Rethinking Fertilizers: Green Ammonia and Sustainable Agriculture

In the 19th century, Europeans discovered the agricultural miracles of guano, ammonia-rich bird droppings. Fast forward to the early 1900s, when Fritz Haber and Carl Bosch invented the synthetic ammonia method, which revolutionised fertiliser production. However, this method relies heavily on fossil fuels, resulting in significant CO2 emissions.

Companies such as Starfire Energy are now innovating in response to climate concerns. They are developing green ammonia production systems based on renewable energy, air, and water. Joe Beach, co-founder of Starfire Energy, emphasises the advantages, which include lower environmental impact and safety precautions owing to the pungency of ammonia. By utilising abundant nitrogen and hydrogen resources, these programs aim to transform agriculture sustainably, eliminating dependency on polluting fertilisation technologies.

Breaking the Barrier: Reviving Europe’s Rivers by Demolishing Dams
Europe's Rivers

A new movement is gaining popularity in the heart of Europe, advocating for the restoration of natural streams by removing artificial barriers that have long hindered their flow. The positive impacts of these efforts are best seen along the gorgeous banks of Finland’s Hiitolanjoki River.

The removal of dams built between 1911 and 1925 has sparked a spectacular ecological rebound, particularly for endangered wild salmon species. Its tremendous success demonstrates the possibility of balancing ecological restoration with commercial interests and serves as a powerful monument to the power of community action in reviving vulnerable aquatic ecosystems across the continent. 

Building Sustainable Structures: Advances in Textile-Reinforced Concrete Technology

Chalmers University of Technology has developed ground-breaking technology for building environmentally sustainable structures with textile-reinforced concrete. This innovation decreases material utilisation by replacing steel with fabrics, resulting in lightweight buildings with far lower carbon impact. Professor Karin Lundgren emphasises the potential to reduce cement usage, which is a significant source of CO2 emissions in concrete manufacturing. This breakthrough attempts to reduce the environmental impact of construction while also encouraging the development of sustainable infrastructure. 

Rebuilding Trust in Carbon Markets: Assessing Nature-Based Climate Solutions.

Nature-based climate solutions are critical in addressing climate change, potentially supplying around one-third of the mitigation required to meet climate targets set by the Paris Agreement. However, obtaining funding for these ideas has been hampered by a lack of strong scientific evidence and accountability.  A recent study in Nature Climate Change by 27 authors from 11 institutions examines over 40 climate solutions, with tropical and temperate forest protection and reforestation being the most academically viable possibilities.

Despite the challenges in carbon markets, using them for financing remains critical. The study underlines the need for better implementation strategies to reestablish confidence and achieve effective climate action. These insights can steer policymakers, firms, and investors towards better-informed and impactful initiatives.
