General Terms

Business as Planned (BAP)
The Business-As-Planned (BAP) Scenario evaluated energy and emissions for the city given current and planned and funded policies and actions at all levels by municipal, provincial and federal governments.

Low Carbon Scenario (LC or Low-Carbon)
The Low Carbon Scenario (LCS) evaluated energy and emissions with the reduction potential of 36 additional actions considered. The LCS was informed by the TransformTO community conversations, the Modelling Advisory Group, and meetings with City of Toronto divisions.

Global Warming Potential
Global warming potential (GWP) is a measure of how much energy the emissions of 1 tonne of a gas will absorb over a given period of time, expressed as an comparable amount of 1 tonne of carbon in the form of Carbon dioxide (CO2).

For more information about the Global warming potential and the use of this measure in each scenario modelled, please refer to Section 7: Managing Uncertainty in TransformTO: Climate Action for a Healthy, Equitable and Prosperous Toronto (Report #2, Attachment B)

Heating Degree Days
Heating degree days estimate the heating requirements of buildings. Heating Degree Days (HDD) are calculated as how much colder the mean temperature of a location is than 18°C on a given day. For example, if a location experiences a mean temperature of 8°C on a certain day, there were 10 HDD (Heating Degree Days) that day because 18 - 8 = 10.

Useful Energy
Energy available for use after conversion losses.

Conversion Losses
Energy lost (in the form of heat, light, etc) as energy is transformed from one system to another.

Traffic Zone
The smallest boundary unit of geography used for modelling energy and emissions for the City of Toronto. Also referred to as a "zone" throughout the TransformTO Data Library.


Emissions

Carbon dioxide equivalent
The amount of carbon dioxide emission that would have the same impact, as an emitted amount of a greenhouse gas or a mixture of greenhouse gases. The equivalent carbon dioxide emission is obtained by multiplying the emission of a greenhouse gas by its Global Warming Potential. For a mix of greenhouse gases it is obtained by summing the equivalent carbon dioxide emissions of each gas. The unit of measure is called a mass of the Carbon dioxide equivalent (written as eCO2).
