Carbon Emissions Education
Learn where they come from and what we can do about them.
What are carbon emissions?
'Carbon emissions' are a shorthand way of referring to carbon dioxide (CO2) released into the atmosphere. CO2 is the primary man-made greenhouse gas; greenhouse gases are associated with climate change. In general, CO2 emissions are released from burning fuels and other processes.
Try out our new tool that calculates your Scope 2 Carbon Score or the amount of CO2 emissions associated with the electricity you purchase from Duke Energy. The tool also displays your Grid Generation Mix based on the fuel sources used to generate the electricity for your home over the last year.
How are emissions categorized?
Scope 1 Emissions:
Emissions that are the direct result of owned or controlled sources (i.e., owned vehicle, gas furnace)
Scope 2 Emissions:
Emissions resulting from the generation of electricity you purchase
Scope 3 Emissions:
Emissions resulting from the supply chain and disposal of all goods and services you consume
Understanding Generation Mix
Renewable and Carbon-Free Sources
With a combined investment of over $2 billion, by 2024, Duke Energy Florida’s solar generation portfolio will include 25 grid-tied solar power plants, which will benefit all Florida customers and will provide about 1,500 MW of emission-free generation. In the Carolinas, we have more than 4,500 MW of solar capacity connected to its grid – including company-owned and independent projects.

Carbon Emissions Sources, aka Fossil Fuels
Coal is fossil fuel in a solid form and is obtained primarily by mining. Coal plants have helped Duke Energy reliably meet customer needs for more than a century, powering growth and economic development in our local communities. Coal fuel represents about 22% of our generation portfolio.
Duke Energy continues to lead the largest planned coal exit in the country, having retired 7,500 megawatts of coal since 2010. We’re targeting energy from coal to represent less than 5% of our total generation by 2030 and a full exit by 2035, subject to regulatory approvals.

What is Duke Energy doing?
We've reduced carbon emissions from electricity generation to 44% below 2005 levels.
We have retired 56 coal units in the last decade.
We own, operate or contract more than 10,500 MW of renewables.
Our near-term goal is to reduce emissions by 50% by 2030.
Our ultimate goal is to reach net-zero by 2050.
