The risks of climate change now need little introduction. We are already starting to live with the impacts of a changing climate on communities, businesses and supply chains.
The most recent Intergovernmental Panel on Climate Change (IPCC) report delivered the unnerving news that we now have less than a nine-year window to act on climate and limit global warming to 1.5ºCelsius. It made plain that limiting warming to 2°C will not be enough to prevent the most serious impacts.
To limit global warming to below 2°C and as close as possible to 1.5°C, the world must reduce net greenhouse gas (GHG) emissions to net zero by mid-century. To achieve that, we must electrify as many economic activities as possible, use hydrogen primarily made from electricity in many others, and totally decarbonise electricity supply. Other technologies such as carbon capture and storage or use (CCS/U) and sustainable bioenergy will also need to be deployed.
