Details

Maturity: Established
Promoter: Directorate of Equality (Jafnréttisstofa) / Government of Iceland
Period: 2018–present
Keywords: equal pay, pay certification, gender pay gap, employment law, wage transparency

Context

A Islândia alterou a sua Lei da Igualdade de Género em 2017 (em vigor desde janeiro de 2018), passando a exigir que todos os empregadores com 25 ou mais trabalhadores obtenham a certificação de igualdade salarial segundo a norma ÍST 85 — a primeira certificação de igualdade salarial legalmente obrigatória do mundo. A certificação utiliza uma avaliação de funções que dissocia as tarefas dos seus titulares, é válida por três anos e é monitorizada pela Direção da Igualdade (Jafnréttisstofa).

Results

A disparidade salarial de género não ajustada da Islândia situou-se em 9,3–10,4% em 2023–24, abaixo da média da UE de cerca de 12,7%, e o país lidera o Índice Global de Disparidade de Género do FEM há 15 anos consecutivos. Uma avaliação revista por pares (Social Politics, 2022) concluiu que a norma reduz o enviesamento na classificação de funções, embora a atribuição de resultados especificamente à lei continue limitada.

Transferability / replicability3/3

ÍST 85 was explicitly designed to ISO specifications and has been cited or adapted by Canada, other Nordic countries and the EU Commission as an international model.

Impact on gender equality1/1

Iceland's pay gap (9.3–10.4%) is below the EU average (~12.7%) and the country has led the WEF Global Gender Gap Index for 15 consecutive years; the certification directly targets the pay component.

Effectiveness1/1

All employers with 25+ staff must be certified every three years; the Directorate of Equality maintains a public register and refers non-compliant firms to the Equality Complaints Committee.

Efficiency1/1

Certification leverages an ISO-aligned standard with third-party auditors, adding modest administrative cost while creating a systematic, auditable equal-pay process.

Evaluated outcomes1/1

Peer-reviewed evaluation published in Social Politics (Oxford University Press, 2022) assessed implementation quality and effects on pay classification practices.

Sustainability1/1

The requirement is embedded in the Gender Equality Act and applies continuously; recertification is due every three years with regulatory consequences for non-compliance.

Achievement / evidence1/1

Iceland holds the world's #1 ranking on the WEF Global Gender Gap Index; its pay gap is consistently below EU averages; the certification register is publicly maintained.

Gender-mainstreaming embedding1/1

Gender-equal pay is mandated by law as a structural employer obligation, not a voluntary initiative, embedding pay equity in routine management systems.

Curator validation1/1

Sources include the Icelandic Women's Rights Association equal pay resource, an Oxford Academic peer-reviewed evaluation, and a specialist pay-equity analysis by PayAnalytics.
