What Are Scope 3 Emissions?
Scope 3 emissions are indirect greenhouse gas (GHG) emissions that occur throughout a company's value chain, encompassing both upstream and downstream activities. Unlike Scope 1 and Scope 2 emissions, which are directly controlled by the company—such as emissions from owned facilities or purchased energy—Scope 3 emissions arise from sources not owned or controlled by the organization but are influenced by its activities. This category typically represents the largest portion of an organization's total GHG emissions, highlighting the importance of understanding and addressing these emissions for comprehensive sustainability efforts
The Greenhouse Gas Protocol categorizes Scope 3 emissions into 15 distinct categories, each addressing different aspects of a company's operations. These categories include everything from purchased goods and services to end-of-life treatment of sold products. By reporting on relevant categories, companies can gain insights into their environmental impact and identify opportunities for reduction.
Scope 3 Category 12 Emissions: End-of-Life Treatment of Sold Products
Scope 3 Category 12 emissions specifically refer to the GHG emissions associated with the disposal and recycling of a company's sold products once they have reached the end of their useful life. This category encompasses various activities such as waste processing, landfill operations, incineration, and recycling processes. It is particularly relevant for products that generate significant waste, including electronics, plastics, and vehicles, where disposal methods can lead to substantial GHG emissions.
Key elements influencing these emissions include:
Waste disposal methods: Different methods emit varying amounts of GHGs. For instance, landfilling can generate methane, a potent greenhouse gas, while incineration may emit carbon dioxide but also offer energy recovery opportunities.
Recycling processes: The energy used in recycling can lead to emissions; however, recycling often avoids emissions by replacing virgin materials. For example, recycling aluminum saves approximately 95% of the energy required to produce it from raw materials.
Geographical variations: Emission factors can differ by region based on waste management practices and technologies.
Product lifespan and composition: The materials used in a product and their complexity affect total emissions during disposal
Key Industries Affected by Scope 3 Category 12 Emissions
Scope 3 Category 12 emissions, pertaining to the end-of-life treatment of sold products, represent a critical aspect of greenhouse gas (GHG) emissions for many industries. This category encompasses the emissions generated during the disposal and recycling processes of products once they have reached the end of their useful life. Understanding how these emissions manifest in various sectors is essential for companies aiming to reduce their overall environmental impact.
Here, we will explore the electronics industry and how they compute Scope 3 Category 12 emissions. Each section will provide illustrative examples to clarify how these emissions manifest and their broader implications.
Electronics Industry
Scope 3 Category 12 emissions in the electronics industry arise from the end-of-life treatment of electronic products, such as smartphones, laptops, and televisions. These emissions occur when these products are disposed of or recycled after their useful life, and they can significantly impact greenhouse gas (GHG) emissions due to various disposal methods.
Landfilling of Electronic Waste:
Recent studies highlight the significant impact of landfilling on greenhouse gas emissions. For instance, municipal landfills are a major source of methane emissions, accounting for approximately 14.4% of human-related methane emissions in the United States in 2022. The emissions from these landfills were equivalent to the greenhouse gas emissions from over 24 million gasoline-powered vehicles driven for one year.
Moreover, research indicates that organic waste—often comprising a large portion of landfill content—decomposes anaerobically, generating substantial amounts of methane. This underscores the urgency for companies and municipalities to adopt better waste management practices that focus on recycling and responsible disposal methods.
The implications of inadequate e-waste management extend beyond greenhouse gas emissions. Landfills can also lead to soil and groundwater contamination due to hazardous materials found in electronic products, such as lead and mercury.
How companies help: Apple has taken proactive steps to mitigate landfill emissions through its “Apple Trade In” program, which encourages customers to return their old devices for recycling and refurbishment. This helps divert e-waste from landfills, thereby reducing methane emissions associated with improper disposal. Additionally, Apple also employs advanced recycling technologies like the Daisy robot, which disassembles devices to recover valuable materials, further minimizing contribution to landfills.
Incineration of E-Waste
Incinerating electronic waste can lead to significant carbon dioxide emissions and release harmful pollutants into the atmosphere. This method is often used when recycling options are limited, especially in regions without adequate waste management systems. The environmental impact of incineration is profound, as it contributes to climate change and poses health risks to communities near incineration facilities.
According to the Intergovernmental Panel on Climate Change (IPCC), the incineration of municipal waste—including e-waste—results in considerable carbon dioxide emissions, estimated at 0.7 to 1.2 metric tons of CO2 per metric ton of waste incinerated. Additionally, incineration can release various pollutants such as nitrogen oxides (NOx), which contribute to air quality issues and respiratory problems in nearby populations.
How companies help: Dell Technologies has made significant strides in addressing electronic waste through its "Dell Reconnect" program, a partnership with Goodwill Industries. This initiative provides consumers with a free and convenient way to recycle their used electronics while also contributing to community development. The program allows individuals to drop off any brand of computer equipment at over 2,000 participating Goodwill locations across the United States. The program accepts devices in any condition, including computers, monitors, printers, and various accessories. Once collected, Goodwill's trained staff inspects the items to determine whether they can be reused, refurbished, or recycled. This process not only diverts e-waste from landfills but also maximizes material recovery and minimizes incineration. By promoting responsible recycling practices, Dell Reconnect has successfully diverted over 635 million pounds of electronics from landfills.
Inefficient Recycling Processes
