How on earth does this reduce carbon footprint?

Yeah, but offset by the amount of carbon released during construction of the highway risked, plus not to mention it is merely redirecting cars via a different route.

I buy the shorten travel time, but that translating to overall reduction of carbon footprint is kinda bull.

Even  my investment will benefits if skip n kidex.

i stilk say no to it.

only support mass trabsportation like train which is much sustainable and improve city living standard.

Yup agreed. You can only possibly reduce carbon footprint by having efficient public transportation systems like MRT/LRT or reduce the number or cars on the road.

Building another highway won't reduce carbon footprint because you're merely giving more roads and avenues for cars to travel.

If KIDEX claims to reduce carbon footprint, it's just pure marketing bull. And those hanging gardens they're proposing isn't a solution.

To solve congestion issue by building more highways is like trying to cut vege with a samurai sword.

Even tho u can cut it , but its not the right tool. N its expensive too. So u should find a appropriate knife. N one of the right tool for the issue right now is to improve the public transport systems. Even though it will not fully resolve the congestion issue, it is at least  the right start and then we can build on from there.

Don't understand why people keep complaining building highway is expensive and it's their concern. The money to build it came from conssession Kidex company. The more costly, it's their issue. They have to manage their fund. And if they charge too high in tolls collection, no one force you die die have to use Kidex. There is still ldp for you.
All I can say is, Selangor government did not look at big picture when decide to cancel kidex. Tats the last term I'm going to vote for them. Frankly it's lousy for them to just cancel like tat.
