Emissivity of main building materials – what the future brings?
Języki publikacji
Abstrakty
Przemysł stanowi prawie 40% globalnego zużycia energii i prawie jedną czwartą bezpośrednich emisji dwutlenku węgla (CO2). Produkcja stali, cementu i aluminium jest odpowiedzialna za jedną czwartą tej energii i połowę bezpośrednich emisji CO2. W celu zmniejszenia globalnej emisji CO2, efektem którego będzie zahamowanie procesu globalnego ocieplenia, Międzynarodowa Agencja Energetyczna (IEA) zaproponowała scenariusze, które nawet przy gwałtownym wzroście zapotrzebowania na materiały do 2060 r. mogą spowodować redukcję emisji dla stali o 70%, cementu – o 20%, a aluminium – o 30%. Zakłada ona zmniejszenie globalnej emisji dwutlenku węgla w sektorze energetycznym o prawie 75%, redukcję ilości materiałów oraz poprawę wykorzystania materiałów w produktach finalnych, w tym również w sektorze budowlanym. Artykuł bazuje na danych zawartych w raportach Międzynarodowej Agencji Energetycznej z 2019 r.
Industry accounts for almost 40% of global energy consumption and almost a quarter of direct CO2 emissions. Steel, cement and aluminium production alone represents 12% of global energy consumption and 13% of global CO2 emissions. By keeping emissions at the current level, we will use the remaining 2050 carbon budget in 12 years. In order to reduce carbon dioxide (CO2) emissions and thereby stop the global warming process, the International Energy Agency (IEA) has proposed scenarios that can lead to the reduction of emissions by 2060: for steel by 70%, for cement – by 20%, and for aluminium – by 30 even under the assumption of a rapid increase in demand for these materials. The Agency assumes a decrease in global CO2 emissions in the energy sector by almost 75%, a reduction of materials consumption and an improvement in the use of materials in final products, including the construction sector. The article is based on the data included in the reports published by the International Energy Agency in 2019.
