The Botanic Gardens Climate Change Alliance's objectives include: developing strategies to mitigate the threats of climate change and managing living plant collections through the exchange of knowledge and methodologies among relevant organisations involved in plant biodiversity conservation; using global collaboration to address the threats of climate change facing plant species; sharing and developing knowledge, strategies, and methodologies to address climate change and the management of living collections; and creating a roadmap for continued engagement within networks of botanical organisations.

Climate change is a global challenge that knows no borders and, in order to combat it, requires the coordinated work of all agents involved in the defence of global biodiversity. Botanical gardens are places of scientific and technical knowledge that play an essential role in the conservation of our natural environment. As institutions that connect research, conservation, education and outreach, they are ideal centres for promoting the fight against climate change, bringing together all the parties involved. With this objective in mind, the botanical gardens that make up the Ibero-Macaronesian Association (AIMJB) met at the La Concepción Historical-Botanical Garden in Malaga and agreed to join the Alliance against Climate Change created in 2018 in Melbourne (Australia) through the so-called Malaga Declaration.
