Ökogas Vergleich
Climate-Neutral Gas in Germany
Ökogas is regular natural gas whose CO₂ emissions are offset through climate projects. How much of that offset actually reaches the climate depends heavily on certificate quality.
Ökogas ist meistens Erdgas plus CO₂-Zertifikate. Die tatsächliche Klimawirkung hängt stark vom Zertifikat ab.
Key Takeaways / Das Wichtigste in Kürze
- Two variants: Real biogas (from biomass) and climate-neutral gas (regular gas + CO₂ certificate). Most „Ökogas“ tariffs are the second type.
- Verify the offset: A 2024 Correctiv investigation found that 150+ providers could not document where their CO₂ compensation actually goes.
- Trustworthy certificates: Gold Standard (WWF), Verified Carbon Standard (VCS) and the German Grünes Gas-Label set the strictest rules.
- Cost: According to Finanztip, the surcharge is typically €50–250 per year for 15,000 kWh consumption.

Why consider Ökogas?
Lower CO₂
Reduced footprint via offset or biomass
Renewable Option
Biogas from organic waste available
Same Network
Uses existing gas pipes, no new heater
Moderate Surcharge
Typically €50–250/yr extra (Finanztip)
What does „climate-neutral gas“ actually mean?
When you sign up for an Ökogas tariff, your provider still delivers regular natural gas through the same pipes. The difference is administrative: for every kWh you burn, the provider buys a CO₂ certificate. The money funds climate projects — reforestation, renewable energy installations in developing countries, methane reduction.
The German Federal Environment Agency (Umweltbundesamt) calls this voluntary offsetting. The official climate hierarchy: avoid first, reduce second, offset only as a last step.
Is Ökogas actually climate-neutral?
Short answer: often not as climate-neutral as it sounds. A Correctiv investigation from April 2024 examined 150 providers selling „climate-neutral“ gas. For most, the underlying compensation projects could not be verified. Some projects would have happened anyway, without the offset money.
The German Federal Court of Justice (BGH) ruled in 2024 that „climate-neutral“ advertising is only permitted if the compensation method is clearly explained. Vague promises without source documentation are misleading.
Verbraucherzentrale recommendation: If you want real climate impact, reduce consumption first (insulation, lower room temperature, shorter showers), then choose real biogas from waste materials. Pure certificate-based offset is not the same. (Source)
Trustworthy certificates explained
- Gold Standard: WWF initiative since 2003. Strictest checks on additionality, sustainability and social impact.
- Verified Carbon Standard (VCS): Verra international standard. Focuses on measurability and permanence of CO₂ reduction.
- Grünes Gas-Label: German label requiring at least 10% real biogas plus investment into the energy transition.
- TÜV labels: Often only verify origin, not climate effectiveness. Approach with skepticism.
- Self-declared „Klimaneutral“: Without independent audit, treat as marketing.
Cost overview
Based on Finanztip, for a typical household using 15,000 kWh per year:
- Regular natural gas: approx. €1,000–1,300/year
- Climate-neutral gas (CO₂ offset): €50–150/year surcharge — often comparable to regular tariffs because the base price is competitive
- 10–50% biogas blend: €100–350/year surcharge
- 100% real biogas (e.g. Polarstern, Naturstrom): approx. €900–1,000/year surcharge — significantly higher because real biomass is scarce
Frequently Asked Questions
Was ist Ökogas? / What is Ökogas?
Ökogas ist ein Sammelbegriff. Er umfasst zwei Varianten: Biogas (aus Biomasse wie Gülle, Bioabfall) und klimaneutrales Erdgas (normales Erdgas plus CO₂-Zertifikat für Klimaschutzprojekte). // Ökogas is an umbrella term covering two variants: biogas (from biomass) and climate-neutral natural gas (regular gas plus CO₂ certificate for climate projects).
Ist Ökogas wirklich klimaneutral? / Is Ökogas really climate-neutral?
Beim Verbrennen entsteht genauso viel CO₂ wie bei normalem Erdgas. Die Klimaneutralität entsteht durch CO₂-Zertifikate. Correctiv hat 2024 viele Anbieter geprüft und fand bei 150+ Tarifen keine überprüfbare Kompensation. // When burned, ökogas releases the same CO₂ as regular gas. Climate-neutrality comes from certificates. Correctiv investigation (2024) found that 150+ providers could not verify their offset claims.
Welche Zertifikate sind verlässlich? / Which certificates are trustworthy?
Gold Standard (WWF-Initiative) und Verified Carbon Standard (VCS) gelten als am strengsten. Beide prüfen, ob Klimaprojekte zusätzlich sind und tatsächlich wirken. // Gold Standard (WWF) and Verified Carbon Standard (VCS) are considered strictest. Both verify that climate projects are additional and actually effective.
Ist Ökogas teurer als normales Gas? / Is Ökogas more expensive than regular gas?
Laut Finanztip liegt der Aufpreis je nach Tarif und Biogas-Anteil meist bei 50 bis 250 € pro Jahr für 15.000 kWh Verbrauch. Reines 100% Biogas ist deutlich teurer. // According to Finanztip, the surcharge typically ranges from €50 to €250 per year for 15,000 kWh consumption. Pure 100% biogas costs significantly more.
Was ist der Unterschied zwischen Biogas und klimaneutralem Gas? / What is the difference between biogas and climate-neutral gas?
Biogas wird aus Biomasse (Gülle, Bioabfall, Energiepflanzen) gewonnen und ist physisch eine andere Substanz. Klimaneutrales Erdgas ist normales Erdgas, dessen CO₂-Ausstoß durch Klimaschutzprojekte ausgeglichen wird. // Biogas is produced from biomass and is physically different. Climate-neutral natural gas is regular gas whose emissions are offset through climate projects.
Kann ich problemlos zu Ökogas wechseln? / Can I switch to Ökogas easily?
Ja. Der Wechsel ist kostenlos, dauert ca. 10 Minuten online, und die Versorgung wird nie unterbrochen. Du brauchst keine neue Heizung. // Yes. Switching is free, takes about 10 minutes online, and supply is never interrupted. No new heating equipment needed.
Wie erkenne ich seriöse Anbieter? / How do I identify trustworthy providers?
Frag konkret nach Projekt-ID, Standort und Prüfbericht der Klimaprojekte. Polarstern, Naturstrom und Greenpeace Energy sind für strenge Kriterien bekannt. // Ask for project ID, location and audit report of climate projects. Polarstern, Naturstrom and Greenpeace Energy are known for strict criteria.

Tipp für Neuankömmlinge / Tip for Newcomers
In Deutschland können Sie Ihren Gasanbieter frei wählen. Der Wechsel ist kostenlos und die Gasversorgung wird nie unterbrochen. Achten Sie bei Ökogas-Tarifen auf das Zertifikat (Gold Standard oder VCS), nicht nur auf das „klimaneutral“-Etikett.
In Germany you can freely choose your gas provider. Switching is free and supply is never interrupted. For Ökogas tariffs, check the actual certificate (Gold Standard or VCS) rather than relying on the „climate-neutral“ label alone.
