What is climate scenario analysis and transition plan?

Learn about climate scenario analysis, steps to develop a climate transition action plan, climate physical and transition risks, climate adaptation and other frequently asked questions (FAQs).

Mandatory climate reporting in Australia (AASB S2) requires organisations to perform climate scenario analysis, provide information on their climate transition plan and disclose their climate-related risks and opportunities over the short, medium and long-term.

What are climate scenarios?

Climate scenarios are imagined future climate situations.  A number of standardised scenarios have been developed by scientists and have different levels of physical and transition risks (see table below).

What is climate scenario analysis?

Climate scenario analysis involves assessing how various possible climate futures could impact an organisation's business model, operations, and finances in different ways. Under IFRS S2, companies can use standardised scenario or develop their own climate scenarios. However, as per the Australian climate reporting regulation, two climate scenarios shall be considered, including a high global warming scenario (2.5°C or higher) and a low global warming scenario (1.5°C above pre-industrial levels). Scenario SSP2-4.5, SSP3-3.7 or SSP5-8.5 are examples of high emission scenario while SSP1-1.9 would correspond to a low emission scenario. Australian companies are also required to disclose information on the inputs used for the scenario and the key assumptions underlying the scenario.

The results of the scenario analysis can be disclosed using qualitative and quantitative information. For instance, a bank could disclose the percentage of its corporate loans exposed to drought or flood risks under an SSP1-1.9 scenario versus an SSP3-3.7 scenario.

What is a climate transition plan?

A climate-related transition plan describes the strategy developed by an organisation to transition to a more climate conscious business model. It includes targets such as GHG emission reduction targets, a description of actions planned to transition to a low carbon economy and become more sustainable as well details on the corresponding resources to enable that transition and meet targets.

How to develop a climate transition plan?

Developing a climate transition action plan requires in depth reflections about the strategy and business model of the organisation. While making aspirational commitments is often a starting point, it is important to back these commitments with concrete actions and dedicated investments.

What are climate risks & opportunities?

Climate-related risks and opportunities are physical and transition risks and opportunities that an organisation faces due to climate change and the transition to a lower carbon economy. In line with TCFD recommendations, the Australian Sustainability Reporting Standards (ASRS) require companies to disclose their climate-related risks and opportunities over the short, medium, and long term.

What are climate physical risks?

Physical risks are risks arising from climate change such as extreme weather events (storm, flood, drought…) that may affect the assets, operations and supply chain of a business. There are acute physical risks that are event-driven or chronic physical risks that relate to long term change in weather patterns. The resulting financial impacts could be direct (e.g., damage to assets) or indirect (e.g., supply-chain disruption).

What are climate transition risks?

Transition risks include policy, legal, technological, market and reputational risks. A change in regulation such as the introduction of a carbon tax could increase operating costs.

What are climate opportunities?

Climate-related opportunities are the opportunities that the company may seize from climate-related changes or events. This may include innovation and investment in low-emission technology to capture new markets or adjustment to current products and services to follow shift in consumer preferences.

FAQ

1. What are the benefits of conducting climate scenario analysis?

Conducting a climate scenario analysis enables organisations to understand how their current business model and supply chain will hold under different future climate situation. This gives organisations an opportunity to adjust their strategy and business model to become more climate resilient and seize future market opportunities.

2. Why should I report climate scenario analysis?

Reporting the results of the climate scenario analysis is required under IFRS S2 and AASB S2. Besides, these results provide useful insights for investors to assess the climate resilience and adaptation of a business.

3. What is climate adaptation?

Climate adaptation refers to a business's capacity to prevent financial losses caused by climate change. Actions could include adjusting the current business model, developing innovative solutions minimise potential effects of floods, drought, etc or explore market opportunities offered by the green transition.

4. What is climate mitigation?

 Climate mitigation means contributing to lowering greenhouse gas emissions in the air. For businesses, this involves taking actions to reduce their scope 1, 2, and 3 emissions.

5. What is climate resilience? 

Is characterised by the ability for a business to anticipate, plan for and respond to climate related events and changes. The way to improve your resilience is making more decisions in the present to mitigate the climate-related risks and take action to respond to these now for less detriment in the future.
