Merger branding in climate tech: 5 proven post-acquisition strategies that work
Branding
5/9/2025
Climate tech companies are reshaping the future. As the sector matures, mergers and acquisitions (M&A) are becoming more common, offering a path to scale, accelerate innovation, and enter new markets. However, when two companies merge, their existing brands, stories, and cultures also come together. How you handle branding during a merger or acquisition can significantly impact the success of the deal.
Branding after an acquisition is not simply about updating logos or merging websites. It's a strategic tool to communicate vision, build trust, align internal teams, and retain loyal users. In the sustainability-driven world of climate tech, where purpose and transparency are non-negotiable, your post-merger brand must reflect the values and ambitions of the acquired company.
This guide explores the best approaches to branding after a merger or acquisition in climate tech, from aligning identities to leveraging brand assets, crafting unified brand messaging and avoiding the pitfalls that often follow M&A transitions.
Why branding matters in climate tech mergers
M&A deals are rarely smooth, especially in purpose-driven industries such as clean energy, carbon capture, or renewable technology. Branding helps ensure brand consistency:
1. Drive alignment in mission and sustainability goals
In climate tech, mission alignment is as important as financial synergy. A strong post-merger brand brings clarity to:
• Your environmental mission
• Shared long-term goals
• Commitments to innovation and sustainability
2. Build stakeholder trust
From employees to investors and clients, stakeholders want to see a clear path forward. Consistent branding post-merger among multiple brands:
• Communicates stability
• Signals professionalism and planning
• Reinforces brand reputation
3. Retain brand equity
If the acquired brand has goodwill in the market, a rebranding strategy must be strategic, not reactive. A thoughtful merger branding process can preserve:
• Existing client loyalty
• Brand recognition
• Value associated with certifications, partnerships, or awards
Common challenges in merger branding
M&A branding can be complex and emotional. The top hurdles include:
1. Culture clashes between merging companies
Climate tech startups often have distinct cultures, from founder-led innovation hubs to enterprise-scale clean energy firms. Misaligned values and working styles can lead to brand dilution.
2. Conflicting brand values
If one company is community-driven while the other focuses on enterprise tech, you will need to reconcile and clarify values without alienating either client base.
3. Visual identity inconsistency
Merging two brands with completely different logos, typefaces, and design systems can result in a confusing and inconsistent look if not managed well.
4. Risk of brand confusion
Failing to communicate clearly can leave clients wondering:
• Who is the new company?
• Are products or services changing?
• Is the merger temporary or permanent?
Key steps for rebranding after acquisition
An intentional, phased rebrand ensures a smooth transition.
1. Conduct a comprehensive brand audit
Start with internal and external research to assess:
• Brand recognition and recall
• Stakeholder sentiment
• Competitive positioning
• Strengths and weaknesses of each brand
2. Choose the right brand architecture
There are several brand architecture models:
• Branded house: One master brand with unified sub-brands (e.g. Alphabet/Google)
• House of brands: Each brand operates independently (e.g. Unilever)
• Endorsed brand: A mix (e.g. Marriott Courtyard)
Climate tech mergers often favour branded houses to streamline identity and mission.
3. Develop a new naming, messaging, and brand voice
The post-merger name and brand voice should reflect:
• Climate-focused ambitions
• Inclusivity of both brands
• Market relevance
• Domain availability
4. Build brand guidelines and toolkits
Include:
• Logo usage
• Typography
• Colour systems (with eco-conscious symbolism)
• Tone of voice
• Templates for presentations, email, social, etc.
5. Craft a clear stakeholder communication plan
Prepare messaging for:
• Internal teams
• Investors and board members
• Existing clients
• Press and media
• Partners and collaborators
How to retain and reimagine brand equity
Brand equity is fragile during M&A.
1. Recognise the acquired brand’s legacy
Honour past achievements through storytelling, acknowledgements, and internal communications.
2. Integrate legacy elements into the new brand
Examples:
• Keeping colour schemes
• Retaining visual cues in the new logo
• Preserving signature slogans or campaigns
3. Highlight differentiation in the marketplace
Use the rebrand as part of your business strategy to clarify what sets the merged company apart: is it the technological edge, broader solutions, or sustainability leadership?
Building a unified brand identity post-acquisition
Your new brand should be more than the sum of its parts.
1. Create a shared vision for the merged entity
Define and communicate:
• Brand mission
• Vision for climate impact
• Company values
• Strategic goals
2. Use storytelling to humanise transitions
Talk about:
• Founders’ perspectives
• Employee journeys
• Community impact
This fosters empathy and connection during change.
3. Rebuild emotional connection with clients
Use marketing materials and social media to share:
• The "why" behind the merger
• How it benefits potential and existing clients
• Commitments to sustainability and service
Post-merger integration strategy for climate tech brands
1. Internal brand onboarding
Train your team on:
• New messaging
• Design assets
• Client communications
• Behavioural expectations
2. Align internal teams around the new identity
Host:
• Brand training sessions
• Leadership roundtables
• Team Q&As
3. Launch a strategic brand rollout externally
Plan:
• Email and press announcements
• Website updates
• Social campaigns
• Paid media
• Partner communications
Cultural integration and internal brand alignment
Branding isn’t just external. It lives in your team culture.
1. Address cultural differences proactively
Don’t assume alignment. Instead:
• Facilitate culture workshops
• Survey employees regularly
• Create cross-functional project teams
2. Use branding to manage change
A clear brand vision helps manage:
• Fear of change
• Role uncertainty
• Resistance to new systems
3. Empower leaders to carry the brand forward
Train managers to:
• Communicate brand values
• Model behaviours
• Reinforce messages
Avoiding common post-merger branding mistakes
1. Rushing the rebrand
Take time to plan. Poorly executed rebrands can confuse clients and damage a company's reputation.
2. Ignoring employee perspectives
Employees are your brand ambassadors. Involve them early through surveys, ideation sessions, and testing.
3. Underinvesting in communication
Avoid gaps between leadership decisions and team execution by:
• Holding regular updates
• Sharing roadmaps
• Repeating key messages consistently
The role of user insights in post-merger branding
1. Conducting sentiment research
Before launching a rebrand, assess how current clients feel about:
• Each brand’s reputation
• Product or service value
• Emotional connection to the brand
• Concerns about the merger
Use surveys, interviews, and social listening tools.
2. Understanding evolving client expectations
Post-merger clients may expect:
• Expanded product lines
• Better service delivery
• A more coherent user experience
• Stronger sustainability commitments
Use these insights to shape your messaging, product roadmap, and service models.
3. Informing brand repositioning decisions
Let client feedback influence:
• Brand personality and voice
• Product naming conventions
• Visual elements
• Key marketing messages
This data-led approach prevents internal bias from dominating branding decisions.
Examples of successful climate tech merger branding
1. Case Study: Schneider Electric + L&T Technology Services
After acquiring a stake in L&T Tech, Schneider Electric co-branded strategic sustainability offerings while allowing L&T Tech to maintain its engineering-first brand identity. This hybrid branding model allowed both companies to retain credibility in their respective markets.
Key takeaway: Retaining legacy brand equity builds trust during early-stage integration.
2. Case Study: Xpansiv + APX
Xpansiv, a carbon market infrastructure provider, merged with APX, a trusted environmental registry platform. Their unified brand story focused on enhancing transparency and scalability in global carbon markets, presenting a bold yet credible image.
Key takeaway: Use the merger narrative to elevate your market position and sustainability impact.
3. Case Study: Engie + Ecova
When French energy giant Engie acquired Ecova, a US-based energy management firm, the two merged under the Engie Insight brand, highlighting both global reach and local energy intelligence.
Key takeaway: A new identity that bridges global influence and local expertise can enhance market relevance.
Future-proofing your brand after a merger
Sustainability tech branding is adaptive branding.
1. Create agile brand architecture
Design flexible systems that accommodate:
• Future acquisitions
• Sub-brands
• Co-branded offerings
• Service-line expansions
2. Monitor brand performance consistently
Use KPIs such as:
• Brand awareness
• Share of voice
• Client retention
• Sentiment analysis
• Market share changes
Use platforms like Google Analytics, Brandwatch, or Net Promoter Score (NPS) surveys.
3. Prepare the brand for entry into new markets
Post-merger expansion often includes:
• Launching in new geographies
• Targeting new verticals
• Scaling client acquisition
Ensure the brand is culturally adaptable, linguistically appropriate, and regionally relevant.
