Take urgent action to combat climate change and its impacts.
Entergy is taking aggressive action to combat climate change and its impacts. Since 2001, we have operated under voluntary commitments to stabilize and reduce our CO2 emissions as part of our actions to be environmentally responsible and manage risks related to potential federal legislation of emissions.
Now we are enhancing our climate leadership to span five decades with a commitment to net-zero CO2 by 2050.
Learn how we expect to achieve this commitment while remaining relentlessly focused on reliability and affordability with an overview here. Details of our planned pathway to net-zero are available in this addendum to our 2019 Climate Report and Scenario Analysis.
Entergy’s net-zero carbon emissions commitment builds on the company’s 2030 goal announced in 2019. Our plan to reduce our emission intensity by half the level it was in 2000 is outlined in our climate report.
On an emissions-per-megawatt-produced basis, Entergy is one of the cleanest utilities in the U.S. According to the 2020 Benchmarking Air Emissions Report, Entergy is the seventh-largest of the top 100 power producers. At the same time, Entergy ranks sixth in the production of zero-emitting energy. Entergy's CO2 emission rate is the fifth lowest among the top 20 privately owned and investor-owned power producers. For more details on how Entergy compares, see the charts below:
Our current commitment is to maintain CO2 emissions from Entergy-owned power plants and controllable power purchases through 2020 at 20 percent below year 2000 levels. Through 2019, our cumulative CO2 emissions were approximately 8% below our target.
Average Heat Rate by Fuel
2019 Coal and Gas
As a continuation of Entergy’s two decades of analysis, engagement and disclosure on climate change risks and opportunities, we published “Climate Scenario Analysis and Evaluation of Risks and Opportunities” in 2019. Our climate report explains how customer and sector partnerships focused on beneficial electrification efforts can result in economy-wide carbon emission reductions, especially as Entergy’s already low carbon emission intensity continues to decrease through portfolio transformation.
In the climate report, we set a new emissions strategy for the next decade by committing to reduce our emission intensity by 50% from our 2000 level by 2030. Emission intensity is measured by pounds of CO2 produced per megawatt hour. This means that for every unit of electricity Entergy generates, we will emit half the CO2 that we emitted in 2000.

Meeting Our Climate Goal
Planned investments in portfolio transformation, grid modernization and nuclear improvements are increasing our overall efficiency and reducing our environmental impact. Nuclear generation remains a key component of our clean generation resources. Combined-cycle gas turbine plants are highly efficient and reduce the amount of fuel burned per kilowatt hour of energy produced, thus greatly reducing emissions when compared to coal or older gas units. Our strategy has allowed the deactivation of about 7 GW of older, less efficient gas or oil units since 2000. Our new-build natural gas-powered units, in operation or under construction, represent roughly 7.5 GW of highly efficient generation. These units emit approximately 40% less CO2 per MWh than older legacy gas units. Looking ahead, we currently expect to deactivate approximately 7 GW of legacy gas and coal units while adding 7 to 8 GW of new generation from 2022 through 2030 as we continue our transformation strategy.
In 2019, renewable resources (solar, wind renewable energy credits, hydro, biomass, landfill gas, and waste heat) supplied approximately 2.8 million MWh, or approximately 2 percent of total electric demand, to our utility customers. While still a small portion of our utility generation, as technology and economics continue to improve, we are pursuing additional utility-scale renewable opportunities as well as potential applications for distributed energy resources. We currently have nearly 2 GW of renewable projects in various stages of development or planning.

In 2018, Entergy announced that Entergy Arkansas and its affiliates will begin to use only low-sulfur coal at White Bluff and Independence coal generating plants starting no later than June 30, 2021; will cease to use coal at White Bluff no later than the end of 2028; and will cease to use coal at Independence no later than the end of 2030. These actions will result in Entergy closing 80 percent of its coal fleet. In addition, we will continue to use only natural gas at Lake Catherine Unit 4 until ceasing plant operation by the end of 2027. In 2030, approximately 1.2% of our generation will be from coal as outlined on page 34 of our climate report.
Further details of our investments in cleaner resources are available in our 2019 Integrated Report here.
These investments have greatly reduced both absolute air emissions and emission rates since 2000. In 2018, the most recent benchmarking data available, Entergy’s emission rate was 617 pounds per MWh, much lower than the national average of 1,009 pounds per MWh.
We are also investing in owned and contracted carbon-free renewable generation. In 2019, renewable resources (solar, wind renewable energy credits, hydro, biomass, landfill gas, and waste heat) supplied approximately 2.8 million MWh, or approximately 2 percent of total electric demand, to our utility customers.
