The Toronto 2030 District is a private-public initiative committed to achieving a low-carbon future. We are a broad stakeholder network comprised of property owners and managers, tenants, utilities, government, service providers and civil society within downtown Toronto. Our focus is on reducing operational greenhouse gas emissions from buildings. The Toronto 2030 District encompasses over 300 million square feet of office, commercial, residential, institutional, and industrial space. The District aims to accelerate the pace of change by recognizing that different buildings have different solutions and that community infrastructure has a large part to play in getting to the solution. To achieve this, the District acts as a learning and knowledge sharing platform aimed at identifying the individual and collaborative opportunities for most effective action. It also seeks context-based solutions that help property owners and managers realize a competitive advantage in cost, resilience, and reputation. The Toronto 2030 District is part of a member network of 22 Districts in cities across North America working to achieve the Architecture 2030 Challenge and meet the Paris Climate Agreement targets.
