TL;DR: In this paper, the authors analyzed a representative set of countries, including Australia, Brazil, China, Germany, India, Iran, Italy, Japan, Portugal, South Africa, Spain, United Kingdom, and the United States of America, to identify the ones with the best investment opportunities considering the new regulations.

TL;DR: In this paper, the authors compared the greenhouse gas emissions, energy use, water use, and potential environmental toxicity of conventional (Conv), glass powder (GP), and alkali-activated slag (AAS) concrete and mortar and found that compared to a 35-MPa Conv concrete, a 35MPa GP concrete has, on average, 19% lower GHGs, 17% less energy, 14% less water, and 14-21% lower environmental toxicity.

TL;DR: In this paper, the economic profitability of different regions considering the solar radiation levels, savings in self-consumption, cash flows from injecting power into the grid and local prices for installations is analyzed.

TL;DR: In this paper, the authors systematically evaluated uncertainties that result from considering different LCIA methods; cases from the US LCI and the ecoinvent database were used to demonstrate the uncertainties and showed that the discrepancies of the total impact results were caused by differences in 1) the total emission values included in the inventory; 2) the coverages of substances in methods, and 3) the differences in the characterization factor values of the substances.

TL;DR: Improved uncertainty assessment supports various types of decisions, such as product comparisons, hotspot analysis, and overall energy analyses, and can be extended to additional types of flows, beyond energy, and to process-matrix-based LCA models.
