PATHWAYS TO NET ZERO
Looking Beyond the Energy System
Some Canadian greenhouse gas (GHG) emissions are not directly related to energy use, but stem from industrial processes and products, agriculture and waste. These emissions, which are entangled with a variety of existing systems of provisioning, may be particularly challenging to address.
Although the journey to net zero is primarily about building systems that avoid GHG emissions, it will also involve some application of negative emission approaches that remove carbon dioxide from the atmosphere. This can offset residual emissions which prove technically challenging or too expensive to eliminate. Negative emissions approaches (for example, planting forests, CCS on biomass, or direct air capture) may ultimately be required to draw down atmospheric GHG concentrations.
