The climate-related regulatory landscape continues to shift, with long-watched legislation in the EU, UK and California now starting to officially go into effect. From the rollout of the EU’s Green Claims Directive and CSRD to evolving standards in the UK and North America, the risks of non-compliance, both legal and reputational, have never been higher.
As we continue to navigate a fragmented regulatory environment requiring more visibility into emissions, including on critical on scope 3 emissions where marketing spend sits, all in the global advertising ecosystem need to understand the implications.
Ad Net Zero is hosting a cross-market expert panel that will move beyond headlines and offer practical insights from sustainability experts into what brands, agencies, and media owners must prepare for in the remainder of 2026, setting up for 2027.
