The Bottom Line
Copenhagen has not achieved carbon neutrality in 2025 as originally promised, but the Danish capital’s journey reveals something more valuable than a met deadline: a blueprint for honest, science-based urban climate action. With 75-80% emissions reduction since 2005 and 0.7 tonnes CO₂ per resident in 2023, Copenhagen has quietly shifted focus to its ambitious “Climate Plan 2035” while pioneering technologies that could define the future of sustainable cities worldwide. As Le Monde’s analysis reveals, the reality check exposes both remarkable achievements and the brutal complexity of eliminating the final 20-25% of urban emissions.
The Current Reality: Unprecedented Progress, Strategic Pivot
Copenhagen’s 2023 Emissions Data
According to official municipal data released in November 2024, Copenhagen recorded 470,968 tonnes of CO₂ emissions in 2023. This equals 0.7 tonnes CO₂ per resident.
The city achieved a dramatic decrease from 0.8 tonnes per resident in 2022. This represents approximately 72.6% reduction compared to 2005 levels. Such rapid decarbonization outstrips virtually every major city globally.
Global Comparison Context
Most major cities still report emissions of 3-8 tonnes per resident. This makes Copenhagen’s performance extraordinary by any measure.
International media estimates indicate a 75-80% emissions reduction by 2024-2025 compared to the 2005 baseline. Official sources confirm these projections. The Danish capital tracks toward the fastest urban decarbonization in modern history.
Timeline Adjustment Reality
The final push to true carbon neutrality has proven more challenging than anticipated. The city has officially postponed its carbon neutral target. Realistic projections now point to 2026-2028.
Success depends on implementing large-scale carbon capture and storage (CCS) technology. This honest acknowledgment reflects climate policy maturation. The shift moves from aspirational target-setting to engineering-based reality.
The Missing Piece: Carbon Capture at Scale
CopenCapture Project – The Technological Gamble
The most critical development in 2025 has been the enhanced partnership between E.ON and ARC. The CopenCapture project launched in March 2025. This initiative represents Copenhagen’s main strategy to close the remaining emissions gap.
Technical Specifications and Current Status
The project aims to capture up to 400,000 tonnes of CO₂ annually. The source is the iconic CopenHill waste-to-energy plant (Amager Bakke). Storage happens through geological sequestration in the North Sea.
Current Technical Status: ARC operates a demonstration unit since 2023. This followed pilot testing in 2021-2022. The current demo facility captures approximately 160 kg CO₂ per hour. This equals roughly 4 tonnes per day.
The captured CO₂ serves primarily for testing solvents and optimizing energy consumption. The facility also integrates waste heat into the district heating system. This represents a crucial bridge between pilot-scale experimentation and industrial deployment.
Industrial Integration Complexity
The technical specifications reveal the challenge’s complexity. CopenHill processes more than 400,000 tonnes of non-recyclable waste annually. The facility produces approximately 2.7 MWh of thermal energy and 0.8 MWh of electricity per tonne of waste.
Integrating carbon capture into this energy-intensive process requires sophisticated heat integration. This represents one of the world’s first attempts at large-scale CCS on a waste-to-energy facility.
Implementation Timeline and Dependencies
Large-scale capture operations are not yet operational at the targeted 400,000 tonnes per year capacity. The timeline extends to 2030 for full implementation.
Success depends on securing adequate financing through Denmark’s national CCS tender process. The project also requires developing offshore storage infrastructure.
Financial Requirements and Municipal Investment
Copenhagen’s 2025 municipal budget allocates 450 million DKK specifically to accelerate CCS implementation. The investment has potential to achieve up to 900,000 tonnes of CO₂ reductions annually city-wide.
An additional 120 million DKK supports sustainable construction initiatives. This funding also supports Climate Plan 2035 development.
ARC explicitly states that the project requires significant state support. This includes CCUS schemes and transport-storage chain development for economic viability.
This technological dependency highlights a crucial lesson about ambitious climate targets: even cities with exceptional renewable energy infrastructure and sustainable transport systems still face significant challenges in achieving complete carbon neutrality without breakthrough industrial solutions.
Building Sector Revolution: Denmark’s New Standards
Construction Emissions Regulations
Copenhagen’s building sector transformation accelerated in 2025. The implementation features stricter life-cycle assessment (LCA) requirements for new construction. Since July 2025, new buildings must meet an average limit of 7.1 kg CO₂e per square meter per year.
This standard is significantly tighter than previous national strategies. It applies to all new building permits in the city.
Municipal Carbon Accounting Integration
The municipality developed a comprehensive CO₂ calculation model for all budget proposals. The focus particularly targets construction and infrastructure projects.
This signals a shift toward incorporating carbon accounting into all public procurement decisions. It also influences technical criteria setting. This approach establishes a precedent for other municipalities.
Building Efficiency and Renovation Programs
The city’s Climate Budget emphasizes continuing efficiency measures across the municipal building portfolio. This builds on targets established in 2010. The goal reduces consumption by 40% in municipal buildings by 2025.
Updates for Climate Plan 2035 are currently being integrated into this framework.
District Heating System Transformation
The decarbonization of Copenhagen’s district heating system remains a central pillar of the climate strategy. The integration of waste heat from CCS operations at CopenHill represents an innovative approach. This maintains system efficiency while reducing emissions.
The district heating system, operated by HOFOR/CTR, serves most of Copenhagen’s buildings. The system transitions toward increased renewable energy sources. This district-wide approach to heating decarbonization has been recognized by C40 Cities as a model. Other cities seeking to rapidly reduce building sector emissions at scale can follow this example.
Green Infrastructure Integration
Copenhagen’s green roof policies have been integrated into local planning requirements for years. The 2024 technical standards for cycling infrastructure also promote increased urban green spaces.
Comprehensive city-wide green roof coverage percentages aren’t published in a single aggregated report. However, the trend toward green infrastructure integration continues across new developments.

Challenges and Future Scenarios
The Final 20%: Why the Last Miles Are the Hardest
Copenhagen’s experience illuminates why the final 20-25% of emissions reduction proves disproportionately difficult:
Technical Complexity: The remaining emissions come from processes that lack mature technological solutions—industrial processes, aviation, shipping, and certain chemical processes. These require breakthrough technologies rather than scaling existing solutions.
Economic Reality: The cost per tonne of CO₂ reduced increases exponentially for final emissions. Early reductions from efficiency and renewable energy provide economic benefits, while final reductions often require significant subsidies.
Infrastructure Dependencies: CCS deployment depends on national-scale infrastructure for CO₂ transport and storage that extends beyond any single city’s control. This creates coordination challenges across multiple levels of government and private sector actors.
Timing Risks: The 2026-2028 timeline for achieving neutrality depends on successful CCS implementation. Delays in financing, permitting, or technical deployment could push the timeline further.
Climate Risks and Adaptation Pressures
Copenhagen faces increasing pressure from sea level rise and extreme weather events, driving continued investment in Cloudburst management and coastal protection. Population growth projections through 2035 add complexity, requiring “growth-with-less-CO₂” strategies that maintain quality of life while reducing per-capita emissions.
The 2024-2025 budget documents acknowledge these demographic pressures, particularly regarding expanded metro and light rail systems to serve growing populations without proportional emissions increases.
Criticism and Trade-offs
The transition to consumption-based emissions accounting in Climate Plan 2035 faces criticism regarding cost-benefit ratios and the practical challenges of measuring and influencing emissions embedded in consumed goods and services. Critics argue for prioritizing projects with demonstrable direct impact over complex accounting methods.
This debate reflects broader questions about the boundaries of municipal climate responsibility and the most effective use of limited public resources.
Lessons for Global Cities
What Worked: The Copenhagen Playbook
Copenhagen’s experience identifies several universally applicable strategies:
Infrastructure Investment Pays: Massive investment in cycling infrastructure achieving 49% modal share for commuting proves that infrastructure creates behavior change. The economic benefits of reduced healthcare costs, decreased congestion, and improved productivity justify initial capital costs.
District Energy Systems Enable Rapid Decarbonization: Centralized district heating serving most buildings allows rapid fuel switching and waste heat integration. Cities with building-by-building heating systems face much higher coordination costs for decarbonization.
Political Continuity Matters: Copenhagen’s climate leadership has been maintained across multiple election cycles and political parties, enabling long-term infrastructure investments and consistent policy signals.
