The Climate Impact of Wilmar’s “No Deforestation, No Peat, No Exploitation” Policy

By Climate Advisers

Preliminary analysis suggests that Wilmar’s new commitment will eliminate more than 1.5Gt CO2 emissions total between now and 2020 — and perhaps substantially more.

This estimate is based on a conservative analysis of the policy’s impacts only on the development of peat-swamp forests in Malaysia, Borneo, and Sumatra, based on carbon emissions estimates in Koh et al.

Let’s assume that emissions are equal across the 45% of palm oil supply traded by Wilmar, the more than 80% of supply traded by companies that sell to Wilmar, and the remaining suppliers. Let’s further assume that peatland clearing for palm oil declines rapidly for the 45% of the market flowing through Wilmar (by 20% per year, reaching zero in 2018); declines somewhat for other supplies by the same companies (declining 5% a year, down to 70% of current rate in 2020); and holds steady for the remainder of the market.

If peat emissions are only considered for the 5 years following conversion, this scenario yields a reduction of palm oil development emissions reaching 325 MMt/year in 2020 and totaling more than 1.5 Gt CO2e from 2014 through 2020.

The true reductions could be significantly higher — because peatlands continue to emit for far longer than the 5 years included in this analysis; because palm oil expansion is not limited to just these areas nor to just peatlands; because the analysis doesn’t consider whether the policy will reduce speculative clearing for oil palm; and because the analysis has assumed that emissions from oil palm development would be flat at current levels rather than continue to grow, as they have in the past decade.
