Tappx cuts emissions by 18% despite increasing advertising activity by 74%

Tappx reduced its total carbon emissions by 18% during 2025, bringing them down to 101 tCO₂e, while increasing the volume of advertising requests processed by 74%. The AdTech company has published the results of its carbon footprint report, which reflect improved operational efficiency despite the growth in its activity.

The most significant figure lies in the relationship between emissions and activity. Tappx reduced emissions per billion ad requests by 53%, also known as requests. This trend shows that the company has managed to process a greater volume of advertising activity with a proportionally lower impact.

The results relate to the 2025 financial year and form part of the decarbonisation strategy that Tappx has been developing since 2022. The company bases this process on measuring its emissions, implementing specific measures, improving its operations and raising employee awareness.

Technology infrastructure accounts for most emissions

Servers remain Tappx’s main source of emissions. In 2025, they accounted for 57.2% of the company’s total carbon footprint. At the same time, technology infrastructure continues to be one of the main areas of focus for reducing the environmental impact of its operations.

Emissions associated with this infrastructure fell by 19.7% compared with 2024. Taking the start of carbon footprint measurement as a reference, the cumulative reduction since 2022 has reached 45%.

According to the company, these figures reflect the impact of the optimisations applied to its technology systems. Ongoing improvements in infrastructure efficiency make it possible to reduce emissions linked to an activity that has continued to grow over the same period.

The performance of its servers is particularly important for Tappx because of the nature of its business. The company provides multiplatform digital advertising solutions and processes ad requests for apps, websites and connected TV. As a result, optimising technological resources is one of the main ways to reduce its carbon footprint.

Lower emissions linked to business travel

Business travel was another area that showed notable progress in 2025. Emissions resulting from business travel fell by 45.5% compared with the previous year.

The company attributes this reduction mainly to a policy that prioritises more sustainable forms of transport and seeks to minimise the number of flights. This decision forms part of the measures implemented by Tappx to reduce emissions generated by its operations.

The reduction in travel adds to the improvement recorded in technology infrastructure and contributes to the overall decline in the carbon footprint. Taken together, the measures implemented have enabled total emissions to fall while the volume of advertising requests processed has increased.

A continuous improvement strategy since 2022

Tappx began estimating its carbon footprint in 2022. Since then, the company has maintained a strategy based on accurately measuring its emissions and implementing actions designed to reduce the impact of its activity.

These areas of work include infrastructure optimisation, the use of internal metrics and awareness programmes aimed at employees. The objective is to identify the activities that generate emissions and progressively improve their efficiency.

The 2025 results consolidate this strategy. The company has not only reduced its total emissions, but has also improved the performance of its operations in relation to the volume of activity. The 53% fall in emissions per billion advertising requests summarises this progress.

Daniel Reina, CEO of Tappx, says that sustainability has greater value when it translates into concrete operational decisions. “This report demonstrates that the measures implemented to optimise our infrastructure and processes are tangibly reducing our environmental impact, while we continue to grow and provide the best service to our clients,” he says.

The executive adds that the company is committed to continuing to progress through innovation and continuous improvement.

Tappx, a multiplatform AdTech company

Tappx provides monetisation, user acquisition and advertising solutions for apps, web and CTV. Its proprietary technology enables publishers to maximise their advertising revenue, while providing brands and agencies with greater trust and transparency.

The platform processes more than 80 billion ad requests per month worldwide, according to information provided by the company. In addition to its monetisation services, Tappx offers programmatic advertising and user acquisition solutions.

These tools enable advertisers to work with premium and owned inventory, optimisations based on key performance indicators and advertising creatives. The company also offers payment models such as CPC, CPA and CPI, in which brands pay according to the agreed outcome.

Founded in 2013 by Daniel Reina, CEO, and Antonio Hervás, CTO, Tappx has received various industry awards. In 2025, it was selected again for the FT1000: Europe’s Fastest Growing Companies report, compiled by The Financial Times.

Previously, the company was named the second-fastest-growing advertising company in Europe in the 2020 FT1000. It also received the award for Best AdTech Company to Work for in Spain at the 2023 PS Awards and was a finalist for SME of the Year at the 2022 CEPYME awards.

The development of its carbon footprint in 2025 adds a new indicator to the company’s track record: business growth has taken place alongside a reduction in total emissions and improved efficiency associated with processing advertising requests.
