Not, but pressure is building. For example, in Switzerland, the Climate and Innovation Act came into effect in 2025, mandating all Swiss-based companies to achieve net-zero greenhouse gas emissions by 2050. To meet these net-zero targets, we will need up to 10 Gigatonnes of carbon removal annually by 2050, according to the IPCC.
Early adoption offers both short- and long-term financial benefits. As regulations tighten and compliance markets expand toward 2030, demand for durable carbon removal (CDR) credits will increase—and so will prices. Acting early helps companies lock in lower prices and secure access to high-quality supply.
There’s also a strong business case for climate leadership. A recent study by the World Economic Forum (Source) found that companies with higher emissions than their industry peers trade at an average discount of 37.5%—highlighting the financial risk of inaction.
It depends on your sector, your net-zero targets, and your broader climate strategy. Key factors include:
- Your residual emissions: Durable CDR should cover the emissions you can’t eliminate through emission reductions.
- Applicable frameworks: Standards like the Science Based Targets initiative (SBTi) increasingly call for durable removals to neutralize residual emissions.
- Timing: Some companies start small and scale over time to align with interim targets or upcoming regulations.
- Budget and procurement strategy: Early purchases can lock in lower prices and secure access to high-quality credits.
We recommend starting with a portfolio approach and adjusting as your targets and regulations evolve.
Certain types of voluntary and compliance carbon credits and voluntary durable carbon removal credits can be traded now. Trading volumes are projected to significantly increase as trusted, standardized, and independent trading platforms mature and become more accessible.
Once fully developed, the credits will increase the liquidity of the carbon market and eventually become a new tradable asset class.
The voluntary carbon market, especially the voluntary durable carbon removal market, is projected to grow exponentially by 2030 and is regarded as a financially advantageous investment.
