ECO12: Non-carbon energy share in energy and electricity 
Brief Definition 
The share of non-carbon energy sources in primary 
energy supply (TPES) and in electricity generation 
and generating capacity 
Units 
Percentage 
Alternative Definitions 
None 
Agenda 21 
Chapter 4: Changing consumption and production 
patterns 
POLICY RELEVANCE
(a) Purpose: This indicator measures the share of non-carbon energy sources in 
TPES and electricity generation and generating capacity. 
(b) Relevance to Sustainable Development: The promotion of energy and of 
electricity from non-carbon sources is a high priority for sustainable development for 
several reasons, ranging from environmental protection to the energy security and 
diversification of energy supply. An increase in the share of non-carbon fuels reduces 
the specific emissions — that is, emissions per unit of total energy and electricity used 
— of greenhouse gases (GHGs) and other pollutants affecting local air quality and 
regional acidification. The introduction of carbon taxes targets, to a large extent, a 
shift towards a higher share of non-carbon energy sources in the primary energy mix. 
(c) International Conventions and Agreements: None. 
(d) International Targets/Recommended Standards: At the World Summit on 
Sustainable Development in Johannesburg in 2002, an agreement was reached to 
increase the global share of renewable energy sources. In some countries, there is a 
target for a certain percentage of energy supply from renewable sources. For example, 
in the European Union a directive sets quantitative targets for electricity from 
renewable energy to be 21% by the year 2010, as well as indicative targets for each 
Member State.
(e) Linkages to Other Indicators: This indicator is linked to fuel shares (energy 
mix) and shares of renewables in energy and electricity. The indicator is also linked to 
indicators of energy use and electricity generation and to environmental indicators 
such as GHGs, etc.
