We conducted our first greenhouse gas (GHG) emissions inventory to generate a comprehensive understanding of our energy use and emissions output across our operations. The results of this inventory will be used to identify opportunities for improvement and as a baseline against which we will track our progress over time.
National Vision’s GHG Emissions
Scope 1: Emissions from sources that are owned or controlled by National Vision. This includes natural gas and propane used at our buildings and fuel used in company vehicles.
Scope 2: Indirect emissions from the generation of electricity purchased by National Vision.
The inventory focused on National Vision’s Scope 1 and 2 emissions for calendar year 2020. We used the Operational Control approach and the GHG Protocol Corporate Standard as guidance, and we sourced all global warming potential values from the IPCC’s Fifth Assessment Report. When data was unavailable, we followed best practice guidelines to estimate impact.
In 2020, our Scope 1 emissions totaled about 4,000 metric tons of carbon dioxide equivalent (CO2e), and our Scope 2 emissions totaled about 35,200 metric tons of CO2e, resulting in a combined Scope 1 and Scope 2 emissions of 39,200 metric tons of CO2e. Our total electricity consumption was about 78,700 MWh. Natural gas and propane usage at our facilities comprised the largest portion of our Scope 1 emissions, purchased electricity was the largest contributor of our Scope 2 emissions, and the majority of our combined Scope 1 and 2 emissions came from National Vision facilities, specifically our retail locations.
Since the inventory covers 2020 emissions, the results reflect impacts of the COVID-19 pandemic on our operations. In 2020, to best protect our customers, patients, associates, and network of optometrists, we closed our stores to the public for a period of time in the spring. We also reduced production at our labs because of a temporary decrease in demand. As the U.S. continues to recover from the pandemic, we have driven a strong return in our business activities and will likely see an increase in Scope 1 and 2 emissions as a result.
