 emissions, substantial investments have been directed towards the transportation industry, facilitating the development of battery manufacturing, as well as a transformation of energy generation and transmission. Government-established standards have been the driving force behind this phenomenon. It is only a matter of time before similar standards are set for the concrete industry, which alone accounts for 8% of CO2 emissions.¹ The recent announcement by the City of Toronto (refer to the press release dated May 24, 2023) is a clear indication of this potential."
