All nice ideas, but are any of them policies?
We really need to do something, i'm not convinced telling people not to heat their home, or cool it, not to travel, not to drive, not to eat meat, ie focusing in negative messages is going to work.
Those kinds of messages soon turn the public off.
They could be policies or enablers of larger policies.
Advice does nothing that's why action is needed, no one is going to start taking less holidays etc. The above are all things that could be done without upsetting peoples lives, they work around it whilst still making things greener.
