In addition to measures such as reforestation or moorland rewetting, material innovations are an instrument against climate change. Innovative materials in products such as solar cells or batteries, for example, can help to ensure that more solar energy is converted into electricity, regenerative energies are better stored, fewer raw materials are used and overall fewer climate-damaging emissions are produced. Combined with improved recycling strategies, these measures help to slow down climate change. But this can only succeed in connection with further societal transformation processes (e.g. mobility, urban development).
