All data is from sampling from two main data sources and some complementary sources:
- annual emissions records submitted by Canada to the United Nations
- company and institutional emissions records filed with Environment Canada,
- other specific data, such as forecasted projets of tar sands mining.
The first database presents the whole spectrum of emissions. The second provides a greater level of detail, especially for three of the examined sectors: industry, electricity generation and hydrocarbon production. For the first version of the tool, three years have been selected in the periods 2004-2012, 2006, 2009 and 2012.
- sector/subsector/component if available (e.g. business/facility/type of vehicle)
- CO2-equivalent emissions level/type of gas emitted,
Projections were made at detailed levels for 2020 and 2030. They were based on observation of trends with linear equations associated with threshold effects, and are adjustable.
Policy interventions are then simulated as interventions on projected data. The review tool contains a series of measures inspired by existing plans, studies and examples of regulations set elsewhere and configured for Canada. They are parameterized according to of several factors and assumptions.
- integration of new emissions data,
- integration of changes in emission counting modes (such as the value of the global warming potential of methane)
- updating of the projection methods, depending on the progress of projects (cancelling of project, launch of new emitting projects...),
- and... the establishment of new GHG reduction measures.
