Tokyo 2020 and tropical timber

Dear Ms Heineken and colleagues,

In response to the issues raised regarding the use of tropical plywood at the Tokyo Olympic stadium construction site, we would like to provide you with the following information.

As previously communicated, we were informed that the Tokyo Municipal Government (TMG) and National Government had both verbally agreed to respect the Tokyo 2020 Sustainable Sourcing Code for Timber. As you are aware, this is a document that outlines a framework for the procurement of timber for any projects, services or products under Tokyo 2020’s responsibility. The agreement encompasses the construction of the new Tokyo Olympic stadium.

Since our communication in March, we have also received written confirmation that TMG and National Government will respect the Tokyo 2020 Sustainable Sourcing Code for Timber for competition venues. Please see the written correspondence attached.

Additionally, the IOC has been assured that the wood used for the Tokyo Olympic stadium is PEFC certified timber and meets Tokyo 2020’s Code. We are in direct communication with Tokyo 2020 on this topic.

In the meantime, since the Japanese Sports Council is responsible for construction of the Olympic stadium, we recommend you contact them directly for additional information.

We would like to take this opportunity to thank the non-government organisations for the diligent work they are doing in highlighting sustainability concerns. It is highly appreciated, and we look forward to continued dialogue.

Kind regards,

Christophe Dubi

Dear Christophe,

Tokyo, 10 April 2017

This letter is to follow up the discussion in Project Review held on 1 to 2 March 2017 regarding use of timber for Tokyo 2020 venues.

Tokyo 2020 developed “Sustainable Sourcing Code for Timber” in June 2016 after discussing with experts in different fields including human rights, environment and corporate social responsibility(CSR). In this process, we had opportunities to hear opinions from environmental NGOs, industry groups and others, and asked for public comments as well. The Code therefore reflects diverse points of view from stakeholders. In fact, in the Code, we set the important requirements on sustainability such as legality on harvest and consideration for indigenous rights, while taking the actual business practice of timber trade into account to ensure feasibility. Thus, Tokyo 2020 will procure sustainable timber in accordance with the Code.

In addition, while we developed the Code for Tokyo 2020 itself, we requested Tokyo Metropolitan Government (TMG) and National Government to respect the Code. Thus, TMG and National Government decided to respect the Code in regards to timber used for competition venues of the Games.

In the meantime, the NGOs, who sent the follow-up letter dated on 14 Feb, entertained doubts about legality and sustainability of timber for the Olympic Stadium. However, both Japan Sport Council, contractee of the Stadium, and the contractor that is a joint venture group led by Taisei Corporation have a policy to procure timber in accordance with the Code of Tokyo 2020.

Tokyo 2020 will be working on sustainable sourcing of timber in cooperation with TMG and National Government.
