Meet Your Net-Zero Targets

Durable Carbon Removal Credits: A Key Tool on the Road to Net Zero

Achieving net-zero emissions requires more than just cutting emissions. Durable carbon removal credits offer a complementary and strategic solution.

SIX, in partnership with Carbonfuture, has created a robust, transparent infrastructure that gives access to verified and traceable carbon credits within the Voluntary Carbon Market (VCM). TThis offering, available through BME, combines SIX’s expertise in financial infrastructure with Carbonfuture’s digital monitoring (dMRV) system to deliver a secure and reliable platform for issuers.

SIX Case Study

SIX Sets the Example with Its Own Net Zero Strategy

In 2025, SIX took proactive steps toward climate action by securing a long-term supply of carbon removal credits. The portfolio includes advanced projects such as direct air carbon capture and biochar-based carbon removal.

Thanks to Carbonfuture’s MRV system, SIX is able to track each credit across its lifecycle with full transparency and access to verifiable data.

Frequently Asked Questions (FAQs)

Not yet, but both, voluntary soft law/regulatory frameworks guidance, like the currently revised version of the Corporate Net-Zero Standard of the Science Based Target Initiative (SBTi) and upcoming CDR regulation on national, regional and international level are building pressure.

For example, in Spain, the Real Decreto 214/2025 which came into effect on March 18, 2025, mandating all Spanish-based companies with over 500 employees to publicly report their carbon footprint on an annual basis in a central register and report progress toward net-zero emissions by 2050, in line with the Paris. To meet these net-zero targets, globally, we will need up to 10 gigatonnes of durable CDRs every year by 2050, according to the IPCC, the Intergovernmental Panel on Climate Change.

Adopting early can bring cost benefits in both the short and long term. As carbon markets regulations tighten to meet global climate targets, voluntary and compliance carbon markets are expected to merge towards 2030, the demand for durable carbon removal (CDR) credits is expected to rise, potentially leading to higher prices and even creating the risk of undersupply. By acting now, companies can secure flat prices with long-term multi-year agreements and ensure access to high-quality carbon removal credits.

The approach you take will depend on your industry specific best-practice net-zero goals and overall corporate climate strategy. Key considerations include:

  • To neutralize unavoidable/residual emissions only CDRs can be used from your net-zero target year onwards the latest: Durable carbon dioxide removal (CDR) should address the annually remaining unavoidable emissions that cannot be eliminated through reduction/decarbonization efforts. In order to scale to the volume needed the latest by your corporate net-zero target year, investment in these carbon removal credits needs to be kicked-off today and ideally increased annually.
  • Relevant current carbon reporting frameworks: One of the most relevant best-practice international carbon reporting frameworks, is the Corporate Net-Zero Standard of the Science Based Targets initiative (SBTi), it is very likely that this guidance will increasingly require durable carbon removals to be used to offset at least a certain percentage of your annual residual emissions.
  • Timing: Most companies already investing in CDRs begin with smaller investments and scale up over time to meet interim targets or to prepare for upcoming regulations.
  • Financial planning, long-term budget and strategic procurement strategy: Early long-term investments today can potentially secure lower prices and ensure access to high-quality carbon removal credits that will be most likely short in supply already from 2030 onwards.
  • Strategic contracting approach: We recommend starting with a diversified, multi-pathway portfolio consisting of a range of durable carbon removal technologies spread over different locations and adjusting the volumes of these different technologies over time as regulations evolve.

Currently, various types of voluntary and compliance carbon credits, as well as voluntary durable carbon removal credits, are available for trading.

SIX aims to develop a reliable, standardized, and independent trading platform and thereby make especially durable carbon removal credits more accessible and fungible.  Carbon trading volumes are expected to rise significantly, once quality requirements and financial market infrastructure is standardized.

By building a reliable ecosystem for the durable carbon market together with relevant stakeholders, SIX  aims at enhancing the liquidity of the voluntary carbon market and eventually to establish carbon credits as a new tradable asset class.

BME, as part of SIX, offers so-called permanent or durable (= with long-lasting carbon storage) carbon removal credits through a strategic partnership with Carbonfuture. Carbonfuture’s digital Monitoring, Reporting, and Verification (MRV) system. Ensures comprehensive tracking of the environmental impact and effectiveness of carbon removal activities worldwide, beyond just carbon metrics.

Additionally, SIX and Carbonfuture provide expert guidance to issuers/listed companies and trading clients on developing a multi-year Carbon Dioxide Removal (CDR) credits portfolio out of a diverse range of technologies and deriving from global geographies, such as Biochar Carbon Removals (BCR), Direct Air Capture with Carbon Storage (DACCS) or Bioenergy with Carbon Capture and Storage (BECCS).
