The cleantech public relations market has matured considerably. A defined group of agencies has moved beyond surface-level sector positioning to develop the journalist relationships, analyst access, and substantive case studies that distinguish established practices from generalists adding cleantech as an additional service line.
For B2B climate tech and renewable energy companies, the practical question is no longer whether a sector specialist matters, but which specialists have the track record and capabilities to support specific business outcomes. This guide identifies five agencies that meet that standard. Each has verifiable cleantech case studies, named clients, and a sustained pattern of work across the sector’s distinct audiences, including trade reporters, sector analysts, infrastructure investors, utility procurement teams, and policy stakeholders.
The Five Agencies
- twentytwo & brand (United States): Full-service cleantech and renewable energy marketing communications
- Sterling Communications (Silicon Valley, CA): Cleantech public relations and media training for technology-driven climate companies
- Inkhouse (Boston, MA): Climate tech and energy public relations for innovators across the cleantech spectrum
- Channel V Media (New York, NY): Climate technology public relations for market entry and category positioning
- (W)right On Communications (San Diego, CA): Integrated communications for cleantech, energy, and B2B technology companies
1. twentytwo & brand

Why It Made the List
twentytwo & brand operates exclusively within the cleantech, climate tech, and energy transition space. The agency provides full-service communications across branding, public relations, digital marketing, advertising, social media, web design, and lead generation. This integration of capabilities within a single team is uncommon in cleantech communications, where most agencies address one or two functional areas rather than the complete marketing function. Companies looking for a dedicated PR agency for cleantech companies will find that twentytwo & brand’s sector-exclusive focus sets it apart from generalists adding climate as a secondary practice.
Cleantech Practice Focus
The agency was built specifically for climate and energy companies with lean marketing teams operating under real pressure. Most agencies in this space either do public relations or creative work. twentytwo & brand does both, and deliberately integrates storytelling, communications strategy, and design because the team recognizes that this integration is necessary for complex technologies to be understood and evaluated.
Notable Work
The agency has reported 651 percent revenue growth between 2021 and 2023 and currently serves a client base of more than 100 cleantech brands. For FranklinWH, twentytwo & brand delivered a complete North American market entry program within four weeks ahead of a conference deadline. For Castillo Engineering, the agency’s branding and media relations work supported the company’s first 100 MW+ utility-scale contract.

The Climate Technology Division has since added clients including Meteomatics, a weather intelligence company, further strengthening its position among agencies serving the climate technology sector.

When to Hire This Agency
B2B climate tech and renewable energy companies operating on the West Coast of the United States or in cross-border North American markets that require integrated communications support, including event execution, video production, and community outreach alongside earned media work.
Selection Methodology
This ranking draws on publicly available sources, including agency websites, verifiable case studies, directory profiles, client review platforms, and trade publication coverage. The selection criteria were as follows.
- Verifiable cleantech case studies. Every agency on the list has published case studies with named clients, documented results, and identifiable media placements. Agencies that described cleantech capability in general marketing terms without specific evidence were excluded.
- Sustained sector presence. The agencies included show consistent cleantech work over multiple years rather than isolated projects. This indicates established media relationships and ongoing client retention within the sector.
- Differentiated positioning. Each agency on the list serves a distinct type of B2B climate tech engagement, ensuring the guide is useful for companies with different requirements. Agencies with substantially overlapping positioning were narrowed to a single representative.
- Independent confirmation. Reported results were cross-referenced with external sources, including trade publication coverage and press release confirmation, where possible.
Considerations for Different Company Stages
The right agency for a B2B climate tech company depends substantially on the company’s stage and the specific business outcomes the communications function is expected to produce.
- Pre-commercial and seed-stage companies typically need agencies that can support category-creation communications, founder visibility, and the early stages of investor narrative development. Channel V Media’s narrative-first approach and Sterling Communications’ work with category-leading clients are well-aligned to this stage.
- Series A and Series B companies typically need agencies that can produce the volume and quality of earned media necessary to support fundraising, partnership development, and early enterprise pipeline. twentytwo & brand’s full-service capability and Sterling Communications’ track record with milestone announcement campaigns are positioned for this stage.
- Growth-stage and pre-IPO companies typically need agencies with the depth and footprint to support multi-stakeholder communications across investor, customer, utility, policy, and recruiting audiences. Inkhouse’s national footprint and (W)right On Communications’ integrated capability across earned media, event execution, and community outreach are positioned for this stage.
- International companies entering the United States typically need agencies with specific market-entry experience and the relationships necessary to establish category visibility in conversations where the company is not yet known. Channel V Media’s documented work in this area is particularly relevant.
Questions to Ask Before Hiring
Before committing to an engagement, the following questions are worth asking any cleantech public relations agency under consideration.
- Which cleantech clients has the agency worked with in the past 24 months, and what specific outcomes did each engagement produce? Agencies with genuine sector experience will be able to answer with specific company names, campaign objectives, and documented results, including media placements and quantitative outcomes.
- Which cleantech trade publications has the agency placed stories in within the past six months, and who were the specific contacts? Agencies with active media relationships will be able to name reporters by name and describe the relationships in detail.
- How does the agency measure success? Agencies with strong cleantech practices track outcomes that include earned media placement quality and tier, share of voice against named competitors, message pull-through in published coverage, and executive visibility in the publications investors and buyers read.
- What is the scope of the proposed retainer, and what activities fall outside that scope? Public relations retainers vary considerably. Confirming inclusions and exclusions before signing prevents disputes later in the engagement.
- Who will run the account on a day-to-day basis? The team presenting in the pitch is often not the team that delivers the work. Companies should confirm the specific people who will operate the account and their direct experience in cleantech.
FAQs
What does a cleantech PR agency do?
A cleantech public relations agency manages earned media, thought leadership, analyst relations, and strategic communications for companies in clean energy, climate tech, and renewable energy. The work supports specific business outcomes such as fundraising, enterprise sales cycles, partnership development, recruiting, and market entry.
How is cleantech PR different from general B2B PR?
The audiences are more specialized. Cleantech communications need to reach trade reporters, sector analysts, infrastructure investors, utility procurement teams, and policy stakeholders, often in parallel. The technical claims in press materials are reviewed by readers who can evaluate them, which raises the bar for accuracy and substantiation.
How much does a cleantech PR agency cost?
Pricing varies based on scope and structure. Retainer-based engagements with established cleantech public relations firms typically start in the mid-four-figure range per month and scale into five figures for full-service programs. Project-based engagements around specific announcements are available with some agencies.
When should a B2B climate tech company hire a PR agency?
The most common timing is in the run-up to a funding round, a product launch, a market entry, or a partnership announcement. Public relations is also used as an ongoing function for companies in active enterprise sales cycles, where third-party coverage supports buyer confidence and shortens evaluation timelines.
How long does it take to see results from a cleantech PR engagement?
Initial earned media placement typically begins within the first 60 to 90 days of an engagement, assuming the agency has existing sector relationships. Larger feature coverage, analyst engagement, and conference speaking opportunities generally develop over a longer timeline of 6 to 12 months.
Should a B2B climate tech company hire a generalist or specialist agency?
Specialist agencies typically reach productive output faster because they do not require a ramp-up period to develop sector understanding and media relationships. For companies operating under tight fundraising or market entry timelines, that difference is often the deciding factor. Generalist agencies can produce strong work in cleantech, but the timeline to that output is generally longer.
Can a single PR agency support both United States and international communications?
Some agencies operate across multiple geographies directly. Others partner with regional agencies to support international markets. Companies with multi-market communications needs should confirm how the agency handles international work before signing an agreement.
Conclusion
Choosing the right clean tech PR agency in 2026 is not only about getting media coverage. It is about finding a partner that understands climate innovation, investor expectations, policy shifts, and the fast-moving clean energy market.
The best agencies do more than write press releases. They help clean tech brands build trust, explain complex solutions clearly, reach the right audiences, and stay visible in a competitive space. Whether your company works in renewable energy, EV technology, carbon capture, energy storage, climate software, or sustainable infrastructure, the right PR team can make your message stronger and easier to believe.
As clean tech continues to grow, communication will matter more than ever. Brands that can tell their story clearly will have a better chance of attracting customers, investors, partners, and public support.
So before choosing an agency, look at their industry experience, media relationships, storytelling style, and ability to understand technical topics. A good clean tech PR agency should not just promote your brand. It should help people understand why your work matters.
