We continue to work hard to identify innovative ways to reduce our emissions and drive greater energy efficiency across Verizon’s operations. Even as we grow our networks and bring 5G to our customers, we are working to reduce our footprint by:
- Moving from older technologies to newer, more energy-efficient ones. This includes migrating copper-based services to fiber technologies, as well as migrating to our newer intelligent edge network platform.
- Installing energy-efficient systems and employing energy management best practices at our facilities ranging from LED lighting to high-efficiency uninterruptible power supplies.
- Using better cooling technologies in our data centers, such as bringing outside air into the HVAC system when the temperature outside is cooler than it is inside.
- Investing in green energy, both on site at our facilities and through Virtual Power Purchase Agreements in support of a greener nationwide grid.
Improving network energy efficiency
Ninety-one percent of Verizon’s emissions come from the electricity we use to power our networks, so maximizing energy efficiency is a critical priority for us. We are driving energy efficiency in our networks through a variety of interventions, including:
- Auditing the temperature at our technical network facilities so that cooling systems can be decreased where overcooling may have been occurring. We have been able to increase our technical network air temperatures with no detrimental effect on network performance or reliability.
- Replacing and upgrading older cooling systems with newer, high-efficiency cooling systems that meet or exceed the latest industry energy efficiency standards. These upgrades include systems equipped with “free cooling” economizer systems that have the ability to significantly reduce cooling energy during the appropriate climate conditions.
- Deploying smart cooling systems across a number of technical network facilities to optimize the cooling system capacity and telecommunications equipment demand through machine learning algorithms.
These interventions reduce overall site energy usage and maintenance costs, as well as extend the life expectancy of our equipment.
We will continue to report our progress as we make advances, with our results independently assured every year. In 2019, we commissioned independent external assurance of our Scope 1, 2 and 3 (exclusively business travel) greenhouse gas (GHG) emissions and carbon intensity for 2018 and reported the results in our 2019 CDP Climate Change Response and on our corporate website. In 2018, we achieved a 46% reduction in the carbon intensity of our operations against a 2016 baseline. We are currently undergoing independent external assurance of our 2019 GHG emissions.
