Lenovo helps you offset carbon over average 5-years lifecycle of your device at the point of purchase.
The project adopts a two-phase absorbent with low energy consumption to capture CO2, and the regeneration energy consumption of such absorbent is less than 2.4 gigajoule per tonne, reaching the advanced level globally. The captured CO2 is then used to produce industrial products with wide applicatio...

Moreover, the purity level of injected CO2 is 99.9%, and its moisture is less than 100 ppm. In different time intervals (2, 5, 9, 18 and 37 weeks), the solid and liquid samples were collected after cooling and releasing the pressure in the reaction cell since a drain valve for ...
occupying about 64% of the Earth’s surface13; these lithologies have OCpetromass to mass concentration (denoted as [OCpetro]) ratios of about 0.25% to more than 1.0%, whereas igneous rocks have much lower values, effectively 0%, or in the case of some marine basalts, less than 0.1% ...
If people find that online collaboration is less expensive and more efficient than meeting in the field during this period, then this may become a powerful driver for carbon emissions reduction. Conclusion This paper conducted a study of the carbon emission intensity in China from 1990 to 2017. ...
“This solution uses much less concrete than conventional buildings, and carbon emissions in the construction phase could be offset by more than 90 percent,” he said. Williamson made the remarks as he addressed a session organized by the Global Alliance for Buildings and Construction (GlobalABC)...
