ASEAN: A roadmap to Euro VI

摘要

When it comes to heat-trapping greenhouse gases,carbon dioxide(CO2) is public enemy number one.CO2 is widely considered the chief perpetrator in a well-publicised increase in our global temperature.Consequently,a substantial global effort is focused on reversing atmospheric CO2 levels to avert the worst impacts of future climate change.Unfortunately,CO2 has an extremely long atmospheric lifetime.Abrupt changes to our CO2 inducing practices are not going to magically alleviate the predicament we find ourselves in.It can take several decades for CO2 concentrations to begin to stabilise,even after we lower our emissions levels.The good news is,while CO2 hangs around for years,there is an opportunity in the immediate term to impact global temperature increases.
