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

Timely and quantitatively evaluating regional eco-environmental quality (EEQ) is of great significance for realizing sustainable development goals. Especially cloudy areas, it was a challenge to construct EEQ dataset with high resolution. However, existing studies failed consider the influence land surface season elements in EEQ. Therefore, this study aimed promote an accurate EEQ-evaluating framework areas. Zhaotong city, typical karst region, chosen as area. First, we integrated multi-source spatiotemporal datasets constructed novel comprehensive evaluation index (ECEI) assess its from 2000 2020. Next, standard deviation ellipse (SDE) trend analysis methods were applied investigate EEQ’s change trends. Finally, ecological (EI) values different years calculated validate effectivity ECEI. The main findings follows: (1) showed upward-fluctuating (0.0058 a−1), average ECEI 0.729, 0.693, 0.722, 0.749, 0.730. (2) spatial distribution pattern north low south, Zhaoyang district having lowest value. (3) From 2020, major axis moved northeast city θ SDE changing 57.06° 62.90°, thus, indicating improvement northeastern regions’ (4) coefficients determinant (R2) between EI 0.84, which higher than that EI–RSEI (R2 = 0.56). This indicated our promoted could acquire more results provide suggestions relevant policymakers.

In recent years, urban waterlogging disasters have become increasingly prominent. Physically based simulation models require considerable computational time. Therefore, rapid and accurate prediction of pluvial floods are important for disaster prevention mitigation. For this purpose, we explored an method on a long short-term memory neural network model that integrates attention mechanism 1D convolutional (1DCNN–LSTM–Attention), using the diversion Jinshui River in Zhengzhou, China, as case study. method, 1DCNN is responsible extracting features from monitoring data, LSTM capable learning time-series data more effectively, Attention highlights impact input effectiveness. The results indicated following: (1) exhibited good accuracy. Pearson correlation coefficient exceeded 0.95. It was 50–100 times faster than InfoWorks ICM model. (2) Diversion pipelines can meet design flood standard 200-year return period, aligning with expected engineering objectives. (3) channel significantly reduced extent inundation. Under 30-year period rainfall scenario, maximum inundation area decreased by 1.46 km2, approximately equivalent to 205 international soccer fields.
