It also presents objectives for its four strategic sustainability pillars: climate & energy, circular economy, environment and community. In 2018, LafargeHolcim's net CO2 emissions per tonne of cementitious material decreased to 576 kg CO2/ tonne, a 1% reduction from 2017 and equal to a 25% reduction compared with 1990 emissions. This exceeds the company's year-on-year reduction objective and positions it to deliver on a new carbon reduction target of 520 kg CO2/tonne by 2030. The improve- ment was achieved by reducing the clinker-to-cement ratio and consuming less energy per tonne of cement, mostly by using alternative fuels and improv- ing process efficiency. Last year, the company treated 52 mil- lion tonnes of waste, a 6% increase from 2017. More than 11 million tonnes – an increase of 10% over 2017 – were used by Geocycle, the company's global waste management business, as a fuel for kilns or as alternative raw mate- rials using co-processing technology. Depending on the waste regulation in a country and the development of its waste market, LafargeHolcim can reach a fossil fuel replacement rate of more than 90 percent. In addition, the company recovered an additional 41 million tonnes of waste, mainly byproducts from other industries, such as slag from the steel industry and fly ash from power gen- eration, to replace clinker in the final cement product. Reducing the clinker content in cement allows LafargeHol- cim to limit the CO2-intensity of its cement production. In the report, the company said it has reduced water withdrawal in cement plants by around 19% over the last four years. LafargeHolcim will now shift its focus to consider its total impact on water resources in the communi- ties where it operates, particularly in water-scarce areas. In consequence, the company will revise its ambitions to reflect water impact, which it intends to reduce by focusing on the most vul- nerable areas of operation. Lastly, LafargeHolcim reports 2.9 million people benefited from its com- munity programs worldwide in 2018 – with over 15 million having benefited over the last four years. MSHA Issues Serious Accident Alert The Mine Safety and Health Administration (MSHA) issued the following Serious Accident Alert. On May 7, 2019, a miner suffered burns to his body when superheated gases carrying hot, fine, alkaline particles were forcefully expelled through an open process vessel door. The victim was on a platform 5-6 ft. above other miners who were setting off a Cardox charge to free a blockage in the vessel. He opened the door around the same time they set off the charge. MSHA recommends the following best practices to avoid this type of accident: • Wear appropriate protective clothing when working around superheated materials. • Develop and follow safe work procedures for performing hazardous tasks. • Ensure that equipment operators establish good commu- nications between themselves and other miners that may be working around or near their work areas. • Stay out of the line of fire when unchoking vessels, chutes and hoppers. • Task train all persons to recognize all potential hazardous conditions and ensure they understand safe job procedures for elimination of the hazards. HeidelbergCement Receives Approval for Science-Based Emissions Targets Following a thorough validation procedure, Heidelberg- Cement's carbon dioxide emissions reduction targets for 2030 have been successfully assessed against the Science Based Targets initiative's (SBTi) criteria. This makes Hei- delbergCement the first company in the cement sector, and one of about 200 companies worldwide, to have approved science-based targets. Based on bottom-up measures at plant and product levels, the reduction strategy includes improving energy efficiency
