It would be hard to imagine pitching any software product as being good for the environment since the entire computer industry is dirty and polluting. Operating system and IoT device software that throttles back a processor into power-saving mode could be an exception.
Another way to look it is that any software which helps us think better or communicate better could help our environment when it's used by people with those goals, in the same way that newspapers and TV helped the environment by propagating facts that people wouldn't otherwise find on their own.
But maybe by relative comparison we could rank them somehow?
For example, some supply chain management software that reduces food spoilage at super markets, might be better for the environment than one that just increases online sales?
