Although headquartered in the UK, Next 15 Group has a presence in 16 countries.¹⁸“Home,” Next 15. Archived July 6, 2025. Archive URL: http://archive.today/BlfwW It has at least 27 subsidiary companies,¹⁹See related organisations section below 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).²⁰“How We’re Different,” Next 15.

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 2023.²¹“Our History,” Next 15. Archived July 6, 2025. Archive URL: http://archive.today/yswoN  

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.²²“Mach49,” Next 15. Archived May 24, 2025.

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,”²⁵“Next 15 Group plc Annual Report 2025,” Next 15. Archived July 6, 2025. Archived .pdf on file at DeSmog. Archive URL: http://archive.today/4RENH 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.”²⁶“How We’re Different,” Next 15. Archived June 29, 2025. Archive URL: http://archive.today/1hIkh

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.”²⁷Next 15 Carbon Reduction Plan,” Next 15, May 22, 2025. Archived June 21, 2025. Archive URL: http://archive.today/cHppV

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.²⁸“Next 15 Carbon Reduction Plan,” Next 15, May 22, 2025.

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) committee²⁹“Corporate Governance,” Next 15. Archived July 7, 2025.

The campaign targeted business leaders, as well as government officials and the broader society.

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.
