Rarely has any topic related to advertising and competition law kept the German courts as busy in such a short period of time as adverts making carbon neutral claims. New and sometimes inconsistent decisions on this topic have been handed down in quick succession leaving advertisers facing a number of questions including:
- Can you advertise something as carbon neutral if the carbon footprint is merely offset by purchasing CO2 emission certificates?
- Can you exclude certain CO2 emissions from the carbon balance calculation?
- What are the advertisers' duties to provide clarification and information?
- How and where does clarification have to be provided - directly on site or is a so-called "media disruption" (“Medienbruch”) permissible as well?
- Can you to link to a website? Is a QR code an option?
German case law on this issue is yet to be settled. At present, a sizable number of proceedings are pending, and more can be expected in the near future. The Federal Court of Justice (Bundesgerichtshof, BGH) is also yet to rule on advertising using the statement "carbon neutral". As a result, advertising a company or products as carbon neutral remains fraught with risks, including of being publicly branded as a 'greenwasher', even where a genuine effort is made to be sustainable.
In 2021, the European Commission carried out a sweep of EU websites to assess the extent to which environmental claims constituted greenwashing. The European legislator consequently identified a need for EU-wide regulation, which is already taking concrete shape - a draft "Green Claims Directive" on substantiation and communication of explicit environmental claims) was published on 22 March 2023 as discussed here.
This EU sweep also led to several German competition associations taking up the fight against greenwashing in Germany. In particular, the “Centre for Protection against Unfair Competition” (Wettbewerbszentrale) and “Environmental Action Germany” (Deutsche Umwelthilfe e.V.) saw fit to issue warnings to a large number of companies for environmental advertising claims and to initiate legal proceedings.
This has resulted in many recent rulings, giving the German courts a somewhat pioneering role in the EU when it comes to carbon neutrality claims made in advertising. The, rulings give advertisers in Germany a little more (if still incomplete) certainty, as a number of trends have emerged.
General principles for Green Advertising in Germany
In Germany, environment-related advertising claims to date have mostly been tested against Sections 5 and 5a of the Act against Unfair Competition (Gesetz gegen den unlauteren Wettberwerb, UWG). These two provisions of German competition law are regularly at issue in court when it comes to advertising using the term 'carbon neutral' or similar terms. All of the cases revolve around the issue of misleading. Whereas Section 5 UWG provides for a prohibition of misleading by (active) deception, section 5a prohibits misleading by leaving out material information, (misleading by omission).
The highest German civil court (BGH) has a history of making landmark decisions on environmental advertising, and has found that consumers have an interest in being informed about environmental effects. The requirements established by the BGH for environmental advertising and the duty to provide information set a high bar (in particular BGH, judgment of 20 October 1988 – I ZR 238/87 – “Aus Altpapier” (Made from waste paper), BGH, judgment of 14 December 1995 – I ZR 213/93 – “Umweltfreundliches Bauen” (Environmentally friendly construction), BGH, judgment of 05 December 1996 – I ZR 140/94 – “Umweltfreundliche Reinigungsmittel” (Environmentally friendly detergents)).
The BGH established that since vague environmental claims (eg 'environmentally friendly', 'sustainable' etc.) have a high potential to mislead, they also require special protection against misleading statements. As a consequence, generally speaking, environmental advertising in Germany must be assessed strictly and restrictively. Extensive duties to provide information and explanations are imposed on advertisers.
This does not mean there is a general and comprehensive duty to provide information about other/all disadvantages of a product. The BGH established this in its 1996 ruling on the term “PVC frei” ("free from PVC") (BGH, judgment of 23 May 1996 - I ZR 76/94 – “PVC frei” (PVC free”)). However, this issue needs to be assessed on a case-by-case basis.
Application of these principles to 'carbon neutral' advertisements
These very strict principles of environmental advertising established by Germany's highest courts apply to advertising using the term 'carbon neutral'. As a consequence, many German courts initially found that the meaning of 'carbon neutral' was not clear-cut and therefore required explanation. If such an explanation was missing or inadequate, the courts usually ruled the advertising to be non-compliant.
In 2021 and 2022, a number of rulings were handed down in Germany on advertising using the words 'carbon neutral'. Over time, case law clearly has become ever more specific and differentiated. Some of these rulings dealt with product advertising and some with company-related advertising. Initially, nearly all of the advertising at issue was classified as non-compliant. However, 2022 saw a shift with a number of rulings in favor of the advertising companies.
