Comparing two environmental regulation

Preventing emissions vs improving water quality,

Which one better?

https://t.co/zLrVNWIPXm

What is the Difference?
We certainly often hear the term better to prevent than cure. Of course, we all agree on that. But what about improving quality, is that better than preventing?

A researcher named Dan Pan tries to compare 2 different regulations on environmental impacts.
One of the regulations is based on environmental quality limits. the other is based on the market, but we will call it improving water quality because it gives reward and punishment on environmental performance.
Preventing Emissions:

• Restrictions or closings of companies that violate environmental quality standards

• Restricted areas must protect their water

• Implementing comprehensive water conservation

• Strengthens water recovery and protection
Improving water quality

Give awards to mayors whose evaluation scores are good, and adequate, whose evaluations are bad. There are several parameters defined in determining water quality such as: COD intensity, water quality, and industrial wastewater standards
Result

Result
The results showed that environmental regulations based on improving quality had a better impact on reducing COD than preventing regulations.
Improving quality regulations provide better results but require a lot of funding too. Therefore, the central government must monitor periodically in order to allocate funding appropriately
Suggestions

Each region has different waste and environmental conditions. So one regulation cannot be applied to other regions.

@danielashby @AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd I'll bite. Let's try to keep it factual. There's a reasonable basis to some aspects of this question, that it might be possible to agree on. Then there are other, more variable, elements which depend on external factors such as transport and energy policy. /1

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd First up, we know reasonably well how much energy it takes to propel a high-speed train along the HS2 route. We can translate that into effective CO2 generated by making some assumptions about how green the electricity grid is. /2

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd Secondly, we have a reasonable grasp of how much CO2 is going to be generated by building HS2 - there are standard methods of working this out, based on the amount of steel, concrete, earthmoving, machine-fuelling etc required. /3

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd Thirdly, we can estimate how much CO2 is generated by cutting down trees, and how much is captured by planting new trees. We can also estimate how much CO2 is needed to keep the railway running and generated by maintaining the track /4

@AdamWJT @Greens4HS2 @TheGreenParty @GarethDennis @XRebellionUK @Hs2RebelRebel @HS2ltd We know how much CO2 is saved by moving goods by freight train on the lines freed up by moving the express trains on to HS2, rather than by truck. /5
