More companies are looking to go green by buying carbon credits. A big deterrent though is that carbon offset markets are rife with fraud.

XELS, a startup based in Tokyo and Hong Kong, is today launching a blockchain platform for buying and trading carbon credits on Bittrex Global, a leading cryptocurrency exchange.

XELS will provide both businesses and individuals access to a blockchain-based carbon offset platform, initially focused on tokenized voluntary carbon offset credits. These credits are increasingly attractive to companies that want to show consumers they're serious about reducing their carbon footprint.
