Rationale With the presentation of the first Hamburg Climate Plan, the Senate has further developed the Climate Action Master Plan (official report 20/8493 of 25 June 2013) and the Adaptation to Climate Change Action Plan (official report 20/8492 of 25 June 2013), in terms of both methods and content, bringing together climate change mitigation and adaptation to climate change. In addition, in the Hamburg Climate Plan the Senate reports to Parliament on the achievement of the targets set by the Climate Action Master Plan and the Adaptation To Climate Change Action Plan, the achievement of the objectives in individual areas of action and projects, and new developments. B. Summary Hamburg is conscious of its global responsibility and has been promoting climate mitigation for many years. At the same time, the measures required to adapt Hamburg to climate change are being put in place. Hamburg has already pointed the way with its Climate Action Plans. Many cities – at home and abroad – have copied Hamburg. But so far only a few countries and cities have looked at both components – climate mitigation and climate adaptation – in an integrated way. Both aspects have already been reflected in the Hamburg Climate Action Plans, and the integration of adaptation into climate mitigation is also an important component of the overall concept in the Climate Action Master Plan agreed in 2013. The Adaptation to Climate Change action plan has been drawn up in parallel to this. This first Hamburg Climate Plan provides Hamburg with a vision of a modern city of the future in which climate mitigation and climate adaptation are fundamental components of our shared society. Hamburg will become a "Climate Smart City". What is needed are clear forward-looking aims that contribute to a positive image of Hamburg as a smart, climate-friendly city adapted to climate change and that are rooted in the city's society. These aims and measures are described in this first Hamburg Climate Plan. This provides an integrated study of climate mitigation and adaptation which significantly expands the thematic scope of the climate strategy. Climate change already affects the quality of life in the city. In the future it will increasingly impact all areas of urban life. Extremes are to be expected in different directions: increased drought but also more heavy rainfall events. The Hamburg strategy therefore aims at making the city more resistant and robust in the face of climate events i.e. at increasing the city's resilience. The Climate Plan commits to setting the course for adaptation to climate change in good time and, in particular, takes on the challenge of implementing water management concepts aimed at minimising damage from flooding and heavy rainfall events to persons, property and the environment in the coming decades. 4 By 2050 Hamburg wants to gradually reduce CO2 emissions by at least 80 per cent in comparison to 1990. The target is to halve CO2 emissions in Hamburg by 2030. The city will therefore enhance the measures in its own jurisdiction and fully support the implementation of national policy action. In addition, around 2 million tonnes of CO2 emissions are to be cut by 2020 compared to 2012. Climate mitigation requires an energy transition and a resource transition. The consumption of energy and resources in the cities must be reduced dramatically. We must push the expansion of renewable energies and the improvement of energy efficiency in buildings and in industrial production forward, in line with technological progress. However, concentrating on this alone will not achieve the climate mitigation and CO2 reduction targets. A resource transition is needed in parallel to the energy transition. This means a more sparing use of energy just as much as a change in material flow management for a more efficient use of resources. Using resources carefully must become a key point in the Hamburg climate policy. Hamburg therefore plans to take appropriate measures in the areas of energy savings, mobility and consumption as well as buildings. As part of its long-term perspective 2050, Hamburg
