An exciting paper discovery. What is the carbon footprint of 1 ton of CO2❓🤓 I recently stumbled upon a fascinating paper that aims to provide insights into the carbon footprint of captured CO2. It contains some surprising findings 🌍🔍. 𝐀𝐛𝐬𝐭𝐫𝐚𝐜𝐭 𝐇𝐢𝐠𝐡𝐥𝐢𝐠𝐡𝐭𝐬: The study reveals that the carbon footprint of CO2 as a feedstock varies significantly based on the source and energy demand for capture. Surprisingly, these footprints range from -0.95 to -0.59 kg CO2 eq. per kg of CO2 today, and -0.99 to -0.98 kg CO2 eq. in a low carbon economy. This variation is primarily due to the wide range of methodological choices in current Life Cycle Assessment (LCA) practices. 𝐖𝐡𝐲 𝐓𝐡𝐢𝐬 𝐌𝐚𝐭𝐭𝐞𝐫𝐬: Anthropogenic CO2 emissions are driving global warming, and capturing CO2 for use in chemicals, fuels, or polymers is usually sold as part of the solution. However, to make a real impact, we must prioritize the most environmentally beneficial CO2 sources. This paper emphasizes the importance of using consistent LCA methodology to avoid making poor decisions in carbon capture and utilization (CCU). 𝐊𝐞𝐲 𝐓𝐚𝐤𝐞𝐚𝐰𝐚𝐲: An experienced LCA practitioner is crucial for navigating these complexities and ensuring that we identify the best methodological approach. A consistent and rigorous application of LCA standards can lead to better decision-making and more effective emission reductions. #Sustainability #ClimateChange #CarbonFootprint #LifeCycleAssessment #CCU #GHGEmissions #EnvironmentalImpact #GreenEconomy https://lnkd.in/dBQryYAY
In a simple A4 world where the only tool one have to solve problems is a hammer 🔨 all solutions seems to look like a nail. Carbon Dioxide emissions is not a gas formel of only carbon, oxygen and water molecules but a cluster of a variation of attached isotopes and the definition CO2 is not covering the issue of “climate” at all. Carbon is natures building block and has no negative effects or impacts on nature or climate at all, the same goes for the carbon dioxide emissions from a human or cow exhaling. This gas formal is coined “the creation formula” as it natures own development of photosynthetic processes the past 2,6 billion years making all parts of our molecular world circulating, reusable when clusters are split or used in the regenerative processes in natures biodiversity world. This CO2 is necessary for all life forms to thrive and regenerate, this emission is not polluting and have no negative effects on climate change as long as this balance is not maintained. When we remove trees we cut the branch we are sitting on, when the trees 🌴 🌳 is no longer able to “sequester carbon dioxide” from the air and release oxygen and water molecules we have a huge problem from deforestation and not from cows and animal life.

9moHey Fabian Diaz, thank you for raising the topic. The PCF of captured CO₂ depends on two things: - energy source, which can be the national mix (including e.g. coal) or specific technologies, such as wind power (with storage) - the CO₂ concentration of the source. If you take CO₂ from the air, this is ~420 ppm. If you take CO₂ from a flue gas, the concentration is higher and the energy demand smaller. If you produce ammonia from natural gas, you have to remove the CO₂ anyway, because otherwise your catalyst is screwed. Good for the catalyst producer, bad for you. Could you please elaborate on this: "wide range of methodological choices"
