Chamber: congestion cost EUR 770m, 3.4% of GDP

TL;DR

In its proposals for the 2026–2031 legislature (“LEAD”, 14 May 2026), the Malta Chamber of Commerce, Enterprise and Industry wrote: “In 2025, traffic congestion imposed an estimated cost of €770 million on the Maltese economy, equivalent to 3.4% of GDP.” We traced the figure to its source and recomputed the share of GDP.

1. The €770 million is the government’s own figure, cited correctly. The Chamber’s footnote points to the National Transport Master Plan 2030 (January 2026), which says the cost of congestion is projected to reach €917 million a year by 2030, “up from €770 million in 2025”. The European Commission’s 2026 Country Report repeats the same figures from the same plan.
2. But no published method stands behind the 2025 figure. The plan gives no calculation for 2025. Its appraisal annex models 2030 and 2060 only, and two of its tables (lost time and idle fuel) carry identical numbers. We could not reproduce or test the €770 million.
3. “3.4% of GDP” does not reproduce. €770 million is 3.1% of Malta’s 2025 GDP at current prices (€24.7 billion, Eurostat), the like-for-like comparison. 3.4% would need GDP of €22.6 billion; 2024 nominal GDP gives 3.3%, and the Chamber’s own real GDP figure gives 3.8%.
4. Verdict: not substantiated (moderate confidence). A cost of this order may well be real, but the central figure has no published derivation, and the GDP share is stated higher than the data give. This is not a finding that the Chamber misreported its source: it reported it accurately.

IN THIS REPORT

1 The claim and what we could verify

The sentence is on the third page of “LEAD – The Malta Chamber Proposals for the 2026–2031 Legislature” [1], published on the Chamber’s website with a press release on 14 May 2026 and read in full on 5 October 2026. Its footnote 2 cites “Transport Master Plan 2030 (Page 124)”. Lovin Malta reported the proposals the same day in its own words [2]. The cited plan is the National Transport Master Plan 2030 (document title “National Transport Strategy 2025 14 JAN26 (REV)”) [3]; the government site refuses automated access, so we read it from an Internet Archive copy of 21 March 2026.

2 Method

Question. Where does the €770 million come from, can it be tested, and is it 3.4% of GDP?

Evidence. We read the Chamber’s document and the plan it cites, searched the plan for the derivation of the 2025 figure, and recorded the plan’s figures in data/cc-115/congestion_estimates.csv. We downloaded Malta’s GDP from Eurostat (nama_10_gdp, updated 2 October 2026) and computed the share on each basis (tools/cc-115-report/calc.py; outputs in data/cc-115/checks.csv). A cost in euros of 2025 is compared with GDP in euros of 2025, i.e. at current prices; the other ratios are shown because the Chamber’s document uses real GDP elsewhere (its €11.34 billion for 2015 matches Eurostat’s chain-linked series at 2020 prices).

Grades. Official statistics and the government plan are grade C; the plan’s 2025 figure is an assertion without a published method (D) until its derivation is published. Verdicts follow the five-point scale in Appendix A.

3 What the data show

Malta’s GDP in 2025 was €24,664 million at current prices; €770 million is 3.12% of it. Against 2024 GDP (€23,079 million) it is 3.34%, which would round to 3.3%. Against real GDP in 2020 prices it is 3.85%, and against the Chamber’s own real GDP figure (€20.40 billion) 3.77%. None of the published series gives 3.4%; that would need GDP of about €22.6 billion.

In the plan, the only derivation we found is in the appraisal annex (pp. 218–221), which values lost time with HEATCO unit values for 2030 (11.04 million hours a year, €248 million) and 2060. It does not cover 2025, and the plan does not show how the €770 million or the €917 million is assembled.

4 Where the evidence points different ways

5 Testing the claim

6 Verdict and requests for evidence

Why. Our scale rates a claim Not substantiated when its central figure has no evidence that can be checked. The €770 million comes from an official plan but without a published calculation, and the 3.4% does not match Malta’s GDP on the like-for-like basis (3.1%). Confidence is moderate because the plan’s authors may hold a calculation we have not seen.

What this verdict does not say. It does not say congestion is cheap, that the figure is wrong, or that the Chamber misreported its source: the Chamber quoted the government’s plan and gave the page. The missing piece is the plan’s method. A fuller sentence would read: “The government’s transport plan puts the cost of congestion at about €770 million in 2025, roughly 3% of GDP, without publishing how it was estimated.”

Evidence we are asking for

• From the Ministry for Transport and Transport Malta: the calculation behind €770 million (2025) and €917 million (2030): hours lost, values of time, operating costs and base year.
• From the Malta Chamber: the GDP figure used for “3.4% of GDP”.

7 Limitations

• We read the government’s plan from an Internet Archive copy; the live file refuses automated access.
• We searched the plan’s text for the derivation; a calculation could exist in an annex or model report not published with it.
• The Cremona estimate is known to us only from the claim record’s summary of a news report (second-hand, ◆).
• GDP figures are revised; the share would differ slightly with an earlier vintage.

Appendix A: series standards and verdict scale

Every investigation in this series follows the same rules so that verdicts are comparable and challengeable.

Confidence

High: multiple independent lines of evidence agree. Moderate: evidence is relevant but incomplete or indirect. Low: evidence is thin, second-hand or conflicting.

Evidence grades

A experiment · B observational study with a control or gradient · C review, guidance or official statistics · D assertion or anecdote. ◆ marks a source known only second-hand.

Standards

• Quote the speaker, not the headline, with outlet and date, and link the original where possible.
• Separate the claim from the evidence offered for it, and say who made which statement.
• Grade the evidence and show differing views side by side where the evidence is unsettled.
• State what we could not access or verify, and what would change the verdict either way.
• Ask for the missing evidence in specific, answerable requests.
• Offer a right of reply where a check finds a claim Not substantiated, Misleading or Contradicted (or a pledge Not measurable, Off track or Missed), before wider circulation, and append responses.
• Correct errors openly with a version number and change log.
• Whistle-blow only on evidence: a verdict of Misleading or Contradicted requires documents or data that can be shown, not inference.
• Check every side. Government, opposition, NGOs and developers are held to the same standard.
