Clearing Up the Smog
Summary
Synapse Energy Economics analyzes and debunks claims made by NERA Economic Consulting regarding the costs of a proposed 65 ppb ozone standard. Synapse finds that NERA inflated compliance costs by over 700% through flawed assumptions on emission reduction requirements, an inappropriate use of 'cash for clunkers' data to price unknown controls, and significant mathematical errors. Synapse's re-analysis suggests annualized costs of $13.6 billion to $21.6 billion, far below NERA's $155 billion estimate. Additionally, the document argues that NERA's prediction of 1.4 million 'job-equivalent' losses is based on a 'black box' model that does not predict actual unemployment and ignores the economic benefits of pollution control investments.
Key insights
- NERA significantly overestimated the amount of NOx emission reductions required to meet a 65 ppb ozone standard, increasing the need for 'unknown controls' to 1,000,000 tons compared to the EPA's estimate of 750,000 tons.
- NERA's cost estimates for unknown controls are based on a single, flawed data point from the Car Allowance Rebate System (CARS), or 'cash for clunkers' program, leading to an extraordinary marginal cost of approximately $500,000 per ton of NOx.
- NERA's total annualized cost estimate of $155 billion contains a math error of approximately $70 billion because it double-counts emissions reductions at coal-fired power plants, treating them as both known and unknown costs.
- Applying Synapse's analysis of coal-fired EGU retrofits and replacements to the EPA's methodology yields an annualized cost of $13.6 billion, which is $1.4 billion lower than the EPA's own Regulatory Impact Assessment (RIA) estimate.
- NERA's claim of 1.4 million lost 'job-equivalents' does not represent actual unemployment, as the NewERA model assumes 'full employment' where no jobs are ever lost by definition.
- NERA's economic model erroneously assumes that pollution control investments 'crowd out' other productive investments, ignoring that such spending can stimulate the economy when there is slack in the market.
- The EPA's 2014 RIA valued the health and economic benefits of a stronger ozone standard at $19 to $38 billion annually outside of California and $2.2 to $4.1 billion per year within California, benefits which NERA failed to account for.
