EU Climate Resilience Tools and Enterprise Data: Viewer, Navigator, and Where the Grid Stops

The EU Framework for Climate Resilience, presented on 27 October 2026, is not only a draft law. COM(2026) 720 launched a public digital layer so that authorities, businesses, and residents can see hazards and find tools without commissioning a model first.

That layer is worth using. It is also easy to over-read. A map of a projected hazard — the Commission’s own example is health-threatening heat and water shortage under 2°C around 2050 — answers a different question from the flood depth at one warehouse, or from the residual risk after a specific measure. This guide separates the two. Each tool has a short note on the question it answers and the question it does not: European Climate Viewer, EEA Navigator, Mission Solutions Explorer, and EIB ClimateSET, which is not released.

The legal context — the 1.5°C / 2°C / 3°C reference trajectory, named risk owners, and the 2028–2030 timetable — is in the policy analysis. How we work with organisations on permits and tenders is on the readiness page.

The public stack, as launched

Article 9 of the proposed European Climate Resilience Law would require the Commission to keep an online platform on climate resilience knowledge, including access to the European Climate Viewer. The Communication says that platform will, over time, upgrade and replace Climate-ADAPT, while keeping what is already useful there. The pieces that exist now are these.

European Climate Viewer

The European Climate Viewer is developed by the European Centre for Medium-Range Weather Forecasts, which runs the Copernicus Climate Change Service, in partnership with the European Commission. Its about page says the development is carried out by AtkinsRéalis and Lobelia Earth. Its job, in the Commission’s words, is to convert the reference global warming trajectory into local, decision-relevant information on projected climate hazards.

A user picks a hazard, a warming level on the reference trajectory, a sector, and a location. The Commission’s example is health-threatening heat and water shortage under a 2°C world around 2050. The about page says exposure and vulnerability data will be added over time. The Commission also says the viewer will later cover the effect of resilience measures, using Destination Earth sector models and the JRC Risk Data Hub among other inputs.

Today it is a hazard viewer tied to a shared warming path. That is already more useful than a slide that says “RCP 8.5” with no map. It is not a floor-level flood depth, an indoor heat metric, or a risk model of your asset. The longer note is here.

Navigator of Climate Resilience Tools

The European Environment Agency launched the Navigator of Climate Resilience Tools on Climate-ADAPT the same day. The EEA’s announcement describes a curated catalogue of interactive tools across the adaptation sequence: assessing risk, planning, implementing, and monitoring. Tools are reviewed by EEA experts with the Eionet network of member and cooperating countries. Users can filter by sector, climate hazard, region, and adaptation need.

The Navigator answers “which assessed tool covers this hazard and sector?“. It does not run the tool for you, and an EEA review is not a judgement that the tool is fit for a lender or a permit. The longer note is here.

Mission Solutions Explorer

The Solutions Explorer of the EU Mission on Adaptation to Climate Change collects measures that have been implemented, how they were resourced, what benefits were reported, and how a region or city might replicate them. You can filter by country, climate hazard, and theme, including adaptation funding and financing. The Commission says it will open the collection to a wider set of contributors.

This is a library of practice, strongest for municipalities and for nature-based or neighbourhood-scale measures. How another place paid for a measure is not a transferable cost for your site. The longer note is here.

Financial and insurance tools still arriving

COM(2026) 720 names further tools that are not the same thing as the Viewer:

EIB ClimateSET (Climate Hazard Screening and Exploring Tool), described as forthcoming and open access. The Communication says it draws on “CS3” data, which in context is Copernicus C3S. The Viewer’s about page says ECMWF developed ClimateSET with the EIB, on the same hazard data and modelling framework as the Viewer. There is no public address yet. It is a coarse screen for assets and investments, next to adaptation modules in the EIB Group Green Checker and the taxonomy adaptation criteria — not a vulnerability curve or a set of insurance terms. The longer note is here.
EIOPA PROTECT, for property owners, on climate risk and prevention, and a planned Observatory for Catastrophe Risk Insurability.

Use them when they are actually available. A press mention is not a dataset.

An Earth System Tipping Point Observatory is also announced as an intention, to sit beside the Viewer. It is not a tool you can open today.

What this stack is good for

Question	Start here	Do not expect
How does the EU reference trajectory look for this region?	European Climate Viewer	A floor-level flood depth or indoor heat metric
Which assessed tool covers this hazard and sector?	EEA Navigator	A judgement that the tool is fit for a lender or a permit
What have other cities already tried, and how was it paid for?	Mission Solutions Explorer	A transferable cost for your site
Is this asset inside a coarse climate-hazard screen for finance?	EIB ClimateSET, when released	Your vulnerability curve or insurance terms
Which open dataset exists beyond the EU catalogues?	Climate Risk Intel Tool Hub	An integration into your data lake

The Commission’s own motive for the stack is stated plainly in section 3.1 of the Communication: many policymakers, businesses, and individuals still lack usable, trustworthy online information. Publishing the Viewer and the Navigator is a direct response. The European Environment Agency is also given a standing role, in the proposed law, as a centre of excellence for resilience knowledge, indicators, and the platform.

For discovery beyond that EU catalogue, Climate Risk Intel is our open Tool Hub: a curated directory of open climate and nature risk tools and datasets from institutions including NASA, ESA, Copernicus, and the World Bank. It is complementary to the Navigator, not a rival official catalogue. The Navigator is the EEA’s reviewed list for the EU adaptation workflow. The Tool Hub is a wider index for teams who also need global public data and research datasets.

Where a regional hazard map stops

Public climate data is built for a different spatial question than a single building. ERA5, the Copernicus reanalysis many downstream products rely on, is on the order of a 31 km grid. Many global climate models are coarser still. Even careful statistical downscaling often stops near 10 km. We set out why that is a market and a justice problem, not only a technical one, in Climate Risk Data Quality Is a Market Problem.

The Viewer shows hazards under a common warming path. It does not publish a grid size, and we are not treating the ERA5 spacing above as the Viewer’s resolution. Ease of viewing does not create local drainage, flood defences, building fabric, or occupancy. The Communication says the Viewer will grow toward vulnerability and toward the effect of measures. Until it does, and even after it does at regional scale, an asset decision still needs its own method note.

Three limits show up as soon as money or a permit is involved.

Resolution choice changes the number. Miller, Ormaza-Zulueta, Koppa, and Dancer (2025) held the climate model and scenario fixed and varied only the statistical downscaling product. Projected end-of-century output losses differed by as much as about 9.8% of gross regional product in some locations. No single product was the high outlier everywhere. The practical checklist is in Preparing Your Own Climate Data. If you put Viewer output and a downscaled layer in the same slide, say which is which.

Vendors do not quietly agree with each other or with a public map. Seven vendors in the Investor Leadership Network study did not agree on flood exposure along a road outside Paris beyond the one obvious riverside site. We summarised that, and the GARP 13-vendor benchmark, in Why Climate Risk Vendors Disagree. A Navigator entry for a commercial tool is a discovery result. It is not inter-comparison.

Residual risk is a decision, not a layer. The proposed law asks strategic plans to say what loss remains acceptable after measures, and how maladaptation is avoided. A hazard map cannot state that. It can inform it. Cost and benefit of specific measures, for organisations that need the calculation in-house, is what we implement with CLIMADA on the climate risk software modules: data lake, ingestion, map layers for river and pluvial flood, building heat, shade and green cover, a downscaling pipeline, and cost-benefit analysis. You deploy the modules the decision needs. You do not need all of them to use the European Climate Viewer.

Open tabular climate data, once you are past the web map, is an engineering problem of its own. Open climate risk datalakes with DuckDB covers one way teams keep Copernicus-scale and downscaled fields queryable without a new warehouse project.

A sequence that does not skip the public baseline

For a site, a municipal service, or a bid, the order that matches the framework is:

Screen on the reference trajectory in the European Climate Viewer for the hazards the Viewer actually shows for that place. Keep a worse case next to the baseline if the decision is hard to reverse. The proposal itself asks for stress tests, not only the reference path.
Find candidate tools in the EEA Navigator, filtered by hazard, sector, and whether you are assessing, planning, or monitoring. Read the method note of anything you might rely on. “Reviewed for the catalogue” and “fit for this decision” are different sentences.
Look for a worked example in the Mission Solutions Explorer if the measure is civic, nature-based, or neighbourhood-scale. Treat reported benefits and resourcing notes as context, not as your business case or a cost for your site.
Decide whether the question is still regional. Portfolio screening and a first conversation with a public authority can often stop at steps 1–3, with the sources written down.
If the question is an asset, a permit, or a euro amount, separate download, downscaling or bias correction, and aggregation to the decision unit. Document native resolution and the aggregator. Prefer more than one model lineage where the impact is non-linear. Benchmark extremes against observations where you can. That is the same hygiene as in the downscaling guide, applied to a file that may be read by a planner or a buyer.
Only then attach vulnerability and, if you are choosing measures, a cost-benefit comparison. Industry-average damage curves are a weak description of a high-value or unusual asset. The climate risk assessment approach is to build custom vulnerability with the people who operate the asset, and to let finance own the cost-benefit, not to replace them with a score.

Cross-sector groups will still need a language for “how resilient is this organisation” that is not a municipal plan. The Adaptation Exchange works on that: a resilience standard, a business case, and a stack of measures. The EU tools give those conversations a public map. They do not write the standard.

What not to claim in a tender or an EIA

Do not cite the European Climate Viewer as evidence of asset-level vulnerability or of residual risk after a measure.
Do not cite the Navigator as an endorsement of a vendor’s financial loss model.
Do not treat one downscaled grid as the uncertainty range. Say which products you compared, or say that you did not compare them.
Do not describe the framework tools as Climate+Tech products. They are Commission, ECMWF, EEA, and Mission tools. Our Tool Hub and software modules are separate, and they are only relevant when the public baseline is no longer the question you are answering.

If you need that last step scoped — which sites, which file, which module — that conversation starts on the readiness page.
