SDG 12

Worldwide material consumption has expanded rapidly, as has material footprint per capita, seriously jeopardizing the achievement of Sustainable Development Goal 12 and the Goals more broadly. Urgent action is needed to ensure that current material needs do not lead to the overextraction of resources or to the degradation of environmental resources, and should include policies that improve resource efficiency, reduce waste and mainstream sustainability practices across all sectors of the economy.

The Regional Decarbonization Framework (RDF) anchors the San Diego region in emerging best practices from across the nation and globally. It charts science–based, feasible pathways toward expeditious deep decarbonization, proposing a paradigm shift in our local economy. The scale and pace of this effort will require partnerships between public and private sectors, particularly, business, labor and environmental communities. The input from these numerous stakeholders not only shaped the RDF itself, but initiated many of those collaborative efforts needed for…

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.

The Zero Carbon Action Plan (ZCAP) will serve as a roadmap for the U.S. based on the latest modeling, research and understanding of decarbonizing six key sectors (power, transport, industry, buildings, food and land use, and materials) supported by technical pathways to zero carbon by 2050, as well as supporting policy recommendations. The ZCAP was designed by a cohort of nearly 100 researchers and 19 Chairs who make up the Zero Carbon Consortium, who are experts in their fields of climate change policy; clean energy pathways modeling; industrial policy high-employment green economies; legislative and regulatory policy; electricity (power) generation; transportation; industry; buildings; sustainable land-use; and sustainable materials management.

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.

This paper examines the effect of stringent environmental regulations on firms’ environmental practices, economic performance, and environmental innovation. Reducing COD levels by 10% relative to 2005 levels is an aim of the Chinese 11th Five-Year Plan. We find that more stringent environmental regulations faced by firms are positively associated with a greater probability of reducing COD emissions; also, there exists an evident heterogeneous effect across industries with different pollution intensities. Stricter environmental regulations also account for the sharp decline in firms’ profits, capital, and labor. We find that firms rely more on recycling and abatement investment than on innovations when meeting environmental requirements.
