Bizkaia

Public company that operates the metro of the metropolitan area of Bilbao. It recovers the braking energy of its trains (up to 8%, about 2,200 t CO2/year avoided), calculates and verifies its carbon footprint (ISO 14064 since 2012), is registered in EMAS (ES-EU-000031) and publishes sustainability memories since 2002.

Detail of score

The data are calculated with improvements, evidence and connections currently published in EkoPulse.

Model used for this calculation: Impact 2.0 · Reliability 1.3.

Impact: 39 points

Cumulative score

Provisional model: each improvement is assessed by its reach for this profile type, from symbolic to transformative. The same work counts once. Contributions are combined with diminishing returns, and relevant relationships are added. Evidence adds 0 direct Impact points. This does not measure tonnes or net impact.

The highest reach levels require human confirmation; until then they receive a conservative rating. New or edited improvements use a provisional level until their current text is reviewed.

4 sustainable improvements (weighed by their reach)+39.1
0 improvements with evidence+0
0 ecosystem connections+0
Profile’s own base39
Ecosystem influence+0
Total impact39

The own base combines practices and direct relationships. Direct relationships and ecosystem influence together add at most 4 points. Ecosystem influence can extend up to 3 steps away and depends on relationship trust and nearby profiles’ data. A disputed relationship transmits no influence through the graph, although it can retain direct credit if its category is eligible. Relationships do not generate negative points.

The advisory thresholds are 25 profiles with improvements, 5 with at least 25 points and at least one reaching 95 points. The current figures are 112, 34 and 72, respectively. Reaching these thresholds does not activate comparison: it requires a model decision.

Reliability: D

7 / 100

The model first places the information in a band according to its supporting evidence. It then calculates the score within that band.

Contributions are shown rounded; the total uses the original calculation before final rounding. Ecosystem support is already included and is not added again. Under the current model, the maximum attainable is B+ (84/100).

Evolution of the score

The history shows saved snapshots, not a live calculation. Each snapshot retains the model used to calculate it; a model change does not by itself mean the profile’s activity changed.

View snapshots and methodology

Two different scales, the same dates. Only recorded snapshots are shown; earlier scores are not reconstructed.

EkoPulse scores are recalculated as the available information changes and the evaluation model evolves. Methodological improvements may result in changes in the score that do not necessarily reflect an equivalent change in profile performance.

Energy

Energy
Recovery of braking power from trains and return to the electricity grid Added by EkoPulseEnergy efficiency project whereby Metro Bilbao trains recover some of the electrical energy on the brake - previously lost in heat form - and return it to the network, deducting it from the energy bill: up to 8% of the energy used is recovered and the emission of about 2,200 tons of CO2 per year is avoided; the energy consumed is renewable (green energy 100%).

Community and persons

Community and persons
Publication of sustainability reports and memories since 2002 (memory 2024 available) Added by EkoPulseMetro Bilbao published its first environmental report in 2002 and since then publishes sustainability reports and memoirs (with the requirements of GRI) who are accountable to clientele, staff and other interest groups for their economic, social and environmental actions; 2024 is available for download.

EMAS Register (ES-EU-000031) and Environmental Declaration validated by AENOR Added by EkoPulseMetro Bilbao is registered in the Community environmental management and audit system EMAS with registration number ES-EU-000031 (granted by resolution of the Vice Councillor for Environment of the Basque Government) and publishes its Environmental Declaration, validated by AENOR, with the evolution of its environmental performance and impact minimisation results.
