Food policies and climate: a literature review

25 February 2019 - Climate Report - By : Claudine FOUCHEROT / Valentin BELLASSEN / Lucile ROGISSART

Food consumption is responsible for around 28% of total greenhouse gases (GHG) emissions (see I4CE study on the issue)

Which dietary practices have the largest potential for reducing food-related GHG emissions? Is it possible to reduce food-related emissions while also targeting public health and environmental goals such as the preservation of soils or water quality? Which public policies could be implemented to push consumers towards less GHG intensive diets?

In the present study, I4CE summarizes the answers academic literature can bring to these questions.

It appears that reducing the intake of animal products has a major mitigation potential, as these products are responsible for almost two thirds of total food-related emissions. Besides, dividing by two the current levels of food waste could enable to reduce food-related emissions by 5%. The origin or the seasonality of products have a limited impact comparatively to total food GHG emissions.

    2023’s resolutions for a reform of development finance

    2022 ended up on a consensus that the global financial architecture is no longer “fit for purpose”. In other words, the financial ecosystem created post-war to support international development – at the centre of which are the IMF and the World Bank who were joined later by other international public financial institutions – wasn’t designed to address the multiplicity of challenges the world is facing today, foremost among which climate change. Time is running, and the good news is that 2023 is set up to be a busy year with key events setting the milestones for a reform of the international financial architecture, including a Paris Summit in June. The year will close at COP 28, where we will officially take stock of current achievements.

    Here’s to an impactful new year for financial reform

    2023 will be busy with many events organised to address different parts of the financial architecture reform, including a Paris Summit in June. Alice Pauthier from [i4ce] tells you more about this agenda and identifies two conditions for a successful reform process. First, it has to be led by countries’ financing needs… wheras we are still lacking a granular analysis of countries’ investment needs for a sustainable development. Second, it has to be guided by the objective of maximising the impact of public finance. What we should count is the impact of public finance on the transition and not only volumes.

    The limitations of voluntary climate commitments from private financial actors

    Private finance will not fund the transition without a stronger commitment from public authorities.
    For several years, and particularly since COP 26, considerable time and attention has been dedicated to the subject of voluntary commitments from private financial actors. These commitments, made within the framework of international initiatives, should in principle enable private finance to be mobilized for the transition to a carbon neutral economy.
