Blockchain technology in general, and crypto mining industry in particular, at somewhat extent have made negative impacts on the global climate due to more energy consumption, which also leads to more green house gases emitted into the atmosphere.
So, it's promising to see how the Zero Carbon project solve the issue related to Climate change and blockchain industry.

very old project, whose ICO has not yet taken place I really stopped watching him a couple of months ago, and as I understand it, nothing has changed here. What is new, especially important for the project? Will it take place at all? When?

Firstly, I'm excited. Secondly I admire the Zero Carbon team's professional approach and business flexibility. The team is able to adjust to market conditions and current trends, it's one of the best things  typical for the experienced real world business.
