With 93% of Eskom's electricity generated from coal-fired stations, this already implies a major environmental footprint. This also means an impact on water - a critical issue for South Africa where water scarcity is an important matter. For this reason the new Medupi and Kusile power stations will use dry cooling technology. Our relative water usage is 1.35 L/kWh sent out and our plan is to reduce this by 10.4% to 1.21L/kWh by 2015/16.
The most topical of the environmental impacts is our carbon footprint. Due to the coal-centric nature of our generation mix, we are not satisfied with our current performance in this regard. Eskom's CO2 emissions for the period were 230.3Mt, an increase of 2.5% on the previous year's 224.7Mt. We remain committed to reducing our emissions as conveyed in our climate change strategy. Our commitment is to see a reduction by 2030. Subject to the support from the shareholder and the allocation of nuclear and renewables to Eskom, this reduction follows what we anticipate to be our peak at 283Mt in 2022 to 235Mt by 2030. This will see our relative CO2 emissions at 0.68t/MWh compared to the current 0.99t/MWh. No company takes pride in the negative impacts of its business, and Eskom is no different. One of Eskom's objectives is to become a greener energy company.
In this context, Eskom will contribute through a comprehensive six-step approach that includes supply measures, such as the diversification of the generation mix, as well as demand-side interventions, such as supporting energy efficiency measures to reduce demand. Some are more macro in nature, such as ensuring that we adapt to the impact of climate change by increasing the robustness of infrastructure designs, fostering innovation, investments in the emerging global CO2 market trading regime and progress through advocacy, partnerships and collaboration with environmental organisations. On all dimensions of this critical global debate, Eskom will seek to contribute and lead where necessary.
One change that we desperately need in South Africa is the more sustainable use of energy. Eskom has taken up the challenge and is leading a campaign to unlock the potential of 49 million South Africans to reduce their energy consumption and think of energy in a sustainable manner. The "49M" movement, launched and endorsed in March 2011 by Mr KP Motlanthe, the Deputy President of our Republic, together with the Ministers of Public Enterprises and Energy, is material to the continued mitigation of an extremely tight situation of supply versus demand. We also value the support from and partnerships with various key customers and organisations for this initiative. It is imperative that we pull together as a nation to harness our collective power in saving energy.
