Clearing the air

Zeroing in on trends in sustainable investing.

Carbon dioxide (CO2) emissions account for 70% of greenhouse gases (GHGs) in the atmosphere. Since these have a profound effect on global warming, governments, companies and investors are looking to net-zero policies to speed up decarbonisation.

Most CO2 emissions come from burning fossil fuels, but technological innovation and energy efficiency can reduce major sources of emissions from four sectors: power generation, transport, buildings and industrials. These 'decarbonisation pathways' have the potential to reduce total emissions by 81% by 2050.

Power generation

  • The highest-emitting industry¹, responsible for approximately 26% of total GHGs
  • Solar, wind, and energy-storage solutions can propel decarbonisation
  • Emerging alternatives include green hydrogen and carbon capture
     

A high proportion of carbon is currently created by power generation, so using decarbonisation technology in this sector can lead to significant change.

Transport

  • 77% of fuel is made up of carbon-rich oil and its derivatives
  • Electric vehicles are driving the industry's overall energy transition
  • Increased global regulations can reduce shipping and aviation emissions

With more alternatives to petrol being developed, and increasingly stringent regulations, the transportation sector is quickly evolving.

Buildings

  • Account for 30% of global primary energy consumption
  • Increasingly energy-efficient construction can lower this figure
  • Existing buildings can be retrofitted with green technology


Fossil fuels heat and cool structures around the world. However, new technologies like hydrogen gas, as well as new building codes, will make a big difference.

Industrials

  • Create 21% of global emissions, including significant methane²
  • Energy efficiency is a large focus in powering decarbonisation
  • Clean hydrogen may emerge as a key renewable solution


Mining, metal processing, and the production 
of gas and oil can be carbon intensive. Electrifying these industries could make them much cleaner.

Can decarbonisation affect your investment strategy?

Energy efficiency and renewable alternatives play critical roles in the drive towards net zero. Investments in specific technologies can speed up this effort. Watch emerging developments aimed at lowering emissions, as they will be key to limiting global warming.
