There's always an initiative happening in PowerCo to do some sustainable work with a lot of volunteers
I haven't paid too much attention to this aspect of the company.
We have recylcing bins everywhere with clear signage and there are periodic efforts to audit what people's habits are in each of the offices, results being published on the internal intranet. There are car chargers available to employees for use and a massive amount of solar panels were installed recently on the roof spaces. I think they are doing a pretty good job.
