To meet our climate goals, we need to build better.
Accounting for 37 percent of global emissions, our buildings and construction sectors urgently need to decarbonize. Carbon-intensive building materials, outdated construction methods and inefficient heating and cooling are just some of the factors that make buildings the single-largest source of greenhouse gas emissions in dense urban areas. In Toronto, existing homes and buildings account for over 50 percent of emissions. With millions of new homes needed by 2030 to support Canada’s growing population, this new construction could add 18 megatonnes of emissions annually until 2030. Through this mission, MaRS is helping accelerate the adoption of Canadian innovations that can be part of the solution to decarbonizing our existing buildings and building better new ones.
To meet our climate goals, we need to build better.
Better Buildings mission objectives
The Better Buildings mission aims to help Canada achieve its climate goals in three key ways:
- Adopting innovations that can reduce the operational emissions of Canada’s buildings.
- Accelerate the uptake of low-carbon building materials and methods.
- Amplify the role of Canadian cleantech in existing efforts to create a more resilient, adaptive and affordable built environment.

Better Buildings: Hospitality and Recreation Business Cohort
MaRS is launching the Better Buildings: Hospitality and Recreation Business Cohort, an 18-month program that helps owners and franchisees of hotels, motels, inns, gyms, clubs and spas reduce operating expenses, maximize efficiency and enhance customer experience. Each business in the cohort will complete three phases of work: assessment, planning and implementation. In the last phase, each company will complete an initial deployment project of a decarbonization technology with a climate venture.

The Future of Data Centres in Ontario
Data centres are fundamental to our economy, enabling increased productivity and competitiveness in such critical sectors as manufacturing, healthcare and logistics.
But how can Ontario meet the overwhelming demand for electricity-intensive data centres without overwhelming our energy system? In this special report, MaRS and Mantle Climate explore the potential growth trajectories of data centre infrastructure in Ontario and provide cross-sector insights to support the province’s emerging digital infrastructure strategy.

The Road-Mapping Initiative to Networked Geothermal (RING)
A project under Better Buildings that convened multi-industry stakeholders to explore an affordable path to decarbonizing heat delivery in buildings on a community-wide scale in Ontario, through deployment of networked geothermal, a form of thermal energy network (TEN).
