AUCKLAND, Today: IAB New Zealand has launched a new Sustainability Whitepaper, offering a hands-on guide to help agencies, publishers, and advertisers make digital advertising more sustainable and future-ready.

The 14-page guide gives practical advice on cutting emissions, building trust, and unlocking social and economic benefits while staying effective and relevant in a fast-changing market.

Created by the IAB New Zealand Sustainability Working Group, the paper outlines actionable steps and frameworks to reduce the environmental footprint of digital campaigns while improving efficiency. It also includes key definitions, Q&As, and extra resources for deeper learning.

Key recommendations include:

  • Optimising the supply chain by reducing intermediaries and streamlining supply paths
  • Designing lighter creative assets to lower energy use
  • Adopting green hosting with renewable-powered servers
  • Using smart delivery techniques such as lazy loading to cut wasted data transfers
  • Measuring emissions
