Not exact matches
After doing my research, shown above (which I pretend support my claim, even though I said «this does not support my claim»), I see that
cement production is not in the very top of CO2 emission causes (in comparison to others named above), but is in fact already one of the top in regards to manufacturing, materials, and minerals — which, while not as detrimental as I had believed, is still a pretty remarkable feat, especially whenever you look at the
increase in effects in recent years and take in the knowledge that it's only going to get worse.
Or the evidence tying that
increase to fossil fuel use,
production of
cement and other human activities?
New technologies have enabled
increased use of clinker substitutes and alternative fuels in
cement production, leading to significant direct (e.g. from limestone decarbonisation) CO2 emissions reductions.
A key finding for all is that realization of the 2 Degree Celsius Scenario (2DS) implies a significant reduction of the global direct CO2 emissions by 24 % compared to current levels by 2050, considering the expected
increase in global
cement production.
As global population rises and more people move into cities, global
cement production is set to grow by 12 to 23 % by 2050, and despite
increasing efficiencies, direct carbon emissions from the
cement industry are expected to
increase by 4 % globally by 2050 under the IEA Reference Technology Scenario (RTS).
Most industry sector scenarios indicate that demand for materials (steel,
cement, etc.) will
increase by between 45 % to 60 % by 2050 relative to 2010
production levels.
Given that this would require a massive
increase in concrete (which has higher reflectivity but produces a great deal of CO2 in the
production of the concrete's
cement) and a lot of new paint and light - colored gravel for commercial roofing, the economic costs would be significant.
A few industries will see larger
increases, but most of these are bulk - material industries (such as
cement), the
production of which is highly local and not likely to move overseas.
From 1999 to 2005, global emissions from fossil fuel and
cement production increased at a rate of roughly 3 % yr — 1.
