The Toronto Green Standard (TGS) is a two-tier set of environmental performance measures that facilitates sustainable new
development that address the City of Toronto’s environmental pressures including: improved air quality, energy use and climate change, water quality, quantity and efficiency, ecological protection and enhancement and solid waste diversion and reduction.The TGS was introduced as a voluntary standard for new development in 2006. TGS became mandatory in 2010 (TGS Version 1.0) and was updated in 2013 (TGS Version 2.0).
TheTGS includes Tier 1 performance measures, required through the planning process and a voluntary Tier 2 standard of higher performance measures which may be eligible for a development charge refund incentive.
The Toronto Green Standard has proven to be an effective tool to ensure new development is more sustainable, resilient and on target to achieve the City’s greenhouse gas (GHG) emission reduction targets. As of 2017, over 1,300 developments have been required to meet Tier 1 and 20 projects have been certified to Tier 2.
