Historically, human uses of land have transformed and fragmented ecosystems, degraded biodiversity, disrupted carbon and nitrogen cycles, and added prodigious quantities of greenhouse gases (GHGs) to the atmosphere. However, in contrast to fossil-fuel carbon dioxide (CO2) emissions, trends and drivers of GHG emissions from land management and land-use change (together referred to as ‘land-use emissions’) have not been as comprehensively and systematically assessed. Even where land-use change emissions are negligible or negative, total per capita CO2-equivalent land-use emissions remain near 0.5 tonnes per capita, suggesting the current frontier of mitigation efforts. Our results are consistent with existing knowledge—for example, on the role of population and economic growth and dietary choice—but provide additional insight into regional and sectoral trends.

Export superstars are important for export growth and diversification and are typically born large. Firm-level data on manufacturing trade from 32 developing countries show that the top five exporters account for on average nearly one-third of exports, 47 percent of export growth, and a third of the growth due to export diversification over a five-year period. Within countries and industries, export growth is positively correlated with the share of exports in the top five firms. Most of the top five exporters were already large five (or eight) years ago or are new firms; it is rare for these export superstars to emerge from the bottom half of the distribution of firm sizes. For countries where detailed data exist, superstars

Most research on private governance examines the design and negotiation of particular initiatives or their operation and effectiveness once established, with relatively little work on why firms join in the first place. We contribute to this literature by exploring firms’ willingness to participate in two recent, high-profile private initiatives established in the aftermath of the Rana Plaza disaster in the Bangladesh ready-made garment (RMG) sector: the Accord on Building and Fire Safety and the Alliance for Worker Safety in Bangladesh. We are able to positively attribute only a minority of US RMG imports from Bangladesh to Accord and Alliance signatories. Firms headquartered in the USA were much less likely to sign onto remediation plans, especially the Accord.
