Where is Edinburgh?
Edinburgh has been the Scottish capital since the 15th century. Inscribed on the World Heritage List in 1995, the Old and New Towns extend over 1.78 square miles and contain approximately 4,600 buildings of different types, built across a dramatic topographic setting.

Why is this such an issue?
Old roof and rainwater management systems as well as drainage will become insufficient as existing systems will be unable to cope with the level of storm water associated with extreme and more frequent weather events. Additionally, if temperatures continue to rise, the rate of decay will increase further due to processes like the freeze-thaw cycle, the mobilisation of salts, and deposition of material.

How is this affecting Edinburgh's buildings?
The age of many of the buildings within the World Heritage site presents challenges in withstanding the effects of climate change. Most buildings are made from porous sandstones and increased wetting and drying increases the decay of these stones.

What is Edinburgh doing to combat climate change?
Scotland has one of the most ambitious climate change mitigation goals globally and has set a goal of a 42% reduction in greenhouse gas emissions by 2020 and an 80% reduction by 2050. In 2019 a 47% reduction was reached, and new targets were set for 75% by 2030, 90% by 2040; and net zero by 2045.
How is Edinburgh integrating these goals into communities?
In 2016, twenty civic organisations, including The City of Edinburgh Council and Edinburgh World Heritage, developed the Edinburgh Adapts action plan which specifies concrete goals for dealing with climate change and making the city more resilient.

How is Edinburgh strengthening its historic environment?
As part of Scotland’s push for building resilience, Historic Environment Scotland set out to identify environmental hazards to their sites and found that many sites are exposed to risks like flooding, coastal erosion and slope instability that will be exacerbated by climate change.

Through this work they have been able to develop new maintenance guides for Edinburgh historic building owners focused on what they can do to ensure they are adapting to climate change.

What more needs to be done?
Combating climate change requires innovative action. 3D capture technology provides a tool for further understanding, evaluating, and producing conservation management plans. It can also be used to connect broader audiences with unique cultural heritage, demonstrating global diversity and shared understandings.
