The German Government is preparing to introduce a green gas quota as part of its new building and heating policy framework (Gebäude-Modernisierungsgesetz, GMG), which could have a positive impact in the amount of clean, renewable gas in the country’s current energy system. Instead of relying on fossil gas, the measure would require gas suppliers to integrate a progressively increasing share of renewable and low carbon gases into the natural gas network.
What makes this proposal important is that it focuses on the gas supply itself, rather than asking individuals to replace their heating systems all at once, creating a fairer and more manageable path. It’s a way to cut emissions across the whole country, without putting extra pressure on society, and that remains aligned with climate targets.
From the perspective of the e-NG Coalition, the introduction of a green gas quota represents a timely and strategically important step in accelerating the decarbonization of the gas system. A well-designed quota can provide the market-based framework needed to boost investment across the value chain and support the scale-up of renewable and low-carbon gases in a way that is socially fair, economically efficient, and fully aligned with climate objectives. By creating steady demand for renewable gases, the quota helps reduce emissions, strengthens energy security, and protects households from sudden or costly changes.
According to the e-NG Coalition's Global Project Tracker, more than 150 renewable gas projects are currently under development worldwide, reflecting increasing industrial momentum and investment interest. In parallel, the European Union has set clear targets to expand renewable energy use across sectors under the Renewable Energy Directive (RED III, EU 2023/2413), including the introduction of RFNBOs (renewable fuels of non-biological origin) and specific targets for the industry and transport sectors. Together, these developments indicate that renewable gases are ready for large-scale deployment, if supported by policy frameworks.
However, to make this system truly future proof, it is essential to include a dedicated sub-quota for RFNBOs. These fuels, such as e-methane, can scale to the volumes needed for full decarbonization but a clear RFNBO sub-quota can really ensure that they can grow fast enough to meet climate targets, attract investment, and become progressively more affordable over time.
In practice, this could mean a cleaner energy system, stronger long-term security of supply, and a transition that remain sboth effective and fair for everyone.
On 24 February 2026,the German government published an Eckpunktepapier (key points paper) outlining the main elements of the proposed GMG. The document, endorsed by the Federal Cabinet, sets out the direction of the reform but does not yet constitute a legally binding act. It provides the basis for a formal draft law (Gesetzentwurf),expected to be led by the Federal Ministry for Economic Affairs and Climate Action (BMWK) and the Federal Ministry for Housing, Urban Development and Building (BMWSB), in coordination with other relevant ministries.
The preparation of the draft law represents a critical phase for defining the operational design of the green gas quota, including key parameters such as the overall ambition level, the trajectory over time, and the treatment of different renewable gas pathways. It is at this stage that core structural elements, including the potential introduction of a dedicated sub-quota for RFNBOs, can be most effectively embedded in the legal text. Early policy choices made during drafting will shape not only the environmental integrity of the framework, but also its ability to provide clear and credible investment signals.
Once finalized, the draft law will be adopted by the Federal Cabinet and submitted to the German Bundestag for parliamentary consideration. During the first reading, the proposal is introduced and referred to the relevant parliamentary committees, where the most substantive work takes place. Committee deliberations involve detailed examination of the legal provisions, expert hearings, and negotiations between political groups, and represent a key moment for refining the design of the quota. It is here that amendments can be introduced to strengthen the level, scope, and implementation modalities of an RFNBO sub-quota, as well as provisions related to sustainability criteria, certification, and system integration.
Beyond primary legislation, the implementation phase will be decisive. The GMG is expected to rely on secondary legislation, including ordinances and technical regulations, to define detailed parameters of the quota system, such as compliance mechanisms, verification procedures, and reporting obligations. This stage provides an additional opportunity to operationalize and fine-tune elements such as an RFNBO sub-quota, including its interaction with existing EU frameworks and associated certification systems.
The initiative reflects Germany's broader effort to reduce emissions in the buildings sector, one of the country's most carbon-intensive segments. Previous reforms under the Building Energy Act (Gebäudeenergiegesetz, GEG) introduced the requirement that newly installed heating systems must operate with at least 65% renewable energy. While this approach provided clear signals for electrification, it also highlighted challenges related to upfront investment costs, infrastructure readiness, and social fairness.
The GMG introduces a different approach by targeting the fuel mix (the actual supply of gas into the system) rather than prescribing specific technologies for individual households. The government argues that this shift remains fully compatible with Germany's climate targets, noting that "decarbonization of the gas supply is an essential component of achieving climate neutrality by 2045." By placing obligations on energy suppliers rather than households, the reform aims to deliver emissions reductions at scale while easing the financial and administrative burden on consumers.
From the Coalition's perspective, this shift can strengthen climate action, but only if the quota is designed to create meaningful additional demand for renewable gases. A quota that is too low, or insufficiently differentiated, risks being met largely through existing biomethane volumes without accelerating the deployment of other renewable gases needed for long-term climate neutrality.
The green gas quota is expected to establish a minimum and progressively increasing share of renewable gases in the natural gas system. Compliance would be ensured by gas suppliers and potential network operators, supported by certification and traceability systems aligned with EU sustainability rules, including RED III.
The climate impact of the quota depends heavily on its detailed design. A low initial quota level risks limiting the mechanism's effect, as existing biomethane volumes could meet early requirements without stimulating new investment. While biomethane plays an essential and immediate role in reducing emissions, an undifferentiated approach risks delaying the development of other critical solutions (particularly RFNBOs, such as renewable hydrogen and e-methane) that are necessary to achieve climate neutrality at scale.
For this reason, the e-NG Coalition highlights the importance of a balanced and differentiated framework, including a dedicated RFNBO sub-quota. German industry associations BDEW and DVGW have emphasized that a well-calibrated quota can "accelerate the market ramp-up of renewable gases and contribute meaningfully to climate protection in the buildings sector." A differentiated approach also provides clarity for investors and maintains a level playing field across pathways, allowing each solution to develop according to its maturity and long-term potential.
The proposal is closely aligned with the Renewable Energy Directive (RED III, EU 2023/2413) and the ongoing EU Gas Package negotiations, which together set the rules for how Europe will expand renewable and low-carbon gases in the coming decades. RED III establishes binding targets for renewable energy across all sectors — including clear minimum shares for RFNBOs in both industry and transport — and requires every Member State to put in place the systems needed to certify, trace, and account for these fuels. The EU Gas Package complements this by creating a dedicated market framework for renewable gases, including rules for network access, guarantees of origin, and cross-border trade. By translating these EU-level objectives into a national demand-side measure, the German initiative helps turn European climate goals into concrete market signals that producers and investors can act on.
This alignment also matters for practical reasons. RED III requires that renewable gases, including RFNBOs, to meet strict sustainability and greenhouse gas reduction criteria, and that all transactions are recorded in EU-wide databases to ensure transparency and avoid double counting. By anchoring the quota in these certification and traceability rules, Germany ensures that only genuinely climate-friendly gases count toward its targets. At the same time, harmonized EU rules make it easier for renewable gas projects in different countries to connect to German demand, supporting the development of cross-border markets and integrated European supply chains: a more reliable, competitive, and scalable market that can deliver the volumes needed for long-term decarbonization while keeping costs under control for consumers.
RFNBOs such as e-methane can be introduced into the energy system immediately because they are fully compatible with the gas infrastructure Germany already has. E-methane is chemically identical to fossil methane, which means it can move through the same transmission and distribution pipelines, be stored in existing underground storage facilities, and be used in today's boilers, CHP units, industrial burners, and household appliances without any technical adjustments. For end users, nothing changes in how they heat their homes or use gas day to day — the gas simply becomes cleaner over time.
If adopted, the quota would represent a structural shift in Germany's approach to decarbonizing the buildings sector. By creating stable demand for renewable gases, it would support project development, facilitate the integration of existing infrastructure, and enable the emergence of cross-border supply chains. The measure would also strengthen energy security by diversifying supply sources and reducing exposure to fossil fuel price volatility. Its impact would extend across the entire value chain — from electrolysis and methanation capacity to CO₂ sourcing, transport, and storage — shaping investment decisions for years to come.
The proposal has generated debate across the political spectrum. Some parties have raised concerns about the risk of fossil lock-in if renewable gas supply does not expand quickly enough. In contrast, other parties have focused on cost impacts and supply predictability. Despite these differences, the government maintains that the GMG is climate-aligned, arguing that "a renewable gas quota ensures that emissions fall across the entire system, not only at the point of installation." The e-NG Coalition agrees — provided that the mechanism is designed to stimulate new, scalable renewable gas production rather than relying on existing volumes.
Recent geopolitical developments have highlighted Europe's structural vulnerability to fossil fuel markets. In this context, renewable gases, including e-methane, offer a unique opportunity to combine decarbonization with energy security. As mentioned before, we have identified more than 150 e-methane projects worldwide, with a production pipeline expected to reach approximately 1.3million tons by 2031, confirming that regional supply chains are already emerging.
Unlocking this potential requires reliable and technology-specific demand signals. Without such signals, projects risk being delayed or failing to reach final investment decisions, despite their technical maturity and strategic relevance. A well-calibrated quota system can help overcome cost gaps, drive economies of scale, and ensure that the transition remains affordable while safeguarding investment certainty.
Industry stakeholders have broadly welcomed the proposal. A coalition of 21 companies and associations representing different segments of the gas value chain recently expressed support for the introduction of a quota mechanism, noting that it provides a predictable and market-oriented framework for investment. Stakeholders emphasize that the transition from voluntary uptake to regulated demand creation is essential for scaling renewable gas production and enabling long-term offtake agreements.
However, stakeholders also highlight that the effectiveness of the mechanism will depend on its final design. A quota that does not differentiate between pathways risks limiting long-term scalability and delaying the development of RFNBOs. The e-NG Coalition stresses that technology-specific demand signals are essential to ensure that emerging solutions, such as e-methane, can reach final investment decisions and scale intime to contribute meaningfully to climate targets.
In a significant legislative step running parallel to the GMG, the German parliament passed a bill on the 23rd of April, requiring that 10% of all fuel used inland-based transport (covering both road and rail) be derived from renewable hydrogen by 2040. The law establishes a stepwise trajectory, with annual sub-targets set for the years leading up to that deadline, creating a progressively tightening compliance schedule for fuel suppliers and obligated parties across the transport sector.
This is a notable policy development in its own right: transport is one of Europe’s most carbon-intensive sectors and among the hardest to decarbonize, and a binding, technology-specific mandate for green hydrogen-based fuels sends a strong investment signal to electrolyser manufacturers, hydrogen producers, and logistics operators alike. But its significance extends beyond transport.
Taken together with the green gas quota proposed under the GMG for the buildings sector, this legislation reveals a broader and more deliberate direction in German energy policy: rather than decarbonizing sector by sector through technology mandates applied to end-use equipment, Germany is increasingly turning to fuel-side obligations, requiring that the molecules flowing through existing infrastructure become cleaner over time.
Germany now has a strategic opportunity to establish a robust, pragmatic, and forward-looking framework that accelerates decarbonization while positioning the country as a leader in the development of green gas markets. By ensuring that the green gas quota is differentiated, scalable, and investment-friendly, policymakers can create the conditions for long-term success and avoid the risk of locking in suboptimal pathways. A balanced and climate-aligned quota can support the scale-up of renewable gases, strengthen energy security, and contribute meaningfully to Germany's climate and energy objectives.
