Sustainability & Green Tech PR Agency | Words+Pixels

Green tech has a trust problem

Being green is no longer enough. Brands have to prove it.

With sustainability claims everywhere, consumers are becoming increasingly sceptical of what green, eco-friendly and sustainable actually mean. In fact, the UK’s Competition and Markets Authority found that 40% of green claims made online could be misleading.

That creates a challenge for brands genuinely driving change: how do you make people believe you?

That’s where PR matters. Credible coverage, research and thought leadership help brands cut through greenwashing, build trust and stand out.

FAQs: Green Tech PR Agency

1. What does a green tech PR agency do?

A green tech PR agency helps sustainability and environmental technology companies build awareness, trust and authority through media relations, thought leadership, creative campaigns and digital PR.

2. How is green tech PR different from consumer or tech PR?

Green claims face more scrutiny. Every story needs credible evidence, data or expert backing, such as like UCL's Professor Mark Maslin on Back Market's Last Shot Gallery, not just a strong marketing message.

3. What's the difference between green tech, cleantech and climate tech?

Green tech is the broadest term, covering technology designed to reduce environmental impact. Cleantech typically focuses on cleaner use of energy and resources, while climate tech focuses specifically on technologies addressing or adapting to climate change.

4. How do you avoid greenwashing accusations?

Start with evidence, not the marketing line. Our campaigns are built around credible research, real impact and stories that can stand up to scrutiny.

5. Big campaign moment, or always-on PR?

Both. A campaign like Back Market's gallery can create an immediate spike in attention, while an always-on press office like OakTree Power or Revalue builds authority over time.

6. What results should I expect from green tech PR?

Creative campaigns can generate fast bursts of media attention, while sustained PR builds visibility, credibility and authority over months.

7. Do I need a research angle to get coverage?

It helps. Original data, credible research and expert partnerships give journalists something stronger than brand opinion alone.

8. Can you help with a green tech funding announcement or product launch?

Yes -brief us early so we can shape the story, messaging and media strategy before the news lands.
