Industrial Deep Decarbonisation Initiative



Stimulating global demand for low carbon industrial materials by: 

  1. Encouraging governments and the private sector to buy low carbon steel and cement, and
  2. Sourcing and sharing data for common standards and targets



The Clean Energy Ministerial Industrial Deep Decarbonisation Initiative (IDDI) is a global coalition of public and private organisations who are working to stimulate demand for low-carbon industrial materials. In collaboration with national governments, IDDI works to standardise carbon accounting standards, establish ambitious public and private sector procurement targets, incentivise investment into low-carbon product development and design industry guidelines.

Coordinated by UNIDO, the IDDI is co-led by the UK and India and current members include Canada, Germany, Japan, Saudi Arabia, Sweden, and United Arab Emirates (UAE), and the United States. The initiative brings together a strong coalition of related initiatives and organizations including the Mission Possible Platform, the Climate Group, the Leadership Group for the Industry Transition (LeadIT), and the World Economic Forum to tackle carbon intensive construction materials such as steel, cement and, cement.

Within the next three years IDDI expects to have encouraged a minimum of ten governments to make public procurement commitments for low-carbon steel and cement. An estimated 80 per cent of cement and 90 per cent of steel is produced in around ten key countries respectively. Therefore the adoption of green public procurement commitments — even in just a handful of these countries — will make a great impact in terms of greenhouse gas emission reduction.




Public procurement of steel and cement represents a very high share of domestic markets for such materials across most major economies. The Green Public Procurement Campaign is an effort by participating members to drive the global decarbonisation of heavy industries such as steel and concrete by creating a market demand for low- and near-zero carbon concrete and steel through public procurement commitments.

IDDI’s Green Public Procurement Pledge asks member governments to start (no later than 2030) requiring that steel, cement and concrete used in all public construction projects are low-emission – and that ‘signature projects’ use near-zero emission materials. It also includes targets to require (by 2025) the monitoring and disclosure of embodied carbon emissions of steel, cement and concrete in publicly-funded construction projects. (Embodied carbon is all the carbon emitted by producing a material throughout its lifecycle.) The aim is for net-zero emission steel, cement and concrete to be used in all public construction projects by 2050.

The pledge sends a clear message to steel, cement and concrete manufactures. It explicitly recognizes that low- and near-zero construction materials may cost more in the short-term, but governments will still buy these products for public works if they are made.

By 2025, IDDI expects to have enabled a minimum of ten governments to make green public procurement commitments to buy low or near-zero emission steel, cement, and concrete.

Additional Information

Making these programme goals a reality requires a number of complementary efforts and global outputs, which will be completed within a three year timeframe.

1. A standard environmental reporting mechanism for both the cement and steel industry, providing a consistent communication framework for organizational accountability.

2. A standard evaluation process and tools for project bids which incentivise and reward public work contractors on their commitment to source decarbonised building materials.

3. Consistent minimum standards for low-carbon steel and cement products to encourage best production and manufacturing practice.

4. Procurement guidelines for government agencies detailing how to set environmental project targets and incentivise contractors to source and use low-carbon steel and cement products.

5. The launch of a free or low-cost certification service, enabling cement and steel producers to demonstrate their commitment to the decarbonised production of steel and cement while simultaneously accelerating global demand for certified low-carbon steel and cement.

6. Publicly available data, research and tools for industry and governments to set targets, establish industry wide definitions of key sustainable products, improve production processes and benchmark best practice between organizations and industries.

7. Industrial deep decarbonisation training and knowledge sharing to ensure that all cement and steel manufacturers have access to the information required to participate in the global race to net zero.

8. A global 2050 vision for the decarbonisation of the steel and cement industries with ambitious targets informed by collective stakeholder input.
