This briefing by the Chair of the clean development mechanism (CDM) Executive Board, provided Parties with
practical information about how certified emission reductions (CERs) generated by CDM projects can be used to
close the pre-2020 ambition gap. At the 2013 UN Climate Change Conference in Warsaw, a decision was taken to
"promote the voluntary cancellation of CERs, without double counting, as a means of closing the pre-2020
ambition gap." (1/CP.19, para 5(c)).
Based on a 2012 study, a conservative estimate of the pre-2020 ambition gap, or the amount of emissions that
would need to be further reduced to limit global warming to two degrees Celsius by 2100, is roughly 20
billion tonnes. Recent estimates on available CDM offset credits, so called CERs, indicate that up to 40 per
cent of the emissions gap could be closed through the use of CERs.
The opportunities, challenges and costs for Parties to use CERs in this context were discussed, as were
the practical aspects of implementing the mandate. The briefing also shared some examples of CERs being
used as a means to support carbon neutrality initiatives.
