Mr Dennis Tan spoke extensively about the pollution issues. Let me try to address the five different questions as best as I can. On air pollution, I think this is why the Singapore Government has embarked on this Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) on a voluntary basis. We want to make sure that the aviation system is sustainable. So, together with the noise pollution that the Member mentioned, we have not done a study on air or noise pollution, but, from my own experience, the aircraft that come into Changi have newer technologies, newer engines. So, the pollution index is lower, the noise index is also lower. Furthermore, because of our urban planning, Changi Airport is situated to the east of Singapore, away from the populace. That is a design that has served us very well for the last 40 to 50 years – moving from Paya Lebar to Changi. So, the noise that aircraft bring in the dead of night is a lot lower and, as far as I remember, it does not impact the environment, in terms of noise, for residents in the east side.
