(SP/T) ERM PAPER - Material efficiency and climate mitigation
Introduction
The climate change mitigation today is a wide field, which it has to be since mostly all of human activity has some kind of impact to the environment. As of today the climate change is a growing subject and has really been taken into attention the last decade (source) as the climate change is becoming more and more noticeable by extreme weather, increasing temperatures, rising seal level and melting glaciers. One topic within climate change mitigation is how the extraction, use and growing scrap levels from different materials is having an impact to the environment. The growing demand of materials such as steel, concrete, aluminum, paper and plastic is forcing the production and extraction of these materials to grow and so does the emissions coming from these industries, together with activities using these materials such as transport. In this paper the role of material efficiency will be assessed by comparing the total greenhouse gas (GHG) emissions from material production …show more content…
The impact of recycling to the steel and aluminum industry has a slightly growing trend as the demand of materials increases. When assuming a more aluminum intensive scenario the emissions from aluminum industry increases and steel emissions are stagnating for the same scenarios. The total emissions from steel and aluminum industry due to recycling for the BAU is increasing from present level on about Gt CO2 equivalents per year to about 7.8 Gt CO2- eq per year. For the other scenarios the total emissions is lower due to recycling, stretching from 6.2 Gt to roughly 7.7
