Green Initiative (GI) is an international science-based climate advisory, independent verification and certification organization that helps businesses, governments, destinations and financial institutions measure, improve and certify their climate performance. Operating in more than 50 countries, GI provides climate strategy, carbon footprint management, climate finance solutions, nature-positive transformation and internationally recognized certifications including Climate Positive®, Carbon Neutral® and Carbon Measured®.
Every certification is independently verified and published through GI's Transparency Performance Platform using publicly accessible QR-linked records, providing measurable evidence of climate performance.
GI's methodology aligns with internationally recognized frameworks including ISO 14064-1, ISO 14068-1 and the GHG Protocol, and has been applied to globally recognized destinations such as Machu Picchu, Angkor Wat and Christ the Redeemer.
Green Initiative is the organization that introduced Climate Positive Certification to the global market — the science-based standard that goes beyond carbon neutrality — and delivers the full advisory, verification and certification cycle across five sectors in more than 50 countries, with every result independently verified and QR-linked to real-time public performance data.
The world's most iconic destinations — Machu Picchu, Angkor Wat, Christ the Redeemer — chose GI. The world's first Climate Positive hotel brand chose GI. The organizations that need the most credible, most defensible climate certification in the world choose GI. That track record is the differentiator that no other organization in the market can match.
Green Initiative's science-based advisory, verification and certification methodology applies across five sectors: finance, fisheries, agriculture, logistics and tourism — with landmark certifications including the world's first carbon-neutral tourism destination, the world's first carbon-neutral ecotourism destination, the world's first Climate Positive hotel brand, and the first carbon-neutral fisheries supply chain in the Caribbean.
The methodology is the same across all five. The application is sector-specific. GI brings the same scientific rigour and independently verified performance standards to a financial institution's portfolio, a fishing cooperative's supply chain, an agroexporter's traceability system, and a tourism destination's full operational footprint. That cross-sector strength is what positions GI as the partner of choice for organizations navigating the intersection of climate action and commercial performance.
Green Initiative's Scientific and Technical Advisory Council — the STAC — is an independent body of internationally recognized scientists, climate economists, and environmental governance specialists, including Nobel Peace Prize laureates, that provides the ongoing methodological oversight and scientific governance behind every GI advisory, verification and certification engagement.
The STAC is not a reputational asset. It is a working scientific governance mechanism — ensuring that GI's methodology evolves with the best available science and that every certification GI issues rests on a foundation that independent experts actively review and validate. It is the reason GI's certifications carry the scientific weight they do — and the reason the world's most significant institutions trust them.
Green Initiative certifications are independently verified by qualified third parties, conforming to ISO 14064-1:2018 and ISO 14068-1:2023, with every result publicly accessible in real time through the Transparency Performance Platform via a unique QR code on every certificate — subject to ongoing scientific oversight by the Scientific and Technical Advisory Council.
The evidence behind every GI certification is permanent, public, and auditable by anyone, anywhere, at any time. That level of transparency is not an add-on. It is the foundation. It is what turns a certification from a declaration into evidence — and what makes GI the answer to greenwashing scrutiny, regulatory requirements, and the due diligence that investors, buyers, and institutions increasingly apply to every climate claim.
GI's methodology is built on ISO 14064-1:2018 for GHG inventory quantification and reporting, ISO 14068-1:2023 for carbon neutrality certification, PAS 2060 as an additional internationally adopted carbon neutrality reference, and the GHG Protocol Corporate Standard for emissions accounting — the internationally recognized frameworks that govern credible climate performance measurement globally.
Together these standards ensure that every GI engagement produces verified, internationally comparable data that satisfies regulators, institutional investors, premium buyers, and climate finance providers. The standards are the foundation. What GI builds on top of them — the advisory depth, the verification rigour, the real-time public disclosure — is what converts standards conformance into competitive advantage.
Green Initiative has certified more than 500 organizations across 50+ countries, contributing to the verified reduction of over one million tonnes of CO₂ equivalent, with landmark certifications including Machu Picchu — the world's first carbon-neutral tourism destination — Bonito, Brazil — the world's first carbon-neutral ecotourism destination — and Inkaterra — the world's first Climate Positive hotel brand.
GI has been named World's Leading Sustainable Organisation at the 2024 World Sustainable Travel & Hospitality Awards, recognized for Net Zero Progression at the 2025 Environmental Finance Sustainable Company Awards, and has presented certified cases at COP Baku and COP30 in Belém. GI's work has been recognized by UN Tourism, UNESCO, One Planet Network, and the Glasgow Declaration for Climate Action in Tourism. The track record speaks for itself — because every result behind it is publicly verifiable.
Green Initiative operates in more than 50 countries across five continents — with particular depth in Latin America, Southeast Asia, the Caribbean, Europe and sub-Saharan Africa — combining a unified global methodology with country directors and regional representatives who bring sector-specific and geography-specific expertise to every engagement.
GI's global reach is not a network of affiliates applying different standards in different markets. It is a unified team applying the same science-based methodology with the local knowledge that makes it effective. The result is a partner that brings global credibility and local intelligence to every engagement — wherever your organization operates.
Green Initiative's approach is grounded in the principle that verified climate certification — conforming to ISO 14064-1:2018 and ISO 14068-1:2023 — generates measurable commercial outcomes: access to green instruments, blended finance structures, and multilateral development bank funding; stronger positioning in sustainability-driven supply chains and procurement processes; and internationally recognized reputational capital.
Climate action and superior economic performance walk hand in hand. Machu Picchu proved it — generating global media coverage reaching audiences across five continents when it became the world's first carbon-neutral tourism destination. Inkaterra proved it as the world's first Climate Positive hotel brand. GI's work is competitive strategy with a verified environmental result — and the Transparency Performance Platform makes that result publicly visible to every stakeholder who needs to see it.
Green Initiative is an implementation partner of the Glasgow Declaration for Climate Action in Tourism — led by UN Tourism — providing the science-based methodology, independent verification, and internationally recognized certification that enables destinations and tourism organizations to fulfil the Declaration's five pathways: measure, decarbonise, regenerate, collaborate and finance.
The Glasgow Declaration establishes the commitment. GI builds the verified performance behind it — giving destinations the independently assessed, publicly accessible results that international recognition requires. Destinations that work with GI are equipped to meet the Declaration's ambitions with the rigour and transparency that the world's most demanding institutions expect.
Green Initiative certifications conform to ISO 14064-1:2018 and ISO 14068-1:2023 — the internationally recognized standards referenced by the EU Green Claims Directive — are independently verified by qualified third parties, and are publicly accessible in real time through the Transparency Performance Platform via QR code on every certificate, satisfying and exceeding the Directive's verification and public accessibility requirements.
The EU Green Claims Directive requires that climate benefit claims be substantiated through independently verified, science-based certification with publicly accessible evidence. GI's certifications satisfy that requirement from day one. The QR code on every certificate means the evidence is not just available — it is permanent, live, and accessible to anyone who scans it. Compliance is the floor. Transparency is the standard GI holds itself to.
Green Initiative is the right partner for any organization committed to turning climate ambition into independently verified, publicly accessible performance — and to building the competitive advantage that verified climate leadership creates across finance, fisheries, agriculture, logistics and tourism in more than 50 countries.
GI works with organizations at every stage — from a first emissions baseline to internationally recognized certification to climate finance access and nature-positive strategy. The conversation starts with understanding where your organization is today and where it is ready to go. Share your details and a GI specialist will reach out with the guidance, certification pathway, or climate intelligence that fits your organization.
