Center for Ethics and Sustainable Development (CESD) successfully hosted the first edition of the UNEP-DHI Eco Challenge 2018 in partnership with UNILAG Center for Housing and Sustainable Development in Lagos Nigeria. The 3-day Eco Challenge started on the 18th and ended on the 20th of October, 2018.
