Researchers at the University of Groningen in the Netherlands have estimated that billions of tons of carbon from fossil fuels have been stored in long-lasting human-made items, such as gadgets, building materials, and infrastructure, over the past 25 years. This “technosphere” has grown at a rate faster than fossil fuel emissions, with 400 million tons of carbon added annually. However, when these objects are discarded and incinerated, they release carbon emissions into the atmosphere, making it a “ticking time bomb.” The study suggests that nearly 30% of fossil carbon is trapped in rubber and plastic, while another quarter is in bitumen used in construction. The researchers emphasize the need to manage the disposal of these items in a more climate-friendly way, such as designing products for recyclability and longevity, and reducing consumption. Landfills can act as a long-term carbon sink if managed well, but the authors acknowledge that they often have negative environmental impacts. Ultimately, the solution requires a shift in consumer behavior and a focus on reducing waste and promoting sustainable consumption.
Your gadgets double as carbon sinks, at least for now.
