City of Salaberry-de-Valleyfield


With its 40,000 residents, the city of Salaberry-de-Valleyfield is the Suroit regional capital and one of the largest municipalities in Quebec. Largely build around heavy industries, Valleyfield has shown excellent leadership over the last few years to earn its place among sustainable development leaders. Having developed one of the strongest sustainable development environment action plans in Quebec -  (PADD-E), Valleyfield wanted to establish its carbon balance and find ways to reduce it. The city found it important to do this exhaustively, to integrate it with the PADD-E system, and develop it with a collaborative approach allowing municipal employees to develop a sense of ownership with the plan. Finally, it was essential for the city to become autonomous in this respect and manage its own carbon balance in the years to come.


To meet its objectives in assessing the GHG emission inventory, Takt-etik implemented the Nos impacts tool, an innovation allowing the city to self-manage its carbon footprint. The first city in Canada to use this system, Valleyfield was able to calculate its balance faster than with the tools normally used by other municipalities. Thanks to Nos impacts, we were able to identify, together with city staff, GHG emission reduction opportunities.

Following this work and with the help of the different municipal services, we developed a reduction plan that links with the PADD-E system and inspires best practices for municipal management.


Thanks to the Nos impacts tool and the approach adopted by Takt-etik, the city of Valleyfield is now able to manage its own carbon balance. In coming years, the city will be able to obtain yearly balances while other Quebec municipalities only obtain similar data every three years.

Moreover, due to the simplicity of the method, the city can derive more precise carbon balances than other cities by computing, for example, the commuting distances of its employees and immediately obtaining a comparative chart between 2009 and 2010.

To this day, the reduction plan is still pursuing its goals, but we are confident that it will lead to measurable, realistic and constant GHG emission reductions over the coming years.
