Exploring the use of market instruments to account for the procurement of low-carbon ammonia, biomethane and low-carbon steel.
Overview
Co-developed by WBCSD and the Carbon Trust, these scenario-based case studies explore hypothetical examples across chemical manufacturing, food and agriculture, and the automotive sector.
Scenario-based case study: Low-carbon ammonia
This case study explores how market instruments can account for low-carbon ammonia used in fertiliser across complex food and agriculture supply chains.
It uses a worked example to compare book-and-claim and mass balance approaches, highlighting when each may be appropriate, how they affect emissions reporting, and what businesses need to consider to make credible claims as standards evolve.
Scenario-based case study: Low-carbon ammonia
Scenario-based case study: Low-carbon fuels
This case study explores how market instruments can account for biomethane used in hydrogen peroxide production within chemical manufacturing.
It uses a worked example to compare mass balance and book-and-claim approaches, showing how each affects emissions reporting and how businesses can make credible claims as standards evolve.
Scenario-based case study: Low-carbon fuels
Scenario-based case study: Low-carbon steel
This case study explores how market instruments can account for low-carbon steel in automotive supply chains where lower- and higher-carbon steel cannot be physically separated.
It uses a worked example to compare mass balance and book-and-claim approaches, showing how they affect emissions reporting and can inform supplier engagement and chain-of-custody decisions.
