De onderste grafiek van IEA is waarschijnlijk (wel of niet terecht) zonder de CO2-uitstoot die bij het gebruik van bio-energie vrijkomt (BECCS gebeurt momenteel nog erg weinig). Op de website van het IEA lees ik het volgende:
Bioenergy is a source of energy from the organic material that makes up plants, known as biomass. Biomass contains carbon absorbed by plants through photosynthesis. When this biomass is used to produce energy, the carbon is released during combustion and simply returns to the atmosphere, making modern bioenergy a promising near zero-emission fuel.
Modern bioenergy is the largest source of renewable energy globally today, accounting for 55% of renewable energy and over 6% of global energy supply. The Net Zero Emissions by 2050 (NZE) Scenario sees a rapid increase in the use of bioenergy to displace fossil fuels by 2030. Use of modern bioenergy has increased on average by about 3% per year between 2010 and 2022 and is on an upward trend. More efforts are needed to accelerate modern bioenergy deployment to get on track with the NZE Scenario, which requires deployment to increase by 8% per year between 2022 and 2030, while simultaneously ensuring that bioenergy production does not incur negative social and environmental consequences.

De vraag naar en productie van biobrandstoffen groeit snel en moet een belangrijke rol spelen in net zero (ook in de EU). Wat zal de (wereldwijde) ecologische impact zijn bij een alsmaar stijgende vraag.
