Climate Change Adaptation

Climate change adaptation is the second environmental objective of the EU Taxonomy and addresses the need for economic activities to build resilience against the physical impacts of a changing climate. Unlike mitigation, which focuses on reducing emissions, adaptation is about preparing for the consequences that are already locked in due to historical emissions. This includes acute hazards such as heatwaves, floods, and storms, as well as chronic hazards like rising sea levels, shifting precipitation patterns, and increasing average temperatures.

The Taxonomy requires that an activity making a substantial contribution to adaptation must either implement physical and non-physical solutions that substantially reduce the most important physical climate risks to that activity, or provide adaptation solutions that substantially contribute to reducing physical climate risk for other economic activities, people, nature, or assets. A critical prerequisite is the performance of a robust Climate Risk and Vulnerability Assessment (CRVA) compliant with the criteria set out in Appendix A of the Climate Delegated Act. This assessment must consider a range of climate scenarios, including a scenario consistent with at least a 2 degrees Celsius warming pathway, and must cover a timeframe appropriate to the expected lifetime of the activity.

The adaptation objective covers approximately 68 economic activities, many of which overlap with those listed under mitigation. For the built environment, adaptation is particularly significant. Buildings must undergo a physical climate risk assessment and implement adaptation measures proportionate to the identified risks. This often requires high-resolution climate data, including microclimate analysis for urban heat islands, flood risk mapping, and wind pattern assessment. Computational Fluid Dynamics (CFD) simulation has emerged as one of the most rigorous methods for providing the building-level evidence that auditors expect under the Taxonomy framework.

The Do No Significant Harm (DNSH) criteria for adaptation require that the activity does not adversely affect adaptation efforts by other parties and does not increase the risk of an adverse impact of the current and expected future climate on people, nature, or assets. Companies and financial institutions must demonstrate that their adaptation measures are monitored, updated when necessary, and aligned with national and sectoral adaptation strategies where available.
