With CAIT WRI data for those countries which submitted quantifiable CO2 emission caps under the Copenhagen Agreement, this note supports the existence of a long run relationship between CO2 emissions and GDP in 11 of the 26 countries in our sample over the period 1980-2008. However, the...

Cement industry is among the most energy-intensive economic sectors. Moreover, significant amounts of carbon dioxide are released to the atmosphere as a result of Portland clinker combustion process, where carbonates (limestone, marl) are the main raw materials applied. To offset the harmful...
