Climate mitigation vs climate adaptation: what is the difference?

You might have heard the terms climate mitigation and climate adaptation before and wondered what they mean, and what role they play in achieving net-zero?

We speak to businesses every day that ask us these kinds of questions, so we’re here to break it down in this article. As part of this guide we’ll cover:

• What are the definitions of climate mitigation and climate adaptation?
• What are the climate strategies associated with them?
• What’s the purpose of each approach?
• What kind of costs are associated with each approach?
• What’s their role in achieving net-zero?
• What types of projects do they involve?
• How are the projects certified?

Definition of climate mitigation and climate adaptation

Climate mitigation

Involves actions taken to reduce or prevent the emission of greenhouse gases into the atmosphere, with the goal being to limit the extent of climate change.

Climate adaptation

Refers to measures taken to adapt to the impacts of climate change that are already occurring or are projected to occur. Adaptation focuses on minimising the negative effects of climate change, and building resilience to climate-related risks.

Types of climate mitigation and climate adaptation strategies

Climate mitigation

Strategies include transitioning to renewable energy sources, improving energy efficiency, implementing carbon capture and storage (CCS) technologies to capture CO2 emissions, and promoting afforestation and reforestation efforts to increase carbon sequestration.

Climate adaptation

Strategies include developing climate-resilient infrastructure, implementing water conservation practices, establishing early warning systems for extreme weather events, shifting to more resilient agricultural practices, and protecting and restoring natural ecosystems.

What is the key purpose for climate mitigation and climate adaptation

Climate mitigation

The primary objective is to reduce the amount of greenhouse gases in the atmosphere, thereby slowing the rate of climate change and its associated impacts, such as rising sea levels, extreme weather events, and disruptions to ecosystems.

Climate adaptation

The main objective is to reduce the vulnerability of human and natural systems to the impacts of climate change, enhance their capacity to cope with climate-related risks, and promote long-term resilience in the face of changing climatic conditions.

Climate mitigation and climate adaptation costs

Climate mitigation

Measures often involve up-front costs, but this can lead to long-term cost savings. Over time, the adoption of new technologies costs less and results in greater benefits, such as we have seen with renewable energy technologies.

Climate adaptation

Measures also incur costs, but these are typically focused on adapting infrastructure to withstand changing environmental conditions. Adaptation costs may vary depending on the scale of the project and the vulnerability of the affected regions.

Role in achieving net-zero

Climate mitigation

Interventions are crucial to achieving net-zero by reducing the amount of greenhouse gases in the atmosphere. Mitigation efforts aim to balance sources of emissions with sinks, ultimately leading to net-zero emissions. 

Climate adaption

Is essential for building resilience to climate impacts, but does not directly contribute to achieving net-zero emissions. Instead, adaptation measures focus on minimising the negative effects of climate change on communities and ecosystems, enhancing their ability to cope with climate-related risks.

Types of climate mitigation and climate adaptation projects

Climate mitigation

Projects reduce greenhouse gas emissions or enhance sequestration. These can include renewable energy projects, energy efficiency improvements, afforestation and reforestation initiatives, adoption of low-carbon transportation systems, and carbon capture and storage (CCS) projects. 

Climate adaptation

Projects focus on building resilience to the impacts of climate change. This may involve constructing climate-resilient infrastructure, implementing water conservation strategies, developing early warning systems for extreme weather events, restoring ecosystems, and transforming agricultural practices.

Certification

Climate mitigation

Projects often undergo certification processes to verify their carbon reduction or removal activities and ensure their compliance with established standards such as the Verified Carbon Standard (VCS), the Gold Standard, or the Clean Development Mechanism (CDM) under the Kyoto Protocol.

Climate adaptation 

Projects have no specific certification schemes, but some organisations may seek recognition for their climate resilience efforts through programs focused on sustainability or climate adaptation planning. However, certification for adaptation projects is less standardised compared to mitigation projects.

In conclusion

Climate mitigation is primarily concerned with reducing the amount of greenhouse gases in the atmosphere, and limiting further climate change. Whereas climate adaptation is mostly concerned with building resilience and adapting to the impacts of climate change. Both approaches are critical for addressing the challenges of climate change and transitioning towards a sustainable and resilient future.
