The impacts of the climate crisis are already perceptible today. Heat records, storms, droughts and floods are threatening ecosystems, biological diversity and the existence of millions of people. The world is facing enormous challenges here. The Paris Climate Agreement seeks to limit global warming to 1.5 degrees Celsius. Germany has signed the climate agreement and derived a regulatory framework from it: According to the Climate Protection Act, there is the binding requirement to achieve greenhouse gas neutrality by 2045. In addition, the company is calling for increasingly strong climate protection measures, as shown by movements such as Fridays for Future.
Consumers, employees and specialist stakeholders of the REWE Group rate the topic as particularly significant for the company as part of the materiality analysis: They want climate protection to be taken into consideration at all levels (for more information, see Materiality Analysis).
In addition to the circular economy and biodiversity, the topic of climate is also a focus issue in the area of action of the environment within the Green Products Strategy 2030.
Background
Climate change is also having economic consequences in the food sector and raw material production. Agriculture is at great risk of suffering damage and loss due to extreme weather events. Temperature fluctuations, heavy rainfall and frequent extreme weather are reducing yields. This also can lead to reduced supplier reliability.
According to the World Economic Forum, 25 per cent of all global greenhouse gas emissions are caused by the supply chains of the food industry. In the European retail trade, emissions from the upstream supply chain represent the largest share (90 per cent) of total emissions in this sector. Therefore, they are fundamentally important for companies when it comes to climate protection. Consequently, the REWE Group has defined a climate strategy for the upstream supply chain.

Management approach
Principles
In its Guidelines on Sustainable Business Practices, the REWE Group commits to continuously reducing the greenhouse gas emissions resulting from business processes.
In 2009, the commercial company had already published its first climate goal at company level and this has been updated since then (for more information, see Climate Protection at Company Level). However, the REWE Group also wants to reduce climate-relevant emissions along the supply chain. Consequently, the company has defined a climate strategy for the upstream supply chain. This was adopted in 2020 and laid down in the Guideline on Climate Protection in the Supply Chain at the start of 2022.
Implementation
The three principles “Avoidance first, then reduction, then compensation” form the framework for the climate strategy in the supply chain at the REWE Group.
Avoidance:
The REWE Group's top priority is to avoid the emission of climate-damaging greenhouse gases along the upstream supply chain of its products, wherever this is possible. Particularly for products which have a high impact on the climate, this is to be achieved, for example, by substituting products or raw materials, avoiding deforestation, or eliminating packaging or packaging components. An example is plant-based alternative products which have lower emissions due to the elimination of greenhouse gases which are produced in animal husbandry.
Reduction:
Where it is not possible to avoid emissions, the REWE Group wants to reduce them through the use of more climate-friendly raw materials and production methods, more environmentally friendly packaging, or shorter transport routes. Examples include the use of deforestation-free feed or recycled paper instead of virgin fibres.
Compensation:
The REWE Group plans to compensate, i.e. offset, any remaining emissions which cannot be avoided during the obtaining of raw materials, their processing, or the transport of products, by promoting climate protection projects. These projects are to be verified or certified in accordance with a recognised standard.
With regards to climate protection in the supply chain, the REWE Group has set strategic goals which give the Group's commitment clear orientation in terms of making product ranges more climate-friendly. Here it has used the requirements of the Science Based Targets Initiative – an alliance of the UN Global Compact, World Resources Institute and WWF – as guidance. This internationally recognised standard helps companies to develop science-based climate goals which are in line with the Paris Climate Agreement.
Similar to the approach for more responsible supply chains, the REWE Group pursues a four-stage process in its climate strategy for the supply chain in order to achieve its objective: Product Range and Risk Analysis, Derivation of Focal Points, Implementation and Measures, Monitoring and Reporting.
Climate-relevant greenhouse gases are produced in all supply chains of the REWE Group, both upstream and downstream. Scope 3 emissions from the upstream supply chain make up the largest share: 62 per cent is attributable to raw materials production (including agriculture), 24 per cent to processing, 6 per cent to packaging and 8 per cent to transport.

The evaluation of the product range and risk analysis revealed a highly fragmented footprint. The REWE Group identified nine product groups which, owing to their high impact on the climate, are the initial focus when deriving measures to reduce the carbon dioxide equivalent footprint: milk and dairy products, sausage, cheese, poultry, eggs, pork, beef, fruit and vegetables. Animal products make up around 42 per cent of the footprint in the product range of the REWE Group, plant products (in this case: fruit and vegetables) 12 per cent. Even though plant-based products generally have a significantly lower greenhouse gas intensity than animal products, they also need to be taken into consideration in the sum of greenhouse gas emissions due to the rising demand from customers.
The strategic approach for climate protection in the supply chain is implemented on three levels:
Firstly, the Group promotes climate protection in the supply chain among the general public by defining specific goals. In addition, it gives its suppliers clear recommendations for action, from which long-term binding requirements are to develop. These relate to categories such as energy, agriculture or waste and call for the deployment of more efficient technology, the use of more sustainable raw materials, or the promotion of the circular economy.
Furthermore, the identification and realisation of improvement potentials, both across product ranges and within a specific product range, form the basis for implementing measures which reduce greenhouse gases in the value chain.
In addition, the REWE Group wants to work with its partners along the supply chain to actively help shape and promote the transformation and climate protection in its supply chains in the form of innovation projects.
Measures and projects to reduce greenhouse gas emissions
In order to consistently reduce greenhouse gas emissions in the supply chain of private labels, the REWE Group is implementing a series of different measures, a selection of which is presented below. The company is aware that a continuous expansion of measures is necessary in order to achieve its strategic goals.
For the definition of clear requirements and goals:
Reduction Roadmaps
In order to promote climate protection in the supply chains of its private labels and reduce emissions in a targeted manner, the Group is developing, in a first step, “reduction roadmaps” for the nine product groups which have a particularly high impact on the climate. These are to be continuously expanded and adjusted, and are also planned for all other product groups.
Deforestation-free supply chains
The REWE Group is aiming to make its supply chains deforestation-free in the areas of wood/paper, palm oil and soy in animal feed by the end of 2025. The company has set specific goals to achieve this. For more information, see Raw Materials in Focus – Food and Raw Materials in Focus – Non-Food. By doing this, the REWE Group wants to reduce the carbon dioxide equivalent footprint in the supply chain.
Rewetting and protection of peat bogs with NABU and peat-free soils
When wet, peat bogs store a quarter of terrestrial carbon, even though they occupy just three per cent of the global land area. Therefore, the REWE Group is involved in the preservation and rewetting of peat bogs. For example, starting in 2022 and for five years, the REWE sales line will pay five million euros each year into the newly created NABU Climate Fund set up by its long-standing partner NABU. The purpose of the NABU Climate Fund is to counteract the drainage of peat bogs caused by agriculture and peat cutting and therefore the release of large amounts of greenhouse gases. In order to achieve this, the water levels on the land will be raised, thereby bringing the degradation of peat to a stop. The focus of climate projects lies in northern Germany and EU countries in the Baltic region. Drained peat bog areas are to be purchased or leased, or farms are to receive support with switching over to climate-friendly wetlands management.
In addition, the REWE Group is switching its entire soil product range – both private labels and brand products – at REWE, PENNY and toom Baumarkt DIY stores over to peat-free alternatives by the end of 2025. By eliminating peat, the REWE Group is reducing the emission of greenhouse gases from drained peat bogs. toom Baumarkt DIY stores also plan to replace peat with alternative materials for ornamental plants. For more information, see Raw Materials in Focus – Non-Food.
Packaging
By the end of 2030, the REWE Group plans to make all sales and service packaging of private labels at REWE, PENNY and toom Baumarkt DIY stores more environmentally friendly. This enables greenhouse gas emissions to be avoided, by saving plastic or using recycled materials, for example. For more information, see Packaging.
For the identification and realisation of improvement Potentials:
Online platform to support suppliers
As part of its strategic suppliers commitment goal (see Goals), the REWE Group is asking its private label suppliers to develop climate goals and measures which are in line with the requirements of the Science Based Targets Initiative. The “REWE Group Initiative – Together for More Climate Protection” helps the Group to monitor this commitment and provides support when it comes to sharing knowledge. For example, it enables suppliers to identify reduction potentials, formulate their own climate goals, and derive corresponding measures. In this way, the REWE Group would like to pool forces through dialogue with its suppliers to achieve ambitious climate protection objectives. The online platform is to be continuously further developed.
For transformation through innovation projects:
PRO PLANET greenhouse
For PRO PLANET greenhouse crops such as peppers, tomatoes and strawberries, REWE and PENNY use a resource-conserving cultivation method in particularly sustainably operated greenhouses in Germany. Renewable energies are used here, thus reducing greenhouse gas emissions.
Dialogue within the sector
The REWE Group communicates regularly with suppliers, industry associations and NGOs on pioneering climate protection activities in the supply chain in order to identify and implement innovative approaches for more climate-friendly production methods. In addition, the Group is committed to promoting industry-wide solutions.
