The measurement of the embodied carbon emissions of goods tells us what greenhouse gas emissions are generated during the production and transportation of those goods. This achieves two main things. Firstly, it allows producers to understand where their emissions are coming from, and so reduce them. Secondly, it opens the door to putting a price on those emissions, thus incentivising producers to reduce them. But, as Max Gruenig at E3G explains, … [Read more...]
Concrete: 8% of global emissions and rising. Which innovations can achieve net zero by 2050?
Concrete manufacture is responsible for 8% of global carbon emissions, with the ingredient “clinker” accounting for most of it. Global demand for cement (which hardens into concrete) is expected to increase 48% from 4.2bn to 6.2bn tons by 2050, mainly driven by developing nations. China used more concrete between 2011 and 2013 than the United States did in the entire 20th century. Ben Skinner and Radhika Lalit at RMI look at the materials and … [Read more...]
10 Carbon Capture methods compared: costs, scalability, permanence, cleanness
We need to understand carbon capture, storage and utilisation (CCUS) better. To do so, this article looks at 10 methods and estimates how much CO2 each will take out of the atmosphere by 2050, and the cost per tonne. In their list the authors, Ella Adlen and Cameron Hepburn at the University of Oxford, cover the industrial (e.g. CO2-EOR, synfuels) to the biological (e.g. forestry, soil carbon sequestration). They say there are six that can be … [Read more...]
