In the fast-paced world of policy-making and industry regulations, standing out in the crowded space of digital advocacy can be a real challenge. But that’s exactly what Natural Mineral Waters Europe (NMWE) achieved in Brussels. When the European Union launched discussions around the Packaging and Packaging Waste Regulation (PPWR), NMWE saw an opportunity to make its voice heard and take an active role in shaping the future of recycling and packaging waste management across Europe.
From March 2023 to March 2024, their agency partner, The Right Street, launched a highly targeted digital campaign aimed at positioning itself as a key player in the conversation. By harnessing the power of platforms like LinkedIn and X (formerly Twitter), the campaign engaged EU decision-makers, industry stakeholders, and the media with a mix of engaging content—videos, infographics, and impactful visuals.
The results? A 13-spot leap in their influence ranking—from 36th to 23rd—within just one year. With a potential reach of 69.4K on X alone, the campaign not only boosted NMWE's visibility but also solidified its position as a leading voice in the PPWR discussions. This campaign serves as a prime example of how social media can be leveraged as a powerful tool to influence policy and drive industry change.
And it’s this kind of sharp, impactful strategy that the top CEOs of social media marketing agencies in Brussels are constantly innovating with, turning social platforms into key drivers of conversation and change in today’s digital landscape.
