In a bid to reach its goal of reducing emissions by at least 55% by 2030, the EU has introduced the world’s first carbon border tax, officially known as the Carbon Border Adjustment Mechanism (CBAM). The new regulation will place a tariff on certain goods imported from non-EU countries with less stringent environmental policies, effectively placing a price tag on the carbon emissions associated with the production of those goods.

CBAM aims to tackle the problem of carbon leakage, which occurs when companies relocate their high-emission production abroad to evade domestic environmental policies, such as the EU’s Emission Trading System. CBAM is thus an attempt by one of the world’s largest trading blocs to level the playing field and incentivise foreign producers and economies to adopt more ambitious climate action. It will take effect from 1st October 2023 with a transition period and will be fully operational from 1st January 2026. The goods being regulated in the first period are considered to have the highest emissions and risk of carbon leakage. These include cement, iron, steel, aluminium, fertilisers and electricity.

While CBAM represents a bold step towards aligning global trade with emissions reduction goals, it also raises critical questions regarding climate justice. Under this mechanism, low-income countries could face significant pressure to rapidly transform their industries to meet the EU's environmental standards. Such transformations could be particularly challenging, given that low-income countries often lack the necessary resources and infrastructure. Moreover, these countries have historically contributed little greenhouse gas emissions while bearing the brunt of climate change impacts. To address these equity concerns, measures such as a phased introduction of CBAM with initial exemptions and differential pricing for low-income countries could ease short-term economic burdens, while technology transfers and capacity building from high-income countries could assist their low-income counterparts in adopting cleaner production methods in the long run. Additionally, high-income countries meeting, or even exceeding, their Paris Agreement commitments to mobilise climate finance could provide crucial resources for low-income countries to transition to a low-carbon economy.

Do you think CBAM is the great equaliser for trade and climate action, or will it perpetuate climate injustice? Let us know in the comments.
