The research – carried out as part of Epson’s Turn Down the Heat campaign with National Geographic to promote the protection of the world’s permafrost – reveals a worldwide switch across all laser and inkjet models could cut energy emissions to 52% of current levels. This is the equivalent to taking about 280,000 cars off the road for a year. It also showed that inkjet technology can be up to 90% more energy efficient than laser technology depending on the type of printer and usage patterns. Road to net zero The study identified that to keep the world on track to achieve a net zero carbon future, the energy consumed globally by all appliances must fall dramatically, with one potential pathway including an average reduction on 2020 levels of approximately 25% by 2030 and 40% by 2050. Tim Forman, Senior Research Associate at University of Cambridge, comments: “This research project has proven that a pathway to a net zero future for printing is possible, as long as people switch to the most energy efficient products both in homes and offices and we reduce the carbon associated with manufacturing these products. We hope to now see more efforts to advance eco-friendly technologies across the appliance sector – including TVs, washing machines, fridge freezers and ovens – to reach net zero emissions by 2050. “It is crucial that we continue to improve the energy efficiency of appliances – and reduce the energy required to produce appliances – to avoid the worst climate change scenarios.
