Why we focus on business

A massive 40% of New Zealand’s energy-related emissions come from the business sector.

The largest portion of this comes from industrial process heat — the  steam, hot water or hot gases used in industrial processing, manufacturing and space heating. About half of New Zealand's process heat demand comes from burning coal or natural gas.

The good news is, there are a number of low-emissions alternatives available for businesses that not only reduce emissions, but can also lower energy costs and improve profitability.

How process heat is used in New Zealand

Use by sector

  • 79% by the industrial sector — including sawmills, pulp and paper mills, and food processing plants (including dairy).
  • 10% by the commercial sector — mainly in shops and office buildings.
  • 7% by the public sector — schools, hospitals, prisons and public administration buildings.
  • 4% by the agricultural sector — mainly for indoor cropping (glasshouses).

Types of fuels used and their impact

  • 38% natural gas — accounting for 50% of the greenhouse gas emissions from process heat.
  • 11% coal — 26% of greenhouse gas emissions (coal holds the highest carbon content of any fossil fuel, and is more emissions intensive per unit of industrial output than any other source).
  • 23% wood-derived fuels (including black liquor)— 1% greenhouse gas emissions, collectively.
