Trade Tools for Climate: Transatlantic Carbon Border Adjustments

Overview
As the EU carbon border adjustment mechanism (CBAM) makes its way through the legislative process in Brussels (part of the European Union’s hallmark Fit for 55 package), the United States has also introduced its version of a carbon border adjustment. In early June, U.S. senator Sheldon Whitehouse (D-RI) introduced the Clean Competition Act (CCA). This legislation follows an earlier version introduced in July 2021 and would establish a carbon border adjustment as a U.S. trade tool to incentivize deeper decarbonization among foreign producers while protecting U.S. firms. The bill is cosponsored by Democratic senators Chris Coons (D-DE), Brian Schatz (D-HI), and Martin Heinrich (D-NM). Although Senator Kevin Cramer (R-ND) has indicated that the legislation could gain some bipartisan interest, that is unlikely to occur if the package includes a domestic carbon price.
The primary objective of the CCA is to penalize producers of more carbon-intensive production processes, in turn giving U.S. firms with comparatively fewer embodied emissions a competitive edge. The CCA proposes a domestic price on domestic emissions intensity as well as a border adjustment mechanism for importers into the United States. There are 25 different sectors listed in the bill, including prominent carbon-producing industries such as petroleum, natural gas, fertilizer, paper, cement, glass, and iron and steel. Exporters of these industries would face fees based on their emissions intensity when entering the United States.
Q1: How does the Senate-proposed CCA compare to the EU-proposed CBAM?
A1: The main difference between the U.S. CCA and the EU CBAM is in its calculation of the carbon border price. The European Union has established the EU emissions trading system (ETS) since 2005, and the CBAM would become an international complement to the domestic carbon market. The price for the EU carbon permits is around 84 euros as of early July. Imposing a price on carbon is often regarded as a foundational step in ushering in deeper decarbonization, yet the United States has not implemented a federal price on carbon to date. The CCA, however, would establish a price on carbon, which would enhance compliance with WTO rules that forbid discrimination.
Another key difference between the U.S. CCA and EU CBAM is which countries would be implicated, although data challenges remain. In 2021, UK-based think tank E3G produced a report estimating the impact of the EU CBAM on imports. E3G found that the CBAM would most significantly impact China and Russia, while U.S. exports would be relatively unexposed. However, the European Parliament’s proposed expansion of the CBAM to cover chemicals would significantly alter this picture, as U.S. chemical exports are comparatively much more emissions-intensive than their EU equivalent products.
Q2: How reliable is available data in assessing carbon-intensity of foreign produced goods?
A2: There is a lack of reliable public data on emissions intensity by industry and country, let alone firm-specific emissions data. Greenhouse gas emissions are often collected at the broad sectoral level, while firm-based carbon accounting remains difficult and cumbersome. For example, there is not sufficient public and reliable data that would accurately capture the emissions intensity of foreign produced goods covered by the U.S. carbon border adjustment proposal. Furthermore, the ability of countries to gather and report emissions intensity data varies significantly, complicating the implementation of a border adjustment. Overall, the development and deployment of technology that could make carbon accounting more transparent lags significantly behind market demands.
In assessing fees to levy on imports from abroad, the CCA relies on economy-wide emissions averages from foreign countries. However, carbon accounting without sufficient specificity or “granularity” risks disincentivizing decarbonization. For example, producers of a certain good may invest in greener technologies but end up paying the same fees if the industry is subject to sectoral averages. Since this approach fails to capture existing decarbonization efforts, it does not reward companies for progress achieved and could ultimately discourage investment in renewable energies and sustainable technologies.
Regardless of carbon accounting approaches, whether firm-, sector-, or economy-based, gathering sufficiently specific data remains a cumbersome hurdle for policymakers to overcome in order to implement a fair and transparent carbon border mechanism.
Q3: What are the primary sources of imports for the covered categories of goods?
A3: Gathering accurate data about the emissions intensity of specific sectors—let alone specific firms—in foreign economies remains a significant challenge for policymakers and the private sector to overcome. Nevertheless, trade data from USITC illustrates the top five exporting countries to the United States based on CIF Import Values for 25 sectors by a 6-digit NAICS code referenced in SEC. 4694 of the bill. The figures below visually highlight a selection of these 25 sectors with import data from 2021.
