Asset owners alliance offers net-zero protocol Getty Images A protocol to help asset owners set decarbonization targets was released Thursday by the U.N.-convened Net-Zero Asset Owner Alliance. The Inaugural 2025 Target Setting Protocol is designed to complement individual decarbonization targets for achieving net-zero emissions by 2025. Asset owners are setting their own targets for Scope 3 emissions, also referred to as portfolio emissions, that are called for under the Paris Agreement. Scope 3 emissions targets are not expected to be set until data become more reliable, but the alliance requires members to publish interim targets every five years, in line with a similar Paris Agreement requirement for signatories. The next updated emissions reduction plans are due in 2025.
