I was in New Hampshire and so missed the announcement but this is important for those engaged in the SDG indicator process.
The UN Statistical Group IAEG have opened the consultation on the grey indicators here.
An open consultation will take place on the proposed SDG Indicators that currently coded as 'grey', indicating that further discussion on them is still needed. The consultation will be open from Wednesday, 9 December to Tuesday, 15 December to both observers (non-IAEG Member States and representatives of regional commissions and regional and international agencies) and other stakeholders (civil society, academia and private sector) for technical comments.
