Recent reports from the European Patent Office (EPO) and other global intellectual property bodies highlight an unprecedented growth in patents for green technologies, with a specific focus on sustainable construction, green building materials and innovative waste management solutions.
In 2023 alone, green tech patent filings rose by over 33 percent, illustrating the industry’s shift towards eco-friendly innovation.
This momentum also shows the increasing role of AI in green tech. While AI patent filings overall have slowed, green AI technologies have emerged as a very specific but fast-growing category, now constituting 4 percent of AI patent filings globally.
Mike Williams, an AI lead at Marks & Clerk, emphasizes that companies are using two decades of AI advancements to tackle environmental challenges, both in the construction industry and otherwise, predicting further growth in AI-driven green technologies.
Green Technology Patents in Construction and Renewable Energy
The rapid rise of green technology patents reflects the building sector’s commitment to sustainable practices. Recent innovations cover many areas, from carbon-sequestering materials to adaptive AI systems for energy optimization. These technologies not only promise environmental benefits but also enhance efficiency and cost-effectiveness across the construction lifecycle.
1. Carbon-Sequestering Concrete
Among the most groundbreaking patents is one for carbon-sequestering concrete, which actively absorbs CO2 during the curing process. This material transforms buildings into carbon sinks, significantly reducing the sector’s carbon footprint. By integrating recycled materials, this innovation lowers the environmental impact of construction projects while aligning with global climate goals.

2. AI-Driven Energy Optimization Systems
AI is gaining an important role in green building technologies. Patents in this category focus on dynamic load management and energy-efficient storage systems that optimize energy usage in smart buildings.
These systems use real-time data to balance electricity loads and store excess renewable energy, allowing for efficient energy management and reduced waste in relation to building and home energy consumption.
3. Next Generation Solar Panels
Several efforts are underway to create more efficient solar panels. One of which is the development of a highly efficient design described in patent US11567890B2. Using perovskite materials, which excel at absorbing light, as well as a tandem cell structure designed to maximize energy conversion, these solar panels promise a higher level of efficiency than traditional silicon panels, which will ultimately lower the cost of solar energy.
4. Sustainable Insulation Materials
Patented green insulation materials incorporating recycled and biodegradable components are another key development. These materials improve thermal efficiency while reducing reliance on non-renewable resources, aligning with the growing demand for eco-friendly solutions.
5. Waste Management Innovations
The surge in construction waste has spurred innovation in sustainable waste management. Patents for AI-enabled sorting and recycling systems streamline the reuse of construction debris, minimizing landfill contributions.
Regional Trends and Global Implications
Europe leads the charge in green patent filings, with European applicants filing 50 percent more green patents than their U.S. counterparts at the EPO. This aligns with Europe’s regulatory framework and financial incentives for green innovation, such as the EU’s Net-Zero Industry Act, which mandates a 40 percent production of net-zero technologies by 2030.
Meanwhile, patent filings from Asia and North America are also notable, driven by investments in renewable energy, sustainable transportation and advanced waste management technologies. Globally, AI-driven clean technology patents now represent nearly 12 percent of total patent activity, reflecting their important role in the energy transition and climate mitigation.
