Carbon Offsets

Entergy's Double Your Difference Carbon Offset Matching Program

Through Entergy’s Double Your Difference Offset Matching program, individuals can purchase carbon offsets to reduce their carbon footprint beyond what is typically possible with efficiency. When you purchase an offset, Entergy will double the impact of your purchase by matching up to five tons of carbon offsets purchased per individual.

What is an offset?

A greenhouse gas (GHG) offset – often also referred to as a carbon offset – reduces the amount of carbon you might normally emit by funding projects that reduce or avoid greenhouse gas emissions. Offsets get their name because they compensate for greenhouse gases that are emitted into the atmosphere somewhere else.

Why are offsets important?

Offsets are an important climate solution because they can be implemented quickly and at a relatively low cost.  Given the massive amount of emissions reductions that must be achieved to stabilize the earth’s climate, the growing sense of urgency for immediate action, and the societal cost savings that offsets represent, offsets are an indispensable component to real climate change solutions.

What Makes a Good Offset?

To be certain that an offset project results in a true net benefit to the environment, it must meet several essential tests:

  1. It must be demonstrated that an offset project would not have otherwise occurred without the existence of the offset market—in other words, it wouldn’t have happened anyway.  In the policy world, this concept is known as “additionality” because an offset project must be “in addition to” business-as-usual.
  2. Results must be rigorously verified and quantified and be permanent

To measure the impact of the offset, a projection of emissions without the offset project must be developed (a “baseline”), and then actual emissions must be measured. The difference between the actual emissions and what would have otherwise been emitted is the GHG benefit that can be sold as an offset. A third party with no financial interest in the project must verify the project and calculations used to quantify the results.

Additional Co-Benefits to Offsets

In addition to reducing GHG emissions, offsets commonly produce other environmental, social, and economic co-benefits including (depending on the type of project):

  • Reductions in other atmospheric pollutants
  • Restoring forests
  • Improving watersheds and water quality
  • Protecting endangered species
  • Creating jobs
  • Saving money on electricity and gasoline

Why Purchase Offsets?

While an individual’s primary goal should be to reduce his or her personal carbon footprint as much as possible, it is impossible to reduce it completely.  Through the purchase of offsets, an individual can pay to help reduce carbon emissions somewhere else and further reduce his or her footprint in the process.
