Ruth Lea: UK Climate Policies Are Futile & Shockingly Expensive

Higher energy costs result in squeezed household budgets, disproportionately so for the less well-off, and worsened business competitiveness while higher business costs are passed through to households in the form of higher prices for goods and services.

In previous notes for The Conservative Woman, I have attempted to show that the UK’s climate change policies, involving uniquely aggressive energy decarbonisation policies, are futile gesture politics. The UK is accountable for just 1 per cent of global CO2 emissions, whilst other major economies, not least China (nearly 30 per cent of global emissions) and India (over 6 per cent) are powering ahead with coal-fired power stations, with resultant increases in CO2 emissions.

The UK’s decarbonisation policies are, however, not just futile in terms of controlling global CO2 emissions, they are also expensive. Stating the obvious, the decarbonisation of energy supplies, whether for electricity generation, heating or transport, involves replacing relatively inexpensive carbon-based fossil fuels by relatively expensive non-carbon based sources (including renewables and nuclear power). Moreover, the increased costs are very considerable. This short note focuses on the costs originally envisaged at the time of the Climate Change Act 2008, with some follow-up developments.

Suffice to say, these extra energy costs are borne by users, whether households or businesses, as well by taxpayers. The higher costs result in squeezed household budgets, disproportionately so for the less well-off, and worsened business competitiveness. Moreover, insofar as the higher business costs are passed through to households in the form of higher prices for goods and services, household budgets are doubly affected.

Costs of the Climate Change Act 2008

As I discussed in a previous note, the UK introduced the Climate Change Act (CCA) in 2008, which unilaterally committed the UK to reduce GHG (greenhouse gas) emissions by 80 per cent of 1990 levels by 2050. The Department of Energy and Climate Change (DECC) provided a cost-benefit analysis, the ‘impact assessment’, for the Act. 

DECC estimated that the total costs over the then 43 years to 2050 amounted to £324-404billion (in discounted present value terms). Moreover, DECC qualified their estimates by saying the ‘figures presented are a partial measure of the long-run costs of tackling climate change and are based on estimates of the reduction in GDP over the period to 2020’, and, they added, the ‘figures do not include the full range of costs, in particular the short-term transition costs’. So even these huge figures were under-estimates.

The DECC also helpfully provided estimates of the ‘average annual cost’ to 2050, amounting to £14.7-18.3billion. The UK’s population was around 66million in 2018, whilst the number of households was nearly 28million. Very approximately, these annual averages translate into £220-280 per capita and £525-655 per household.

Meanwhile the climate benefits of the CCA in reducing GHG emissions, and thus avoiding ‘dangerous anthropogenic global warming’, over the period to 2050 were estimated to be £404-964billion, with the upper bound assuming effective global action. Suffice to say, effective global action is singularly absent. And, insofar as there would be any mitigation of dangerous global warming, the benefits would be global not national, with the UK, arguably, getting little in return from its enormous investment.

There have been several studies, official and non-official, into the costs of the Climate Change Act since its implementation. A very comprehensive exercise was undertaken by Lord (Peter) Lilley in 2016, using data from DECC (absorbed into the Department of Business, Energy and Industrial Strategy in July 2016), the Office for Budget Responsibility (OBR) and the Climate Change Committee(CCC). He concluded that ‘the average cost of decarbonising electricity to meet the CCA’s targets was or will be per household (in 2014 prices): £327 in 2014, £584 in 2020, £875 in 2030, £1,390 by 2050’. Not only were these numbers very substantial, note that they principally cover electricity decarbonisation, not heating and transport.
