Zero Carbon Homes - Watering Down but Common Sense

The announcement that the definition of a zero carbon home now excludes emissions from the likes of cooking appliances , entertainment systems etc. has enraged many but actually, there's a deal of pragmatism tucked in here. Was it ever realistic to expect builders and developers to second guess home-owners' behaviour. I think not. Of course, this does now put the pressure back on educators, opinion formers, appliance manufacturers etc. but so be it.
