The Role of Carbon Pricing in Achieving Net-Zero

Addressing the global challenge demanding a multitude of solutions. Among these, carbon pricing stands out as a key policy instrument, promising to drive decarbonisation across industries. But can it truly deliver on its net-zero potential? 

Carbon pricing puts a price on greenhouse gas emissions, making high emissions activities more expensive. The aim is to incentivise businesses and individuals to reduce their emissions and shift towards low-carbon alternatives. Carbon pricing takes two primary forms. The first is a carbon tax levied on each tonne of greenhouse gas emissions. This provides a predictable carbon price signal. The second is a cap-and-trade, where a limit (or cap) is set on total emissions, and emission allowances are created and traded. This creates a market for emissions, with the price fluctuating based on supply and demand. Carbon pricing is often considered a cost-effective way to reduce emissions, as it allows the market to find the most affordable alternatives. It can also be applied across various sectors of the economy, providing flexibility in achieving emissions reductions. It harnesses the power of market forces to drive decarbonisation, minimising the need for regulations. 

Carbon pricing plays a crucial role in achieving net-zero in three ways. By making polluting activities more expensive, carbon pricing incentivises emissions reductions and encourages businesses to invest in cleaner technologies and processes. This creates a financial incentive to reduce emissions across the economy. Carbon pricing mechanisms (particularly carbon taxes) can also generate substantial revenue. This revenue can be used to fund further climate action (such as investing in clean technologies and low-carbon solutions), support a just transition for affected workers and communities, or even reduce other taxes. Lastly, carbon pricing can promote behavioural change for both businesses and consumers. It motivates companies to develop and deploy cost-effective, low carbon alternatives to fossil fuels. By increasing the cost of carbon-intensive activities and products, carbon pricing can influence consumer behaviour, encouraging individuals to make more sustainable choices.

Europe is involved in international efforts to promote carbon pricing and carbon markets. Established in 2005, the EU Emissions Trading System (ETS) serving as the world's first emissions trading system. The EU has also implemented a Carbon Border Adjustment Mechanism (CBAM) to ensure that imported goods are subject to a carbon price equivalent to that faced by domestic producers including through the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO). The EU is also working to develop a framework for international carbon crediting mechanisms, which could allow countries to offset their emissions by purchasing credits from projects that reduce emissions elsewhere.

While it's not a magic bullet, carbon pricing can a critical part of driving decarbonisation and achieving net-zero targets. By carefully designing and implementing mechanisms and coupled with other essential policies, carbon pricing can accelerate the transition to a cleaner, more sustainable future.
