In 2007, the UNFCCC Secretariat prepared a report on
"Investment and Financial Flows to Address Climate
Change".11 The report covers mitigation and adaptation in
various sectors over the period to 2030. The report defines
an investment as the initial (capital) cost of a new physical
asset with a life of more than one year, such as the capital
cost of a gas-fired generating unit or a water supply
system. A financial flow is an ongoing expenditure related
to climate change mitigation or adaptation that docs not
involve physical assets, such as research or health care.
These investment and financial flows arc NOT the same as
the cost of addressing climate change; changes to the
operating costs of investments arc not considered nor arc
damages due to climate change estimated.
