The global compliance carbon markets, key components of environmental sustainability efforts, are projected to surpass $800 billion in value this year, marking a 5% year-over-year increase despite reduced trading volumes due to the Ukraine conflict.
This growth is partly attributed to reforms aimed at enhancing the effectiveness of these markets, although concerns about energy affordability and security temper this optimism.
Carbon markets operate on the principle of trading carbon credits. There are two primary types: compliance and voluntary markets. Compliance markets are created by regulatory frameworks at national, regional, or international levels, while voluntary markets are based on individual or corporate choices to trade carbon credits. These credits are used to offset greenhouse gas emissions by purchasing them from entities that reduce or remove emissions.
The European Union’s Emissions Trading System (ETS), established in 2005, is a notable example of a compliance market, operating under a cap-and-trade system. This system allocates emission allowances to regulated entities, which can then trade these permits. The EU’s ETS remains the largest carbon market globally in terms of volume and value. However, its dominance is declining, with its share of global carbon market futures and auctioned volumes falling to 75% in 2023, down from 90% in 2017.
In contrast, China launched the world’s largest ETS in 2021 in terms of emissions coverage, addressing around one-seventh of global fossil fuel-related emissions. Despite challenges, this market is reportedly achieving its goals.
Meanwhile, the UK’s carbon market is facing difficulties. Citi analysts have predicted a significant drop in UK carbon permit prices due to a lack of ambitious reform in the country’s emissions trading system. Additionally, the UK government’s recent policy revisions, aiming to ease the supply cut of allowances, have led to a substantial decrease in the cost of pollution rights.
Despite their widespread adoption in developed economies, the effectiveness of carbon offsets in combating climate change is increasingly questioned. Critics argue that these offsets often serve as excuses for continued emissions rather than genuine climate action solutions. The UN Environment Programme (UNEP) warns against complacency induced by carbon credits, emphasizing the need for a comprehensive shift away from carbon reliance.
An alternative to carbon offsets, Renewable Energy Credits (RECs), is gaining attention. Unlike carbon offsets that signify a carbon sequestration action, RECs represent a share in a renewable energy source, thus directly supporting the development of renewable energy infrastructure. This approach is seen as more conducive to promoting sustainable energy solutions.
