After a bit of a Google, I found some reliable sources for possible data sets.
The OECD online library http://www.oecd-ilibrary.org/environment/data/oecd-environment-statistics_env-data-en gives access to environmental data and is certainly promising as a source for data sets. The data here is quite dense, and could be considered comprehensive.
A wealth of data can be found at the UN, https://unstats.un.org/unsd/gender/chapter7/chapter7.html specifically here about women around the world, and how their lived experiences of inequality impact on other aspects of life.
The UN also provides access to data on gender statistics, https://genderstats.un.org/#/home which could prove valuable to this project and the explorations within it.
