“…Within each of the four urban carbon storage mediums, the considered options for sequestering carbon were identified based on their substantial mitigation potential and prevalence in the decarbonisation discussion relative to other approaches. This is however not a comprehensive list, and alternative methods for storing CO2 in urban areas such as concrete crushing alongside urban brownfield land management 167 , or photobioreactors in building facades [168][169][170] could be further explored.…”

Cities worldwide are increasingly committing to achieving net-zero carbon emissions in the coming decades. Most cities are not yet aware of the drastic changes in built environment required to reduce GHG emissions, and in many cases carbon neutrality targets will require atmospheric carbon removal outside or within city boundaries to offset remaining emissions. Since cities are particularly affected by increasing temperatures (e.g. due to the urban heat island effect), direct regulation of radiation through surface albedo management has also been suggested to alleviate these exacerbated urban heat impacts. With the aim of supporting the path to carbon-neutral cities, this paper assesses the existing literature on Carbon Dioxide Removal (CDR) at the urban scale, seeking to quantify the potential negative emissions contribution of cities globally. Our potential estimates indicate that deploying CDR options at the urban scale could make a significant contribution to global mitigation of climate change, alongside supporting the upscaling of climate action from local to regional and national scale. The associated human and environmental well-being effects strengthen the case for cities as carbon sinks. The upscale of the reviewed technologies is nevertheless constrained by numerous uncertainties, economic barriers and governance issues that pose substantial drawbacks to their implementation and scope, suggesting a future research agenda.

“…Among these, post-combustion CO 2 capture techniques, have gained prominence due to their low technological risk and retrofittable nature [7,8]. Various methods, such as adsorption, membrane processes, cryogenic distillation, and adsorption, have been suggested for CO 2 separation [6,9]. Among these options, cryogenic distillation is the most established, but its extensive use is hindered by significant energy consumption and high costs [10,11].…”

This study investigates the potential of activated carbon derived from ripe plantain peels (PPAC) for carbon dioxide (CO2) capture. PPAC was prepared through carbonization and activation using H3PO4, and its unique properties were extensively characterized which revealed irregular sponge-like protrusions and well-defined pores under Scanning Electron Microscopy (SEM). Elemental analysis identified carbon, silicon, and oxygen as major components, corroborated by X-ray Diffraction (XRD) analysis indicating the presence of silicon oxide (SiO2), potassium oxide (K2O), and calcium oxide (CaO). Fourier Transform Infrared (FTIR) spectroscopy highlighted diverse functional groups on PPAC's surface. CO2 adsorption tests were conducted at 27°C and 40°C with varying pressures on PPAC particles of 150µm and 845µm sizes. Results revealed that CO2 adsorption capacity increased with escalating pressures. Remarkably, at 27°C, PPAC exhibited superior performance than at 40°C, attributed to a higher-pressure drop enhancing the driving force for CO2 adsorption. Larger particles (845µm) demonstrated higher adsorption capacity due to increased surface area, enhanced pore accessibility, and faster mass transfer. The Response Surface Methodology (RSM) conducted gave 2FI model as the most representative of the design data and showed high accuracy (R2=0.9973) and low error metrics (MSE=0.01697, RMSE=0.130269, MAE=0.109, MAPE=2.7244). The Adeq Precision value of 76.26 validated the model's reliability. Optimization using RSM yielded optimal CO2 adsorption values (9.69 mmol/g) at 27°C and 100 bars. PPAC emerges as a promising solution for CO2 capture, offering valuable prospects in mitigating emissions and addressing climate change challenges.
