What measure can be taken to reduce CO₂ emission?

The green house effect of CO2 has attracted attention not only of expert and politicians, the public pressure (mostly the news media) have made the reduction of CO2 emission an international priority. The United Nations Panel on Climate Change made several recommendations regarding CO2.

• use natural gas as fuel rather than coal or oil
• use solar or nuclear energy instead of fossil fuels for electricity generation
• reduce rate of deforestation
• limit use of automobiles

Well, what can be done at a personal level, as a community, and as a country requires the determination of individuals. This is a challenge for us all especially engineers, because they are at the forefront of many industries. We face many front for a solution to the problem of carbon dioxide emission.
