Case Studies

Various green demand stimulation policies have been implemented across geographies, sectors and jurisdiction levels (e.g. at the national or city level). These case studies provide a deeper insight into how they have been designed and the impact created.

Case study

ReFuel EU Aviation

Mandatory Quotas
Jurisdiction
European Union
Adopted
2023
Applies to
Flights departing EU airports

ReFuel EU is the European Union’s SAF blending mandate. It sets blending quotas for SAF, where fuel suppliers must incorporate 2% of SAF by volume into jet fuel supplies by 2025, rising to 70% by 2050. From 2030, 1.2% of fuels must be synthetic fuels. This increases to 35% in 2050.

Case study

Renewable Energy Directive (RED) III

Mandatory Quotas
Jurisdiction
European Union
Adopted
2023
Applies to
Industrial hydrogen users

RED requires member states to ensure that at least 42% of hydrogen used in the industry by 2030 is green - rising to 60% in 2035. By 2025, member states must transpose these targets into national law and choose a range of implementation options.

Case study

California Low Carbon Fuel Standard

Transportation Fuel Standard Programmes
Jurisdiction
United States
Adopted
2011
Applies to
Transport (including aviation on an opt-in basis)

The California Low Carbon Fuel Standard aims to decrease the carbon intensity (CI) of transportation fuels, while offering consumers a range of low carbon and renewable fuel options, thereby reducing GHG emissions and improving the air quality in California.

Case study

RE2020 (Environmental Regulation 2020)

Embodied Carbon Limits For Basic Materials
Jurisdiction
France
Adopted
2022
Applies to
Building materials

RE2020 aims to: firstly, improve energy performance and decarbonisation of operations-related energy consumption; secondly, reduce the lifecycle emissions of buildings; and finally, guarantee thermal comfort in case of heatwaves.

Case study

Canadian Policy on green procurement

Green Public Procurement (GPP)
Jurisdiction
Canada
Adopted
2022
Applies to
Steel and cement

In order to support overall Government emissions reductions targets sets requirements to use low carbon concrete, structural and reinforcement steel, and to develop whole-building level life-cycle assessments (to optimise design and material use). This includes a standard to reduce emissions from ready-mix concrete used in major government projects, and to reduce the embodied carbon of major construction projects by 30%.

Case study

H2Global’s first auction

State-Backed Intermediaries
Jurisdiction
Germany
Adopted
2022
Applies to
e-methanol, e-ammonia and e-SAF

H2Global aims to stimulate the market for green hydrogen and its derivatives. Through its subsidiary, Hintco, H2Global has implemented a double-sided auction with hydrogen derivative producers and offtakers.

Case study

EU ETS and CBAM

Carbon Pricing
Jurisdiction
European Union
Adopted
2005
Applies to
Power, industry, aviation, maritime

The EU ETS is the world’s largest carbon pricing system. It works by issuing a capped number of emission allowances (EUAs) that represent one tonne of CO₂e emissions.

Case study

National Green Hydrogen Mission – Pilot Projects

Demand-Side Subsidies & Tax Credits
Jurisdiction
India
Adopted
2023
Applies to
Industry and transport

Under the National Green Hydrogen Mission, the government supports pilot projects in targeted sectors (including steel and maritime), offering subsidies to build infrastructure that enables the uptake of green hydrogen and its derivatives.

Case study

Carbon Contracts for Difference (CCFDs)

Demand-Side Subsidies & Tax Credits
Jurisdiction
Germany
Adopted
2024
Applies to
Heavy industry

In 2024, Germany launched a €4bn auction for CCFDs as the first step of a programme expected to ultimately be much larger. This supports the use of low carbon inputs such as green hydrogen.

Case study

Seattle Priority Green Expedited Programme

In-Kind Incentives
Jurisdiction
United States
Adopted
2009
Applies to
Building materials

Seattle Priority Green is a voluntary programme where building projects receive in-kind incentives for meeting an environmental criteria. Developers can enjoy priority for permit approvals, saving at least three months (roughly 50%) from intake to issuance.

The ITA is a global multistakeholder initiative to catalyse decarbonisation across heavy-emittingindustry and transport sectors, that represent a third of global emissions. With expansive networksacross industry, financial institutions, and governments, the ITA brings together global leaders to unlock investment at scale, for the rapid deployment of decarbonisation solutions.

‍

Within three years, it aims to significantly grow the pipeline of commercial-scale, clean industrial projects to reduce emissions by 2030 and enable delivery of Paris Agreement-aligned ambition for these sectors.
