Energy as a Key Element of an Integrated Climate Protection Concept for the City Region of Gauteng


The EnerKey project is a South African – German collaboration, which aims to develop and implement innovative pathways and projects in urban energy supply and use in order to improve the sustainability in the region of Gauteng, South Africa. Gauteng is an urban agglomeration, where the three municipalities Johannesburg, Ekurhuleni and Tshwane with more than 10 mn inhabitants are located. EnerKey stands for the focus of the project on “Energy as a key element of sustainable transformation”.

Phase one of the project began in 2005. More information to the phase 1 (the pre-phase) can be found on the previous website. The main phase of the project began in June 2008.


Further information on EnerKey is also provided as pdf documents in the download section.

Rev.: October 2012)


The greenhouse gas (GHG) inventory for Gauteng province was developed in order to establish a baseline for Gauteng’s energy consumption, energy balances were developed that are the foundation to also calculate GHG emissions. 
One of the strength of this GHG inventory is that it takes into account that there are only little electricity generation and no refinery capacities within Gauteng’s boarders by differentiating between territorial (e.g. GHGs emitted in Gauteng) and accountable non-territorial (e.g. GHGs emitted outside Gauteng’s boarders in the energy conversion sector for energy that is consumed by end-users in Gauteng) GHG emissions. In addition, accountable non-territorial GHG emissions are allocated to end-use sectors. This enables the compilation of an allocated end-user inventory which illustrates GHG emissions related to final energy consumption by sector (click to download). 



EnerKey Technology Handbook - A guide of technologies to mitigate greenhouse gases towards 2040 in South Africa (Rev.: September 2012)


The EnerKey Technology Handbook summarizes different technologies to mitigate greenhouse gases to raise the awareness of local stakeholders for energy efficient technologies. It provides basic information about the potentials of each technology and the current political framework regarding each technology. The handbook covers conventional technologies as well as possible (future) alternatives for the different demand and supply sectors. These sectors, namely transport, residential and electricity generation, outline the structure of the handbook. An economic, technical and environmental outlook for the year 2040 completes every handbook sheet (click to download).



The EnerKey Schools Project - Materials on Energy and Climate Education: An Overview (February 2012)


Worldwide energy and climate education in schools is being recognized more and more as an important issue. Today we face a situation when the negative effects of climate change are becoming more and more apparent. The upcoming generations are going to be hit by these effects the most severely. This is the basis why it is important to introduce energy and climate education in schools today in order to educate a responsible and conscious generation, which will be aware of the risks and threats associated with climate change and ways to cope with them. This challenge is taken up by the EnerKey Schools Projects which aims to sensitize teachers and learners in Gauteng Province for clean energy solutions. One crucial deliverable to empower teachers as well as learners is the overview on energy and climate education materials (click to download).

COP17 EnerKey for COP 17

The 17th Conference of the Parties (COP 17) to the United Nations Framework Convention on Climate Change (UNFCCC) have now come to an end. Since the UNFCCC entered into force in 1995, the Conference of the Parties (COP) to the UNFCCC have been meeting annually to assess progress in dealing with climate change. Further information on EnerKey's contribution to COP 17 you can find here.
