Climate Change


A growing number of IZA member companies have committed to climate change policies to reach net-zero Scope 1 and 2 GHG emissions by 2050. And an increasing number are now working on Scope 3 targets as well.

To help facilitate this process, IZA established the Climate Change Task Force (CCTF) in 2021, engaging company representatives and experts worldwide at all levels of the zinc value chain. By bringing together producers, suppliers, and customers, the CCTF will help foster partnerships that enable the development of a de-carbonization strategy for the whole zinc sector. 

How the Zinc Industry Tracks Progress

There is a clear demand for “low carbon” and “green” products, highlighting the need for transparent and assured emissions reporting for making claims. While all IZA members have access to a full environmental profile for each asset through the global LCA, demands for carbon-specific assurance for sites and products have multiplied across the entire value chain.

The Zinc Carbon Footprint Guidance harmonizes data collection and reporting methods, while recognizing best practice for the industry’s unique structure, supply chains, raw materials, and down-stream uses.

  • Technical Guidance on Carbon Footprint Calculation and Reporting for Special High-Grade Zinc.
  • LME Approved Partner for voluntary reporting under LMEpassport.
  • Clear definitions and methods built from ISO and GHG Protocol norms.

Member Highlights

Hindustan Zinc Limited.

Hindustan Zinc Limited (HZL) has committed to Net Zero by 2050 in alignment with the Science-Based Targets Initiative (SBTi).  In addition, HZL has committed to investing $1 billion in climate change actions over the next five years.  Practical GHG reduction measures include the use of Battery Electric Vehicle (BEV) in underground mining and the expression of Interest (EOI) for the Supply of 300 MW of Renewable Energy.
