TOKYO -- Japanese trading house Mitsubishi Corp. will start selling renewable electricity certificates that buyers can use as offsets for their energy consumption, Nikkei has learned. Murata Manufacturing, an electronic components maker and major Apple supplier, will be the first to receive a certificate. This will be Japan's first case of a so-called virtual power purchase agreement. Under the scheme, Mitsubishi will actually build a solar power plant and deliver generated electricity to the utilities market, and separately sell renewable energy certificates to those who want to use them as offsets.
