Perhaps the Man at Number 10, Doesn't Speak to the Man at Number 11?

The official residence of the UK's PM is 10, Downing Street. The Chancellor of the Exchequer lives next door at Number 11. The PM has notional responsibilities for the Cop26 meeting in Glasgow on climate change. The Chancellor, in his budget speech, has lowered the rate of air passenger duty for short haul domestic flights and continued the freeze on fuel duty for cars (https://www.theguardian.com/politics/live/2021/oct/27/autumn-budget-2021-rishi-sunak-spending-review-borrowing-live-updates?page=with:block-617943248f08ea671ec0b18d). The last things we need to do, if the UK is to reduce its 'greenhouse gas' emissions, is to encourage both short haul air flights and fossil fuel-powered car use. Domestic flights generate more emissions per passenger per mile than longer trips. Emissions are highest at take off and landing. There are also easy alternatives to short haul flights such as travelling by train. The failure to raise more duty on petrol and diesel also reduces the incentive to go electric. Perhaps the Chancellor is trying to drive us to drink? He has also reduced the tax on beer and cider.
