New tool directly links carbon emissions to amount of environmental and economic damage caused

New tool directly links carbon emissions to amount of environmental and economic damage caused

Summary

Scientists have created a new tool called the Carbon Impacts Tracer that links carbon dioxide emissions directly to real-world climate harms, like heat exposure and coral death. This tool helps show the specific damage caused by fossil fuel projects, such as the proposed HVO coal mine in New South Wales, making it easier to understand the impact of carbon emissions.

Key Facts

  • The HVO coal mine in New South Wales could emit about 809 million tonnes of carbon dioxide if approved.
  • These emissions would cause an increase of 0.00036°C in global warming.
  • The Carbon Impacts Tracer translates emissions into effects like exposing nearly half a million people to extreme heat and killing millions of coral colonies.
  • The tracer estimates impacts in areas such as food production loss, lost work hours due to heat, glacier loss, and coral death.
  • It uses a climate science measure called Transient Climate Response to CO₂ Emissions (TCRE), which links CO₂ amounts to temperature rise.
  • The tool is based on peer-reviewed scientific studies and offers a clear, evidence-based connection between emissions and climate harm.
  • It aims to help hold governments and companies accountable by showing the real impacts of their emissions.
  • The tool was developed by Australian scientists and funded by the Minderoo Foundation.
