The growing focus on reaching net-zero emissions is definitely optimistic, and the changes required to reach net-zero emissions globally by 2050 are not well understood.

It is estimated that annual clean energy investment worldwide will need to more than triple by 2030 to around $4 trillion. This will also create millions of new jobs, significantly lift global economic growth, and achieve universal access to electricity and clean cooking worldwide by the end of the decade.

The recent (May 2021) IEA report, “Net Zero by 2050: a Roadmap for the Global Energy Sector,” briefly outlines an approach, including major factors and goals, for achieving a clean and resilient energy system.

Getting it done depends on these milestone factors by 2030:

  • No new sales of fossil fuel boilers
  • All new buildings are zero-carbon ready
  • Universal energy access

To achieve these goals by 2050:

  • More than 85% of all buildings are zero-carbon ready
  • Almost 70% of electricity generation globally from solar PV and wind
