Forthcoming) Adapted from Andrae, A.S.G, & Corcoran, P. M. (2013). Emerging Trends in Electricity Consumption for Consumer ICT. In 2014 scrapped mobile phones, smartphones, and tablets could add 0.234 million tonnes scrap. Annual global municipal solid waste generation is 1.3 billion tonnes.

Add Location of Production of Screen, IC, PCB, and type of Screen for more sophistication. Robust criteria from other ER could be added. Use stage scenario not clear. Comments on RESPONSIBLE DESIGN: More options needed for certain questions due to diversity of phones. Usage of Bioplastics should be added as a criterion. Fully separable packaging materials unclear. Pure material stream needs to be defined according to some standard. ERs range from satisfyingly transparent (understandable which input gives a certain output) to black box (not fully clear how the ER works) VDF/TF new eco-rating is a very good basis/concrete tool to finish the Recommendation in 2013 in a unified and transparent manner.

Add choices which help the vendor to reflect the reality of the upstream and downstream in a better way Issue 1: Differences between vendors CO 2 e scores based on LCA and CO 2 e scores based on locked ER metrics. Issue 2: Difference in CO 2 e score for same model for different ER Found a 20% difference in CO 2 e scores for different ER Life Cycle section for the same phone model Spread of problem not investigated

For specific usage details, refer to the Typesetting Standard. 8 Overall issues for vendors Clarity It should be totally clear for individual vendors (manufacturers) how a certain ER is obtained. Transparency E.g. it shall be understood explicitly which CO 2 e score gives a certain ER for the corresponding Specification (e.g. 40 kg CO 2 e gives 2.1 for Basic LCA). Validation Clarify how the validation is done for each Specification (e.g. Responsible Design) and Criteria (e.g. Proportion of Pure material stream which can be separated)

For specific usage details, refer to the Typesetting Standard. 9 Requirements & Suggestions Requirements Add LCA elements for further diversification between devices. Any Criterion which cannot be easily validated needs to go. Each operator should make totally clear for individual vendors (manufacturers) how a certain ER is obtained. Suggestions: Fully calculated examples of some imaginary phones will help for black-box oriented ER schemes Analyse further differences between vendors CO 2 e scores based on full LCA and CO 2 e scores based on locked ER metrics (e.g. kg CO 2 e/touch screen area). Analyse further differences between vendors models in between different ERs.
