How to make money and prevent climate change in the process!

An intriguing headline in the metro page of HT today caught my eye - "Climate change on priority list, civic body plans fund". The article quotes the Mayor Kanwar Sen: "Currently in the MCD budget, there are hardly any funds earmarked for dealing with climate change, an issue that needs due priority. We are planning to get a separate head for funds for this purpose". What is on Sen's mind? Environment friendly projects that earn carbon credits, it seems, and restoring Yamuna to its "original healthy state" with Korean help.
