Location of the Hannover region

Hannover region – in the heart of Europe•21 town and rural district authorities•Around 1.2 million inhabitants•Covering an area of 2,300 square kilometres


Transition to renewable energies in Germany (agreed 2011)

Year Reduction in greenhouse gases Power generation from renewable energy

2020 - 40% 35%

2030 - 55% 50%

2040 - 70% 65%

2050 - 80 to -95% 80%

In 2011, Germany’s Federal Ministry of the Environment launched its action programme to implement the energy transition at regional level: Masterplan: Giving 100% to combat climate change

Targets on climate change by 2050

Greenhouse gas emissions 95% reduction compared with 1990 level Energy consumption 50% reduction compared with 1990 level

These goals have already become policy (June 2012)

Hannover City Council: unanimous

Regional assembly (Regionsversammlung): by a large majority

With the ‘Masterplan: Giving 100% to combat climate change’, both City and Region are pressing ahead with the goal of taking appropriate long-term ecological and economic action to reduce greenhouse gases by 95%.

They will do this by:exploiting potential for enhancing energy efficiency, saving energy and developing a sustainable lifestyle;

using renewable energy, especially from regional sources; and

closing material cycles.

Environment Ministry’s action programme: targets

Project run by: Hannover City and Region Hannover authority

Duration: four years, June 2012 to May 2016

Phase 1: ends March 2014

Total value: €1.2m (€600k for each; proportion funded: 80%)

Patron: Professor Gesine Schwan

The energy transition will only succeed with a concerted effort at all levels of government, the business community and society.

(Berlin Ethics Committee, May 2011)

Drawing up the Masterplan involves a broad-based participatory process

to which over 200 experts from industry, science, NGOs and government contribute.

Art and culture (symposium)


1. Scenarios: potential for savings and renewability

2. Energy supply (incl. grid- and storage-related aspects)

3. Building energy efficiency (focusing on housing stock)

4. Transport/travel and space

5. Regional economic cycles / waste management

6. Business community

7. Climate-friendly everyday routines (lifestyle change)

Experts from industry, science, NGOs and government Task: preparing a strategy paper for each aspect with assistance from the City, the

Region Hannover authority and the external Bureau

Core element: seven strategy groups

Work by the strategy groups

A total of 240 institutions and businesses involved so far

Each strategy group meets five to seven times a year

Example for Vision 2050 (I): Strategy Group on Energy Supply

Energy generation from wind, solar power and sustainable bioenergy – ‘visible’ at local level on a daily basis, and without nuclear-generated power

Heating and cooling for buildings: only a minimum needed, generated with optimum use of primary-energy sources

Energy system: strongly fluctuating energy production must be compensated for (grids, storage, power stations as backup)

Control/Organisation: market design determined by energy system, intelligent management, electricity will become central form of energy

Extensive storage systemestablished to safeguard supply

Example for Vision 2050 (I): Strategy group on lifestyle changeIn general, people enjoy living in the Hannover region and have a good quality of life here; diversity in culture, faith communities and art is an important source of ways to develop one’s life.Consumption and industry are guided by the common good

Education is self-directed, voluntary, creative and relevant to life

Energy supply is ‘visible’ at local level on a daily basis, nuclear-free and affordable

Housing: community space; flexible; green recreational areas; multi-generational; area covered by roads has fallen, creating more green space

Food is regional; organic; canteens are meat-free

Leisure opportunities are close at hand, not far away

Getting around is easy, with short journeys to school, work, the shops, and public-transport stops and stations
