Germany Tightens Rules on Green Advertising as New September Regulations Take Effect
Germany has introduced a series of new rules in September, including tighter requirements for environmental advertising, expanded tax-assistance services and a nationwide railway-station alcohol ban that is being introduced in stages.
The changes were outlined by the German Federal Government as part of its overview of legislation and regulations taking effect during September 2026.
Stricter standards for environmental claims
One of the most significant changes concerns the way companies promote products using environmental claims.
From September 27, businesses will have to provide evidence when using advertising terms such as “environmentally friendly.” Broad claims such as “climate-neutral” or “environmentally friendly” will no longer be permitted without the required substantiation.
The government says the measure is designed to tackle misleading environmental marketing and give consumers clearer information when making purchasing decisions.
The new framework also introduces EU-wide labels related to durability and consumer rights. One label will provide information about the minimum two-year right to repair or replacement, while another will identify additional durability guarantees offered by manufacturers.
Tax assistance rules become more flexible
Another change concerns Germany’s tax advisory system.
Beginning September 1, income-tax assistance associations will be allowed to provide broader support to their members when dealing with tax returns, particularly for income connected with renting and leasing property.
The previous income threshold that restricted this assistance has been removed under the amended rules, giving affected taxpayers access to a wider range of advisory support.
Alcohol restrictions introduced at railway stations
Germany has also begun implementing new restrictions on alcohol consumption at railway stations.
Deutsche Bahn’s nationwide policy is intended to improve safety at stations. From September 1, the prohibition initially applies at Berlin Central Station, Berlin Gesundbrunnen, Kiel and Braunschweig.
The restriction covers station halls and platforms. However, alcohol consumed inside station restaurants remains permitted, and passengers may continue to carry sealed alcoholic beverages. The government says the policy is scheduled to expand progressively to other railway stations through October 15.
Government focuses on modernization and consumer protection
The September measures form part of a wider programme of regulatory changes being pursued by the German government.
Official government information also highlights initiatives involving digitalisation, economic competitiveness, innovation and reducing bureaucracy. A recent cabinet retreat at Neuhardenberg Castle focused on strengthening Germany’s competitiveness and innovation capacity.
Together, the new measures show Germany placing greater emphasis on consumer transparency, regulatory modernization and public safety, while also attempting to reduce administrative burdens in selected areas.
The changes will affect businesses, consumers, taxpayers and railway passengers in different ways as the new rules are implemented over the coming weeks.
