Strengthening forward-looking strategic scenarios in the private sector

Sectoral climate change mitigation scenarios for strategy development and alignment assessment by economic players:
Current status and future prospects for taking further account of nature and resilience

Economic players must face climate change and sustainability issues by transforming economic models, while strengthening their competitiveness and resilience:

• 2024 is the first year to exceed 1.5°C above pre-industrial levels (CCCS 2024). For the first half of 2024, the costs associated with all natural disasters worldwide amounted to around US$120 billion (more than two-thirds of which related to storms, floods and forest fires) (Munich Re 2024). Europe has not been spared, with warming twice as fast as the global average and significant costs associated with recent extreme weather events (CCCS and WMO 2024, EEA 2023).
• The major transformation of economic models relies on science-based frameworks to assess the risks and opportunities to elaborate policies that increase innovation and strengthen the competitiveness and resilience of business. Collective efforts have so far mainly focused on climate change mitigation. The Paris Agreement sets objectives to limit the increase in global average temperatures, cap greenhouse gas (GHG) emissions and achieve net-zero emissions in the second half of the century. Sectoral climate change mitigation scenarios consistent with the Paris Agreement are central to this, as they incentivise major transformations at the financial asset, firm and sector levels; economic players use these scenarios to set interim targets and measures that convert temperature goals and GHG emission reductions into policy milestones and design strategic plans accordingly.

This paper gives decision-makers an overview of the current thinking on these scenarios that drive sectoral and business transformation, avenues for improvement, and targeted actions towards a sustainable economy. It recommends that economic players and scenario designers explore the wider opportunities that arise from having greater consistency between their approaches to climate and nature to define consistent strategies and increase co-benefits:

1. To reach a sustainable economy, greater interoperability of overarching science-based frameworks (Paris Agreement, Global Biodiversity Framework alongside the Sustainable Development Goals) through policy and implementation interlinkages between nature and climate is critical; the objective is to better align around consistent objectives and reinforce each other.
2. Further criteria and assumptions should be considered to assess the consistency of climate change mitigation scenarios with the Paris Agreement, in view of earth resilience.
3.  Fully assessing the consistency of sectoral climate change mitigation scenarios with the Paris Agreement requires an understanding of the way in which nature is considered.
4. Faced with complex and uncertain futures, climate change mitigation scenarios should be supplemented with a broader number of strategic options, to strengthen competitiveness and resilience within the planetary boundaries.
5. Scenario designers should also extend the sectoral and geographical coverage and granularity of scenarios towards greater sector resilience.
6. Economic player efforts should focus on strengthening their forward-looking strategic analyses, including new circular business models for greater competitiveness, strategic autonomy and resilience.
7. Scenario designers should further enhance the transparency and comparability of scenarios.
