Urgent global action is required to address unsustainable material resource use. This report explores the possibility of, and analyses the implications associated with, developing an international agreement on the management of natural resources.

Why an international agreement?

An international agreement could support

• incentivizing action on a global level
• generate awareness to tackle the issue of resource management
• solve the issue of uncoordinated actions at various regional and governance levels.

The report also looks at the extent to which Free Trade Agreements (FTAs), many of them including provisions relevant to developing circular solutions, cover natural resource management and could be leveraged to enhance resource efficiency.

France's Law Against Food Waste has become an international model for sustainable food policy. The law is often described as combining economic efficiency with environmental protection and social equity. However, stakeholder narratives cast doubt on whether this French CE law really contributes to social justice in the long run. This discourse analysis shows that:

• the ban on food waste institutionalised a narrative about food waste that prioritises profit over social equity
• the traditionally dominant solidarity narrative about food waste has been pushed back by the emerging CE discourse
• As a consequence of this shift, activities enacted in the name of the CE may counteract social equity goals (for instance by establishing competition with charities).

Policies are focusing on halving food waste to help conserve increasingly strained food resources. However, expanding their scope of action to include dietary changes and complement targets with resource footprints has greater potential to save resources while avoiding trade-offs.

This paper shows that in Germany:

• Healthy, plant-based diets are more effective at reducing land and biomass use than halving food waste
• A combination of more plant-based food consumption and food waste reduction in distribution and consumption is most effective at saving resources
• Focusing exclusively on food waste reduction as a policy target can be detrimental to the overarching goal of saving resources because it deflects attention away from more effective alternatives.

The circular economy (CE) is gaining momentum in cities. To ensure a sustainable CE, it is crucial to measure the environmental performance of CE strategies. However, environmental assessments overlook several strategies that are a key feature of urban CE practice. These include reuse and repair, sustainable built infrastructure and urban land use, green public procurement, smart information and access technology.

To provide insights into the environmental performance and potential of these strategies, industrial ecologists and municipalities should:

• collaborate with urban systems experts
• quantify the environmental impacts of entire urban systems
• combine environmental assessments with social and economic feasibility ones.

This literature review identified and categorised circular economy (CE) practices within all stages of the food and feed production chain in Europe to provide an overview of current and envisaged practices. There are four macro areas:

1. primary production of food and feed
2. reducing industrial/manufacturing/processing waste
3. reducing food and feed waste in wholesale, food retail, catering and households and
4. reducing food and feed packaging waste.

It is recommended that future primary research in novel food and feed in the CE focuses on areas other than insect farming, and that there are further investigations into the potential risks associated with importation into the EU of livestock/goods that may have been subject to different restrictions/legislation.
