Resale Impact

The luxury brand products we sell, including watches, jewelry, and bags, are often passed from one generation to the next, thanks to carefully selected materials and advanced manufacturing techniques. We believe that the redistribution of such products through resale reduces the environmental impact of society as a whole (environmental value) and reduces the environmental impact associated with new resource extraction and manufacturing.

Valuence encourages merchandise circulation through brand resale, providing a mechanism to maximize the useful life of a product, rather than ending its role after a short lifespan. We have defined Resale Impact as a metric to quantify and disclose the environmental value created by brand resale across society based on an avoided emissions calculation methodology. We call this metric Resale Impact.

By disclosing this indicator, we contribute to the understanding and wider adoption of the concept and calculation method of avoided emissions. Our clear communication of the environmental value of resale services to consumers encourages environmentally conscious choices and behavioral change.

Avoided Emissions

Avoided emissions is a quantified environmental value to society as a whole, arising from the provision of products and services that reduces GHG emissions in society. Studies are underway in Japan and abroad on the definition, methods of calculation, and means of disclosure. Several guidelines have been established in this context. However, as opposed to Product Category Rules (PCR), detailed and standardized calculation rules for avoided emissions have not yet been established in many industries, and no unified methodology exists in the resale sector.

Since the Valuence resale services cover a wide variety of products—watches, jewelry, and bags, etc.—and we engage in hundreds of thousands of transactions per year, we do not believe it is practically feasible to conduct a separate and precise assessment for each transaction.

Given the circumstances, we use a calculation methodology based on actual transaction data retained internally and designed for ongoing practical use. Our methodology does not rely on the assumption that resale uniformly replaces the purchase of new products. Rather, we assess changes in environmental impact in terms of extended product life.

The methodology for calculating avoided emissions on this page is based on the resale service avoided emissions calculation framework developed by ZEROC Inc., an LCA consulting firm. We have asked Professor Ichiro Daigo of the Research Center for Advanced Science and Technology, The University of Tokyo, to conduct an outside expert peer review of our methodology. After consideration, we incorporated certain matters raised into our methodology, the results of which we communicated to the peer reviewers.

Scope of Coverage

  • Services: Brand resale services
  • Product categories: Watches, Jewelry, Bags, Cases, Accessories, Apparel, Shoes

Environmental Footprint Baseline and Valuation Assessment Target

Fashion items that are repeatedly resold over the useful life of the product and used by multiple users

Calculation Unit

Per year of use

Assessed Impact Area of the Valuation Target

  • Climate change
  • Water consumption

Target Life Stage

We consider the full life cycle from raw material procurement and manufacturing, distribution, use, and disposal. The use phase to be assessed includes the resale process (maintenance, repair, and transportation for resale). We exclude from the calculation (cutoff) indirect impacts associated with store lighting, construction, and indirect departments.

Scenario

Years of Use

Watches, jewelry, and bags account for a large percentage of resale sales value. Therefore, we conducted a questionnaire survey (3,947 valid responses) of customers whose purchases were completed at domestic purchasing locations, using the data to determine the number of years of use.
*For other categories, we base useful life on a literature review.

Resale Frequency

We calculate resale frequency based on a scenario that takes into account the useful life and average sales period of the product.

Precious Metals

Watches and jewelry incorporate precious metals, which are raw materials with a particularly large environmental impact. Accordingly, we determine a metal content ratio for each major material by referring to the labeling regulations of the Japan Jewelry Association and official data. The percentage of recycled raw materials at the raw material procurement stage is based on official statistical data.

Avoided Emissions Calculation Methodology

Contribution Ratio

Our avoided emissions methodology assesses the effectiveness of resale services in avoiding environmental impacts associated with the manufacture and disposal of new products.
Therefore, we use a contribution ratio of 100%, as the main cause of the reduction is the resale service itself.

Data

Primary Data

  • Product weight: We record the actual weight during the resale process for products that can be measured. When actual measurement is difficult for a certain product category, we make calculations based on weight data using representative values calculated by sampling and measuring the weight of multiple products by category and material to calculate an average value.
  • Transportation: We use sales results to determine the ratio from transportation route classifications between purchase and sale in Japan and overseas.

Secondary Data

  • IDEA v3.3 (National Institute of Advanced Industrial Science and Technology)
  • Academic literature
  • Official statistics

Uncertainties and Limitations

  • We use secondary data since none of the products we resell are manufactured in-house, which means we are unable to obtain primary data on many of the raw materials and energy inputs actually used in the manufacturing process. Accordingly, our calculation results entail a certain degree of uncertainty.
  • While we resell a wide variety of products, this methodology calculates the environmental footprint of a representative product under each product category, which we apply to individual products. For this reason, detailed material composition and energy consumption at the manufacturing stage may not fully reflect the actual conditions.
  • While we establish a uniform value scenario for the number of years of useful life, regardless of the number of resales, the actual number of years of useful life may decrease as the number of resales increases.
  • We assume that the timing of disposal on the baseline and the timing of first resale for the target merchandise is the same. However, the actual timing of the sale of the merchandise may have been accelerated due to the existence of resale services. To produce a more valid assessment, we should collect primary data on users who do not use resale services and incorporate that data into the baseline calculation.
  • This methodology is intended to make the calculation of each transaction and annual avoided emissions simple in practical terms. Some formulas use averaged values of actual data as constants. Therefore, the results may differ from calculations based solely on the actual data of individual transactions.
  • For gold, which contributes significantly to avoided emissions, database limitations and the inability to trace the country of origin of the gold used in a product prevent us from accounting for the differences in emission factors and recycling rates by country of production.
