This minimizes the entire life cycle carbon footprint of a product, providing a long-term emissions reduction solution, rather than looking at just one part of the cycle such as airfreight.

Abstract: This paper calculates the life cycle carbon emissions of a residential building in hot summer and warm winter area, and analyzes the building life cycle impact on carbon emissions targets.

The three most important nutrient recycles are the nitrogen cycle, the carbon cycle and the one we are going to talk about today, the Phosphorus cycle.
