The industrial processes and product use (IPPU) sector’s emissions increased from 0.021 MtCO₂e/yr in 1990 to 0.401 MtCO₂e/yr in 2016.
Overall, the sector contributes very little – just 2% – to Namibia’s cumulative emissions and even this has fluctuated significantly over time as different industries have begun and ended. Particularly relevant would be the emission increases in 2003 due to the commencement of zinc production, in 2011 when cement production begun, and a decrease in 2016 when lime production ceased.,
The main drivers of emissions In the IPPU sector are the metal, mining, and construction industries. The industrial processes sector does not feature strongly in the country’s mitigation plans given its small overall contribution to total emissions.
Across all analysed 1.5°C pathways, industrial activity increases to 2050 with much of this increase being met with electrified processes. For example, in the ‘SSP1 High CDR reliance’ pathway, by 2050 electricity makes up 67% of the fuel mix, with biomass making up most of the rest.
