CIOT and IFS Online Debate: What is the role of tax in getting to net zero?

11 Oct 2021

Thursday, 21 October 2021 | 10:00 - 11:30 BST

The UK is committed to reducing net greenhouse gas emissions that arise from UK-based activities to zero by 2050. The EU and other countries have set similar targets, and more will be encouraged to do so at COP26 in Glasgow in a few weeks time. Achieving these targets will require large shifts away from emissions-intensive activity from both consumers and producers.

    - How far can tax and other carbon pricing mechanisms drive this behavioural change?
    - Which works better – taxing carbon emissions, or ‘cap and trade’ schemes?
    - Is the UK’s current mix of green policies effective, or should we aspire to a unified carbon tax?
    - How can we ensure the impact of green taxes is fair?
    - And to avoid importing emissions, do we need a carbon border adjustment mechanism?

These are some of the questions our expert panel considers as we debate the role of tax in tackling climate change.
