The recent OECD General Secretary report includes the Environment and Energy and Carbon Taxes as key areas where more can be done to both help the planet and also build our economies back from the effects of Covid-19.
I would expect to see much more consideration to these issues as they also provide good opportunities for significant capital investment projects across the globe. This was a missed opportunity in the UK Budget 21, but hopefully with COP26 in Glasgow in November, we will see significant steps being taken.
The report, published in January 2021, found that 83% of energy-related CO2 emissions in the countries surveyed are entirely untaxed and that they could generate revenue equivalent to around 1% of GDP if they set carbon rates on fossil fuels equivalent to EUR 30 per tonne of CO2 (a low-end estimate of carbon costs today, and a starting point for price levels required to reach Paris Agreement targets)
