Clean Energy
It’s been a long and windy road but clean energy is now big business. Demand for smart and lower-carbon energy solutions is growing and these sectors will continue to be substantial drivers of the 21st century economy.
Antenna clients are pioneering new technology and business models in solar, storage, smart grid and biofuels and other key clean industries. The common thread is a commitment to a safe, sustainable, efficient and affordable energy future.
For more than 20 years, Antenna has planned and spearheaded thousands of integrated marketing & PR campaigns for the clean energy pioneers that are powering impact in this sector.
Circular Economy
The scarcity of raw materials coupled with consumer demand for transparency around the sustainability and origin of consumer goods has incentivized companies to develop circular supply chains. New technologies are unlocking value in waste, second-life plastics and materials and helping to realize a future of “no scrap left behind.”
Across multiple sectors and industries, Antenna clients are turning waste and carbon into energy, consumer products, and industrial solutions. Antenna leverages a wealth of domain expertise and strategic communications muscle to help circular technology companies define and penetrate new markets.
Sustainability
Antenna has unrivaled experience in delivering results for sustainable technology companies and organizations that are dedicated to improving critical systems for future generations.
Antenna clients are leaders in areas such as environmental sensors, sustainable materials, recycling and corporate social responsibility (CSR). CSR and sustainability concerns are no longer solely motivated by social justice concerns; increasingly, shareholders, customers, and government are demanding that companies take their sustainable footprint seriously. Antenna supports and manages communications efforts that amplify CSR initiatives and markets them effectively to an increasingly sophisticated marketplace.
Water
Antenna’s water technology clients are developing new approaches to preserving the world’s most precious resource. Their solutions include utilizing IoT and AI to improve water monitoring, quality and distribution; novel technologies for wastewater treatment and desalination; remote solar-powered water pumps; and advocacy on behalf of investment in water infrastructure, safety and efficiency.
Agriculture Tech
Farming doesn’t just happen on farms anymore. Exciting new technologies are bringing efficient, high-yield production of agricultural products to urban rooftops, repurposed industrial spaces and other new frontiers. Antenna clients are creating and connecting precision technologies that are driving more efficient and sustainable food systems.
Advanced Materials
A new class of materials has emerged that are stronger, lighter and more sustainable than their predecessors. From nanomaterials and recycled tires to 3D printing and lithium extracted from mining wastewater, Antenna clients are engineering new ways to build a stronger and more sustainable planet.
