1. Calling for Long-View Leadership with The Elders
Founded by Nelson Mandela, The Elders are a group of independent global leaders dedicated to advocating for peace, justice, human rights, and environmental sustainability. They recognize humanity’s most pressing threats—from climate change and pandemics to the misuse of AI and nuclear weapons. These challenges demand long-term solutions and proactive leadership.
What We Did: We partnered with The Elders to launch an open letter calling on world leaders to abandon short-term thinking and take a far-sighted approach to existential threats. Together, we created a robust campaign to amplify the open letter’s message, including developing a visually compelling hero animation, crafting stakeholder toolkits, activating paid advertising, and coordinating an extensive media outreach strategy. The campaign also leveraged influencer engagement to increase visibility, with renowned figures such as Cate Blanchett, Richard Branson, and Gordon Brown lending their voices to the cause.
Results & Impact: The campaign achieved significant global traction, securing 85 media placements across 19 countries and generating over 1.1 billion impressions. Social media efforts exceeded expectations, delivering 36.5 million impressions and engaging over 357,000 users online. More than 3,000 high-profile individuals signed the letter, including former UN Secretary-General Ban Ki-moon, actress Cate Blanchett, and former Prime Minister Gordon Brown. This powerful response underscored the urgency of adopting long-term leadership to address global crises.

2. Unlocking Land’s Potential with Gigaparks and NatPower UK
With over 25 years’ of experience and renewable energy projects in 20 countries, NatPower wanted to launch its new UK arm with a bang in early 2024. Their ambitious plan is to revolutionise the UK renewable energy landscape, including constructing several “Gigaparks” providing 60 gigawatt hours of battery storage, supplemented by solar and wind projects in the pipeline. To achieve these goals, NatPower sought partnerships with landowners to repurpose underutilised land for sustainable energy generation. This initiative promises to unlock the potential of rural areas while driving the UK closer to its net-zero targets.
What We Did: We supported NatPower UK’s launch by crafting a campaign that resonated with landowners and stakeholders. We created a cinematic hero film and a suite of compelling visual assets to capture online attention. Our integrated communication strategy included a refreshed brand identity, an optimised website, a landowner-specific brochure, and a targeted paid media campaign across social media and digital platforms. Key messaging across platforms emphasised the mutual benefits of collaboration and the environmental impact of the initiative.
Results & Impact: The integrated campaign reached an approximate audience of 675 million and secured 93 media placements. NatPower’s website traffic soared, with nearly 15,000 users generating over 20,000 page views. Paid media efforts delivered 2.8 million impressions, while social media engagement added over 1,800 new followers to NatPower’s platforms. These efforts resulted in many online enquiries, 55 of which were high-quality partnership opportunities. These results laid a strong foundation for building partnerships and scaling renewable energy efforts across the UK.

3.Celebrating Regenerative Farmers with We Feed the UK
In the face of climate change, biodiversity loss, and growing social inequalities, regenerative farming offers a path forward. We Feed the UK, paired award-winning photographers and poets with the UK’s most inspiring regenerative farmers and food producers to showcase their positive solutions and galvanise communities to think differently about how we produce and consume our food.
What We Did: We worked with the Gaia Foundation to amplify the stories of regenerative farmers across the UK within national, regional, consumer and trade media, helping their stories reach the public, and encouraging people to learn about and engage with regenerative projects in their area.
Results & Impact: The launch received widespread attention, securing 14 media placements – the highlights of which included a beautiful photo story in The Times, and an immersive episode of Radio 4’s The Food Programme featuring the project’s poets. Poets’ voices were also heard across regional radio stations in the week of the launch, bringing stories of regenerative agriculture direct to local people.
4. Tackling IUU Fishing with The Tuna Transparency Pledge with TNC
Tuna is a critical resource for global food security and economic stability, but overfishing and illegal practices jeopardise its sustainability. The Tuna Transparency Pledge, developed by TNC, aims to establish 100% monitoring on all industrial tuna fishing vessels by 2027. This initiative seeks to combat illegal, unreported, and unregulated (IUU) fishing while promoting transparency and accountability in seafood supply chains.
What We Did: Alongside TNC, we played a pivotal role in designing and launching the Tuna Transparency Pledge. We developed a cohesive new brand identity, crafted targeted messaging, and created a variety of informative fact sheets, infographics, social assets and an engaging hero animation to anchor the campaign. A phased paid media strategy targeted key stakeholders in the seafood industry, including retailers, suppliers, and policymakers. Additionally, we leveraged influencer engagement to amplify the campaign’s reach and credibility.
Results & Impact: The campaign generated over 1.3 million impressions and 5,800 clicks to TNC’s website, with the hero animation garnering 6,308 views in the launch period. Media efforts secured 28 articles in trade and environmental outlets, including Progressive Grocer and BusinessGreen. Influencers like Hugh Fearnley-Whittingstall and NGOs like Oceana and Pew endorsed the pledge, further solidifying its importance. The initiative sparked meaningful conversations among major retailers and seafood companies.

5. Demanding Action on Sewage Pollution on The Election Roadtrip with SAS
The state of the UK’s rivers and seas continued to be a pressing issue in 2024, with public engagement across the political spectrum. Surfers Against Sewage (SAS), a grassroots charity that has been campaigning on water quality and ocean health for over 30 years, launched their #EndSewagePollution Election Road Trip to spotlight the sewage crisis as a key voter concern ahead of the UK general election. Travelling across the UK in a bespoke double-decker bus, SAS engaged communities and political candidates in a nationwide conversation about water quality and environmental justice.

What We Did: We supported SAS with ongoing media engagement throughout the duration of the road trip. We coordinated interviews with SAS spokespeople, arranged photo opportunities, and conducted a comprehensive media sell-in to national, regional, and trade outlets. The campaign also leveraged thought leadership pieces and shared exclusive polling results to keep sewage pollution at the forefront of the news agenda.
Results & Impact: The Election Road Trip achieved 189 media placements, including features in The Times, ITV News, and The Guardian. Regional broadcast segments and high-profile interviews on Good Morning Britain amplified the campaign’s reach. Social media support from political leaders further galvanized public awareness. The campaign helped maintain SAS’s reputation as a leading voice in the fight for clean water.
6. Shifting the Narrative Through Stories for Change with Open Planet
Climate storytelling often leans heavily on negativity and fear, leaving audiences overwhelmed. Open Planet’s Stories for Change campaign seeks to shift this narrative by showcasing authentic, impactful climate stories through a global library of high-quality footage. By empowering changemakers with access to these resources, the campaign inspires action and fosters hope for a sustainable future.
What We Did: We developed an audience-centric campaign to elevate Open Planet’s library and its mission. We audited and optimised the Open Planet website and designed a paid media strategy featuring eye-catching videos and impactful storytelling with TikTok as a primary channel for engagement. Social media posts emphasized the beauty, diversity, and urgency of Open Planet’s message, driving traffic and encouraging participation.
Results & Impact: The environmental campaign delivered 20 million impressions and 9 million video views, with TikTok alone accounting for 8.9 million impressions and 290,000 link clicks. Open Planet’s platform saw 116 conversions on launch, including sign-ups and footage downloads. These results underscore the power of storytelling in driving climate action.
7. Uniting for Ocean Protection at COP16 with Bloomberg Ocean Initiative
Oceans are critical to life on Earth. Covering over 70% of our planet, the ocean generates over half of the oxygen on Earth, provides a home to diverse life, regulates our climate and sustains the livelihoods of billions. Yet, only 8% is designated as protected. The “Together for the Ocean” campaign, launched at COP16, aims to hold governments accountable for their pledge to protect 30% of the ocean by 2030. Founding partners include Bloomberg Ocean Fund, Blue Nature Alliance, Campaign for Nature and National Geographic Pristine Seas.
What We Did: Alongside the Bloomberg Ocean Initiative and other founding partners, we united a coalition of marine NGOs, stakeholders, and high-profile partners under the “Together for the Ocean” banner. We worked collaboratively to provide shared messaging, data, insights, media support, digital content and more to amplify the urgency of ocean conservation. We created the campaign concept, brand, messaging, campaign microsite and delivered an integrated launch at CBD COP16, running a press office on the ground including multiple press briefings, whilst engaging stakeholders and influencers.
Results & Impact: The campaign generated 652 media articles, reaching an international audience through outlets like BBC Radio 4, Reuters, and The Guardian. Social media efforts garnered 10 million impressions, while the launch film was viewed over 3 million times. High-profile endorsements from figures like John Kerry and Monica Medina elevated the campaign’s visibility and impact.

8. Empowering and Supporting Farmers across Africa with One Acre Fund
More than 50 million families in Sub-Saharan Africa rely on small farms for their livelihoods, contributing an estimated 80 percent of the continent’s food supply. However, agricultural yields across the region continue to lag behind global averages, leaving millions vulnerable to hunger and economic instability. One Acre Fund addresses this challenge by providing smallholder farmers with the financing, training, and tools they need to enhance productivity, achieve food security, and build sustainable futures.
What We Did: In 2023, we partnered with One Acre Fund to develop their first integrated communications campaign, focusing on the intersection of smallholder farming and climate resilience. Building on this foundation in 2024, we leveraged the brand identity to amplify the new campaign’s impact. A significant focus was identifying finance gap figures as a compelling media hook within the context of the ‘Climate Finance COP.’ We developed media materials, including a press release and targeted pitches for various outlets, from international and national media to agriculture trade and policy specialists. Greenhouse conducted an extensive sell-in at the launch of the climate campaign and sustained outreach leading up to and during COP28. This strategy brought the issue of climate finance for smallholders into the spotlight and ensured broad and impactful media engagement.
Results & Impact: The campaign and messaging achieved substantial cut-through in a highly competitive media landscape. By framing smallholder farming within the climate finance debate, we introduced a fresh perspective at COP29. One Acre Fund’s spokespeople became sought-after voices on the topic, with their insights featured in articles discussing the urgent need for increased funding for smallholders. The campaign had an estimated reach of 190 million people with 17 media placements, plus six spokesperson mentions and two op-eds. Media activity led to 399,000 views, solidifying One Acre Fund’s position as a thought leader in sustainable agriculture and climate resilience.

9. Advancing Understanding of Natural Capital with The Macdoch Foundation
Nature is essential for life and economic well-being yet, despite its importance, it remains undervalued. The Natural Capital Primer is a science-based resource designed to increase awareness and understanding of how businesses and society depend on natural ecosystems, and how we can better understand the value of nature using a concept called ‘natural capital’.
What We Did: Greenhouse partnered with Macdoch Foundation who developed the Natural Capital Primer, to develop campaign strategy, messaging, assets and launch a targeted paid media strategy. A hero video featuring prominent global voices on natural capital and a digital toolkit helped audiences understand the value of natural capital, while paid media efforts raised the profile of the Primer among business leaders and policymakers.
Results & Impact: The campaign delivered 617,000 ad views and 9,000 website clicks, with over 1,100 new LinkedIn followers joining the conversation. By highlighting the critical role of natural capital, the campaign has sparked interest in sustainable practices and policies.
10. Amplifying the Global Voice of Business Pioneering the Transition with WBCSD
The Business Breakthrough Barometer 2024, published by the World Business Council for Sustainable Development (WBCSD), is the first annual ‘pulse-check’ survey capturing insights from leading businesses on the opportunities and challenges of the net-zero transition. Developed by WBCSD with the support of Bain & Co, the Breakthrough Agenda, Marrakech Partnership and Race to Zero, the report features perspectives from industries accounting for over 70% of global emissions. The Barometer provides an overview of the state-of-play of the energy and industry transitions in 2024 and provides concise summaries for each sector; on the action businesses are taking, the barriers they are facing and what is required to scale-up investment.
What We Did: We collaborated with WBCSD and Bain & Co to co-create the report’s narrative and deliver an integrated campaign. This included campaign messaging, hero films, bespoke social media assets, webinar promotion, and a digital toolkit to amplify stakeholder engagement. Media outreach ensured that the Barometer’s findings reached international audiences, and we continued to promote the report’s key insights through media outreach at COP29.
Results & Impact: Coverage reached 89.1 million people through 33 articles in key outlets like FT Sustainable Views and BusinessGreen. Social media assets garnered significant engagement, while interviews with WBCSD partners at Climate Week New York showcased progress and opportunities for collaboration.

11. Taking 32 European Governments to Court for Climate Inaction with GLAN
Youth4ClimateJustice amplifies young voices in climate litigation, holding governments accountable for their role in the climate crisis. In 2023-24, the organisation raised awareness of cases before the European Court of Human Rights, underscoring the urgency of stronger climate action. On April 9, Europe’s top human rights court ruled the Duarte Agostinho case inadmissible. However, in the Klimaseniorinnen case, it determined that the Swiss government’s failure to reduce greenhouse gas emissions constituted a violation of citizens’ rights—a landmark decision setting a precedent for future climate litigation. As noted by Corina Heri: “It feels like a mixed result because two of the cases were inadmissible. But it’s actually a huge success.”
What We Did: We worked with GLAN on a campaign to prepare for every outcome, ensuring the narrative remained one of hope and progress. We provided comprehensive communications support, including press management, social media strategy, and influencer engagement. We crafted positive narratives around the litigation, hosted a messaging workshop, and managed Youth4ClimateJustice’s social media channels. We engaged high-profile stakeholders and influencers to amplify the campaign’s reach and secured widespread media attention.
Results & Impact: Despite mixed rulings, the campaign generated widespread media attention and maintained momentum for climate litigation. We secured 3,300 media placements, including coverage in leading outlets such as the BBC, Reuters, The Guardian, the Financial Times, and Al Jazeera. Media mentions of the Duarte Agostinho case reached over 108 million readers worldwide, with coverage spanning 105 countries. On social media, the campaign achieved 75,500 impressions and 17,900 video views across Twitter and Instagram. High-profile endorsements and strong social media engagement ensured the campaign remained focused on driving systemic change.

12. Amplifying food systems leadership with the ACF
At COP29, the Alliance of Champions for Food Systems Transformation (ACF) reaffirmed its leadership in advancing a bold vision for global food systems transformation. The initiative highlights country-led efforts and collaborative action to tackle the interconnected climate and food crises. By adopting a ‘whole-of-government’ approach, government signatories are driving systemic change and inspiring others to act with greater urgency to achieve better outcomes for people, nature and the climate.
What We Did: We provided strategic communications support to amplify ACF’s voice and strengthen its influence. Our efforts included developing impactful media materials to tell ACF’s story effectively and organising a high-level press conference on Food and Agriculture Day.
The press conference, moderated by Forbes journalist Daphne Ewing-Chow, featured:
- Sir David Nabarro, Special Envoy on COVID-19 for the World Health Organisation and Sustainable Development Advocate
- Lars Aagaard, Minister for Climate, Energy, and Utilities, Denmark
- Moisés Savian, Secretary of Land Governance, Territorial and Socio environmental Development, Ministry of Agrarian Development, Brazil
- Paul Gulleik, Ambassador and Special Envoy for Food Security, Norway
- Esther Penunia, Secretary General of the Asian Farmers Association and founding member of Family Farmers for Climate Action
To further build awareness and momentum for ACF’s mission, we developed tailored country snapshots and a digital communications toolkit to highlight progress, facilitated global media outreach, and led strategic stakeholder engagement.
Results & Impact: Through these efforts, ACF achieved significant visibility and strengthened its credibility within the food systems and climate community. The initiative secured 68 pieces of media coverage, reaching an estimated audience of 2.03 million. Highlights included features in The Guardian, Reuters, Carbon Brief, BBC World Service, Devex, The Mirror, IISD, Forbes, and FT Sustainable Views. The successful press briefing and coordinated media engagement ensured ACF’s leadership and progress were amplified across a diverse international audience. These results reflect ACF’s growing prominence and its ability to shape the global conversation on food systems transformation, inspiring action despite a challenging news agenda.
