As part of this vision, we’re also focused on becoming a net-zero company by 2040 and enabling a net-zero economy by 2050. We have already made major strides to a sustainable future. In 2014, OPG burned its last piece of coal to make electricity, which represented one of the world’s single-largest climate change-specific actions. Today, through the dedication of more than 9,500 employees, OPG generates almost half of the electricity that Ontario’s homes, schools, hospitals, and businesses rely on each day. We are committed to ensuring our energy production is reliable, safe, and environmentally sustainable for Ontarians today and for the future.
