EU EPR extends to digital services，website service providers need to open carbon data interfaces

On July 1，2026，the European Commission announced that the Extended Producer Responsibility（EPR）system would be extended to B2B digital service platforms，covering businesses such as website building and SaaS marketing tools。According to the disclosed content，from Q4 2026，Chinese suppliers providing website building services to EU enterprises will need to open API interfaces in their backend systems，allowing customers to retrieve annual carbon emissions data for modules such as website hosting，CDN，and email marketing，in order to support customers in fulfilling disclosure obligations related to the EU Green Claims Directive。For website building service providers，SaaS tool providers，buyers，and delivery processes，this change deserves attention，because its impact has extended from traditional product responsibility to the compliant delivery capability of digital services。

What has been clarified by this rule change

Confirmed information shows that the European Commission announced on July 1，2026，that the EPR system would be formally extended to B2B digital service platforms，with the scope covering service types such as website building and SaaS marketing tools。

At the same time，the confirmed implementation requirement is：from Q4 2026，Chinese suppliers providing website building services to EU enterprises must open API interfaces in their backend systems，allowing customers to extract annual carbon emissions data for the service modules they use。The modules listed in the summary include website hosting，CDN，and email marketing。

The purpose of using this interface has also been clarified，namely for customers to fulfill disclosure obligations under the EU Green Claims Directive。The input information mentions examples of Chinese suppliers，but does not provide further implementation details，calculation scopes，or file format requirements。

Where the impact first falls in the delivery chain

The backend capabilities of website building and SaaS service providers will be directly tested

From an industry perspective，the suppliers most directly affected are those providing website building services，marketing tools，or related digital services to EU enterprises。The reason is that the rule change not only involves compliance commitments at the contract level，but also specifically comes down to whether the backend system can open APIs and whether it can output annual carbon emissions data by module。

This means that the changes relevant enterprises need to focus on have already extended from traditional service delivery，function development，and operations and maintenance support to data interfaces，carbon emissions information organization，and customer retrieval capabilities。For service providers bidding，renewing contracts，or delivering services to EU enterprises，interface capability may become a practical step in customers’ review of service availability and compliance。

Buyers’ requirements for supplier materials may move forward

Procurement processes for EU enterprises may also be affected。From an analytical perspective，since customers need to use supplier interfaces to fulfill disclosure obligations，then during procurement，selection，or renewal stages，what deserves more attention is not only price，functionality，and delivery cycle，but also whether the supplier can provide the corresponding capability to retrieve carbon emissions data。

Such changes may be reflected in adjustments to procurement documents，supplier admission materials，technical integration checklists，or delivery acceptance conditions。Although the input information does not provide specific templates or implementation scopes，communication between buyers and suppliers around interfaces，data availability，and annual disclosure support is expected to become one of the practical priorities。

Pressure on collaboration between supply chain services and operations and maintenance will increase

For participants in the service chain responsible for delivering modules such as hosting，CDN，and email marketing，this change may also bring collaboration pressure。The reason is that what customers need is not an abstract compliance statement，but annual carbon emissions data that can be used for disclosure。If services are delivered through a combination of multiple modules，data aggregation，module boundary division，and consistency of interface output will all affect the final delivery quality。

From observation，this type of impact leans more toward delivery organization and information flow management。Even though the rule targets customer-facing interface requirements，actual implementation may still require service providers to sort out internal data sources，module attribution，and external output paths。

Which practical issues enterprises should pay closer attention to now

First confirm whether interface obligations enter contracts and delivery lists

For relevant suppliers，what deserves more attention at present is whether this requirement will be further written by customers into contract terms，tender documents，technical annexes，or service level agreements。If the capability to open interfaces becomes part of EU customers’ performance of disclosure obligations，then its legal and delivery attributes will no longer be merely a value-added service，but may become a basic supporting condition。

Sort out the retrievable data scope as soon as possible

The input information has clearly mentioned annual carbon emissions data for modules such as website hosting，CDN，and email marketing。Therefore，what enterprises need to focus on is not generic low-carbon statements，but whether the current backend has the ability to identify，aggregate，and output relevant annual data by module。If the existing system only supports business statistics but does not support corresponding interface retrieval，subsequent transformation pressure may be concentrated at the delivery front end。

Continue to monitor implementation scopes rather than rush to conclusions

Because the existing input does not provide more detailed calculation rules，data formats，review methods，or exceptions，enterprises should not directly treat a certain internal understanding as the final implementation standard at this stage。A more prudent approach is to continue monitoring subsequent official statements，customer requirements，and changes in specific business documents，especially technical requirements connected with disclosure obligations。

Include after-sales support as part of compliance services

From an analytical perspective，this change affects not only the initial launch or first delivery。As long as customers need to retrieve data annually and use it for disclosure，subsequent interface maintenance，data updates，exception handling，and customer support by service providers may also become part of compliant delivery。For long-term service contracts，whether after-sales response covers this type of data retrieval demand is worth incorporating into service arrangements in advance。

This is more like an implementation signal，rather than all details being finalized

From observation，the core signal conveyed by this information is that digital services have been included in a more specific responsibility and disclosure chain，especially for suppliers providing services to EU enterprises，whose backend capabilities are being incorporated into customers’ compliance systems。

However，it should also be noted that the currently known information is closer to a clear direction and initial requirement，and does not mean that all implementation details have been fully expanded。Regarding data scopes，review methods，document alignment，and market feedback，the input has not yet provided further information。Therefore，it is more appropriate to understand this as the rules having sent a clear implementation signal，while the specific pace of implementation still needs continued observation。

How the industry should understand this change

Overall，the industry significance of this change lies in the fact that the requirements of relevant EU rules for corporate responsibility have continued to extend from physical products to digital service delivery processes。For website building service providers，SaaS tool providers，and relevant procurement entities，API opening and carbon emissions data retrieval capabilities are becoming new compliance concerns。

At present，it is more appropriate to understand this information as an implementation change with a clear direction，and also as a regulatory signal whose subsequent implementation details，customer documents，and industry feedback still need to be continuously tracked。Enterprises at this stage need to pay attention to its impact on system delivery，procurement requirements，and customer service methods，but should also avoid making overly definitive judgments when the details are not yet clear。

Basis of this article and directions for subsequent verification

This article is generated based on the information title，event occurrence time，and event summary provided by the user，and the confirmed factual scope is limited to the relevant input content。Judgmental content involved in the article is distinguished by methods such as analysis and observation，and is not treated as established fact。

For such events，subsequent verification usually still needs to be continuously conducted in combination with sources such as official announcements，regulatory releases，trade or industry authority information，industry association materials，standards organization documents，and authoritative media reports。Because the input does not provide specific official source links，the relevant links and original documents still need to be further confirmed subsequently。

Content still worth continued observation includes：whether policy details will be supplemented，whether the implementation scope for certification or disclosure will be clarified，whether tender documents and procurement requirements will change，whether industry feedback will tend to be consistent，and how enterprises’ actual implementation will unfold。
