Rakuten Announces Results of Japan’s First Circularity Evaluation at Rakuten Open 2022
– Reducing the amount of CO2 absorbed in a year by forests equivalent to approximately 156 tennis courts through initiatives such as reuse and recycling –

Rakuten Group, Inc. (“Rakuten”) introduced the system at the “Rakuten Japan Open Tennis Championships 2022” (“Rakuten Open 2022”) held at the Ariake Coliseum and Ariake Tennis Park Court. announced the evaluation results of “circularity” (circularity) from resource procurement to disposal as the first “circularity evaluation” (Note 2) for a sporting event in Japan (Note 1).
At Rakuten Open 2022, in order to address essential environmental issues, we want to reduce the environmental impact of tournament operations and create an environment where sports can be enjoyed in a rich natural setting. In cooperation with Recotech Co., Ltd. (hereinafter “Recotech”), which continues to make advanced efforts such as the development and operation of the circulation platform “POOL”, we have implemented various initiatives to face global environmental issues.

(Note 2) “Circularity evaluation” is a measure of the “circularity” of corporate initiatives formulated by the World Business Council for Sustainable Development (WBCSD) and 30 global companies.・It is a framework for self-evaluation.
(Note 3) Visually represents the input and output of indicators related to “circularity” (resource input, energy consumption, waste generation, CO2 emissions, etc.).
■ Results of “Rakuten Open 2022” “Circularity Evaluation”
The results of the “Circularity Evaluation” at “Rakuten Open 2022” are as follows. (Note 4)
・Material circularity rate: 48%
Circular inflow rate: 36% / Circular outflow rate: 60%
・CO2 reduction effect through circular efforts: 35,709 kg-CO2 At “Rakuten Open 2022”, efforts are being made to ensure the sustainable operation of the tournament by using and reusing reusable materials, and thoroughly sorting and recycling waste with “ECO STATION by Rakuten” waste sorting boxes installed in the venue. was carried out. As a result, the “circular outflow rate”, which indicates the recyclability of discharged resources, was 60%. The “Circular Inflow Rate”, which indicates the circularity of the resources invested in the operation of the Games, was 36%, and the “Material Circularity Rate”, which takes each of these elements into
consideration, was 48%.
In addition, the sustainable initiatives implemented at “Rakuten Open 2022” have led to a reduction of 35,709 kg of CO2 emissions compared to what would have been otherwise (Note 5). This is equivalent to the amount of CO2 absorbed in a year by a forest equivalent to
approximately 156 tennis courts (Note 6).
At the time of the next operation, we will actively work on activities to increase the “circular inflow rate” such as expanding the use of reused materials, switching to materials using recycled materials, and procuring wood and ingredients produced using sustainable methods. , we aim to achieve a higher level of material circularity. In addition, in the future, we will aim to circulate even higher quality resources at venues for various competitions, not just tennis.
 Rakuten will continue to promote initiatives for a sustainable future for all people through various activities.
(Note 4) The definition of each term and the calculation method of the ratio are as follows.
Material Circularity Rate: Weighted average of circular inflow rate and circular outflow rate for a product, business unit, or company as a whole
Circular inflow rate: [mass of renewable inflow (sustainably grown and harvested biomass material) + mass of non-virgin inflow (material procured from reused or recycled materials rather than new)] / sum of all inflow masses × 100
Circular outflow rate: Total mass of outflows where products and materials have complete resource recycling potential and are actually collected and resource recycling is achieved / Total mass of all outflows × 100
(Note 5) See the table below.

(Note 6) Calculated based on the assumption that 1m2 of forest absorbs 0.88kg of CO2 per year, converted into a double scoot (approximately 261m2).
■ Comment from Recotech
At a large-scale sports event, there is no precedent in Japan for evaluating circularity from the perspective of inflow and outflow at the event in accordance with the WBCSD guidelines. In that respect, we believe that the circularity evaluation at Rakuten Open 2022 is not only an achievement for a single company, but also a great achievement for Japan.
We hope that “Rakuten Open 2022” will become the best practice for sustainable initiatives in large-scale events and lead the way for events in a recycling-oriented society on a global scale.
We will also use the resource circulation platform “POOL” to introduce management methods that generate less waste and implement optimal resource circulation by procuring materials with low environmental impact, making it the standard for event management in Japan. I would like to continue
■ Initiatives at Rakuten Open 2022
At “Rakuten Open 2022”, a garbage sorting box “ECO STATION by Rakuten” will be set up in the venue, and five types of waste generated from this event (1. Combustible 2. PET bottles 3. PET bottle caps 4. Garbage 5. Separate into lunch bags). Efforts were made to reduce CO2 emissions by constructing recycling loops for each item as much as possible, recycling them, and reducing the amount of incineration. PET bottles are reborn as PET bottles, and PET bottle caps are recycled as recycled resin and reborn as tennis-related goods. Lunch bags are also recycled resin, which can be used as a raw material for other plastic materials. Food waste was transported to a methane fermentation facility and recycled into electricity and organic fertilizer.

 In addition, the circularity of the event was evaluated by
visualizing and analyzing the process from resource procurement to disposal at the event using the resource circulation platform “POOL” developed by Recotech.

Furthermore, from October 1st (Sat) to October 9th (Sun), including the qualifying rounds, Rakuten Energy Co., Ltd. will use
forest-derived CO2 generated from the electricity used to run the tournament. We offset 16 tons (Note 8) through the J-credit (Note 7), realizing environment-friendly operation of the Games.
As an attempt to allow fans to contribute to the sustainable operation of the tournament, 146 “Rakuten Open 2022 Green Tickets” were sold through “Rakuten Tickets.” The price of the purchased green ticket will be used for the cost of this activity, excluding fees.
(Note 7) The “J-Credit Program” is certified by the government as “credits” for the amount of CO2 emissions reduced through the introduction of energy-saving equipment and the use of renewable energy, and the amount of CO2 absorbed through appropriate forest management. system. “Forest-derived credits” are certified by the government as “credits” for the amount of CO2 absorbed through appropriate forest management such as thinning.
(Note 8) Compensating for CO2 (= carbon) that is generated in daily life and corporate activities, no matter how hard you try, with other activities (tree planting, forest protection, development of renewable energy, etc.) is called “carbon offset”. In other words, it is a way of thinking that aims to compensate for the generated CO2 and reduce the amount of CO2 emissions to virtually zero.
■ Background of implementation
・Why will Rakuten Open 2022 address the environment?
On the occasion of Rakuten’s 25th anniversary, Rakuten is promoting “Let’s create the future of sports together – A BETTER FUTURE TOGETHER -“, an initiative to solve social issues such as the global
environment together with athletes, and “Rakuten Open 2022”. We also carried out activities to leave an environment where people can enjoy sports in rich nature for the next generation.
・ About “Let’s create the future of sports together – A BETTER FUTURE TOGETHER -”
Taking advantage of the 25th anniversary of its founding this year, Rakuten launched the “Go Green Together” project, calling for an environmentally friendly and green future. We have opened a special site “Let’s create the future of sports together – A BETTER FUTURE TOGETHER -” that thinks and disseminates what we can do for you. Through this initiative, we aim to create a future where sports can be enjoyed while being considerate of the environment, and to realize a society where everyone can enjoy sports in their own way.
that’s all
