Many companies that is using bitcoin and the blockchain particularly some ICO's recently are being launch involving the betterment, improvement or something that will sustain our environment but is it enough to do its part or what it promises in its vision and mission? because the next tough part after the launch is how can they implement it effectively using bitcoin or the blockchain? are the world ready for it?
Bitcoin and blockchain, as being mostly digital technologies, have quite little to do with the environment, aside from the negative impact of PoW (which is actually exaggerated). So, the short answer is no, even with all the possible positive effects it would be not enough to counter all the negative influences from other industries. But Bitcoin and blockchain might help a bit, fiat payment systems are consuming way more electricity than Bitcoin mining, so with technologies like Lightning Network efficiency can be significantly improved. Blockchain might also have some impact, like for example with optimizing shipments, but it remains highly theoretical.
