Scope 3: where does e-waste fit into the emissions inventory?

Understanding Scope 3 in greenhouse gas emissions

Scope 3 corresponds to all indirect emissions that occur in the value chain, including everything from the extraction of raw materials to the disposal and treatment of waste. It is the most comprehensive and challenging scope to monitor and manage, as it involves various stages and partners throughout the life cycle of products and services.

The importance of e-waste in the emissions inventory

Electronic waste, or e-waste, is one of the wastes that has a significant impact on Scope 3 emissions, mainly because incorrect disposal and treatment releases greenhouse gases and toxic substances, as well as requiring energy-consuming recycling. Considering e-waste in the inventory makes it possible to identify opportunities for reducing emissions and making processes more sustainable.

How is e-waste accounted for in Scope 3?

In the emissions inventory, e-waste is included in the categories related to final waste management, which are part of Scope 3. This includes emissions caused from the transportation to the final destination of electronic equipment that is no longer used. Assessing this flow requires a detailed survey of the volumes of waste generated and the methods used for disposal and recycling.

Challenges in accounting for e-waste emissions

There are several difficulties in measuring e-waste emissions, such as the lack of precise data on the amount collected and processed, as well as the variability of recycling processes which may or may not be efficient in terms of gas emissions. It is also complex to trace the final destination of waste, especially that which is disposed of irregularly.

Strategies to reduce emissions from e-waste

To minimize the impact of e-waste in Scope 3, it is essential to implement strategies such as extending the useful life of electronic equipment, reusing and repurposing components, and encouraging proper recycling. These actions help to reduce waste generation and indirect emissions associated with disposal.

Benefits of including e-waste in the emissions inventory

In addition to improving the quality of the inventory and providing a more complete overview of emission sources, considering e-waste in Scope 3 makes it possible to identify circular economy initiatives, support environmental policies and positively influence the production chain, contributing to the mitigation of climate change.
