Carswell Gould’s New ESG Policy to Aid Business Sustainability

Hampshire agency applies sustainability principles to marketing operations

A Hampshire-based marketing agency has published details of its approach to reducing environmental impact while helping clients communicate sustainability work. Carswell Gould says it sees a gap between what many organisations commit to on sustainability and what they deliver in practice. The agency now frames its own work as part of an effort to close that gap, both internally and through the campaigns it produces for clients.

This matters because marketing agencies increasingly influence procurement decisions, supplier selection, and campaign delivery methods. Those choices carry carbon consequences. Consequently, agencies face growing pressure to demonstrate their own environmental credentials, not just promote those of their clients.

Carswell Gould has published a sustainability policy that covers its operational footprint, supplier standards, and client project delivery. The company uses renewable electricity and sustainable web hosting. It also says it holds a British Gas Zero Carbon Certificate. However, the agency acknowledges its supply chain carries a larger environmental footprint than its direct operations, particularly in print and production work.

The policy commits the agency to tracking energy use, waste, and the carbon impact of digital campaigns. This includes measuring emissions from ad delivery and web traffic. Carswell Gould says it will publish an annual impact update through its newsletter. Therefore, clients and peers can track whether the agency meets its commitments over time.

Marketing agencies face scrutiny over environmental claims

Marketing and advertising carry a dual environmental impact. First, agencies have their own operational footprints, including energy use, travel, and office waste. Second, the campaigns they create generate emissions through production, distribution, and media delivery.

Digital advertising may seem low-impact compared to print or broadcast media. Nevertheless, it generates measurable carbon emissions through data centres, network infrastructure, and device energy consumption. Carswell Gould says it is working to measure and reduce these impacts across client campaigns.

The agency’s policy states it will guide clients toward lower-impact campaign options. This includes recommending sustainable suppliers, reducing unnecessary print runs, and designing digital campaigns that minimise data transfer. Notably, the company says it wants to help clients make informed decisions rather than simply promoting green credentials without operational change.

This approach reflects wider pressure on marketing agencies. Clients increasingly ask agencies to demonstrate sustainability credentials before awarding contracts. Public sector tenders often require evidence of environmental management systems and carbon reporting. Meanwhile, private sector clients face scrutiny from investors and customers over supply chain impacts.

Operational commitments include renewable energy and supplier standards

Carswell Gould’s published policy outlines several specific commitments. The agency uses renewable electricity for its operations and has moved to web hosting powered entirely by renewable energy. It holds a British Gas Zero Carbon Certificate, which provides third-party verification of its electricity sourcing.

The company says it is building a preferred supplier list based on transparent sustainability credentials. This means evaluating print suppliers, production partners, and media vendors on environmental performance. The agency acknowledges this work is ongoing rather than complete.

Internally, Carswell Gould says it invests in team-wide sustainability training and seeks external expertise where needed. The policy also commits to tracking waste and energy use, though specific baseline figures and reduction targets are not yet published.

For client work, the agency says it will advocate for inclusive messaging and responsible ad targeting alongside environmental considerations. This suggests a broader ESG approach rather than focusing solely on carbon reduction.

The company’s transparency commitment is particularly significant. Many agencies publish sustainability policies but provide limited detail on progress or setbacks. Carswell Gould says it will communicate achievements and challenges openly through its twice-yearly newsletter. This creates accountability and allows external observers to assess whether commitments translate into measurable change.

Essential information for businesses evaluating agency partners

• Carswell Gould has published a sustainability policy covering operations, suppliers, and client project delivery.
• The agency uses renewable electricity and sustainable web hosting, supported by a British Gas Zero Carbon Certificate.
• It is developing guidance for lower-impact campaigns and measuring carbon emissions from digital advertising and web traffic.
• The company says its supply chain, especially print and production, carries a larger environmental footprint than direct operations.
• Carswell Gould will publish an annual impact update via its newsletter, providing accountability for its commitments.
• The agency says sustainability communication already forms a significant part of its work with larger organisational clients.

Commercial implications for UK businesses working with marketing agencies

This development matters for UK businesses in several ways. First, companies under pressure to reduce Scope 3 emissions must consider the carbon impact of their marketing and advertising spend. Scope 3 includes emissions from purchased goods and services, which covers agency work, media buying, and campaign production.

Second, public sector suppliers face specific requirements under PPN 06/21, which requires carbon reduction plans from larger contract holders. Marketing spend falls within scope if it forms part of a broader contract. Therefore, businesses bidding for public work need agency partners who can demonstrate credible environmental management.

Third, businesses face reputational risk if agencies produce campaigns that contradict their sustainability commitments. For example, a company targeting net zero might face criticism if its advertising agency uses high-carbon production methods or works with suppliers that lack environmental standards. Consequently, due diligence on agency partners becomes increasingly important.

Fourth, investors and lenders increasingly scrutinise environmental governance across the supply chain. Businesses reporting under TCFD or preparing for mandatory climate disclosures must consider their marketing supply chain. Working with agencies that track and report their own emissions makes this process easier.

Finally, customer expectations are shifting. Consumers and business buyers increasingly expect consistency between what companies say and what they do. Marketing agencies that help clients bridge this gap offer strategic value beyond traditional campaign delivery.

For SMEs, this creates both opportunity and complexity. Smaller businesses may lack the resources to conduct detailed due diligence on agency partners. However, agencies that publish transparent policies and measurable progress reports reduce that burden. Businesses can assess agency credentials more easily when information is publicly available and regularly updated.

Questions businesses should ask potential agency partners

When evaluating marketing agencies, businesses should ask specific questions about environmental management. These questions help distinguish between agencies making genuine progress and those using sustainability as a marketing message without operational backing.

First, ask whether the agency tracks its own carbon footprint. This includes direct emissions from operations and indirect emissions from suppliers and media delivery. Agencies that cannot provide this information may struggle to help clients manage their own marketing-related emissions.

Second, ask about supplier standards. Does the agency evaluate print and production partners on environmental performance? Can it provide evidence of supplier certifications or carbon reporting? Agencies with preferred supplier lists based on sustainability criteria can help clients reduce Scope 3 emissions.

Third, ask about digital campaign measurement. Does the agency track the carbon impact of digital advertising, including data transfer, ad delivery, and website hosting? This information helps businesses understand the full environmental cost of their marketing activity.

Fourth, ask about transparency and reporting. Does the agency publish regular updates on its sustainability progress? Can it share case studies of how it has helped other clients reduce campaign impacts? Agencies that report openly on both successes and challenges demonstrate accountability.

Fifth, ask about training and expertise. Has the agency invested in sustainability training for its team? Does it work with external advisors or hold relevant certifications? Agencies with deeper expertise can provide more credible guidance on sustainable campaign delivery.

These questions are particularly relevant for businesses facing tender requirements, investor scrutiny, or customer pressure on sustainability performance. Choosing an agency partner with robust environmental management reduces risk and supports broader sustainability goals.

How marketing decisions affect wider sustainability targets

Marketing sits at the intersection of multiple business functions, which means it influences sustainability performance across several areas. Campaign decisions affect procurement, supplier relationships, digital infrastructure, and brand reputation. Therefore, agencies that understand these connections can help businesses make more strategic choices.

Procurement decisions often rest with marketing teams when commissioning campaigns. Choosing print suppliers, production companies, media partners, and digital platforms all carry environmental consequences. Agencies that guide these choices toward lower-impact options help businesses reduce Scope 3 emissions without compromising campaign quality.

Supplier relationships extend beyond individual campaigns. Long-term agency partnerships create opportunities to improve environmental performance across the supply chain. For example, an agency might work with a print supplier to reduce waste, switch to renewable energy, or source sustainable materials. These improvements benefit all clients working with that supplier.

Digital infrastructure choices matter more than many businesses realise. Website hosting, content delivery networks, and advertising platforms all consume energy. Moving to providers that use renewable energy reduces campaign emissions. Similarly, optimising website code and reducing unnecessary data transfer cuts both carbon impact and operating costs.

Brand reputation depends increasingly on consistency between messaging and action. Customers, investors, and employees scrutinise companies for greenwashing or superficial sustainability claims. Agencies that help businesses demonstrate genuine progress through transparent reporting and evidence-based campaigns reduce this reputational risk.

For businesses committed to net zero, marketing represents both a challenge and an opportunity. The challenge lies in measuring and reducing emissions from a complex, often outsourced function. The opportunity lies in working with agency partners who treat sustainability as an operational priority rather than a marketing angle. Agencies like Carswell Gould that publish detailed policies and commit to measurable progress offer a model for this approach.

Finding additional guidance on sustainable business operations

Businesses looking for broader support on sustainability can access resources from several authoritative sources. The UK government provides guidance on carbon reporting, net zero planning, and environmental management through the Department for Energy Security and Net Zero. This includes resources specifically designed for small and medium-sized enterprises.

IEMA, the Institute of Environmental Management and Assessment, offers training and professional standards for sustainability practitioners. Businesses building internal expertise or evaluating external advisors can use IEMA resources to understand current best practice.

The British Standards Institution publishes standards for environmental management systems, carbon footprinting, and sustainability reporting. These standards provide frameworks that businesses can follow regardless of sector or size.

For businesses working with public sector clients, guidance on PPN 06/21 and carbon reduction plans is available through gov.uk. This helps suppliers understand requirements and prepare compliant documentation. Additionally, businesses seeking support with carbon reporting, net zero planning, or supply chain sustainability can explore structured compliance support that addresses regulatory requirements alongside commercial objectives.
