This paper looks into how to track carbon footprints in homes using a technology called NILM. The goal was to find a way to measure how much a household impacts the environment. The researchers created a model using NILM to track carbon footprints. They tested this by calculating a carbon footprint using NILM. The results showed that NILM can accurately track a household's carbon footprint. This means NILM technology can help people understand how their actions at home affect the environment.
