Last week in Bangkok, 28 statistics experts from around the world discussed...how the new Sustainable Development Goals can be measured...Even before Bangkok, several drafts of proposed indicators had been shared, so that going into the meeting there were already over 200 proposed indicators with varying levels of agreement...After several pleas from observer countries and civil society for a more open process to decide on the final framework, expert group co-chairs announced that an online portal for giving feedback on the green indicators...Opening up the platform represents a positive move toward inclusiveness and a realization that measuring (and more importantly, implementing) these SDGs is going to require new types of collaboration. Many of the issues debated simply cannot be determined in a U.N. meeting room, whether it is in Bangkok or New York. The world needs a chance to “try on” these indicators, provide feedback as to how they are working, and use that information to keep refining them over time.
