Challenges for the Climathon 2018
The 196 climate challenges prepared by cities across the world focused mainly on mobility and waste management. Most challenges about mobility aim to solve the problem of private vehicles, improve public transport and reduce traffic in cities. Similarly, challenges about waste management focus on reducing plastics, solid waste and eliminating landfills.
Most of the challenges about energy focus on renewable energies, improve building efficiency, create new heating systems and decentralize energy systems. In the case of nature-based solutions cities focus on improving and developing green spaces and reduce heat island effects. Challenges on circular economy focus on food waste and the reduction of plastic and the elimination of landfills as well.
The main levers of change are related to citizens participation (incl. young people and inclusion), technology, behaviour (incl. culture and mindset), data and awareness. Most cities consider that the combination of many of these levers is the key of success to drive change.
- Most cities consider that city air pollution is caused by their dysfunctional and unsustainable transportation modes. Air quality depends on sustainable mobility.
- Most of the cities with rivers and channels are exploring options to improve water mobility. Additionally, cities with ports are facing similar challenges.
- Most of the cities require to build capacities (raising awareness) and preparing projects, plans, strategies. Only few are asking for implementing actions.
- Cities in the Global South and some European countries in the south of Europe are feeling the impacts of climate change more strongly and they are worried about having to deal with the emergencies. The priorities are different in each continent. However, in general the productivity of agricultural fields is being globally affected.
