The Green Tightrope: How sustainability ads walk the line between scrutiny and trust

In today’s advertising landscape, sustainability has become the lingua franca of purpose-driven brands. But as brands drape themselves in green, the glare of scrutiny has grown equally intense. What began as a language of purpose now risks turning into a test of credibility, and creative agencies find themselves walking a fragile tightrope between impact and impression, purpose and perception.

Burson report 2025 reveals Indian consumers prioritize real-world impact, transparent communication, and grassroots progress in the nation’s evolving sustainability agenda...which has been directly linked to their awareness about the Green-washing of impact reports.

In recent years, even campaigns that earned global acclaim have not escaped suspicion. At Cannes Lions 2025, several sustainability-themed entries were quietly questioned in industry circles for overstating their measurable results.

Meanwhile, the Advertising Standards Council of India (ASCI) and Central Consumer Protection Authority’s updated guidelines have made clear that vague terms like “eco-friendly” or “100% sustainable” cannot be used without verifiable evidence, and mis‐claims may now expose brands to penalties under Indian consumer protection law.

The sentiment is clear; the world is tired of slogans that sound good but prove little.

Beyond the Visuals

For Aalap Desai, Chief Creative Officer and Co-Founder at Tgthr, the seduction of a powerful idea is where most sustainability narratives risk slipping.

“When we have a great idea, it is exciting to overlook details that should be in place,” he says. “Excitement does that. It’s part of the magic. The trick, according to me, is to not get seduced by it and take a step back and ensure that due diligence is done.”

Desai’s point resonates at a time when the rush to look responsible has occasionally outpaced the responsibility itself. “Once that’s done,” he adds, “every idea can be in the space it is supposed to be.”

The Proof Before the Story

Krishna Iyer, Director of Marketing at MullenLowe Lintas Group, calls sustainability “not a creative trend, but a test of credibility.”

“As consumers become more discerning,” he says, “brands can no longer rely on evocative imagery or emotional storytelling alone; every sustainability narrative must be anchored in measurable action.”

Iyer explains that at Lintas, the story follows the substance. “We ask a simple question: what change has the brand truly enabled, and how can we quantify it? Before a campaign idea takes shape, the proof must exist.”

His argument is mirrored by what’s happening globally. The Changing Markets Foundation’s 2023 report called such language “a systemic greenwash of everyday products.”

For agencies, the line between creative interpretation and factual overreach has never been thinner.

Checks, Balances, and the Fear of ‘Impact Washing’

The fear of being caught in what the industry now terms “impact washing”, the inflation of small actions into large environmental claims, has forced agencies to rethink their internal systems of validation.

Desai recommends a collaborative approach: “Talk to agencies and organisations that specialise on that. In my experience they are always open to discuss and help. If you connect with the right people, the probability of you going wrong goes down.”

Manika Juneja, Managing Partner at Dentsu Creative Isobar, agrees that the process has to be rooted in transparency from the first meeting. “Bringing every stakeholder to the table right from the start makes all the difference,” she says. “It helps balance ambition with accountability. If creativity or storytelling drifts a little too far, these early conversations bring it gently back on track.”

Her emphasis on collective honesty reflects a shift across agencies, many of which now bring sustainability experts into creative brainstorms, a move that was once considered unnecessary.

When Awards Blur the Message

The Cannes stage remains a tempting goalpost for the industry. But with heightened scrutiny, trophies have begun to carry an ethical fine print.

“When you just concentrate on the award, you lose focus on the cause,” says Desai. “That’s what makes it irresponsible.”

The Power of Consistency

Juneja argues that authenticity doesn’t demand spectacle. “Today’s consumers respond to small, meaningful acts more than grand statements,” she says. “For us, authenticity comes from evolution, not reinvention. When storytelling stays simple, relatable, and rooted in truth, and evolves consistently over time, that’s how trust is built quietly, through work that feels human, not performative.”

A Question of Trust

What unites all three creative leads is the recognition that sustainability storytelling is no longer about language or imagery, but about accountability. The public is reading between the lines, regulators are reading the fine print, and juries are reading the data sheets.

Sustainability, as Iyer puts it, “is not a campaign, it’s a contract.” And for the advertising industry, the contract is now being rewritten - clause by clause, claim by claim, under the sharp light of truth.
