Recycling of e-waste is an effective means for e-waste management. It has made great contribution to improving environmental benefits. This paper evaluates the emission reduction benefits and efficiency of e-waste recycling in China, using the direction distance function of DEA. Calculations show that from 2013 to 2017, the total emission reduction benefits of 29 provinces in China e-waste was 6.34 billion yuan, with an average emission reduction efficiency of 0.88. The emission reduction benefits of CO was 390 million tons, and the average emission reduction efficiency was only 0.82. The wastewater emission reduction benefits was 570 million yuan, with an average efficiency of 0.9. The emission reduction benefits of solid waste and SO are 5.37 billion yuan and 400 million yuan respectively, with the same emission reduction efficiency of 0.89. E-waste recycling in China still has huge potential for emission reduction.

Seawater electrolysis offers a promising pathway to generate green hydrogen, which is crucial for the net-zero emission targets. Indirect seawater electrolysis is severely limited by high energy demands and system complexity, while the direct seawater electrolysis bypasses pre-treatment, offering a simpler and more cost-effective solution. However, the chlorine evolution reaction and impurities in the seawater lead to severe corrosion and hinder electrolysis's efficiency.

Achieving sustainable development in livestock agriculture by balancing livestock production, reduction of greenhouse gas (GHG) emissions, and effective utilization of nitrogen nutrient has indeed been challenging. This study investigated the long-term effects of continuous cattle grazing, stocking rates, and fertilization regimens on methane (CH) emissions, soil microbial communities, and soil organic carbon (SOC) stocks in Bermudagrass pastures in East Texas, USA. Pastures were subjected to high or low stocking rates for over 50 years, with further subdivision based on fertilization: nitrogen-based fertilizer application or no fertilizer but with the growth of annual clover.

This study analyses the panel data for the 19 countries of West Africa and employed the Grossman health production function, which is estimated using the regression model with Driscoll Kraay standard error and the robustness of the result is evaluated using Common Correlated Mean Group estimator. Current health expenditure, per capita income, and C02 emissions are significantly associated with an improvement in life expectancy and a reduction in under-5 mortality. Per capita income and fossil fuel are associated with significant reductions in mortality from chronic conditions.

Accurate carbon accounting is essential for power generation enterprises to participate in carbon markets and implement carbon reduction strategies. However, due to excessive reliance on detailed energy data and manual calculations, carbon emission accounting in power generation enterprises suffers from low frequency, significant lag, and poor reliability. Some evidences suggest a strong correlation between internal carbon emissions and electricity consumption in power generation enterprises.
