1) What are the targets and timescales for carbon reduction, waste reduction and water use?
Ambition of targets matters, particularly given the increasing urgency of carbon and other GHG reductions and these are more variable than you might think. For example, Amazon's timescale for reaching net zero carbon emissions across its whole operation is 2040. Microsoft has stated that it will be carbon negative by 2030.
Datacentres and some factories are highly water intensive depending on cooling technology and location. Many datacentres are built in areas like Arizona because of the availability of wind and solar power, but these are regions of high water stress. Vendors should be trying to reduce their water impact with the aim of water positivity by a certain date.
Companies should also be aiming for as close to zero waste to landfill as possible, with the target being to recycle and reuse not just material like paper and plastic but also servers, components and other electronic waste.
