Paris Agreement requires substantial, broad, and sustained engagements
beyond COVID-19 recovery packages
Abstract
It has been claimed that COVID-19 public stimulus packages could be
sufficient to meet the short-term energy investment needs to leverage a
shift toward a pathway consistent with the 1.5 °C target of the Paris
Agreement. Here we provide complementary perspectives to reiterate that
substantial, broad, and sustained engagements beyond recovery packages
will be needed for achieving the Paris Agreement long-term targets.
Low-carbon investments will need to scale up and persist over the next
several decades following short-term stimulus packages. The required
total energy investments in the real world can be larger than the
currently available estimates from Integrated Assessment Models (IAMs).
Existing databases from IAMs are not sufficient for analyzing the effect
of public spending on emission reduction. To inform what role COVID-19
stimulus packages and public investments may play for reaching the Paris
Agreement targets, explicit modelling of such policies is required.
