In the context of C02 emission and Global Warming, what is the name of a market driven device under the UNFCC that allows developing countries to get funds/incentives from the developed countries to adopt, better technologies that reduce greenhouse gas emissions

Explanation

Option 1: `Carbon Footprint` refers to the total emissions of CO2 (Carbon Dioxide) and other greenhouse gases that an individual, organization, event, product, or country produces directly or indirectly. It`s a measure, not a market-driven device to incentivize emission reduction. Option 2: `Carbon Credit Rating` does not exist in the context of CO2 emissions and global warming, so it`s not a relevant answer. Option 3: The `Clean Development Mechanism` (CDM) is the correct answer. It is a device under the UNFCCC (United Nations Framework Convention on Climate Change). The CDM allows developing countries to generate “certified emission reductions” (CERs), from emission savings from CDM projects, and these CERs can be traded and sold, providing a financial incentive for emission reduction. Option 4: `Emission Reduction Norm` generally refers to a standard or guideline to reduce pollutant emissions, but it`s not a market-driven mechanism that allows funding transfer from developed to developing countries to adopt better technologies.
