Do Good, Do Well | Bridging Climate‑Tech Innovation and Marketing Investment

Around the world, the blue economy, the set of industries and innovations linked to oceans and coasts, is emerging as a multi‑trillion‑dollar opportunity.  Yet investment into blue‑tech solutions remains a fraction of overall climate‑tech capital.  Recent analysis estimates that blue‑economy ventures attract only around seven per cent of climate‑tech capital and would need an additional US$ 175 billion per year to meet United Nations Sustainable Development Goal 14; Life Below Water (Janulis & Keller 2025).  At the same time, consumers are demanding more from business: 78 per cent of people believe brands should do more than make money and make a positive impact on society (Epperson 2023).

We want to show that bridging these two gaps creates an opportunity for brands, investors and technology innovators.  Through sponsoring deployments of blue‑tech solution, such as autonomous vessels that clean waterways or micro‑recycling systems that close the loop on waste,  companies can “do good” (create measurable environmental and social outcomes) while also “do well” (achieve marketing return on investment, employee engagement and long‑term brand differentiation). 

So, we’re introducing a new metric, ROII – Return on Investment and Impact.  A concept that expands on the traditional notion of ROI by combining financial return with measurable environmental and social benefit.

The formula is simple:

Wild Places, Storytelling and ROII

The problems that plague our oceans are often out of sight and out of mind.  Beneath the surface lies one of our greatest opportunities for impact, yet we seldom think about it.  Whales were once just anonymous creatures until Greenpeace gave them names and stories people could relate to.  In a similar way, the blue economy needs storytellers, people who can bring ocean innovation into public consciousness and inspire meaningful action.

Across the world, scientists, researchers and innovators are reimagining how we produce energy, reduce pollution and farm the sea sustainably. We want to connect these innovators with those who want to be recognised as enablers of this final frontier of sustainability.  The ocean covers more than 70 per cent of the planet; responsibly harnessing even a fraction of its potential, through blue technology, renewable energy and seaweed‑based solutions, could help mitigate climate change and reshape our relationship with nature.  Yet the marketing power behind ocean innovation remains largely untapped.

Our mission is to deploy creative marketing and sponsorship models that drive awareness and real‑world impact, connecting founders with corporates, corporates with innovators, crowdfunders with projects and everyone in between.  We see this as a defining moment for the blue economy, a chance to build momentum for people and projects driving ocean‑positive change.

In doing so, we propose a new way of thinking about return on investment.  Traditional metrics focus solely on money; they capture financial performance but not the ripple effects of real‑world change.  ROII – Return on Investment and Impact challenges businesses and investors to look beyond short‑term gain and evaluate how their capital catalyses tangible environmental and social benefit.  This approach blends data, storytelling and strategic marketing to make these returns visible and measurable.

1 The Blue Economy Opportunity and Gap

The blue economy encompasses marine transport, fisheries and aquaculture, coastal tourism, renewable ocean energy and the myriad industries linked to ocean health and coastal communities. Despite its scale, funding remains scarce. Venture capital flowing into blue‑tech grew rapidly over the past five years but still represents only about 7 % of total climate‑tech capital, and analysts estimate a US$175 billion annual financing gap for ocean innovation, infrastructure and conservation (Janulis & Keller 2025). Even promising ventures struggle to progress beyond seed stage, and investors often seek more success stories and exits to justify committing larger pools of capital.

In emerging markets, the challenges are compounded. Many coastal communities lack infrastructure to support high‑tech solutions, and small‑scale fishers face a daily trade‑off between immediate income and long‑term sustainability. Against this backdrop, public investment and philanthropy alone cannot meet the need. Private capital, especially marketing and sponsorship budgets, could play an important role.

1.1 Why the Financing Gap Persists

1. Perceived risk and limited exits.  Blue‑tech ventures interact with living ecosystems and regulatory frameworks that evolve slowly.  Venture funds often view them as riskier than software or energy investments and note the limited number of high‑profile exits to date.

2. Infrastructure and market challenges.  Solutions must adapt to local conditions, from port logistics in Lagos to harbour operations in New York.  Start‑ups often require patient capital and blended finance to build proof points.

3. Lack of awareness.  Many investors and corporate sponsors are not familiar with the breadth of opportunities in ocean innovation or the financing mechanisms available.  This gap represents an opportunity for storytelling and education.

   
   

2 Marketing and Climate Tech

While blue‑tech innovators search for capital, global marketing budgets continue to grow.  Cause‑marketing research shows that 78% of consumers think brands should have a positive social impact (Epperson 2023).  When companies align with causes that resonate with their mission, they build deeper customer relationships, stronger employee engagement and more resilient brands.  Conversely, neglecting cause‑marketing risks reputational damage and missed connections with conscious consumers (Epperson 2023).

This creates our hypothesis: reallocate a portion of marketing budgets to sponsor climate‑tech deployments.  Sponsorship yields tangible, measurable outcomes, such as tonnes of waste removed from waterways or number of local jobs created, alongside visibility and brand lift.  It also provides a narrative that transcends product features and speaks to purpose.

3 The Sponsored Deployment Model

TSC has been piloting a sponsored deployment model through its work with RanMarine Technology and other partners.  The concept is straightforward:

• Innovators supply technology. RanMarine’s zero‑emission autonomous surface vessels (WasteShark, MegaShark, CyanoShark) remove floating waste, plastics and biomass while collecting water‑quality data.  Partners like Ocean Plastic Technologies (OPT) provide Micro Recycling Pods (MRPs) that sort and process collected material into local circular streams.  Together these tools create a closed‑loop solution.

• Sponsors fund deployments. Municipalities, port operators, developers and brands provide funding in exchange for co‑branding and storytelling opportunities.  They may support one vessel for a single harbour or a fleet across multiple sites.

• Local partners operate and train. Community operators manage day‑to‑day operations and receive workforce training, creating jobs and building local capacity.

• Data is shared. Environmental impact (waste volume, geotagged water‑quality data) is tracked and reported alongside socio‑economic indicators.  This transparency supports sponsors’ ESG reporting and builds trust.

3.1 RanMarine Context

RanMarine is a cleantech company specialising in autonomous surface vessels for waterway cleanup and environmental data collection.  Its WasteShark, MegaShark and CyanoShark platforms are commercially available and have attracted interest from municipalities and private operators.  For sponsors, partnering with an established supplier of ocean‑cleaning technology reduces implementation risk and increases confidence that deployments will deliver measurable results.  This section underscores that selecting credible, growth‑oriented innovators is critical to the success of the sponsored deployment model, regardless of how those companies are funded or listed.  Sponsors benefit from associating with trusted technology providers and gain early access to tools that can be scaled across multiple sites.

4 Case Studies: Lessons from Cause‑Aligned Marketing

4.1 Citibank and New York City’s Citi Bike

In 2013, New York City launched a large bike‑sharing programme.  Citi and MasterCard provided the financing, contributing roughly US$41 million for a five‑year partnership that delivered 10,000 Citi‑branded bicycles and 600 stations across Manhattan (Pilcher 2012).  The system required no public funding.  Bikes and docking stations were painted Citi blue, and the program’s name, Citi Bike, effectively turned the entire network into a moving billboard.

The marketing value was significant.  Thousands of bikes and kiosks gave the bank positive name awareness in a prime market, and because the bikes are human‑powered, the programme skirted city laws against advertising on transportation vehicles (Pilcher 2012).  Analysts estimated the cost at about US$2.20 per day per bicycle, making it one of the most cost‑effective outdoor advertising campaigns in the city (Pilcher 2012).  Beyond visibility, Citi demonstrated support for urban mobility and sustainability, reinforcing its brand as a civic partner.  The case shows how underwriting public infrastructure can deliver both social benefit and marketing ROI.

4.2 Leeds WasteShark – Community Crowdfunding and Sponsorship

An example of a RanMarine initiative in Leeds, where residents, local businesses and corporate sponsors rallied around a shared goal: to keep their waterways clean.  The Leeds WasteShark initiative began in 2024, when the Leeds Waterfront Group and partners introduced a remote‑controlled WasteShark, a zero‑emission aquatic drone capable of scooping up to 160 litres (50 kilograms) of waste per trip.  Operating on the Leeds waterfront, the drone removed over 4,000 litres of organic matter, plastics and other debris in its first year.

The programme faced an uncertain future when its initial funding expired.  Instead of letting the initiative fade, the community launched a crowdfunding campaign and secured match funding from businesses.  According to a 2025 report by Dedalus, more than 400 public donations and twelve local business sponsors raised over £45,000.  Corporate supporters included Dedalus, Vastint UK (Aire Park), Canal River Trust, Mustard Wharf, Royal Armouries, Fullers Foods and others.  This funding will not only keep the WasteShark operating for another year but will also add an extra day of cleaning each week.

Community engagement has been central to the project’s success.  Residents, the Leeds Civic Trust, Yorkshire Design Group, Biffa and other partners contributed expertise and outreach.  Paul Ellison, Chair of the Leeds Waterfront Group, captured the mood: “We’re blown away by the response to our Leeds WasteShark initiative.  WasteShark is unique to our city and it’s hugely gratifying to know that so many people share our desire to continue making a difference at a local level”.

The Leeds experience shows how crowdfunding and corporate sponsorship can sustain and expand blue‑tech deployments.  It demonstrates the power of local storytelling: a clear mission, a tangible technology and a community that wants to see their waterways restored.  Sponsors benefit by associating with a visible, positive project, while residents enjoy cleaner rivers and canals.  The initiative also lays the groundwork for future scale; with stable funding and data collection, Leeds can inspire other cities to replicate the model and measure ROII by tracking both financial contributions and environmental impact.

4.3 Aqua Libra and Canary Wharf

In March 2023 we helped the flavoured‑water brand Aqua Libra and the Canary Wharf Group bring London’s first WasteShark to Middle Dock. The battery‑powered robot can roam up to five kilometres and collect up to 500 kilograms of floating waste per day. It runs quietly without emitting noise, light or carbon , collecting water‑quality data as it patrols.

This partnership was designed to bring Aqua Libra’s mission to reduce single‑use plastic to life on the water. We guided the project from concept to launch, ensuring it aligned with the brand’s values. Media coverage amplified the story: Waste360 reported that the Aqua Libra‑branded robot could collect the equivalent of 22 700 plastic bottles per day and quoted Britvic spokesperson Steve Potts describing how the deployment supports their vision for eliminating packaging waste . Smart Cities World likewise highlighted that the WasteShark can navigate up to 5 km and gather 500 kg of debris per day. Even cultural outlets picked up on the novelty; one cartoon in The New Yorker portrayed the WasteShark as a “trash‑eating sea monster,” underscoring its public appeal.

Sponsoring a single piece of technology and branding it with its name, Aqua Libra secured widespread press coverage, meaningful environmental data and a memorable story that reinforces its sustainability narrative. For TSC, the project proved that a well‑executed sponsored deployment can generate real impact, high visibility and lasting goodwill.

5 Measuring ROI and Impact

To make the case to marketing directors and investors, sponsored deployments must deliver verifiable results.  A robust evaluation framework should track:

• Environmental outcomes: volume of debris removed; number of “clean days” in a harbour; water‑quality improvements; percentage of waste routed into circular streams.

• Socio‑economic outcomes: number of local jobs created; hours of workforce training delivered; community engagement metrics.

• Marketing metrics: media impressions; social‑media engagement; brand sentiment surveys; employee morale; customer acquisition or retention.

• Financial metrics: cost per environmental outcome unit (e.g., cost per tonne of waste removed); comparison of sponsorship cost to equivalent advertising spend (Citi’s US$2.20 per bike per day provides a useful benchmark (Pilcher 2012)).

Integrating these metrics into sponsorship agreements, brands move beyond anecdotal stories to demonstrate tangible return on investment.

6 Implementation Guidance

6.1 For Brands and Sponsors

1. Align with mission and audience. Identify environmental or social issues that resonate with your brand values and customer base.  Authenticity is critical; customers can detect tokenism (Epperson 2023).

2. Select credible partners. Work with technology providers and non‑profit organisations with established track records.  Conduct due diligence on their environmental claims and data practices.

3. Co‑design the deployment. Define the scope (e.g., number of vessels, deployment sites), branding, data sharing and reporting cadence.  Involve local communities early to ensure relevance and buy‑in.

4. Allocate marketing and operations budget. Treat the sponsorship as a long‑term investment rather than a one‑off ad spend.  Dedicate staff or agencies to manage communications and measure impact.

5. Communicate transparently. Share successes and challenges, data and stories.  Highlight progress toward environmental and social goals; avoid over‑claiming impact.

   
   

6.2 For Blue‑Tech Innovators

1. Demonstrate technological readiness. Ensure the solution is deployment‑ready and can operate reliably in local conditions.

2. Develop sponsorship packages. Prepare tiered proposals outlining deployment costs, expected environmental outcomes, branding opportunities and reporting metrics.

3. Build data infrastructure. Provide sponsors with real‑time dashboards and periodic reports aligned with SDGs and ESG frameworks.

4. Engage communities. Recruit and train local operators; design programmes that create jobs and build capacity.

5. Help innovators scale - get investor ready. Provide concise business‑planning, governance and fundraising support to help innovators attract investors.

6. Use small‑ticket investment to catalyse scale. TSC invests small amounts early, while the sponsored‑deployment model lets ventures grow without major equity dilution.

   
   

6.3 For Investors

1. Consider blended finance. Equity investments paired with sponsored‑deployment revenue streams can de‑risk ventures and accelerate scale.

2. Evaluate long‑term brand value. Factor reputational uplift and stakeholder relationships into investment decisions.

3. Assess scale potential. Prioritise companies with a clear roadmap for growth and the capacity to expand operations.  Organisations that are actively scaling their technology or entering new markets will have both the incentive and capability to support sponsored deployments.

The gap between climate‑tech innovation and marketing investment is both a challenge and an opportunity. The blue economy needs new sources of capital and attention. Consumers are demanding purpose from brands, and purpose‑driven companies are outperforming their peers. By sponsoring deployments of blue‑tech solutions, brands can create measurable environmental and socio‑economic impact while achieving meaningful marketing returns.

The experiences of Citi Bike; where a US$41 million sponsorship produced city‑wide brand visibility (Pilcher 2012), and the Leeds WasteShark, where community crowdfunding and corporate sponsors raised over £45,000 to keep a water‑cleaning drone in operation, show that doing good can indeed mean doing well.  These examples demonstrate how cause‑aligned marketing can deliver both public benefit and brand value. TSC’s pilot projects show that the model can be adapted to emerging markets and integrated into government initiatives.  As the climate crisis intensifies, aligning marketing budgets with planet‑positive action is not just good citizenship; it is smart business.
