Rules of the Game

Here are the key principles that guide Regional Sustainability Initiative targets.

Rule # 1 All your organizational space in the Region of Waterloo is included in your environmental inventories.
Rule # 2 You have 4 years to make your E-Score  public or set a greenhouse gas, waste, or water reduction target.


Rule # 3 You must report your emissions annually. We  allow the purchase of carbon offsets1 and REC’s2 as long as they account for no more than 49% of your reduction, with not more than 10% being from outside Canada. Targets may be absolute3 or intensity4 based. You can learn more about offsets here
Rule # 4 For each 10 year target, the baseline can be set up to 3 years before joining the Regional Sustainability Initiative.


Rule # 5 For greenhouse gas emissions, organizations must report use Scopes 15 and 26. Scope 37 emissions are optional.
  1. Carbon offsets – present the act of reducing, avoiding, destroying or sequestering the equivalent of a ton of greenhouse gas in one place to “offset” an emission taking place somewhere else.
  2. Renewable Energy Credits – represent one megawatt hour (MWh) of energy generated from a clean, renewable source, such as wind, solar, hydro, or certain types of renewable biomass.
  3. Absolute – Absolute greenhouse gas emission reduction is defined as a total reduction emission over a time period (ie. 40% reduction below 2010 levels by 2010)
  4. Intensity – Intensity greenhouse gas emission reduction is defined as a reduction of emissions based on a specific activity (ie,. Square foot of building, number full-time equivalent employees)
  5. Scope 1 Emissions – all greenhouse gas emissions resulting from direct sources owned or controlled by the member ie: natural gas and fleet
  6. Scope 2 Emissions – all greenhouse gas emissions resulting indirect sources of purchased electricity.
  7. Scope 3 Emissions – indirect greenhouse gas emissions, such as the extraction and production of purchased materials and fuels, transport-related activities in vehicles not owned or controlled by the organization and other outsourced activities.
