Next 15 Group

Background

Next 15 Group is a business growth consultancy and advertising company¹^,² that has worked with major meat and dairy industry players such as the Global Roundtable for Sustainable Beef³, Lactalis,⁴ and Arla Retail.⁵

Although headquartered in the UK, Next 15 Group has a presence in 16 countries.⁶ It has at least 27 subsidiary companies,⁷ although it specifies on its website that it is not a holding company, but rather a “decentralised network.” Next 15 Group’s four key areas of focus are consumer insight (helping companies to understand their customers), customer engagement (assisting the companies to engage with their customers), customer delivery (improving the way companies interact with their customers), and business transformation (for example, helping companies with their overall strategy).⁸

Next 15 Group also refers to itself as the “Next Network.” It was founded in 1995 as Text 100, changing its name to OneMonday Group in 2000, and then to Next Fifteen Communications Group plc in 2002. It became Next 15 Group in 2023.⁹

In June 2025, Next 15 Group announced the discovery of potential serious misconduct at one of its subsidiaries, Mach49—an agency that specializes, among other areas, in the energy sector.¹⁰ Next 15 did not disclose the details of these concerns, but terminated the contracts of three senior managers at Mach49, and the CEO of Next 15 retired.¹¹ According to Sky News, Next 15 has subsequently been holding talks about selling its “legacy” assets, which are understood to include its public relations agency MHP.¹²

Stance on Climate Change

Next 15 Group says that its goal is to “Make sure we leave the world a better place than we found it,”¹³ and that “For Next 15, sustainability is a cornerstone of our business strategy. We recognise its vital role in achieving lasting success and creating a positive impact on society and the environment.”¹⁴

Next 15 has committed to reaching net-zero emissions by 2050. It also set a target to reduce emissions by 42% by 2030, relative to a 2020 baseline. However, in 2025, Next 15 estimated its Scope 1, 2, and 3 emissions at 55,740.7 tCO₂e—more than double its 2020 baseline of 26,410.9 tCO₂e.”¹⁵

Next 15 had planned to submit its emissions reduction targets to the Science Based Targets initiative (SBTi)—a corporate climate action organization that provides standards, tools, and guidance to help companies set greenhouse gas (GHG) emissions reduction targets to reach net-zero by 2050—at the start of its 2025 financial year. However, the company missed its self-imposed deadline, citing “significant changes” that prevented it from establishing a suitable emissions baseline. Next 15 says that “our commitment to being science-aligned in our approach remains firm.” At the time of writing, to DeSmog’s knowledge, they have not set a revised target date for submission to SBTi.¹⁶

Next 15 has not declared its advertised emissions—the additional emissions resulting from increased sales of polluting products as a result of advertising.

Climate governance at Next 15 encompasses an ESG (Environmental, Social, and Governance) committee¹⁷ and an internal sustainability group, known as “Green 15.” Green 15’s “primary goal is to continually build awareness and create as much opportunity to engage everyone in our initiatives across the Group and positively influence in support of a greener, more sustainable way of living.”¹⁸

Next 15 says that “our intention is to work with clients who have sustainable business models and are committed to the low-carbon transition,”¹⁹ and that “we’re not afraid to turn away profitable work that has a negative impact.”²⁰ Next 15 has acknowledged that working with clients in the oil and gas industry poses both a reputational and financial risk, however it has not eschewed working with clients in the fossil fuel sector, saying instead that “we do not work with clients in the fossil fuel extraction sector unless it is to help them materially change the course of their business to have a more positive impact.”²¹

A Next 15 Group subsidiary, Elvis, has signed the Clean Creatives pledge to decline future contracts with the fossil fuel industry.”²² In 2025, Elvis signed a petition calling for a ban on fossil fuel advertising in the UK.²³ Both Elvis and another Next 15 subsidiary, Archetype, have B Corp status,²⁴ a certification that recognises businesses that meet high standards of social and environmental performance.

Funding

For the year ending 31 January 2025, the Next 15 Group made £729.8m in revenue.²⁵

In June 2025, Next 15 Group announced that it had uncovered potential serious misconduct at one of its subsidiaries, which led to Next 15 warning that its 2026 profit would likely be below market expectations.²⁶

Since 2004, the Alternative Investment Market (AIM) has listed Next 15 Group.²⁷ AIM is a sub-market of the London Stock Exchange for smaller companies.

Of Next 15 Group’s shareholders,²⁸ Aviva Investors and Aberdeen hold significant fossil fuel assets.²⁹^,³⁰

In its 2024 and 2025 annual reports, Next 15 Group reported on how climate change affects its financial position and operations (Climate-related Financial Disclosures).³¹ In 2024, Next 15 Group said that one of its main climate-related risks was “Exposure to sectors/clients with higher exposure to climate-related risks” and acknowledges that “There is a risk that if we work with sectors with the highest levels of transition risk, such as oil and gas, we lose revenue as they struggle to adapt to different climate scenarios. This could also negatively impact our reputation.”³² In 2025, Next 15 said that “we expect that the market opportunity from a transition to a circular economy will have a net positive impact on our business. This is driven by our strategic intent to contribute to accelerating positive impacts (such as circularity, inclusion, wellbeing and job creation) and/or reduce negative impacts (such as overconsumption, climate change and biodiversity loss) through client work.”³³

Actions

2024

Archetype, a subsidiary of the Next 15 Group, developed a campaign for BayWa r.e., a renewable energy company owned by BayWa AG—a conglomerate with interests in energy, fossil fuels, and agriculture.⁵³^,⁵⁴

The campaign targeted business leaders, as well as government officials and the broader society. Archetype utilized social listening, a process that identifies and analyzes what is being said about a topic on social media platforms, to collate online mentions of the COP conferences between 2017 and 2021 and produce a report.⁵⁵ In the campaign, Archetype “compared online mentions of COP26 with those of the first series of Netflix sensation Squid Game, drawing parallels between the dystopian landscape in the show and the one on our horizon.”⁵⁶

Archetype also produced a thought leadership platform, which it promoted through media outreach, social media, and an “emotive” campaign video about the climate crisis. Archetype states that this campaign enabled BayWa r.e. to break into the business and mainstream media.⁵⁷

2024

In 2024, Next 15 Group subsidiary Savanta worked for the Institute for European Environmental Policy to conduct research used in the development of the European Green Deal Barometer, a report that assesses the progress of the European Green Deal‘s policy.⁵⁸

2023

In its 2023 annual report, Next 15 Group disclosed that it had worked for the UK government to develop a Net Zero System Tool (‘NZST’). The tool is designed to help decision-makers understand the relative impacts of different policy options and to enable the government to systematically assess how various choices might affect progress toward net zero. One area of analysis included the potential impact of policies aimed at reducing meat consumption.⁵⁹

2022

Outcast, a Next 15 Group subsidiary, promoted Bloomberg Philanthropies’ Countdown to COP27 campaign using organic and paid social media content, Google search ads, and community management. Next 15 said that it also involved engaging with “US Special Presidential Envoy for Climate, John Kerry, Goldman Sachs, UN Secretary-General António Guterres, French diplomats, and more.”⁶⁰

2022

In March 2022, Next 15 Group acquired Engine Group UK. Engine Group UK was the parent company of MHP,⁶¹ an agency working for the Global Roundtable for Sustainable Beef (GRSB).⁶² The GRSB is a membership organization that represents stakeholders across the entire beef supply chain. Its stated mission is “to advance, support, and communicate continuous improvement in sustainability of the global beef value chain,” with a vision for “a world where beef is a trusted part of a thriving food system.”⁶³

MHP had worked for GRSB since 2020.⁶⁴ Its work, described in detail in a DeSmog investigation, had included creating a strategy aiming to promote GRSB as “power[ing] progress in sustainable beef” and to assure people that there was “growing momentum in the beef industry to protect and nurture the earth’s natural resources.”⁶⁵

GRSB extended its contract with MHP in February 2022,⁶⁶ shortly before MHP was acquired by Next 15.⁶⁷ Under the renewed agreement, MHP was to be paid £6,000 per month for its ongoing work.⁶⁸ As part of MHP’s remit under the renewed agreement, GRSB requested that MHP map major industry events in 2022 to “help GRSB identify and increase potential speaking opportunities and member attendance.”⁶⁹

MHP supported the GRSB in its preparations for its Global Conference and COP27,⁷⁰ launching a communications campaign in September in advance of the conferences.⁷¹

2021

Next 15 Group subsidiary Savanta conducted research for the WWF as part of their Eat4Change initiative. This research involved Savanta surveying adults across the EU on their attitudes towards food, with the results informing WWF’s work with national retailers, politicians, and EU decision-makers involved in communicating EU action on deforestation, both within the European Commission and Member States.⁷²

2016

Next 15 produced an app for Public Health England called “One You,” which aimed to help those aged 40-60 build healthier habits. This app included components relating to diet.⁷³

CORRECTION (08/08/2025):This profile was corrected to make it clear that MHP was acquired by Next 15 Group in March 2022 and that MHP’s work for the Global Roundtable for Sustainable Beef prior to March 2022 was therefore not the Responsibility of Next 15 Group.
