Giving Our Skies a Breath of Fresh Air
Tackling climate change is a critical undertaking. That’s why SUEZ North America is rising to this huge challenge not only by optimizing energy consumption, but by reducing greenhouse gas (GHG) emissions and promoting renewable energy as well.
From 2013 to 2014, we reduced GHG emissions 5% equal to taking 3,814 cars off of the road

Improving Energy Efficiency
Between 2010 and 2013, we’ve achieved an 18% improvement in energy efficiency for all water operations based on the ratio of energy consumption to revenue.
As we successfully reached our goal, we set up a new, ambitious goal of 5% reduction in energy consumption per volume of water produced and distributed by 2016 for the water operations owned by SUEZ. Since 95% of our GHG emissions come from energy use, our goal by 2016 is also to reduce them by 5% compared to 2013 levels.

Optimizing Electricity Consumption in Operations
In 2014, we conducted 123 pump efficiency tests and 18 blower and fan efficiency tests, reducing the company’s carbon dioxide emissions by 18,000 tons. We focused on pump efficiency because pumping accounts for about 80% of the company’s energy use. Operations with the highest electricity consumption—such as New Jersey, Indianapolis and Long Island— are monitored very closely to ensure sustainable reduction of carbon dioxide emissions.
Building a More Efficient Service Fleet
Part of our job in supplying millions of people with reliable water involves maintaining a vast infrastructure of aging underground pipes. In the New York metropolitan area alone, we employ a fleet of 430 vehicles each and every day to monitor and repair this piping infrastructure.
In 2012 we saw an opportunity to reduce the fleet’s carbon footprint by implementing an idle reduction program. We trained drivers to turn off their vehicles’ engines when they were not being used and also installed GSP tracking to track idle time on a monthly basis.
The program was a resounding success and was recognized by Transportation & Infrastructure Magazine. From 2010 to 2014, we were able to reduce idle time by 25% and save 7,500 gallons of fuel.
Reducing Greenhouse Gas Emissions
Our greenhouse gas emissions, resulting from energy and fuel consumption, decreased by 5% between 2013 and 2014. This reduction is mainly due to changes in the way energy is produced in the United States, with progress made towards less CO2 emitting technologies.
