Does more sustainable food increase consumer budgets?

14 October 2021 - Climate Brief - By : Lucile ROGISSART / Valentin BELLASSEN / Claudine FOUCHEROT

Consuming less animal products and wasting less lighten the budget, but increasing consumption of organic products adds to it. In total, does adopting a sustainable diet increase or decrease consumer spending?


Report available in French only


While some studies give a clear-cut answer to this question, it actually varies according to at least three factors:

  • The ambition of the sustainable diet: the level of substitution between animal and plant proteins, the share of sustainably produced products (which is simplified to organic), and the level of waste reduction;
  • The economic conditions, in particular the price of organic products compared to conventional products;
  • The initial base of consumers and the prices at which they buy their products, which are strongly correlated with income.


I4CE has developed a calculator to measure the effects of each of these factors on the household food budget. Depending on the level of these parameters, the transition to a more sustainable diet can range from a 30% gain to an additional 67% of the consumer’s initial food budget. People with the lowest incomes have the highest potential additional costs.


At current prices, regardless of reductions in animal products and waste, consuming mostly organic food is more expensive, especially for the poorest households. The price premium for organic over conventional would have to fall from 65% today to 10% for all households to be able to adopt a less meaty 100% organic diet without increasing their budget.


If a high consumption of organic products is targeted, public policies must therefore manage the tension between remunerative prices for sustainable farming practices and an increase in food expenditure acceptable to households.

    European Carbon Certification must be demanding… and appealing

    How can we differentiate between projects that really enable carbon to be stored and those that only claim to do so? This is a complicated question when dealing with projects in agriculture and forestry, where quantifying carbon storage is complex, and where other environmental challenges, like the preservation of biodiversity, must also be taken into account. A complicated question, therefore, but one that needs an answer! Private actors and public authorities want to ensure that the agricultural and forestry projects financed in the name of the climate have a real environmental benefit.

    Carbon certification: the Commission publishes a stringent certification framework that should also be appealing

    Yesterday, 30 november 2022, the European Commission adopted a proposal for a first EU-wide voluntary framework to reliably certify high-quality carbon removals. This proposal provides a framework, broad guiding principles, and the details will be specified in 2023 supported by an expert group on Carbon Removals. “The devil may be in the detail”, but the framing is no less important. Claudine Foucherot of [i4ce] has analysed it and identified four points on which we must be vigilant. Overall, it can be said that the Commission is submitting an ambitious proposal, which nevertheless presents a risk: not being sufficient incentives to ensure a massive deployment of certified projects.

    Op-ed | Payment for carbon farming: we need an ambitious and pragmatic European certification

    The European Commission will propose a `carbon certification’ by the end of the year as a first step towards remunerating farmers and foresters who contribute to carbon farming. This certification project raises debates and concerns. For Adeline FAVREL of I4CE, the EU can respond and develop an ambitious certification by relying on the experience of the Member States in this field.
