This paper explores both the role that local content measures can play in advancing sustainable development, and the impact that trade and investment treaties concluded over the past 20 years have had and will continue to have on the ability of governments to employ those tools. Certain local content measures had been restricted under the WTO due to wide agreement by negotiating parties that their costs outweigh their benefits. But the WTO also left a number of local content measures in governments’ policy toolboxes. As is discussed in this paper, however, that is changing, with the range of permissible actions for many countries being significantly smaller than it was even a decade ago. This narrowed policy space, in turn, can limit the steps governments can take to make progress on the universally adopted Sustainable Development Goals.
