CROSS scenarios (V2022-09)

2050 net-zero GHG target

Climate target
Target excluding emissions from aviation with two variants for emission compensation abroad

Two variants

Market integration
Low and high energy market integration

Phase-out

Nuclear policy
Nuclear phase-out at the end of existing plant lifetimes

A harmonised set of Swiss energy-system futures defined along two policy dimensions: climate policy ambition and international energy market integration

Scenario definition

Scenario space (2x2)

The four scenarios results from combining two dimension: climate policy (domestic vs. carbon removal abroad) and market integration (high vs. low)

Domestic-together

  • Climate policy: Net-zero GHG - domestic
  • Market integration: High

Abroad-together

  • Climate policy: Net-zero GHG - abroad
  • Market integration: High

Domestic-alone

Climate policy: Net-zero GHG - domestic Market integration: Low

Abroad-alone

  • Climate policy: Net-zero GHG - abroad
  • Market integration: Low

Scenario dimensions

Climate policy dimension

Two variants describe how Switzerland reaches net-zero greenhouse gas emissions by 2050:
  • Net-zero GHG - domestic: Target by 2050 achieved with domestic measures only
  • Net-zero GHG - abroad: Target by 2050 can also be achieved using carbon removal abroad

Energy market integration dimension

Two variants describe Switzerland's integration into international energy markets:
  • High integration: agreements secure market access including electricity, hydrogen, biofuels and other synthetic fuels.
  • Low integration: reduced import availability of electricity, hydrogen and other sustainable synthetic fuels.
