The recent advances in nanotechnology and nanoscience have introduced nanoscale materials with emergent physical and chemical properties to transform the world.

Marine protected areas offer one of the best options for maintaining or returning ocean and coastal ecosystems to healthy conditions, particularly when developed as part of a wider management system. Ecological benefits come from protecting species, habitats and ecosystem functions. Social benefits come from engaging stakeholders in the planning and the fair sharing of benefits. Economic benefits come from ensuring the long-term sustainable use of natural resources and tourism incomes. The combined impact could support many of the 17 Sustainable Development Goals of the 2030 Agenda for Sustainable Development, including reducing poverty, improving food security and tackling impacts of climate change.

The eighth UN Environment Emissions Gap Report provides an up-to-date scientific assessment of the global progress towards the emissions reductions required to be on track to meet the long-term goal of the United Nations Framework Convention on Climate Change (UNFCCC).
The overall conclusion of the assessment is that government and other stakeholder’s emissions reduction commitments are far from the level of ambition required for an emissions pathway consistent with staying below a 2°C, let alone a 1.5°C, temperature increase.
