Reinvesting in wind, solar, electrification avoids higher carbon fuels and deforestation for firewood. Reinvesting in timber value chains maximizes CO2…

Polyester: production process?

Polyester is the most produced textile fiber on planet Earth. Of the world’s 8GTpa of oil and gas production, 80MTpa, or 1% ends up as PET, via eleven chemical processing stages that span naphtha-reforming, BTX separation into paraxylene, oxidation to PTA, plus ethane cracking, ethylene oxide and ethylene glycol. This data file covers the polyester…

Carbon markets: by category over time?

This data-file quantifies global carbon markets by category over time, including the EU ETS as an example of a compliance market, RECs, CCS and VERRA-certified “carbon credits”, across categories such as REDD, reforestation and other “carbon offsets”. We also draw analogies with charitable giving and forecast carbon markets out to 2050.
