Rationale As planned, with the first revision of the Hamburg Climate Plan, the Senate is further developing the content and methods of the Hamburg Climate Plan from December 20151 and is setting new climate targets for Hamburg in the light of current developments. With this revision of the Hamburg Climate Plan, the Senate also informs the Hamburg Parliament on the development of the framework conditions for Hamburg and the targets in the Hamburg Climate Plan that have already been achieved. B. Introduction Climate change mitigation through a rapid and wide-ranging reduction of climate- damaging emissions caused by human beings is one of today's most important tasks globally. Every effort must therefore be made to reduce greenhouse gas emissions and to protect people from the consequences of major changes in the climate. With its climate plan, Hamburg is planning to initiate the necessary measures over the coming years so that citizens can continue to live in a city that is worth living in, economically successful and affordable, a large metropolis that makes its contribution to managing climate change. The climate plan is also aimed at pressing ahead with the necessary adaptation process in order to prepare the city for the impacts of climate change. The Hamburg Senate is pursuing a climate policy not just as an aim in itself. Both the rapid and wide-ranging reduction in greenhouse gas emissions and adapting the city to the climate changes which can already be detected, is a key task in the interests of Hamburg's citizens including future generations. The measures in the climate plan will enable us to make sure that the quality of life, human health and safety in our city, economic prosperity and political stability are also guaranteed in the future. This makes climate change mitigation and climate adaptation priority challenges for Hamburg and the Hamburg Senate. It is clear that the transformation process to overcome an economic and social model based on fossil resources will cause considerable changes as well as burdens and costs. We will ensure that this process is implemented in a socially fair manner. For all the measures there is a need to ensure that no one comes under too much strain, and objectives such as affordable housing are not put at risk. Hamburg, like all local authorities and states, will not be able to bear the envisaged financial challenges but will be reliant on support from the Federal Government. It must be remembered that, both on an international scale and from an individual viewpoint, the higher the income and wealth, the greater the average greenhouse gas emissions. 1 Climate Plan 08.12.2015 (Parliamentary document 21/2521) 2 For reasons of equitable distribution and the required acceptance, it is therefore very important that the costs associated with the necessary climate measures must be distributed in accordance with economic capacity. On the other hand, it is equally clear that the climate policy transformation process offers quite significant innovation and value creation prospects. As an innovative business and science location, Hamburg has an opportunity here – including on the international stage – because industrially manufactured products such as steel, copper and aluminium are already produced here with a much better CO2 footprint than in other parts of the world. In a city like Hamburg in particular, neglecting climate protection can cause huge additional problems in the future, whereas a committed and ambitious approach will result in increased competitiveness and economic strength, including with a view to future markets. Climate change mitigation and climate adaptation are challenges with a global dimension. Although resolute action locally can only make a relatively small contribution on a global scale, at the same time the per capita emissions in the metropolitan regions, especially in the industrialised countries, lie considerably above the global average. Metropolitan areas like Hamburg therefore have a particular responsibility. Over the past few years Hamburg has therefore signed a number of international agreements such as the Chicago Climate Charter and the platform of the Carbon Neutral Cities Alliance. Under these agreements the signatory cities commit to the relevant national climate change objectives, the goals of the Paris Climate Agreement and a proactive role within their own scope for action. A successful transformation process in metropolitan regions like Hamburg will work as a positive model in order to prove the technical, economic and social feasibility of decarbonisation, and to illustrate that the benefit of resolute action significantly outweigh the costs. In view of this, the Senate is undertaking active climate change mitigation and adopting the necessary measures in order to reduce the greenhouse gas emissions produced in Hamburg, quickly and comprehensively. At the same time, Hamburg will be developed into a climate-adapted and climate-friendly city, protected from the impacts of climate change but at the same time retaining its quality of life. Both in Hamburg and throughout Germany, joint efforts are required in order to reach ambitious climate goals. The challenge is on a scale that requires the cooperation of all stakeholders. We therefore need a broad social consensus for climate change mitigation which runs through all levels of our state and all sectors of the economy. Because it is only with such wide social agreement that we can succeed in taking all players on the journey to climate protection and climate adaptation and in alleviating social hardship. 3 In 2007 Hamburg resolved its first Climate Action Plan and introduced a range of measures for climate change mitigation based on this. Following this, the Senate adopted the Climate Master Plan in 2013. In December 2015 the Senate adopted the Hamburg Climate Plan which combined the findings and challenges of climate change mitigation and those of adaptation to the effects of climate change. This first revision of the Hamburg Climate Plan further develops the goals and the portfolio of measures. It also presents the status of activities in Hamburg and the changes to the framework conditions. The revision to the Climate Plan is divided into two parts. The chapter, “Climate report for Hamburg”, presents the current development in Hamburg's CO2 emissions based on the 2017 consumption account by the Statistikamt Nord (northern statistics office).
