Green Policies, Regulations & Standards

IHG’s supplier framework operates as a procurement-driven hospitality governance system combining Journey to Tomorrow, Responsible Sourcing Guidance, IHG Global Procurement, supplier due diligence, HARP, EcoVadis, and Green Engage. It governs suppliers and hotel partners through ethical, social, and environmental expectations, approved supplier access, hotel-level sustainability systems, and 2030 responsible business goals. The strongest obligations apply to approved suppliers, hotel owners, franchisees, F&B suppliers, FF&E providers, construction contractors, laundry providers, amenities suppliers, and waste contractors.

Accor’s supplier framework operates as a contractual hospitality governance system combining the Responsible Procurement Charter, Astore procurement, ESG reporting, Carbon Tracker data, and responsible sourcing. The Charter applies to suppliers, service providers, and subcontractors, requires upstream cascade, audit participation, and corrective action, and may support termination where principles are breached. The framework is strongest in procurement contracts, F&B sourcing, hotel-level emissions data, environmental policies, and supplier compliance monitoring.

CertaLink Energy Certification is a digital certification system developed by Siemens Energy together with TÜV SÜD and the German Energy Agency (dena). The platform uses blockchain-based technology to verify the origin, carbon intensity, and sustainability attributes of products such as renewable electricity, green hydrogen, e-fuels, and other low-carbon commodities. It is designed to support traceability and automated certification across complex energy supply chains.

The EU Medium Combustion Plant Directive (MCPD) establishes emission limits and monitoring obligations for medium-sized combustion plants such as boilers, engines, and turbines with a rated thermal input between 1 MW and 50 MW. Adopted in 2015, the directive aims to reduce air pollution from sulphur dioxide (SO₂), nitrogen oxides (NOₓ), and particulate matter by introducing harmonized EU-wide standards for permitting, emissions monitoring, and compliance reporting.

Turkish Airlines operates a supplier sustainability framework combining its Supplier Code of Conduct Policy, Sustainable Procurement Policy, Environmental Policy, Energy Policy, Climate Transition Plan, CDP climate disclosures, and aviation-sector compliance mechanisms. The framework exists to reduce climate, energy, waste, resource, biodiversity, fuel, and operational impacts across aviation supply chains. It affects fuel suppliers, aircraft and engine manufacturers, maintenance providers, ground handlers, catering suppliers, cargo partners, airport service providers, logistics companies, waste contractors, technology vendors, and Turkish Technic suppliers.

The Worldwide Harmonized Light Vehicles Test Procedure (WLTP) is a global vehicle testing standard used to measure fuel consumption, CO₂ emissions, electric driving range, and pollutant emissions from light-duty vehicles. Developed under the United Nations Economic Commission for Europe (UNECE), the WLTP replaced the older New European Driving Cycle (NEDC) in the European Union and several other jurisdictions to provide more realistic and internationally harmonized vehicle performance data. The procedure applies to passenger cars and light commercial vehicles and is used for vehicle type approval, emissions compliance, consumer information, and regulatory reporting.

Regulation (EU) 2024/1257, commonly known as the Euro 7 emissions standard, establishes the European Union’s latest vehicle emissions and battery durability requirements for cars, vans, trucks, buses, and certain trailers. Adopted in April 2024, the regulation replaces the previous Euro 6 and Euro VI frameworks with a single unified system covering both light-duty and heavy-duty vehicles. Euro 7 expands EU vehicle emissions regulation beyond exhaust pollutants to include brake particle emissions, tire abrasion, and battery durability requirements for electric vehicles. The regulation forms part of the EU’s broader Zero Pollution Action Plan and Green Deal objectives.

RE2020 (Réglementation Environnementale 2020) is France’s environmental building regulation for new construction projects. Introduced to replace the earlier RT2012 thermal regulation, RE2020 expands the scope of building requirements beyond operational energy efficiency to include lifecycle carbon emissions, material impacts, and climate resilience. The regulation applies progressively to residential, office, educational, and other new buildings across metropolitan France. It entered into force beginning in January 2022 and is considered one of the first major national building regulations to integrate lifecycle carbon assessment into mandatory construction standards.

Sinopec’s supplier framework operates as a procurement-driven green industrial governance system. It combines sustainable supply chain management, sunshine procurement, green procurement, supplier admission, evaluation, and exit mechanisms, and carbon peaking and neutrality objectives. Suppliers must provide quality, environmental, safety, and low-carbon evidence that supports Sinopec’s refining, chemical, energy, and engineering operations. The framework is less CDP-style and more industrial-procurement focused, making supplier eligibility dependent on compliance, performance, green materials, efficient technologies, and environmental credibility.

Qatar Airways operates a supplier governance framework that combines its Supplier Code of Conduct, Environmental Sustainability Policy, e-procurement controls, sustainability reporting, climate and energy strategy, SAF engagement, carbon offsetting, and compliance with aviation market-based measures such as CORSIA, EU ETS, and UK ETS. The framework exists to reduce climate, resource, waste, biodiversity, fuel, catering, logistics, and operational impacts across aviation supply chains. It affects aircraft and engine suppliers, fuel suppliers, SAF providers, ground handlers, airport service providers, catering suppliers, cargo partners, waste contractors, technology vendors, logistics providers, travel service suppliers, and maintenance contractors.
