resulting in a 90% emission reduction compared to hydrogen from SMR. Tightening the emission cap from 3-cap to 1-cap is associated with an average LCOH increment of 4%, facilitating a further 6% reduction in emissions. When the cap is further tightened, decreasing from 1- to 0.5-...
Tier 1 suppliers might be best positioned to encourage Tier 2 suppliers to reduce emissions, since their relationship as end customers may give them more leverage. While it may seem difficult for suppliers to cooperate along the value chain, examples of past collaborations exist. For instance, ...
Various strategies such as the capture and storage of CO2 in geological formations can be adopted to minimise CO2 emissions into the atmosphere. The techniques used to store CO2 underground include CO2 injection into deep aquifers [2], CO2 injection into depleted gas and oil reservoirs [3], and...
Did this lead to higher volcanic CO2 emissions and therefore greater warming16,17? Does the climate system respond to CO2 precipitation in the oceanic crust as a sink or source of carbon, and how is this process modulated by plate spreading rates, ocean bottom temperatures and subduction ...
While grocers’ direct contribution to these emissions is relatively low, the grocery sector has a unique opportunity to become the driving force for decarbonization of the entire food system (see sidebar “Building a sustainable food system”). Moreover, decarbonization presents an ...
Likewise, using one ton of cullet reduces CO2 emissions by 300 kg due to the decreased energy consumption. Thus, glazing made of cullet and other examples of recycled materials should be a strong consideration for architects working toward decarbonization....

in order to find out how much of the carbon dissolved from each subducting slab ultimately gets recycled to the atmosphere. While the quantification of CO2outputs is hindered by the difficulties in sampling volcanic emissions on remote or small volcanoes, a recent review54suggests that much of CO2...
Carbon capture and storage is another approach separating CO2emissions from the process, where the CO2is compressed, transported to a suitable geological storage location, and then safely injected. The process must be safe when transported using pipelines and shipping. It is known that suitable storag...
Based on the synchronous variations of both development and emissions, we hypothesize that some intrinsic links between cities and their carbon footprints could exist. Along with a decreasing increase in carbon emissions, some nations have almost finished urbanizing in the last few decades. With this...
