“Circular Economy Principles – Quantifying the Additional Greenhouse Gas Savings Potential of Products Covered under Ecodesign”

Authors

Marie Baton, Michael Scholand

Overview

In December 2015, the European Commission adopted an ambitious Circular Economy Package designed to accelerate Europe's transition towards a circular economy, thereby boosting global competitiveness, fostering sustainable economic growth, and creating new jobs. The authors conducted a study to estimate potential greenhouse gas emission savings when circular economy principles are applied to all ecodesign and energy labeled products. The circular economy principles modelled in this analysis were: improved recyclability, extended service life, service economy approach (e.g., product leasing, pay-per-unit-of-service) and improved refurbishment. This paper presents results for each of the five product categories. Consumer electronics had the largest greenhouse gas savings potential, particularly for recyclability and extended service life. And, for service economy approach, the study also found the average efficiency of the leased products was the most critical parameter influencing emission savings. Building on these findings, this paper offers suggestions for next steps – including developing product metrics, stimulating recycled materials markets and developing more detailed market feasibility studies.


“Measurement of automatic brightness control in televisions – critical for effective policy-making”

Authors

Michael Scholand, Marie Baton, Robert Harrison

Overview

Display luminance (“brightness”) is the largest energy consuming function in televisions and monitors. Subjective research on televisions in households has shown that displays can be dimmed when room ambient light levels are naturally reduced, to achieve lower product power consumption while not diminishing the quality of the viewing experience. This energy-saving feature is most commonly called ‘automatic brightness control’ (ABC) and works by dimming the display’s brightness in relation to the room illuminance.

CLASP funded research to develop a novel and repeatable approach to the measurement of television power consumption and display luminance versus controlled ambient illumination under ABC control. This paper describes and illustrates the test setup and data logging equipment to capture the television’s power consumption and screen luminance characteristics under a full range of ambient light levels, from <2 lux to >300 lux. The test method provides insight into how the ABC algorithm is written in the television software, with some televisions progressively reducing screen brightness as the ambient lighting levels are lowered, and others simply having one large step reduction at a low level of room illumination. From an energy perspective, the software that progressively reduces screen brightness will achieve more energy savings. CLASP is submitting this test method to the IEC and CEN/CENELEC for consideration as an update to relevant European and international test standards.

“India’s experience in implementing strategic schemes to enhance appliance energy efficiency & futuristic integrated policy approaches to adopt most efficient technologies”

Authors

Archana Walia, PhD, S. Sundaramoorthy

Overview

India’s projected electricity demand is 2499TWh by 2030. As the government of India (GoI) works to save its primary energy sources, combat climate change, and provide 24x7 power to all, energy efficiency (EE) has become vitally important. This paper reviews the GoI’s strategic approaches that made efficient appliances more accessible to consumers and unlocked the potential for energy management at operational level. It discusses successes and lessons from energy savings models and policy approaches, lays out options to overcome the barriers, and proposes integrated policy approaches to adopt and implement the most efficient technologies and the potential impact on energy savings and global climate change. This paper establishes the potential to reduce the electricity demand in 2030 by at least 10% of projected overall demand through integrated policy approaches. This would also result in an emission reduction of 210 Mt CO2.        


“Designing Cookstove Labels to Influence Consumer Behavior in Ghana”

Authors

Michael Spiak, Yang Yu, Ranyee Chiang, Paula Edze, and Ruth Essuman

Overview

In support of the Global Alliance for Clean Cookstoves, the Energy Commission Ghana, and Kantar Public Ghana, CLASP is helping design cookstove labels to influence consumer behaviour in Ghana. Three billion people in low- and middle-income countries use cooking fuels and technologies that pose health risks associated with household air pollution, and environmental impacts associated with GHG emissions and deforestation. In response, efforts are underway across the globe to transition households to cleaner, safer, and more fuel-efficient cookstoves. The government of Ghana is planning to launch a new national performance standards and labeling (S&L) program for improved cookstoves (ICS), in an effort to increase the uptake of ICS across their urban and rural populations. This paper discusses the development of the Ghana improved cookstove label, specifically two components: informed visual label design, and setting performance thresholds for label tiers. The paper includes the approach and methodology for both components, as well as preliminary results from consumer research on preferences and behavior change in response to cookstove labels, and analysis and recommendations for label tiers.


“Global Lighting Challenge: Changing the World through Public- Private Partnerships”

Authors

Allison Kimble, Hans Alarcón, Chad Gallinat, Peter Bennich

Overview

The Clean Energy Ministerial (CEM) and the US Department of Energy (DOE) launched the Global Lighting Challenge (GLC) in December 2015 to accelerate the global transition to energy efficient lighting. Lighting accounts for 15% of global electricity consumption and 5% of global greenhouse gas emissions. The GLC is a race to reach cumulative global sales of 10 billion high-efficiency, high quality, and affordable lighting products, such as light-emitting diode lamps through public –private partnerships. Since its launch, the GLC has built a volunteer PPP of more than 50 governments, manufacturers, retailers, and expert groups working together to accomplish its 10 billion product goal. In support of CEM, DOE, and the Swedish Energy Agency, this paper explores a theory of change for international campaigns by discussing the difficulties and benefits of building a volunteer coalition on a global scale that seeks to accelerate the transition to energy efficient lighting.

Workshop

“Smart Testing of Energy Products (STEP) - Addressing Gaps in Test Standards”

Organizers

CLASP, the Environmental Council of States, the European Environmental Bureau, & Topten

Date

Tuesday afternoon, 30 May

Overview

Following extensive testing by our team, this workshop will focus on gaps and failures in existing harmonized test standards for televisions, refrigerators and dishwashers. We invite the broad summer study audience to contribute and exchange ideas on how to improve standardized testing, keeping the balance between more representative and robust tests - while maintaining the important aspects of reproducibility and comparability.
