Definition : Greenhouse gas (GHG)

Gas composed of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) that is released into the atmosphere. Greenhouse gases are attributable to the building's energy consumption, including direct emissions from on-site fuel combustion and indirect emissions from the consumption of electricity, steam, hot water or cooled water from a distribution system.

January 27, 2023 - The Mayor of Montréal, Valérie Plante, made a commitment on September 23, 2019, before the heads of state and government meeting in New York, to reduce the Montréal community's greenhouse gas (GHG) emissions by 55% by 2030 compared to their 1990 level. To become carbon neutral by 2050, the City of Montréal adopted the By-law concerning greenhouse gas emission disclosures and ratings of large buildings (21-042).  The objective is to know the use of fossil fuels in buildings in order to reduce consumption. This regulation, which came into force on October 4, 2021, requires owners of large buildings to disclose the sources and amounts of energy their buildings use. By June 30 of each year, a declaration of such disclosure must be filed.

Electric vehicles (EV) are increasingly seen as one of the ways to reduce the impact of car traffic on the climate. With the effort to be made to substantially reduce Quebec's greenhouse gas emissions and to contain the increase in temperatures by the end of the century, the sale of EV has become a must. In Quebec, in 2030, the number of EV is expected to increase to 1.5 million, or 30% of the Quebec car fleet. In 2035, the sale of new gasoline cars will be banned in Quebec and Canada. Paradoxically, the majority of buildings held in divided co-ownership are not equipped to allow EV charging. In addition, the declarations of co-ownership of these buildings have not provided for anything on this issue.
