Our sustainability data

EDF calculates an annual greenhouse gas emissions inventory that includes emissions from staff and trustee travel, office energy and paper.

We calculate those emissions using the standard metric in climate research and policy — global warming potential, or GWP, which measures climate impacts in both the near and long term. We use GWP with two time scales as opposed to the common approach of using just one.

Using two allows us to understand the effects of our emissions both in the near term (more than 20 years) and the long term (more than 100 years).

By calculating the carbon dioxide equivalence, or CO2e, of EDF’s greenhouse gas emissions using two different GWP values — GWP 20 and GWP 100 — we have estimated the climate impact that EDF’s emissions will have during our lifetime and during the lifetimes of future generations.

Our total emissions

EDF calculates total emissions on an annual basis. Our total annual emissions for 2020 were 5,500 (GWP 100) / 6,700 (GWP 20) tons of carbon dioxide equivalent (tCO2e). For context, this is the equivalent of EDF adding about 1,300 cars to the road in 2020.

EDF strives to use the best available methodologies to calculate our emissions inventory, including those set out by the Greenhouse Gas Protocol, the U.S. Environmental Protection Agency, and the United Kingdom Department of Environment, Food and Rural Affairs. As best practices in greenhouse gas accounting continually evolve, we are committed to reviewing our methodology annually and reporting any updates.

How we categorize emissions

We categorize emissions into “scopes” as defined by the Greenhouse Gas Protocol.

  • Scope 1: Direct greenhouse emissions occurring from sources controlled or owned by an organization. For EDF, natural gas is a scope 1 emission.
  • Scope 2: Indirect electricity greenhouse emissions from using purchased electricity, steam, heat or cooling. For EDF, purchased electricity and steam are scope 2 emissions.
  • Scope 3: Other indirect greenhouse gas emissions that are consequences of operating a business. For EDF, business travel and paper usage and mailings are scope 3 emissions.

How we offset our footprint

EDF calculates an annual greenhouse gas emissions inventory that includes emissions from staff and trustee travel, office energy and paper.

In an effort to mitigate our environmental impact, EDF supports greenhouse gas reduction projects around the world. To offset our 2019 footprint, we supported the New Bedford Gas-to-Energy Landfill project in Massachusetts and the Paradigm Clean Cookstoves Project in Kenya.

Soon, we will announce the projects we will support to offset our 2020 footprint.
