Analysing of the impacts of the revision of Ecodesign and Energy Label Regulations for household dishwashers by using a stock model

摘要

This paper projects European households' stock of dishwashers and explores possible measures to accelerate adoption of more energy-efficient products. Europe is experiencing an increase in the sales of household dishwashers and this trend is expected to become more relevant in the coming years. The consequent rise in energy consumption and greenhouse gas (GHG) emissions can be reduced if consumers are motivated by environmental awareness and options on the market to buy more choice of energy-efficient household dishwashers. In 2010, Europe introduced Ecodesign and Energy Label requirements aiming at regulating this sector and now the time has come for their revision. Additionally, the newly released Energy Label Framework Regulation ((EU) 2017/1369) mandates a rescaling of the current level to return to an A to G scale. The stock of dishwashers is projected using the data for EU-28 and estimated savings in households' electricity and water consumption, GHG emissions and consumer expenditure have been calculated for four different scenarios. Using a stock model, this study shows the effectiveness of revising both the Ecodesign and Energy Label Regulations for dishwashers and proposes several options within the newly released Energy Label Framework Regulation ((EU) 2017/1369). At the EU-28 level, estimated savings in households' electricity consumption of 2.0 TWh/year (corresponding to a reduction of 0.67 Mt CO_(2eq)) and 15 million m~3 of water per year in 2030 could be expected if the Ecodesign and Energy Label Regulations for household dishwashers are revised and implemented accordingly. Additionally, we presented several scenarios that measures could bring benefits to the consumers (EUR2015 0.72 billion in 2030).
