Uranium: Powering the Cleanest Source of Energy
The world’s energy needs are growing with its population. However, achieving a net-zero carbon economy while meeting our growing energy needs requires a larger role for clean, sustainable, and reliable sources. Nuclear is one such energy source.
The above graphic from the Sprott Physical Uranium Trust highlights how uranium is powering one of the cleanest and most reliable sources of energy in nuclear power.
The Cleanest Energy Sources
Although all energy sources have tradeoffs, some are better for the environment than others.
To find the cleanest sources of energy, Our World in Data calculated CO2-equivalent emissions per gigawatt-hour (GWh) of electricity generated over the lifecycle of power plants for different energy sources. This includes the footprint of raw materials, transport, and construction of power plants.
|Energy Source||CO2-equivalent Emissions Per GWh (tonnes)||Type|
|Natural Gas||490||Fossil fuel|
*Emissions from biomass vary depending on the type of fuel combusted.
It’s not surprising that coal, oil, and natural gas plants emit much more greenhouse gases than their renewable and non-renewable counterparts. In fact, emissions per GWh from coal power plants are roughly 273 times higher than nuclear power plants.
Hydropower offers a cleaner and renewable alternative to fossil fuels, however, the concrete and materials used in dam construction contribute to emissions. Furthermore, the decomposition of underwater vegetation in reservoirs also releases methane and carbon dioxide into the environment. Still, emissions per GWh from hydropower are around 24 times lower than coal.
Solar and wind are often the most mentioned energy sources when it comes to the clean energy transition. However, their energy densities are lower than fossil fuels and as a result, they often require more units to generate the same amount of power. For example, generating one GWh of electricity can take more than three million photovoltaic panels, or 412 utility-scale wind turbines. Constructing these massive solar and wind farms adds up to a relatively large material footprint and consequently, GHG emissions.
This is where nuclear power comes in.
Why is Nuclear the Cleanest Source of Energy?
Nuclear power plants use fission to generate electricity without any combustion, avoiding emissions from the process of electricity generation. What’s more, on average, it only takes one typical nuclear reactor to generate one GWh of electricity. The power generation capacity of nuclear reactors is largely due to the high energy density of uranium and nuclear fuel.
According to the U.S. Department of Energy, a single, eraser-sized uranium pellet contains the same amount of energy as 120 gallons of oil or 17,000 cubic feet of natural gas. This allows nuclear power plants to generate large amounts of electricity efficiently, making them one of the cleanest energy sources per GWh of electricity produced.
Nuclear’s Role in the Clean Energy Transition
Nuclear power offers several advantages in the transition to clean energy.
Besides being carbon-free and sustainable, nuclear power is also one of the most reliable and safest sources of energy. In fact, nuclear plants in the United States have a capacity factor of 92.5%, which means that they run at maximum capacity for almost 93% of the time during a year.
As one of the cleanest, most powerful, and reliable sources of energy, nuclear power could play a key role in helping countries achieve decarbonization goals in the fight against climate change.

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.
