One statistic data has been made public in Barks News(the article is here; Japanese)
According to the article, Radiohead are going to buy Tradable Green Certificates in order to reduce environmental impacts for all gigs of the Japan tour in October. It is estimated that the band will consume electricity approximately 35000kWh in total during all the gigs. However, buying Tradable Green Certificates, the band is expected to contribute to reduce 14,721kg-CO2-relevant emissions. Any other information is not available， however, I hope more details will come out soon.
