In Brief

🌎 ff.1.1 Awareness and Art
COP26's artistic project revolutionized the conference's visual identity, highlighting the importance of art in raising awareness about climate change.

📉 ff.1.2 From 51 Billion to Zero
From 51 billion to zero: the urgent need to reduce global CO2-equivalent emissions, currently at 51 billion tons per year, to combat climate change.

🛴 ff.1.3 Will Electric Scooters Save Us?
80% of journeys in the USA are less than 16 km, suggesting a potential transformation of urban mobility through e-bikes and electric scooters.

🏭 ff.1.4 Capturing CO2 Will Be Important
CO2 capture technologies could become economically accessible at less than $100 per ton, with the cement and steel industry as primary targets.

🇫🇮 ff.1.5 The Energy Consumption of Bitcoin
Bitcoin's energy consumption equals that of all of Finland, but the use of renewable energy in mining could mitigate its environmental impact.

⚡ ff.1.6 Nuclear Fusion
Nuclear fusion, once predicted for the early '90s, now aims at 2035 as a milestone to demonstrate a clean fusion process.

🔋 ff.5.2 Duracell? No, Tesla
Not just cars: With 3 GWh of capacity, Tesla controls a significant portion of the world's energy storage potential and aims to reach 1,500 GWh by 2030.

🚲 ff.5.3 Pedal-assist
During the pandemic, e-bikes outsold electric cars (500k bikes vs. 250k cars in the United States).

😎 ff.5.4 The Tesla of Bicycles
If e-bikes are the next frontier of mobility, Van Moof is the Tesla of two wheels.

🧱 ff.5.5 Marchetti's Wall
A universal constant hour: the travel time limit that influences life and work choices.

⚰️ ff.5.6 The Danger of Traffic Worldwide
And while you're in traffic, keep an eye on the road. We drive excellently in Europe (except for those wearing hats).

🎵


🚲 ff.20.1 The Revenge of Bicycles
The pandemic has increased bicycle use, with notable growth in the Philippines and progress in Italy with the increase in bike lanes.

🇮🇩 ff.20.2 Jakarta's Example
In Jakarta, bicycle use has increased sixfold, highlighting a significant shift towards sustainable mobility.
Air quality in Jakarta has improved after COVID (thanks to sustainable mobility).
🧠 ff.33.1 The Philosophical and Cognitive Value of Trees
Exploring the historical and cultural connection between humanity and plants, highlighted by the inspiration for search algorithms like the decision tree.

🍁 ff.33.2 CO2 Collectors
A study on how plants capture and store CO2, with a focus on storage efficiencies in forests and peatlands, showing the importance of biodiversity and innovative seeding technologies.

🏭 ff.33.3 Plants Modified to Capture CO2
Advanced genetic techniques like CRISPR are used to increase plants' ability to convert CO2 into stabilized carbon, an approach supported by significant investments in plant genetics.

🧮 ff.33.4 Computational Molds
The Plasmodium, a mold used to solve combinatorial optimization problems like the Traveling Salesman Problem, demonstrates the potential of biological systems for computing and designing efficient and resilient networks.

🏙 ff.34.1 More and More City Dwellers
We are increasingly living in urban areas, with a percentage increase in the population living in cities.

🚦 ff.34.2 Rethinking Cities: Mobility and Traffic
COVID and remote working have improved traffic conditions, but to what extent?

🚦 ff.34.3 Rethinking Cities: Livable Spaces
Projects that have given space back to greenery and canals make cities more livable.

🥵 ff.34.4 Rethinking Cities: Heat
Summer heatwaves highlight the importance of green areas in cities to mitigate heat.

🏙 ff.34.5 It's All Monoculture
Cities as examples of monoculture and homogenization, dominated by cars and traffic.

💚 ff.51.1 The Green Narrative
Reflections on how nature, a symbol of hope and inner peace, becomes the subject of a romantic narrative, which sometimes risks distorting the pragmatic reality of its existence and utility.

🛐 ff.51.2 Ecology = Religion?
A critical analysis of the possible similarities between the modern approach to ecology and religious practices, questioning the existence of a green faith based more on emotional beliefs than on rational and scientific actions.

🔥 ff.51.3 Your Heretic Dream
Are climate changes exaggerated by the media? A prompt to consider a more balanced approach that includes innovative and adaptive solutions, also evaluating the return on investment of climate policies compared to public health, education, and poverty reduction.

⚖️ ff.61.1 Measuring Pollution in Life Hours
Converting CO2 emissions into perceivable life time makes the environmental impact of our daily choices tangible.

10 tons of CO2 annually represent the global per capita target of emissions for sustainable living.

27 kg/day → 1 kg/h → 20 g/min

🕗 ff.61.2 Emissions Converted into Time
Analyzing emissions through the time-CO2 equivalence, we identify daily activities and their impact in lost life hours.
