Why we monitor sources of carbon dioxide

This indicator estimates the proportion of carbon dioxide (CO2) in the air coming from industry, motor vehicles and domestic heating in the Waikato region.

Carbon dioxide is a greenhouse gas. It's thought that increasing amounts of these gases will cause world-wide climate change. Waikato Regional Council estimates the carbon dioxide being produced by motor vehicles, industry and home heating to determine where the carbon dioxide in our air is coming from. We need to know this so we can reduce existing sources of pollution and predict any future problems that may arise.

What's happening?

The main sources of air pollution in the Waikato region are motor vehicles, home heating and industry.

Environment Waikato monitors air pollution from motor vehicles, home heating and industry in:

  • Hamilton
  • Tokoroa
  • Taupo
  • Te Kuiti
  • Putaruru
  • Matamata
  • Waihi
  • Te Awamutu
  • Ngaruawahia
  • Turangi

We usually monitor air pollution in winter, as levels of air pollution are usually highest during this season. We estimate where carbon dioxide in air comes from and how much is coming from each of the three main sources. This information helps us to identify potential impacts on air quality in different parts of the region and changes in air quality over time.
