Reducing animal‐based food production would not only reduce agricultural greenhouse gas emissions but also free land that could sequester carbon. We examine the efficiency of a subsidy to cattle farmers for setting aside land for natural ecosystem regeneration. We develop a partial equilibrium model of the cattle sector that integrates land use, gr...
The potential regressivity of an emission tax is a major obstacle to the implementation of this otherwise cost-effective instrument. Rebates may help overcome this difficulty. Their distributional consequences depend on their design and the distribution of agents’ initial emissions and abatement costs. We develop a stylized analytical framework to...
This paper explores the effects of a public policy that reduces by 50% the use of mineral nitrogen in European agriculture. Our results show that, for the European Union, halving mineral fertilizer use leads to: a decrease in agricultural production, a substantial increase in nitrogen use efficiency, lower use of organic fertilizer and a loss of ag...
There is a lack of clear empirical evidence towards the lower carbon footprint of organic food products, in particular in the dairy sector. Until now, small sample sizes, lack of properly defined counterfactual and the omission of land-use related emissions have hindered comparisons of organic and conventional products. Here we bridge these gaps by...
Mineral nitrogen (N) application in agriculture has significantly increased food production over the past century. However, the intensive use of N fertilizers also impacts negatively the environment, notably through greenhouse gas emissions and biodiversity loss and remains a major challenge for policymakers. In this paper, we explore the effects o...
This paper assesses the drivers of greenhouse gas emissions and economic performances for a sample of dairy farms Protected Designation of Origin dairy farms in France. Investigating caeteris paribus drivers of performance, we conclude that synergies are rare. Investing in farming equipment, optimizing fuel use or suppressing manure composting can...
This study focuses on the links between food production and greenhouse gas emissions in the European Union. The analysis relies on two sets of simulations of AROPAj, a supply-side model of EU agriculture: (i) a carbon price affecting agricultural GHG emissions (from 0 to 200 EUR/tCO2eq), and (ii) a lower limit on the net quantity of food calories p...
The aim of this study is to analyze the behavior of French consumers with respect to food products under various quality labels (organic, label rouge, and geographical indications). In particular, we investigate if consumers who purchase once a product under a given label tend to purchase a large fraction of this product (and other products) under...
We assess the potential for increasing the net amount of food calories produced by French agriculture and the possible implications in terms of greenhouse gas emissions and agricultural area allocation. This analysis is based on an agricultural supply model for the European Union mainly with regard to arable crops, meadows, fodder crops, and the ma...
Cette étude traite de la régulation des gaz à effet de serre d'origine agricole et animale. On évalue les impacts des mesures de taxation des facteurs d'émissions de gaz à effet de serre et de prime au carbone stocké. Une taxation directe des émissions responsables du changement climatique permettrait de réduire son coût social de façon efficace. M...
La prise en compte des interactions à de nombreux titres entre activités de production agricole et animale conduisent à proposer un modèle agro-économique d’intégration capable d’en restituer la complexité. Les émissions de gaz à effet de serre autres que le dioxyde de carbone, la variabilité des aliments du bétail produits sur la ferme ou dans l’i...
The French dairy sectordlike the rest of the economydhas to address the challenge of mitigatinggreenhouse gas (GHG) emissions to curb climate change. Deciding the economically optimal mitigationlevel and mix of abatement strategies requires knowledge on the cost of reducing GHG emissions.Agricultural bio-economic models can help identify which prod...
Environmental policies often include exemptions for some firms, e.g. the small emitters. This paper explores the implications of such exemptions in the case of an emission tax, and in the presence of monitoring, reporting, and verification (MRV) costs. We develop an analytical framework capturing the trade-off between the cost-effectiveness of a br...
This study aims to characterise steady-state land allocations between a multiple-stand forest and agriculture, when the forest is subject to a storm risk. The landowner is supposed to have recursive preferences, which permits to distinguish between intertemporal preferences and risk preferences. Using a stochastic dynamic programming model, we show...
The agriculture, forestry and other land use sector are responsible for 24% (10–12 Pg CO2e per year) of anthropogenic greenhouse gas (GHG) emissions worldwide, with concomitant opportunities for mitigation. A scientific panel used deliberative methods to identify ten technical measures comprising 26 sub-measures to reduce GHG emissions from agricul...
Although agriculture could contribute substantially to European emission reductions, its mitigation potential lies untapped and dormant. Market-based instruments could be pivotal in incentivizing cost-effective abatement. However, sector specificities in transaction costs, leakage risks and distributional impacts impede its implementation. The sign...
We argue that “buying local” does not necessarily reduce transport-related greenhouse gas emissions, even if production technologies and yields are homogeneous in space. We develop a partial-equilibrium model of rural-urban systems where the spatial distribution of food production within and between regions is endogenous. We exhibit cases where loc...

This paper provides a quantitative assessment of the effects of input and output prices on French GHG emissions from agriculture, forestry and other land use (AFOLU) at the NUTS3 level. Reduced-form, random-effect spatial error models are estimated for four emissions categories (nitrogen use, manure management, enteric fermentation, and land use, l...
Du fait de son poids dans les émissions de gaz à effet de serre (GES), l’agriculture peut (et doit) participer significativement à l’effort d’atténuation global. Les politiques publiques peuvent jouer un rôle important pour que les potentiels d’atténuation que peut offrir ce secteur soient mobilisés au meilleur coût pour la société. Ce texte synthé...
Buying local food' is sometimes advocated as a means of reducing the 'carbon footprint' of food products. This statement overlooks the trade-off between inter-and intra-regional food transportation. Concentrating food production around large cities might reduce emissions due to interregional food trade, but might increase emissions due to transport...
Meeting future policy targets for bioenergy development worldwide poses major challenges for biomass feedstock supply chains in terms of competitiveness, reliability and sustainability.
This paper reviews current knowledge on the sustainability of agricultural feedstock supply chains and emphasizes future research needs. It covers annual and perenn...
L'usage des sols est une composante majeure de l'adaptation au changement climatique. Comme le changement climatique est susceptible d'affecter les rendements et donc les profits tirés de différents usages des sols, l'adaptation peut induire des changements d'utilisation des sols. Dans cet article, les auteurs examinent les impacts de ces changemen...
Ce texte présentation présente les enjeux économiques liées à l'atténuation et à l'adaptation dans le secteur agricole et forestier.
Given its weight in greenhouse gas emissions (GHG), agriculture can (and should) contribute
significantly to the global mitigation effort. Public policies may play an important role in realizing the
mitigation potential in this sector at the lowest possible cost for the society. This text provides an
overview of the concepts used in applied economi...

As the principal cause of climate change, reducing net greenhouse gas (GHG) emissions has become a major objective. The agricultural sector will be required to contribute to this objective, along with other economic sectors. But the specific characteristics of agricultural greenhouse gases make them difficult to quantify and control. ADEME (the Fre...
Un objectif d'incorporation de 10 % d'énergie renouvelable en 2020 a été fixé pour le secteur des transports au niveau européen. Les biocarburants représentent la solution la plus largement disponible pour atteindre cet objectif. En 2010, ils étaient incorporés à hauteur de 6,7 % dans les carburants français. Un débat existe toutefois sur leurs bén...

Etude réalisée pour le compte de l’ADEME par l’INRA (contrat 10-60-C0039)
In a recent article, Ancev (2011) argues that mandating agriculture in a greenhouse gas (GHG) emission
trading scheme (ETS) would not be socially beneficial, because of high abatement and transaction costs in
agriculture. We re-examine this conclusion by assessing the costs and benefits of extending the coverage
of the EU ETS to agriculture in the...
We propose a quantitative assessment of the marginal abatement costs (MAC) of greenhouse gas emissions
from European agriculture and analyze the implications of the non-ETS burden-sharing agreement (BSA) for
this sector. This assessment is based on MAC reduced forms, the generic specification of which enables simple
parameterization and numerical c...
Recently, an active debate has emerged around greenhouse gas emissions due to indirect land use change (iLUC) of expanding agricultural areas dedicated to biofuel production. In this paper we provide a detailed analysis of the iLUC effect, and further address the issues of deforestation, irrigation water use, and crop price increases due to expandi...
This paper addresses the question of summer cover crop adoption by farmers in presence of a risk of yield loss due to take-all disease and climate variability. To analyze the public incentives needed to encourage farmers to adopt summer cover crops as a means of reducing N leaching, we combine outputs from an economic, an epidemiological and an agr...

This study compares the two most frequently used biofuel policies at the international level (a biofuel subsidy and a biofuel mandate), with a traditional tax policy on gasoline and a benchmark case of a laissez-faire solution (absence of biofuel as an energy source). The first three policy options are usually introduced to reduce greenhouse gas (G...
This text reviews the assessments of marginal abatement costs of methane and nitrous oxide emissions from agriculture. We use agricultural emissions and the corresponding prices collected from 21 studies that have assessed abatement potentials and costs using various modeling approaches and assumptions. We first highlight the implications of the mo...
This work analyzes alternative designs of agri-environmental schemes and how different incentive mechanisms impact on their overall efficiency. It focuses on spatial targeting and delegation in an asymmetric information context. First, the optimal contract under adverse selection is modeled.

Document de communication faisant suite au rapport “Projections d’émissions / absorptions de gaz à effet de serre dans les secteurs forêt et agriculture aux horizons 2010 et 2020”, coordonné par A. Thomas et S. De Cara
We address the issue of the design of climate policy in a dynamic, multigreenhouse gas context. Despite well-established shortcomings, the Global Warming Potential (GWP) is the most commonly used index to compare greenhouse gases. We first review the shortcomings of the GWP from an economic perspective and investigate some possible reasons for its...
Leading economists offer theoretical, quantitative, and policy perspectives on climate policy.
Debates over post-Kyoto Protocol climate change policy often take note of two issues: the feasibility and desirability of international cooperation on climate change policies, given the failure of the United States to ratify Kyoto, and the very limited in...
When the automobile was developed near the beginning of the last century, it was the relatively new fuel gasoline, not the familiar ethanol that became the fuel of choice. We examine the intersections of the early development of the automobile and the petroleum industry and consider the state of the agriculture sector during the same period. Throug...
Land use is a key factor to social wellbeing and has become a major component in political negotiations. This paper describes the mathematical structure of the European Forest and Agricultural Sector Optimization Model. The model represents simultaneously observed resource and technological heterogeneity, global commodity markets, and multiple envi...
Les secteurs agricoles et forestiers ont joué un rôle prépondérant dans la baisse des émissions françaises depuis 1990, année de référence pour le Protocole de Kyoto. Dans un contexte où le régime "post-Kyoto" est en cours de négociation, se pose la question de leur place dans les objectifs nationaux de réduction à l'horizon 2020. Le rapport offre...
We use an updated version of the model described in De Cara et al. (2005) to assess marginal abatement costs of agricultural emissions and analyze the mitigation potential of carbon-friendly tillage prac-tices. Without any specific incentive to adopt alternative tillage practices, agricultural emissions are reduced by 4% at a 20 e/tCO2eq price. Mar...
Agriculture significantly contributes to emissions of greenhouse gases in the EU. By using a farm-type, supply-side oriented,
linear-programming model of the European agriculture, the baseline levels of methane and nitrous oxide emissions are assessed
at the regional level in the EU-15. For a range of CO2-equivalent prices, we assess the potential...
Pour traiter des impacts environnementaux des productions agricoles, les modèles économiques doivent mieux prendre en compte la relation entre les inputs (engrais, alimentation animale), les outputs et l'environnement. Les auteurs présentent une approche intégrée, qui introduit des fonctions de réponse des rendements à la fertilisation azotée dans...
We investigate the impacts of multilateral removal of all border taxes and farm programs and their distortions on developing
economies, using a world agriculture partial equilibrium model. We quantify changes in prices, trade flows, and production
locations. Border measures and farm programs both affect world trade, but trade barriers have the larg...
In this study, we examine the spatial and dynamic implications of policies aimed at increasing carbon sequestration in agricultural soils. We consider incentive mechanisms designed to encourage the planting of energy multi-annual crops that allow higher carbon sequestration rates for a longer period of time. By using a dynamic micro-economic model,...
Agriculture contributes significantly to the emissions of greenhouse gases in the EU.
