The Paris Agreement and the 2030 Agenda for Sustainable Development were both adopted in 2015. As illustrated by the Connect4Climate infographic, the implementation timing of the instruments is closely related and there are a lot of synergies between nationally determined contributions to achieve carbon neutrality in 2050 under the Paris Agreement and 17 UN Sustainable Development Goals to be reached by 2030.
Infrastructure plays a key role in supporting the achievement of the SDGs and the Paris Agreement since it delivers essential services including energy, water, communications, healthcare and education. At the same time, infrastructure is also part of the problem since it a major source of GHG emissions and will be responsible for the biggest part of adaptation cost as illustrated in the table below (source: UNOPS 2021 report “infrastructure for climate action”)
