Note that while talking about costs, they never actually come out and say this will be a net savings, although that is in there:

• While these spending requirements are large and financing has yet to be established, many investments have positive return profiles (even independent of their role in avoiding rising physical risks) and should not be seen as merely costs.
• Technological innovation could reduce capital costs for net-zero technologies faster than expected.
• total cost of ownership for EVs is expected to be lower than ICE cars in most regions by 2025
• net-zero emissions can be achieved if and only if all energy and land-use systems that contribute to emissions are decarbonized -- MIT Take Note: Decarbonization is Required!!
