Operating from within the ADB's office of the president in the Philippines, Evans will function as a climate envoy and provide broad oversight and guidance for ADB's climate operations.
The ADB says this role would include optimising climate finance scale and impact, mobilising new and additional technical and financial resources, strengthening ADB's external climate partnerships and engagement with international climate agreements and initiatives and reinforcing capacity development for climate change operations.
"ADB is in a particularly unique position to support bold, decisive action driven by close partnerships with and tailored to meet the near and long-term needs of our developing member countries," Evans said.
"It is critical that we act together and act now, with speed, innovation, and scale, to respond to the central development issue facing our region."
The ADB says that over the past year it had raised its ambition to deliver climate finance to its developing member countries to $100 billion (about K352 billion) from 2019 to 2030, adopted a new energy policy that formalised ADB's practice of not financing new coal-fired power and heating plants, and committed to aligning its operations with the goals of the Paris Agreement.
