Measurement Issues • Pressure • Consumption measures may not be appropriate for poorest countries of the world • Emissions measures are typically not available for poorest countries of the world • State • Narrowly constructed measures of change in natural capital are not comparative because countries have different endowments • Difficult to establish causality with exposure/impact measures • Exposure/impact measures are typically not available for poorest countries of the word
Measurement Issues • Response • It’s one thing to pass legislation and create regulatory regimes, quite another to implement and enforce them • Process issues are already addressed by existing MCC measures (e.g., voice and accountability, political rights, civil liberties) • It is possible to over regulate to the point of economic burden
Possible Ways Forward • Policy effectiveness measures • Measure degree to which policies achieve desired outcomes • Examples: • Rate of land use change in protected areas • Decline in toxic reductions as result of TRI style “freedom of information” policy • Highly aggregated measures of change in natural capital • Change in net primary productivity • Net annual CO2 flux into the atmosphere attributable to anthropogenic land use/cover change • Green National Accounts (e.g., adjusted net savings)
Net annual CO2 flux into the atmosphere attributable to anthropogenic land use/cover change • Accounts for: • tropical, temperate zone, and boreal deforestation; • cultivation of mid-latitude grassland soils; • accumulations of carbon in wood products and woody debris; • losses of carbon from oxidation of wood products, woody debris, and soil organic matter; and, • the accumulation of carbon in forests recovering from harvest and in the fallows of shifting cultivation. • Accounting based approach uses national estimates of conversion rates and emissions factors. • Issues: • Annual time series stops in 2000. • Needs to be normalized by endowment.
