Pareto criterion / Pareto optimum
A requirement or status that an individuals welfare could not be further improved without making others in the society worse off.
The opportunity that one individuals welfare can be improved without making the welfare of the rest of society worse off.
Among the six greenhouse gases to be abated under the Kyoto Protocol. These are by-products of aluminium smelting and uranium enrichment. They also replace chlorofluorocarbons in manufacturing semiconductors. The Global Warming Potential of PFCs is 65009200 times that of carbon dioxide.
Policies and Measures (PAMs)
In United Nations Framework Convention on Climate Change parlance, policies are actions that can be taken and/or mandated by a governmentoften in conjunction with business and industry within its own country, as well as with other countriesto accelerate the application and use of measures to curb greenhouse gas emissions. Measures are technologies, processes, and practices used to implement policies, which, if employed, would reduce greenhouse gas emissions below anticipated future levels. Examples might include carbon or other energy taxes, standardized fuel efficiency standards for automobiles, etc. Common and co-ordinated or harmonized policies refer to those adopted jointly by Parties.
See Purchasing Power Parity. It also stands for polluter-pays-principle.
A provision under Article 3 of the United Nations Framework Convention on Climate Change, stipulating that the Parties should take precautionary measures to anticipate, prevent or minimize the causes of climate change and mitigate its adverse effects. Where there are threats of serious or irreversible damage, lack of full scientific certainty should not be used as a reason for postponing such measures, taking into account that policies and measures to deal with climate change should be cost-effective so as to ensure global benefits at the lowest possible cost.
Present value cost
The sum of all costs over all time periods, with future costs discounted.
The responsiveness of demand to the cost for a good or service; specifically, the percentage change in the quantity consumed of a good or service for a 1% change in the price for that good or service.
Energy embodied in natural resources (e.g., coal, crude oil, sunlight, uranium) that has not undergone any anthropogenic conversion or transformation.
Primary market and secondary market trading
In commodities and financial exchanges, buyers and sellers who trade directly with each other constitute the primary market, while buying and selling through the exchange facilities represent the secondary market.
Categories of costs influencing an individuals decision-making are referred to as private costs. See also social cost, external cost, and total cost.
Returns beyond the cost of production that provide compensation for owners of skills or assets that are scarce (e.g., agriculturally productive land). See also consumer surplus.
Project costs are all the financial costs of a project such as capital, labour, and operating costs.
Purchasing Power Parity (PPP)
Estimates of Gross Domestic Product based on the purchasing power of currencies rather than on current exchange rates. Such estimates are a blend of extrapolated and regression-based numbers, using the results of the International Comparison Program. PPP estimates tend to lower per capita Gross Domestic Products in industrialized countries and raise per capita Gross Domestic Products in developing countries. PPP is also an acronym for polluter-pays-principle.
