Achieving European Green Deal (EGD) targets for carbon removal and ecological restoration would reduce agricultural and forestry production within the European Union yet simultaneously extend ecosystem impacts elsewhere. Here we quantify such spillover impacts by coupling an extended multi-regional input–output analysis with an agro-ecological zones model. We find that EGD’s agricultural and forestry targets set for 2030 could result in a 23.9 Mha increase in demand for agricultural land outside the European Union, which in turn would lead to an increase in land-use-related carbon emissions by 758.9 MtCO2-equivalent (244.8% of EGD’s carbon removal target in the land, land-use-change and forestry sectors) and a biodiversity loss of 3.86 million mean species abundance loss. Such spillover impacts far exceed the ecological benefits from EGD conservation-based import policies, such as promoting deforestation-free products and phasing out food-based biofuel. We then propose three options beyond the primary targets of the EGD with the aim to mitigate such spillover impacts. The assessment of these options reveals the critical role of reducing meat and dairy consumption, highlighting the impact of consumer behaviour on environmental outcomes. This raises questions about public awareness, willingness to change diets and the role of policy in influencing consumer behaviours. Achieving European Green Deal targets may benefit the European Union ecologically but increase global environmental impacts. This study quantifies such external impacts and suggests ways to minimize them

The role of China is increasingly pivotal in climate change mitigation, and the formulation of energy conservation and emission reduction policies requires city-level information. The effectiveness of national policy implementation is contingent upon the support and involvement of local governments. Accurate data on final energy consumption is vital to formulate and implement city-level energy transitions and energy conservation and emission reduction policies. However, there is a dearth of data sources pertaining to China’s city-level final energy consumption. To address these gaps, we developed computational modeling techniques along with top-down and downscaling methods to estimate China’s city-level final energy consumption. In this way, we compiled a final energy consumption inventory for 331 Chinese cities from 2005 to 2021, covering seven economic sectors, 30 fossil fuels, and four clean power sources. Moreover, we discussed the validity of the estimation results from multiple perspectives to enhance estimation accuracy. This dataset can be utilized for analysis in various cutting-edge research fields such as energy transition dynamics, transition risk management strategies, and policy formulation processes.

AbstractThe renewal and expansion of the built environment within the context of rapid urbanization are imposing new benchmarks for resource management, particularly concerning the billions of tons of consumption and waste generation of concrete materials. The commercialization of carbonation in cementitious materials is underway, opening up possibilities for nitrogenation that has been well documented in recent experimental studies.

AbstractAchieving low-carbon development of the cement industry in the developing countries is fundamental to global emissions abatement, considering the local construction industry’s rapid growth. However, there is currently a lack of systematic and accurate accounting and projection of cement emissions in developing countries, which are characterized with lower basic economic country condition.
