Women in G20 countries will have to wait 75 years to earn as much as men, according to an Oxfam report published today.

The report also found that if women's paid employment rates were the same as men the eurozone's GDP would increase by 13%.

A radical change of attitude among society and government is now called for in order to address this issue, according to Oxfam Ireland CEO Jim Clarken.

The EU is represented at the G20 by the President of the European Council and by the European Central Bank.

The report on gender equality was published today in advance of a G20 Business Summit in Australia this week.

It shows that in the G20 countries women were paid less than men; were over-represented in part-time labour, and were discriminated against in the household, markets and institutions.

The report also highlighted the interaction between women's paid and unpaid workloads.

Women across G20 countries work an average of two-five hours more unpaid work than men per day, which the report said effectively behaves as an economic subsidy.

The monetary value of unpaid care work is estimated at anything from 10% to over 50% of GDP.
