Market Size- 40% weighting
€19B EU retrofit market (2024) growing at 10% CAGR, driven by regulatory deadlines and €5.4B LIFE Programme funding
Only 15% of EU coastal defences currently integrate NbS despite 70% cost-effectiveness advantage over grey infrastructure
EU climate adaptation market is €29B (2024), with retrofits accounting for 65% of spending
Customer Pain- 40% weighting
Coastal authorities face €50B in climate-related liability claims by 2030 if retrofits lag
2027 EU mandate threatens 4% revenue fines for owners lacking resilience audits
23% of EU coastal infrastructure is at high risk of flooding by 2030, with repair costs exceeding €12B annually
40% of EU road networks require urgent retrofits to address climate damage 
Room to Play- 20% weighting
Despite EU mandates (e.g., Nature Restoration Law), fewer than 15% of infrastructure projects use hybrid engineered-NbS retrofits
Climate tech startups secured €7.7B in equity in H1 2024, but most are pre-Series B. No unicorns dominate the retrofit segment

Problems Addressed
23% of EU coastal infrastructure is at high risk of flooding by 2030, with repair costs exceeding €12B annually
40% of EU road networks require urgent retrofits to address flooding and heatwave damage
Regulatory pressure under the EU Climate Law (55% emissions cuts by 2030) mandates retrofits, but 60% lack funding for large-scale upgrades
Market Opportunity
€18.7B EU retrofit market (2024) growing at 10.5% CAGR, driven by regulatory deadlines and €5.4B LIFE Programme funding.
EU climate adaptation market is €28.7B (2024)
10.5% CAGR (2024–2030), driven by EU mandates like the Nature Restoration Law (30% ecosystem restoration by 2030) and €1.8T Recovery and Resilience Facility.
2027 EU Climate Adaptation Strategy requires all public infrastructure to undergo resilience audits
Ramboll’s Advantage
Proven expertise in hybrid seawall designs (e.g., Dutch Delta Works) and circular economy retrofits (22% material savings in Stockholm Bypass)
Opportunity to lead EU-funded projects like LIFE ACT (€86M for coastal resilience) by integrating AI-driven LCA tools with green bond financing
Existing Portfolio
EcoImpact Tool - Assess 850+ material profiles to enable CSRD-compliant reporting, critical for green bond eligibility.
