The challenge of climate change demands a response from all sectors of the economy. Importantly, action on the part of individuals will be required if greenhouse gas (GHG) emissions are to be cut to the levels necessary to avoid the worst

To increase communities involvement in mitigating climate change, support from local governments is very crucial not only as facilitator but also as finance providers. Local Government in developing countries can create umbrella program for communities througout the country to implement small scale mitigation project activities, such as Programmatic CDM.

At the simplest level, weather is what is happening to the atmosphere at any given time. Climate is a measure of what to expect in any month, season or year, and is arrived at using statistics built up from observations over many years.

The climate policy debate has advanced from science to economics, with a growing focus on creating carbon markets and getting the prices right. This is necessary but far from sufficient for an effective and equitable response to the climate challenge.
