(How to Solve) Indirect Land Use Change from biofuels

23 maart 2017
bijeenkomst werkgroep Grondstoffen
presentatie Carlo Hamelinck – Ecofys

Tijdens de bijeenkomst van de werkgroep Grondstoffen gaf Carlo Hamelinck (Associate Director van Ecofys) een toelichting op de resultaten van de Globiom-studie. Deze studie is opgesteld in opdracht van de Europese Commissie om inzicht te krijgen over de indirecte effecten van landgebruikverandering als gevolg van de inzet van biobrandstoffen.

In de presentatie licht Hamelinck de achtergronden en de resultaten van de Globiom-studie toe. Hij waarschuwt om zorgvuldigheid in acht te nemen bij het interpreteren van de resultaten van de studie:

  • “ILUC factor is only for additional biofuels compared to 2010 level
    • De often cited Transport and Environment (NGO) interpretation is incorrect
    • ILUC factors do not add to direct emissions for all biofuels
    • (Moreover, observed direct emissions much better than RED typical)
  • Biofuels produced from crops under set-aside regime ILUC free
  • Results for individual crop-fuel combinations are for a 1% increase from 2010
  • Smaller increases would result in lower ILUC values (non-linearity)
  • ILUC amortised over 20 years – after 20 years much lower value
  • Sustainable biofuels are essential for sustainable transport (next to other solutions)”

Hamelinck sluit zijn presentatie af met enkele perspectieven:

  • “Biofuels are not automatically good or bad
  • The potential for sustainable biofuels can be very large
    • This requires improvements in agricultural practice and system
  • In long run, bioenergy and -materials have low greenhouse gas emissions
    • ILUC pays back: much smaller or even zero after 20 years
    • Fossil fuels never pay back – instead, emissions increase
  • Deforestation & peatland drainage will not stop in absence of biofuels
    • Under global 1.5C scenario these practices will stop à ILUC disappears
  • Produce biofuels feedstock without ILUC
    • Increase yields above baseline (especially relevant for “food crops”)
      • Developed countries: innovations: precision farming, multi-cropping
      • Developing countries: bridge yield gaps: access to means, know-how & market
    • Production on unused / abandoned land (direct & good Land Use Change)
    • Cellulose feedstocks, sustainable fraction of residues, and true wastes
  • Any ILUC mitigation measure should be credible and verifiable”
