Germany is missing its European Climate targets by 2030 around 255 million tonnes of CO₂ equivalents. According to current calculations, the additional costs required for this could amount to up to 38.3 billion euros amount to. The building and transport sectors are primarily responsible – while the energy and agriculture sectors are already exceeding their targets.
The current Projections Report 2026 of the German Environment Agency (UBA), produced by a consortium of the Oeko-Institut, Fraunhofer ISI, Prognos, M-Five, IREES, and the Thünen Institute, paints a nuanced picture of German climate policy: mathematically, the national climate target for 2030 – minus 65 percent greenhouse gases compared to 1990 – remains narrowly achievable. The European obligations under the Effort Sharing Regulation (ESR) are against it clearly missed. This means the buffer from previous years' projections is now almost exhausted.
The starting position: stagnation instead of a turnaround
In 2025, German greenhouse gas emissions fell by just 0.1 % from the previous year to 649 million metric tons of CO₂ equivalents. Although recorded emissions have roughly halved over the past 20 years, this pace is not sufficient to cover the remaining distance to 2030.
The 2026 projection data show a reduction of 62.6 % by 2030 compared to 1990. To achieve the legally mandated target of 65 %, approximately 30 million metric tons of CO₂ equivalents still need to be reduced. According to the UBA, this means that the cumulative annual emissions between 2021 and 2030 can only be met by the narrowest of margins. The remaining buffer is therefore only 3.8 million metric tons. Even minor shifts in economic growth, subsidy budgets, or energy prices could completely deplete this buffer.
In the long term, the gap is even more pronounced. Instead of the 88 % reduction required by law by 2040, the report projects only 80 %. Net greenhouse gas neutrality by 2045 will also not be achieved with the measures currently being implemented—mathematically, approximately 212.5 million metric tons of gross emissions would still remain.
The legal framework for this reporting obligation is the Federal Climate Change Act, which prescribes fixed sector budgets and a control procedure via the independent Expert Council on Climate Issues – we have that KSG as a binding roadmap to climate neutrality already classified in detail.
Why the gap is growing: Buildings & transport as problem children
The sectoral breakdown reveals a clear pattern: wherever electricity from renewable sources directly replaces fossil combustion, emissions fall predictably. Wherever electrification stalls, the emissions balance remains stubborn.
building sector
By 2030, there will be a gap of 110 million tons of CO₂ equivalents compared to the statutory reduction path. While electricity-powered heat pumps now dominate in new buildings, in absolute terms, 81 percent of German heat generation continues to be fossil-fuel-based, meaning via oil and gas. We have analyzed how the PV obligation under Section 106 of the GModG, taking effect in 2027, and the transition from the previous GEG to the new GMG will impact this balance in two separate articles: Solar mandate starting in 2027 pursuant to Section 106 GModG and From the GEG to the GMG.
transport sector
With an excess of 187 million tons of CO₂ equivalents by 2030, the transport sector is the most stubborn stumbling block. The main reason is sluggish electrification: the projected passenger car stock will only number around seven million battery-electric vehicles by 2030 – the statutory target was 15 million. Short-term bright spots such as the nearly 78 percent increase in new registrations of pure electric cars in June 2026 change little about this as long as electric cars make up just a good four percent of the total stock.
Industry
Emissions fell by 5 % in 2025, primarily due to declines in production in the iron and steel industry. UBA President Dirk Messner himself explained this to the Handelsblatt: The decline was primarily due to weak economic performance, not a genuine shift toward low-emission production.
Energy industry
Despite the share of renewable energy in electricity consumption now reaching nearly 60 %, electricity generation still produced 167 million metric tons of greenhouse gases in 2025—due to increased use of coal, a lower emissions trading price, and delays in offshore wind expansion. In 2025, coal- and natural gas-fired power plants together accounted for 38 % of electricity consumption. This share is expected to decrease thanks to the recently enacted StromVKG as part of the Network packets even rise further.
Agriculture & Waste Management
These two sectors, on the other hand, are already falling below their budgets today—an indication that targeted progress is possible when the instruments take effect.
What the cost estimate actually means
Here, a conceptual clarification is worthwhile, which often gets lost in the public debate: It is not to avoid a penalty and not concerning the purchase of EU ETS 1 certificates, as acquired by industry and the energy sector in European emissions trading.
The 255 million tons refer to the Effort Sharing Regulation (ESR) - that part of the EU Climate Action Regulation that covers precisely the sectors that previously not Covered by the EU ETS are: transport, buildings, agriculture, as well as smaller industrial and energy installations. If a Member State exceeds its annual ESR budget, it must purchase excess emission allowances—so-called Annual Emission Allocations (AEAs)—from states that stay below their own budget. This is a compensation mechanism within the EU effort sharing, not a sanction in the strict sense.
Since there is no liquid, publicly viewable market price for AEA itself, cost estimates are provisionally based on the price path of the EU Emissions Trading System (ETS 1). According to the Handelsblatt Research Institute, a metric ton of greenhouse gas is expected to cost between 60 and 150 euros there in 2030. On this basis, the following cost range results for closing the German ESR gap:
| Lower limit (€60/t) | Upper limit (150 €/t) | |
| Previous assumption (ESR gap: 224 million t) | €13.4 billion | €33.6 billion |
| Current UBA data (ESR gap: 255 million t) | €15.3 billion | €38.3 billion |

The difference from the previous year's estimate shows: the gap is growing faster than previous assumptions suggested – a signal that, without additional measures, the additional costs are likely to continue to rise. We have provided a detailed classification of the various CO₂ pricing systems – ETS 1, ETS 2, and ESR in comparison – in our basic article on CO₂ pricing In summary.
Political reaction: Climate Protection Program 2026 & lingering issues
The federal government has responded to the missed targets with the 2026 climate action program, which was adopted by the cabinet on March 25, 2026. Among other things, it contains additional measures such as CCS retrofits for waste incineration plants and the expansion of hydrogen power plants.
The independent expert council for climate issues assesses the Federal Government's need for action as remaining high in view of the increased failure to meet targets. Deutsche Umwelthilfe also considers the program to be inadequate, pointing to a ruling by the Federal Administrative Court from January 2026 that had already obligated the Federal Government to make improvements—with a further lawsuit announced in the event that the gaps identified in the projection report are not closed.
The uncertainty surrounding the... EEG Amendment 2027 out. The law must enter into force on January 1, 2027, because the EU Commission's state aid approval for the existing EEG expires at the end of 2026. However, the draft bill is still undergoing inter-ministerial coordination; a cabinet decision originally targeted for the summer of 2026 has been postponed several times. BEE President Ursula Heinen-Esser warned of a “break in the thread of the energy transition” in the event of further delays. At the same time, the PV market is currently continuing to grow: the German Solar Energy Association (BSW) reported market growth of nine percent over the past twelve months compared to the previous year.
The real lever: sector coupling instead of pure generation expansion
The 2026 Projection Report makes a structural point clear that often gets lost in the public debate: the gap does not arise primarily from the expansion of renewable generation. At just under 60 percent of electricity consumption, that is well advanced. It arises where electrification meets sluggish infrastructure – in the building stock, the vehicle fleet, and also in the power system itself, which cannot integrate the growing volatile loads from heat pumps and e-mobility in a grid-serving manner without sufficient flexibility.
Regulatory requirements start precisely at this interface, such as ESG Scoring of real estate, which is increasingly translating climate targets into binding valuation criteria. Whether Germany will meet its sector budgets in the future thus depends less and less on additional generation capacities than on how quickly Battery storage, energy management systems and flexible loads interact in buildings, vehicle fleets, and industry.
Conclusion: What about Germany's climate targets for 2030?
According to the 2026 projection report, the national climate target for 2030 remains mathematically achievable, but the buffer for it has shrunk to a minimum. By contrast, the European ESR obligation will be clearly missed with a gap of 255 million tons of CO₂ equivalents, which is foreseeable to incur tens of billions of euros in additional costs for Germany to purchase emission allowances from other member states. The targets for 2040 and 2045 are already being missed. Two strategic decisions will be crucial for the coming months: the concrete implementation of the 2026 climate action program in the buildings and transport sectors, and the further progress of the 2027 EEG amendment, which will help determine investment security in the only sector that has been compliant with targets so far—the energy industry.
Frequently asked questions about Germany's climate targets up to 2030
What is the Effort Sharing Regulation (ESR), and how does it differ from the EU Emissions Trading System (ETS 1)?
The ESR regulates emission reductions in sectors not covered by the EU Emissions Trading System (ETS 1)—primarily transport, buildings, agriculture, and small-scale industrial and energy installations. If a member state exceeds its ESR budget, it must purchase emission allowances (AEAs) from states with a budget surplus. ETS 1, on the other hand, concerns large industrial and energy installations, which directly use certificates acquired there.
How high could the additional costs be for Germany?
According to current calculations based on the 2026 UBA projection data, between 15.3 and 38.3 billion euros by 2030 – depending on how the underlying CO₂ price path (60 to 150 euros per ton) actually develops.
Which sectors are responsible for missing the targets?
Especially buildings (gap of 110 million t CO₂ eq. by 2030) and transport (187 million t CO₂ eq.). Agriculture and waste management fall below their targets, while the energy sector remains above the target emission level despite progress.
What does this mean for the climate policy of the coming years?
In the short term, the implementation of the 2026 climate action program in the buildings and transport sectors will determine the extent of the ESR gap. In the medium term, a great deal depends on the 2027 EEG amendment, which must enter into force by January 2027, but is still stuck in inter-ministerial coordination, thereby creating investment uncertainty in the energy sector.
