for example: Compare the Labour and Conservative Manifestos of the last election for the environment, obviously a lot has changed but this is what I go by. I would also like to point out before I get negged or fingered, that I voted for neither of those parties in the last election lol
Conservative:
£640M for a Nature/Climate fund
Plant 75,000 acres of trees* a year by end of next parliament
Labour
£400 Billion for a National Transformation Fund
improve the energy efficiency of 27 million homes in the UK
build 7,000 offshore wind turbines**
build 2,000 onshore wind turbines**
22,000 football pitches worth of solar panels
(not sure if the turbines etc are part of the £400 Billion spend or not, it doesn't say)
Which one looks like over promise and under deliver to you ?
That's just one policy that I have chosen, obviously anyone can sit and cherry pick the good and bad from both manifesto's as I am sure you are aware, I am just using that particular section as an example
* Someone pointed out that it works out at a tree being planted every 4 seconds, 24 hours a day, 365 days a year - don't think they will hit that target tbh
** heard/read somewhere that turbines are not all they are cracked up to be, one such study on cost/return on investment is here
