Y'all really don't read the articles. The UN already has reports on greenwashing woth pretty solid definitions and recommendations. The report was linked in the article.

Excerpt from the linked UN report:

Our report also specifically addresses the core concerns raised by citizens, consumers, environmentalists and investors around the use of net zero pledges that make greenwashing possible. Our recommendations are clear that:

• Non‑state actors cannot claim to be net zero while continuing to build or invest in new fossil fuel supply. Coal, oil and gas account for over 75% of global greenhouse gas emissions. net zero is entirely incompatible with continued investment in fossil fuels. Similarly, deforestation and other environmentally destructive activities are disqualifying.

• Non-state actors cannot focus on reducing the intensity of their emissions rather than their absolute emissions or tackling only a part of their emissions rather than their full value chain (scopes 1, 2 and 3).

These recommendations explicitly cover the ad campaign discussed in OP's article, as well as many other greenwashing ad campaigns.
