Creating a Circular Economy/Mitigating Climate Change

この取り組みを通じて目指すゴール: Goal:

Maximize our positive impact (Creating a circular economy)

Minimize our negative impact (Mitigating climate change)


Plans for Initiatives

Electric power, naturally occurring materials, and the planet’s other resources form an essential foundation not only for people’s lives, but for Mercari to continue its business. However, it’s said that humankind is currently consuming our natural resources at a rate 1.6 times faster than they can renew. We believe that creating a circular economy, where we use our limited resources smartly, is a fundamental mission we must complete. 1

Mercari is a marketplace where items that someone no longer needs are passed on to someone else who needs them. That means that the more Mercari users we have, the more able we are to affect positive impact on the environment. From the experience of reusing items and increasing interest in sustainability, people will gradually take on a more sustainable approach to buying, using, and disposing of items, ultimately leading to a new form of production/sales and changes all along the value chain. We believe that by encouraging this change around the world, we not only help achieve a circular economy, but help reduce environmental burden and mitigate climate change.

The concept of “planetary boundaries,” referring to the limits of our earth’s resources, is becoming more widespread. We use the word “planet positive” to express our desire to help solve environmental issues by continuing to generate positive impact on the environment through our business. Mercari will continue to pursue “planet-positive” action to create a world where anyone can demonstrate their value.


Maximize our Positive Impact (Creating a Circular Economy)

This year, we calculated our positive impact exclusively for clothing categories1 for the first time, as the category type with the largest number of transactions on the service, and we found that users’ transactions on Mercari were able to avoid approximately 480K tons of CO2 emissions in 2021. This is equivalent to approx. 200 covered baseball stadiums.
In the last three years, we saw a total of approximately 1.4M tons of mitigated CO2 emissions in the clothing categories alone. We believe that we are steadily contributing to the creation of a circular economy while continuing to grow our business.
The positive impact of our Mercari marketplace business on the environment increases the more users use our service. As a result, the growth of our business itself helps solve environmental issues.

Additionally, users avoided approximately 42K tons of clothing waste (by weight) by listing items on Mercari JP instead of throwing them away.
This is approximately 8.8% of the total 480K tons2 of clothing thrown away yearly in Japan.
By buying and selling clothing that is no longer worn on Mercari instead of throwing it away, users can reduce the burden on the environment and move closer to creating a circular economy.

1. Calculated CO2 emissions avoided on the assumption that items from completed transactions in the Women’s, Men’s, and Kids’ categories for both Mercari JP and Mercari US from April 2019 to March 2021 are used in place of new items, using the LCA method.
Per-unit CO2 emissions for clothing taken from the Ministry of the Environment’s data. (Source:  Ministry of the Environment “Results of Survey on Fashion & the Environment”) Also used the Ministry of the Environment’s data for estimates found in the results of our analysis of CO2 emissions for Mercari US.
 Calculations looked only at the clothing categories as a first survey, since clothing makes up the largest volume of transactions on Mercari and the data was readily available. (Supervised by: Moon Dami, Project Researcher at The University of Tokyo’s Value Exchange Engineering Social Research Division)  As a long-term project, we plan to continue to research the environmental impact of secondhand item use for each manufacturing category.

Minimize our Negative Impact (Mitigating Climate Change)

By 2030, aim to reduce Scope 1+2 emissions by 100% and emissions related to added value for Scope 3 by 51.6% 1
We achieved the 75% reduction in Scope 1+2 that we committed to last year by using carbon offsetting to procure renewable energy-based electricity. We now aim to reduce Scope 1+2 by 100% (compared to our 2020 benchmark) by 2030, by continuing to switch office electricity over to renewable energy and working to reduce Scope 1. Following discussions over several ESG Committee meetings, we set a new target for Scope 3 for 2030, aiming to reduce emissions related to added value by 51.6% from 2020 levels1. We are planning to obtain SBT certification for these targets by June 2023. Leading up to 2030, we will reduce emissions overall for Scope 1+2 and with regard to added value (specific consumption) for Scope 3.

1. Our targets fall under category 1, “purchased goods and services”

Actual amount of emissions in FY2022
In FY2022, Mercari Group as a whole had a GHG emission of about 38,000 tons (see below). Since last fiscal year, we were able to reduce Scope 1+2 emissions by 75% and the intensity of Scope 3 emissions by 10.5%. We will continue to work on various initiatives to achieve our 2030 targets.
- Scope 1: 192 tons
- Scope 2: 1,006 tons
- Scope 3: 37,558 tons
- Total: 38,756 tons

Strategies for Initiatives

    Education: Provide an Environment for Learning Sustainable Behavior

  • We are developing educational programs for elementary to high school students and making them available for free on our education portal site Mercari Education.

    - Let’s Learn About Marketplace Apps and How to Reuse Things
    - “Mercari Observation Notebook”—Workshop Materials for Learning the Value of Belongings and Money
    - Using Marketplace Apps Safely & Securely
    - A Safe and Secure Cashless Society With Merpay
    - Managing Credit and Household Finances From the Perspective of Cash Flow
    - Learn About Sustainable Development Goals (SDGs) Using a Marketplace App

    Minimize our negative impact (future actions)

  • Reviewing how we procure electricity for our offices

  • Reviewing our internal procurement policies

  • Carbon offsetting

  • Popularizing reusing and recycling packaging materials

  • Considering initiatives with suppliers to reduce CO2 emissions
