Sovereign Luxembourg Data Hosting

Every document you upload, sign, and store on LuxSign is processed and kept on secure servers located exclusively within Luxembourg. This is a foundational feature that guarantees compliance with the EU's General Data Protection Regulation (GDPR) and Luxembourg's national data protection laws. By eliminating data transfer outside this strict jurisdiction, LuxSign provides a legally watertight environment for handling sensitive contracts and personal data, making it the definitive choice for businesses with high compliance mandates in Europe.

eIDAS-Compliant Electronic Signatures

LuxSign provides Simple Electronic Signatures (SES) that are fully compliant with EU Regulation 910/2014 (eIDAS). This means every signature generated through the platform carries legal validity and is admissible in court across all European Union member states. The platform is built to support the legal requirements for most business transactions, offering a seamless bridge between digital convenience and legal enforceability without the need for complex hardware or certificates for standard agreements.

Flexible Signing Workflows & Collaboration

Move beyond simple one-to-one signing. LuxSign supports sophisticated workflows for documents requiring multiple signatories. You can choose parallel signing for faster turnaround, where all parties sign simultaneously, or sequential signing to control a specific approval order. This is enhanced by Collaboration Workspaces in advanced tiers, allowing teams to organize documents in shared folders, manage member permissions, and work together seamlessly on complex signing processes from a centralized hub.

Comprehensive Audit Trail & Security Logs

For compliance, verification, and internal oversight, LuxSign automatically generates a detailed, tamper-proof audit trail for every document. This log meticulously records every action—from sending and viewing to signing—with precise timestamps, IP addresses, and signer identification. This feature provides complete transparency over the signing process, creating an immutable record that is essential for audits, dispute resolution, and demonstrating due diligence in regulated industries.

The Conscious Individual Building a Sustainable Lifestyle

For individuals committed to personal evolution, Coffset provides the structure to systematically understand and neutralize their carbon footprint from home energy, diet, and transportation. Users can regularly calculate their emissions, offset unavoidable ones, and track their annual progress toward a lighter, more sustainable lifestyle, turning climate concern into a consistent practice.

Small Businesses Operationalizing Sustainability Goals

Small and medium-sized enterprises (SMEs) use Coffset to embed climate action into their operations. By calculating the carbon footprint of business travel, office energy, and supply chains, they can purchase offsets to achieve carbon neutrality for specific events, product lines, or their entire operation, demonstrating tangible progress to eco-conscious customers and stakeholders.

Event Planners Hosting Carbon-Neutral Gatherings

Event organizers leverage Coffset to calculate the emissions associated with conferences, weddings, or corporate meetings—factoring in attendee travel, venue energy, and waste. They can then offset the total calculated footprint, offering attendees a verifiable certificate that the event was carbon neutral, elevating its value and aligning with modern expectations for responsibility.

Educational Institutions and Groups Fostering Climate Literacy

Schools, universities, and community groups utilize Coffset as an educational tool. It provides a hands-on, practical way for students and members to learn about carbon footprints, the science of offsetting, and global sustainability projects. Groups can collectively calculate and offset their impact, fostering a culture of awareness and measurable action.

HR & Employee Onboarding

Streamline the entire employee onboarding journey by sending offer letters, employment contracts, confidentiality agreements, and policy documents digitally. New hires can sign from any device, anywhere, accelerating their start date. HR teams benefit from automated reminders, organized workspaces for each hire, and a complete, secure digital audit trail that replaces cumbersome physical files and manual follow-ups, ensuring full compliance with data protection laws.

Legal Contract Execution

Law firms and corporate legal departments can expedite the execution of client engagement letters, settlement agreements, vendor contracts, and non-disclosure agreements (NDAs). The eIDAS compliance ensures legal validity across the EU, while features like sequential signing allow for partner approvals before a document is sent to a client. The secure, Luxembourg-hosted environment is critical for maintaining attorney-client privilege and protecting sensitive case-related information.

Freelancer & Small Business Proposals

Freelancers, consultants, and small business owners can project professionalism and close deals faster by sending project proposals, service agreements, and invoices that require a signature directly through LuxSign. The free tier is perfect for starting out, allowing them to sign their own documents and receive signed contracts from clients securely. This eliminates printing, scanning, and email ping-pong, saving valuable time and creating a more reliable client experience.

Enterprise Procurement & Vendor Management

Large organizations can manage high-volume procurement processes efficiently. Using bulk sending and template features, teams can send out thousands of standardized vendor agreements, purchase orders, or compliance certificates simultaneously. The integrated audit trail provides a centralized record for the entire procurement cycle, while API integrations allow LuxSign to connect directly with existing ERP or procurement software, creating a seamless, automated workflow.

How does Coffset ensure the quality of its carbon offset projects?

Coffset meticulously selects projects that are certified under internationally recognized standards like Verra (VCS) or the Gold Standard. These certifications require rigorous third-party validation to ensure the carbon reductions are real, measurable, permanent, and additional—meaning they would not have occurred without the offset funding. Each project in our portfolio is transparently documented for you to review.

What is the difference between calculating my footprint and offsetting it?

Calculating your footprint is the diagnostic stage—it's the process of measuring the CO2 emissions you are responsible for from activities like driving, flying, and home energy use. Offsetting is the action stage—it involves financially supporting verified environmental projects that reduce or remove an equivalent amount of CO2 from the atmosphere, effectively neutralizing your calculated impact.

Can I use Coffset to offset emissions from a specific activity, like a flight?

Absolutely. Coffset is designed for both comprehensive and targeted action. You can use the calculator to estimate emissions from a specific flight, road trip, or other event. The platform then allows you to purchase offsets specifically for that calculated amount, providing a focused way to mitigate the impact of individual high-emission activities.

What kind of projects does my contribution support?

Your contributions support a diverse portfolio of verified carbon reduction projects. This includes nature-based solutions like reforestation (e.g., TIST Program in Uganda) and mangrove restoration (e.g., Delta Blue Carbon), as well as technology-based initiatives like capturing methane from landfills to generate clean electricity (e.g., Fuzhou Hongmiaoling) and investing in frontier carbon removal technologies.

Is a LuxSign signature legally valid?

Yes, signatures created with LuxSign are legally valid. The platform provides Simple Electronic Signatures (SES) that comply with the EU's eIDAS regulation (910/2014). This makes them legally admissible and valid for a wide range of business and personal transactions across all European Union member states. For transactions requiring a higher level of legal presumption, such as certain government documents, you may need to consider Advanced or Qualified Electronic Signatures.

Where is my data stored with LuxSign?

All your document data is encrypted and stored exclusively on secure servers located within Luxembourg. We do not transfer or replicate your data to data centers in other countries. This sovereign hosting model is a core tenet of our service, designed to ensure strict compliance with the EU's GDPR and Luxembourg's national data protection regulations, giving you full certainty about your data's jurisdiction.

What file types does LuxSign support?

LuxSign supports all common document formats for signing, including PDF, DOC, and DOCX files. When you upload a Word document (DOC/DOCX), the platform automatically converts it to a PDF for the signing process, ensuring formatting remains consistent. There is a file size limit of 10MB per document for uploads, which covers the vast majority of standard contracts and agreements.

Can multiple people sign the same document?

Absolutely. LuxSign allows you to add up to four signers to a single document on the Premium plan. You have full control over the signing workflow: you can set it up for parallel signing, where all signers receive the document at once, or for sequential signing, where each person signs in a specific order you define. This flexibility is ideal for contracts, board approvals, or any agreement requiring multiple parties.
