Concrete as a carbon store
Berlin, Germany (SPX) Jan 22, 2025 In order to lower atmospheric CO2 levels to the target set in 1988 - 350 ppm (parts per million) - an estimated 400 billion tons of carbon must be removed from the atmosphere. This amounts to approximately 1,500 billion tons of CO2. Empa researchers have explored a novel approach, suggesting that this excess carbon could be stored in building materials such as concrete by the middle of the next century. "These calculations are based on the assumption that sufficient renewable energy will be available af ... read more |

Tourism among leading contributors to global carbon emissions
Los Angeles CA (SPX) Dec 11, 2024 A study led by the University of Queensland reveals that greenhouse gas emissions from tourism are growing over twice as fast as emissions from the rest of the global economy. Associate Professor Ya-Yen Sun of UQ's Business School highlighted that the surge in travel demand has pushed tourism's carbon emissions to represent 9% of global totals. "Without urgent interventions in the global tourism industry, we anticipate annual increases in emissions of 3 to 4% meaning they will double every 2 ... read more
