Emissions per Capita of the Top 30 U.S. Investor-Owned Utilities
Approximately 25% of all U.S. greenhouse gas emissions (GHG) come from electricity generation.
Subsequently, this means investor-owned utilities (IOUs) will have a crucial role to play around carbon reduction initiatives. This is particularly true for the top 30 IOUs, where almost 75% of utility customers get their electricity from.
This infographic from the National Public Utilities Council ranks the largest IOUs by emissions per capita. By accounting for the varying customer bases they serve, we get a more accurate look at their green energy practices. Here’s how they line up.
Per Capita Rankings
The emissions per capita rankings for the top 30 investor-owned utilities have large disparities from one another.
Totals range from a high of 25.8 tons of CO2 per customer annually to a low of 0.5 tons.
|Utility||Emissions Per Capita (CO2 tons per year)||Total Emissions (M)|
|Berkshire Hathaway Energy||14.0||57.2|
|American Electric Power||9.2||50.9|
|Florida Power and Light||8.0||41.0|
|Portland General Electric||7.6||6.9|
|Pacific Gas and Electric||0.5||2.6|
|Next Era Energy Resources||0||1.1|
PNM Resources data is from 2019, all other data is as of 2020
Let’s start by looking at the higher scoring IOUs.
TransAlta emits 25.8 tons of CO2 emissions per customer, the largest of any utility on a per capita basis. Altogether, the company’s 630,000 customers emit 16.3 million metric tons. On a recent earnings call, its management discussed clear intent to phase out coal and grow their renewables mix by doubling their renewables fleet. And so far it appears they’ve been making good on their promise, having shut down the Canadian Highvale coal mine recently.
Vistra had the highest total emissions at 97 million tons of CO2 per year and is almost exclusively a coal and gas generator. However, the company announced plans for 60% reductions in CO2 emissions by 2030 and is striving to be carbon neutral by 2050. As the highest total emitter, this transition would make a noticeable impact on total utility emissions if successful.
Currently, based on their 4.3 million customers, Vistra sees per capita emissions of 22.4 tons a year. The utility is a key electricity provider for Texas, ad here’s how their electricity mix compares to that of the state as a whole:
|Energy Source||Vistra||State of Texas|
Despite their ambitious green energy pledges, for now only 1% of Vistra’s electricity comes from renewables compared to 24% for Texas, where wind energy is prospering.
Based on those scores, the average customer from some of the highest emitting utility groups emit about the same as a customer from each of the bottom seven, who clearly have greener energy practices. Let’s take a closer look at emissions for some of the bottom scoring entities.
Utilities With The Greenest Energy Practices
Groups with the lowest carbon emission scores are in many ways leaders on the path towards a greener future.
Exelon emits only 3.8 tons of CO2 emissions per capita annually and is one of the top clean power generators across the Americas. In the last decade they’ve reduced their GHG emissions by 18 million metric tons, and have recently teamed up with the state of Illinois through the Clean Energy Jobs Act. Through this, Exelon will receive $700 million in subsidies as it phases out coal and gas plants to meet 2030 and 2045 targets.
Consolidated Edison serves nearly 4 million customers with a large chunk coming from New York state. Altogether, they emit 1.6 tons of CO2 emissions per capita from their electricity generation.
The utility group is making notable strides towards a sustainable future by expanding its renewable projects and testing higher capacity limits. In addition, they are often praised for their financial management and carry the title of dividend aristocrat, having increased their dividend for 47 years and counting. In fact, this is the longest out of any utility company in the S&P 500.
A Sustainable Tomorrow
Altogether, utilities will have a pivotal role to play in decarbonization efforts. This is particularly true for the top 30 U.S. IOUs, who serve millions of Americans.
Ultimately, this means a unique moment for utilities is emerging. As the transition toward cleaner energy continues and various groups push to achieve their goals, all eyes will be on utilities to deliver.

ESG Data: The Four Motivations Driving Usage
ESG controversies can damage a company’s value, but ESG data may be able to help manage this risk. What are other reasons for using ESG data?
ESG Data: The Four Motivations Driving Usage
Data is key to the environmental, social, and governance (ESG) revolution. Access to granular ESG data can help boost transparency for market participants. Unfortunately, 63% of U.S. and European asset managers say a lack of quantitative data inhibits their ESG implementation.
Being clear on the potential application of this data is equally important.
- Investors and banks can use ESG data for risk assessment, to spot opportunities, and to push companies for change.
- Companies can publish their own ESG data, quantify progress on their ESG goals, and use data to inform decisions.
- Policymakers can use ESG data to inform regulatory frameworks and measure policy effectiveness.
This graphic from ICE, the second in a three part series on the ESG toolkit, explores four primary motivations of ESG data users.
1. Right Thing
The objective: Having a positive social or environmental impact.
For investors, this can involve screening out companies that conflict with their values and selecting companies that align with their ESG objectives.
As another example, it can involve comparing the social impact of municipal bonds. One way investors can measure social impact is through scores that quantify the potential socioeconomic need of an area, using metrics like poverty and education levels. Here are the social impact scores for three actual municipal bonds issued in Florida.
|State||Bond Issuer||Social Impact Score
(Higher = larger potential impact)
Issuer #1’s bond is projected to have a community impact that is nearly twice as high/positive as Issuer #3’s bond.
For companies, doing the right thing can include assessing their progress on ESG goals and benchmarking themselves to peers. For example, gender and racial representation is a growing area of focus.
The objective: Managing ESG risks, such as climate and reputational risks.
For investors, this can involve back-testing or analysis around specific risk events before they materialize. Here are the risk profiles of two actual municipal bonds in California. The shown bonds are practically identical in many ways, except their wildlife score.
|Issuer #1||Issuer #2|
|Current Coupon Rate||5.0%||5.0%|
|Maturity Date||Aug 01, 2048||August 01, 2048|
|Price to Date (Call Date)||Aug 01, 2027||Aug 01, 2027|
|Wildfire Score (Higher = more risk)||3.6||2.7|
Managing ESG risk can also involve analyzing a company’s policies and governance for weaknesses. This is important as an ESG controversy can have long-lasting effects on the valuation of a company.
In one study, companies with ESG controversies dropped more than 10% in value relative to the S&P 500. They hadn’t fully recovered a year after the incident.
The objective: Targeting outperformance through ESG analysis.
Selecting companies with strong ESG data can align with long-term growth trends and may help boost performance. For heavy emitting industries, research indicates that European companies with lower emissions trade at much higher valuations. The chart below shows companies’ price-to-book ratio relative to the Stoxx 600* sector median.
|Above Median Emission Intensity (Bad)||1.9||1.1||2.0|
|Below Median Emissions Intensity (Good)||2.7||1.9||2.1|
*The Stoxx 600 Index represents large, mid and small capitalization companies across 17 countries of the European region: Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
Energy companies with low emissions trade at a valuation nearly two times higher than energy companies with high emissions.
The objective: Understanding and complying with relevant ESG regulation.
The International Sustainability Standards Board has announced a global reporting proposal aligned with the Task Force on Climate-related Financial Disclosures (TCFD). In addition, a growing number of jurisdictions will require organizational reporting that aligns with the TCFD.
- European Union
- Hong Kong
- New Zealand
Not only that, a European Union regulation known as Sustainable Finance Disclosure Regulation (SFDR) came into effect in 2021. It seeks greater transparency in disclosures from firms marketing investment products. Even firms located outside the EU could be impacted if they serve EU customers. In total, the market cap of these non-EU companies exposed to SFDR amounts to $3.2 trillion.
Matching ESG Data with Motivation
There will be growing demand for transparent data as ESG investing flourishes. To remain competitive, investors, policymakers, and companies need access to ESG data that meets their unique objectives.
In Part 3 of the ESG Toolkit series sponsored by ICE, we’ll look at key sustainability index types.
The Hierarchy of Zero Waste
In a world that generates 2 billion tonnes of waste every year, waste management has become a global concern. Here are some strategies to help guide zero waste policies.
The Hierarchy of Zero Waste
Many cities have set ambitious zero waste targets in the upcoming decades.
The idea is to have communities where waste generation is avoided, and products are shared, reused, or refurbished.
This graphic, sponsored by Northstar Clean Technologies, shows the main strategies and hierarchy to guide zero waste policies.
What is Zero Waste?
In a world that generates approximately 2 billion tons of waste every year, waste management has become a global concern. Thus, countries and cities are increasing efforts to reduce or even eliminate waste when possible.
The Zero Waste International Alliance defines zero waste as “the conservation of all resources by means of responsible production, consumption, reuse, and recovery of products, packaging, and materials without burning and with no discharges to land, water, or air that threaten the environment or human health.”
Becoming a zero waste community, however, is a complex task.
Currently, Sweden recycles 99% of locally-produced waste and is considered the best country in the world when it comes to recycling and reusing waste. However, such results only came after almost 40 years of recycling and reuse policies.
In line with this, here are seven commonly accepted steps you can use to achieve zero waste:
1. Rethink, Redesign Products
The global population consumes 110 billion tons of materials each year, but only 8.6% is reused or recycled. In a zero waste society, single-use products are avoided and products are designed with sustainable practices and materials.
Consumption must be planned carefully to reduce the unnecessary use of materials. Consumers must choose products that maximize the usable lifespan and opportunities for continuous reuse. Companies must minimize the quantity and toxicity of materials used.
The value of products is maintained by reusing, repairing, or refurbishing for alternative uses.
Products are diverted from waste streams and recirculated into use. Resilient local markets are developed, allowing the highest and best use of materials.
5. Material Recovery
Component materials like cement, metals, or asphalt are recovered from mixed waste and collected for other applications.
In the U.S. alone, around 12 million tons of asphalt shingle tear-off waste and installation scrap are generated from roof installation each year. Currently, more than 90% of this is discarded in landfills. This material can be repurposed to create new products like liquid asphalt, fiber, and aggregate.
6. Residuals Management
Waste is biologically stabilized and sent to responsibly managed landfills.
The production of materials that are not recoverable and can negatively impact the environment must be avoided.
Reducing our Climate Impact
Reducing, recycling, and recovering materials can be a key part of a climate change strategy to reduce our greenhouse gas emissions.
According to the U.S. Environmental Protection Agency, about 42% of all greenhouse gas emissions are caused by the production and use of goods, including food, products, and packaging.
Even though 100% zero waste may sound difficult to achieve in the near future, a zero waste approach is essential to reduce our impact on the environment.
Northstar Clean Technologies aims to become the leading recovery and reprocessing company for asphalt shingles in North America.
