Sentences with phrase «about cement production»

(For fossil fuels, tax assessed preferably at the mine or well, to reduce paperwork and make enforcement efficient (as opposed to the exhaust pipe)-- but then a compensating credit for fossil C used in materials unlikely to be oxidized, etc, with compensating tariff / subsidy for trade between nations with differing policies; attempt at least approximate CO2eq tax for other sources so as to not distort the market (don't encourage too much deforestation for biofuels, don't forget about cement production, don't forget about cows, etc.)-RRB-.

Electricity production (including from coal) is the leading cause of green house gases right now, and the best estimate I can find about cement production puts it at about 5 % of the total man - made causes.

Short film about cement production and its effect on the environment.

Not exact matches

The nation's production of Portland cement — the most commonly produced cement type — amounted to about 80.4 million tons in 2015, according to the U.S. Geological Survey, or roughly the weight of about 90 Golden Gate Bridges or 12 Hoover Dams.

Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 27 billion tonnes per year (30 billion tons)-LSB-(Marland, et al., 2006)-- The reference gives the amount of released carbon (C), rather than CO2, through 2003.].

# 6 — «Since 1870 — with fossil fuel use, cement production, and land use combined — humans have put about 2,000 gigatons of CO2 in the atmosphere — that's two million million tons, and about 40 % has stayed there.»

Carbon dioxide emissions from fossil fuels and cement production — from 1750 to 2011 — was about 365 billion metric tonnes as carbon (GtC), with another 180 GtC from deforestation and agriculture.

The objective of this study was to compile data on the status of POPs emissions from the cement industry, to share state of the art knowledge about PCDD / F formation mechanisms in cement production processes and to show how it's possible to control and minimise PCDD / F emissions from cement kilns utilising integrated process optimisation, so called primary measures.

The Intergovernmental Panel on Climate Change in 2013 estimated that cumulative carbon dioxide emissions from fossil fuels and cement production — from 1750 to 2011 — was about 365 billion metric tonnes as carbon (GtC), with another 180 GtC from deforestation and agriculture.

The red numbers and arrows show the additional fluxes caused by human activities averaged over 2000 - 2009, which include emissions due to the burning of fossil fuels, cement production and land use change (in total about 9 PgC / year).

Past emissions of fossil fuels and cement production have likely contributed about three - quarters of the current RF, with the remainder caused by land use changes.

As I pointed out here, CAGR for CO2 emissions from coal, oil, natural gas, flaring, and cement production averaged 3.08 % for the period 2000 - 2010, peaking to 6 % in 2003 over 2002 (though there was no hysteria that time) and again in 2010 over 2009 (much unwarranted hysteria about a single year, even by professionals but perhaps overblown by the media as usual who may have been selective about who they quoted!).

When one complains about the environmental footprint of concrete, the main issue is usually the carbon footprint that comes from the production of cement.
