CLIMATE CONFERENCE EXCEEDS EXPECTATIONS
More than 700 delegates from government, business, labour, academia and civil society got together to discuss South Africa’s climate change policy this week in Midrand, north of Johannesburg. Designed to “translate political will and the best available scientific evidence into policy and action”, the summit was the start of a participatory process that will culminate in a policy White Paper on climate change by 2010 and a legislative, regulatory and fiscal package by 2012.
But first a draft document that will set out “slightly more than the skeleton” of a climate change policy will be produced by August This will be consulted widely and inform what South Africa takes into the international climate negotiations in Copenhagen in December.
Renewable energy and energy efficiency comprised a strong theme coming out of the conference. The minister of environmental affairs and tourism, Marthinus van Schalkwyk, said in a statement that “early gains can be achieved by massively up-scaling our efforts in respect of energy efficiency and renewable energy”.
But the country’s energy mix was a hotly contested issue. Coal accounts for more than 90 percent of electricity at present – but Cabinet will have the final say on whether coal’s role in the energy mix will decrease. And more technical work and a policy process that allows all views to be expressed is needed before a Cabinet decision can be made, Joanne Yawitch, a deputy director-general in the department of environmental affairs and tourism, told the media.
South African President Kgalema Motlanthe said that acting now on climate change is an opportunity to overcome the global economic crisis by creating pro-poor jobs and sustainable green growth.
The impacts of climate change are already being felt in South Africa, the conference heard, so there needs to be a balance between adaptation and mitigation. Adaptation needs more attention and funding.
The minister of environmental affairs and tourism, Marthinus van Schalkwyk, said that the summit far exceeded expectations. “I am encouraged by the strong resolve to meet the dual challenges of adaptation and mitigation by placing sustainable development and poverty eradication at the forefront. The strong consensus on making the transition to a climate resilient and low carbon economy and society will underpin our future work.”
CHINA BUILDS SOLAR THERMAL PLANT
A report from this week’s climate change conference said that Eskom may decide to build a solar thermal baseload plant later this year. Another developing country, China is about to start building its first solar thermal power station in Beijing this month, China Daily reports. The 1.5MW experimental station is expected to generate about 2.7-million kWh of electricity a year, enough to power at least 30,000 homes. The solar tower-type station, which will comprise 100 mirrors or heliostats which will redirect the suns rays to a receiver at the top of a 100m-high tower, will cost about 100-million yuan (R150-million). China plans to generate at least 150MW of power from solar thermal power stations by 2015, the report says. Full report
A THIRD WIND FARM FOR SA?
South Africa could get it’s third wind farm soon. According to a report in Engineering News, a 50MW wind farm has been proposed for the Western Cape town of St Helena Bay and the environmental impact assessment, which has reportedly been delayed for a year because of investor concerns, may start this month. David Chown of Genesis Eco-Energy, a Cape Town-based company said that once the National Energy Regulator (Nersa) announces its renewable energy feed-in tariffs, which it is expected to do at the end of this month, the company will be able to raise funding for the R850-million project. The 5.2MW Darling wind farm was officially launched last year and Eskom is building a 100MW wind farm in Koekenaap. All are in the Western Cape province. Full report
YES, YOU CAN YOU DRINK THE WATER
A new programme has been launched by the department of water affairs and forestry that will award municipalities with “Blue Drop Status” for having drinking water of excellent quality. If a town has Blue Drop status consumers will be secure in the knowledge that wastewater is managed and discharged in a sustainable, environmentally-acceptable manner, Bua News reports. Minister Lindiwe Hendricks said at the launch of the programme this week that towns would be able to use the prestigious Blue Drop Status to market themselves to both residents and tourists. She said assessments had been completed in various towns and their status would be made known soon.
CALL TO STOP NUCLEAR SHIPS ENTERING SA WATERS
Greenpeace Africa has called on the South African government not to allow two ships carrying plutonium mixed-oxide (MOX) fuel to enter its waters as they make their way from France to Japan. The shipment of about 1.8 tonnes of MOX fuel – enough to make 225 nuclear weapons – will round the Cape of Good Hope this month on two heavily armed ships protected by specially trained British forces, the environmental group says. “MOX shipments are simply not worth the risk, they are a major terror target and pose an enormous threat to the environment of all countries en route,” says Dr Rianne Teule, nuclear campaigner for Greenpeace International.

Climate change and economic recovery – an interview with Nicholas Stern
March 8, 2009
Posted in Business
We are living in the year of crisis – the biggest financial crisis since the 1930s and a climate change crisis that potentially has even greater, more dangerous consequences. But it also a time of great opportunity if we act to solve the two crises together, says economist Nicholas Stern (he of the Stern Review) in an interview for the McKinsey Quarterly.
He says we need to overcome the idea that the economic crisis takes precedence over the climate crisis because there are great returns to be had from handling the two together. We can actually be excited about the future, he says, because we have “the biggest technological opportunity that we’ve had for a very long time: as big as the railways, as big as electricity, as big as the motorcar, and, most recently, information technology. It’s the opportunity to go for low-carbon growth.”
The real challenge is to move that change fast enough, he says.

Eskom decision on solar power plant imminent
March 6, 2009
Posted in Renewable energy
Eskom is looking to the World Bank to help fund a proposed R6-billion, 100MW solar thermal power plant, Reuters reports. The power utility could make the decision to build the plant, which will provide baseload electricity, later this year. Eskom’s climate change and sustainability manager Mandy Rambharos said the plant could be built within 18 months and would be piloted for two years after that.
In 2002, Eskom completed a pre-feasiblity study for a large-scale, grid-connected concentrated solar power generation project. The study found that Upington offers one of the world’s best solar resources and that a concentrated solar power (CSP) plant built in South Africa could produce the lowest-cost solar electricity in the world to date. It also found that CSP plants could be designed to meet evening peak loads in South Africa.

The department of minerals and energy is developing a climate change strategy for the energy sector, which should be completed by the end of September, Bulyelwa Sonjica, the minister of minerals and energy said this week at the Climate Change Summit 2009 in Midrand.
The strategy will assess climate change mitigation measures for the energy sector and consider technological opportunities in energy efficiency, renewable energy and carbon capture and storage.
Minister Sonjica said that energy and climate change are “clearly intimately connected” and that mitigation offered opportunities for small and medium-sized businesses in the renewable energy and energy efficiency sectors and that climate change policies must assist in promoting these opportunities.
The renewable energy feed-in tarrif (Refit), which is reportedly due to be released at the end of this month (March), will be an important stimulus for the renewable energy industry in South Africa.
She said the department is continuing with pilot projects around wind and solar which it hopes to “upscale at the right time”, adding that “clearly more needs to be done to support both public and private investment in renewable energy technologies.”
She said that these technologies offer a number of economic opportunities and job creation benefits that our society can capitalise on.
Additional funding could come from a 2c/kWh levy on electricity from non-renewable sources that is due to be implemented this year. Deputy director-general of minerals and energy Nelisiwe Magubane was reported by Reuters as saying: “We now charge a carbon tax on electricity … we will use that to go back to the Treasury to either introduce tax breaks for people who want to invest in renewables or increase our subsidies, now at only R20-million.”
At a side event earlier in the day the minister urged South African companies to make use of the Kyoto Protocol’s Clean Development Mechanism. She said the CDM was an international tool to unlock carbon assets and very few South African companies are tapping into it.
South Africa is lagging behind other developing countries, such as India, China and Brazil with only 14 CDM projects. But it does have more than any ther country in Africa and there are reportedly another 12 local projects at the validation stage.
Some CDM projects are “low-hanging fruit that could easily be harvested”, said Ms Sonjica, adding that her department has put initiatives in place to help companies access CDM funding.
How we’re turning the ocean into plastic soup
March 5, 2009
Posted in Green News
In the late 1990s Charles Moore discovered a huge swath of plastic rubbish, “the size of two Texases”, in the Pacific Ocean. Discarded plastic accumulates there in an enormous slow whirlpool created by competing air currents known as the Pacific Gyre. Moore now carries out research on the plastic floating in the Pacific and tries to raise awareness about the problem through the Algalita Marine Research Foundation in California. The link above is a talk he gave in February on plastic pollution and it’s well worth watching.
Plastic is a petrochemical product and it never biodegrades, it photodegrades which means it is broken down into ever smaller pieces by sunlight over a very long period of time. Much of the plastic floating in the Pacific Gyre is in the form of small particles, so rather than a rubbish dump of floating bottles and bags, Moore describes it as a “plastic soup”.
A brochure on the foundation’s website says the following:
- A disposable nappy can take 500 years to photodegrade
- A plastic six-pack ring can take 400 years
- A plastic bottle can take 450 years
The first synthetic plastic, Bakelite, was produced in 1907. So, in effect, 100 years’ worth of plastic has accumulated on Earth and it’s going to keep piling up unless we do something about it.
The Pacific ocean rubbish dump has a terrible effect on marine life. Many marine animals mistake floating plastics for food. Baby albatrosses have been found with bottle tops and other plastic rubbish in their stomachs, fed to them by their parents. Plastics eaten by turtles have blocked their intestines, making the animals float so they can’t dive for food, says the website. Animals also become entangled in fishing nets and line.
All that plastic in the ocean can also affect human health. According to the research foundation the plastic in the ocean absorbs pollutants such as PCBs and pesticides. Marine organisms eat the tiny bits of plastic and these pollutants accumulate in their tissues. In this way the pollutants enter the food chain and into the food we eat. And as a result, no fishmonger can guarantee you an organic wild fish, Moore says in the TED talk.
About 80 percent of the rubbish in the ocean originates on land, washing down storm water drains and rivers into the sea. So the moral of the story is: Use less plastic
There’s an interesting article here about a research trip with Moore’s foundation to the Pacific Gyre. It’s worth a look just to see Flyp Media’s stunning online magazine. The Algalita Research Foundation’s website is also a good place to learn more.
Is clean coal really an option?
March 5, 2009
Posted in Green News
Clean coal is a term that’s bandied about in South Africa as much as it is in the United States. But it’s hard to determine whether it’s real or just wishful thinking.
If you watch the clip from CNN above, it seems clean coal means different things to different people. Bruce Nilles of the Sierra Club, says that the coal industry uses the term clean coal to mean “anything that is built post-1970 regardless of the fact that it’s spewing out large amounts of carbon dioxide”.
Technology is the key to clean coal, it would appear. But does the technology that will prevent the world’s coal power plants from belching out greenhouses gases exist yet – and on a big enough scale? The CNN clip says that not one power station in the US is fitted with carbon capture technology yet. So how far away are we from actually seeing it being installed on the coal-to-liquid fuel plants and power stations here in South Africa? Then there’s also the matter of finding somewhere to store the carbon dioxide in perpetuity.
As a developing country, South Africa doesn’t have caps on its greenhouse gas emissions like the developed countries do under the Kyoto Protocol. Huge new coal power plants are being built here and some old ones are being brought out of mothballs and recommissioned to meet the growing demand for electricity. The reason we’re continuing down the coal path is that at present it appears to be the cheapest option. And the government has carbon capture and sequestration (CCS) down on its list of climate change mitigation options.
We already have a high per capita carbon footprint in this country (about 10 tons a year) because of our reliance on coal for energy and this is despite the fact that 30 percent of South Africans don’t have access to electricity. The country needs to be able to generate clean and affordable electricity to help raise these millions of people out of poverty.
So my question is: Will “clean coal” technology ever be able to do this – and even it it can, will it be too expensive for us people of the South to afford?

Climate change an opportunity for sustainable green growth, says President Motlanthe

Acting now on climate change is an opportunity to overcome the global economic crisis by creating pro-poor jobs and sustainable green growth, South Africa’s President Kgalema Motlanthe said in his opening address at the government’s Climate Change Summit 2009 in Midrand yesterday.
The four-day summit in Midrand is an opportunity for key stakeholders to discuss and agree the framework for a national climate change response strategy.
The climate change challenge in South Africa is ultimately about combating poverty, sustainable development and energy supply, the president said. It is poor communities who have contributed the least to climate change that will bear the brunt of the impacts, he said. The policy frameworks for a transition to a low-carbon economy are an insurance policy against the worst impacts of climate change.
The country’s emissions need to peak between 2020 and 2025, stabilise for the next decade and then start to decrease from mid-century but to do this the country needs a coherent strategy.
Marthinus van Schalkwyk, the minister of environmental affairs and tourism, said: “We cannot allow ourselves to dither at the point when action and implementation are most critical.”
Describing how much had changed since South Africa’s first national climate change summit four years ago, he said that although a great deal of progress had been made, the challenges had become more urgent.
Climate change is now one of the government’s foremost priorities and internationally the message is resounding that climate change is happening now and will get far worse unless we substantially reduce our greenhouse gas emissions immediately.
Action on climate change needs to be seen as an investment in the future, he said. The development of clean and renewable technologies is imperative and holds many opportunities for green investment and green jobs. “Today we know that if we continue without a carbon constraint we face the threat of border tax adjustments or trade sanctions from key trading partners and the destruction of thousands of jobs in the high-emitting trade exposed sectors.”
Thanks to the Long Term Mitigation Scenarios study released last year, South Africa is now aware that if the country does nothing to reduce its carbon emissions and continues on a business-as-usual path, its emissions, which are already relatively high by international standards, will quadruple by 2050 with potentially dire consequences.
He said that local industry must be prepared for a new era in which mandatory reporting of greenhouse gas emissions will become part of the regulatory landscape. The department of environment affairs and tourism “has initiated a process of developing greenhouse gas measurement monitoring and reporting regulations that will shift our work in this regard from a voluntary to a mandatory level”.
He said South Africa is willing to substantially deviate from its business-as-usual emissions trajectories, but the rich countries of the north must take the first steps with deep emissions cuts and financial and technical support for developing countries.
The world needs a strong, innovative, multilateral solution to climate change, said Beki Ntshalintshali, the deputy general secretary of Cosatu. Without that “the main victims of climate change will be the poor (as we have seen in the recent floods in KwaZulu-Natal and Soweto) and workers, particularly in developing countries.”
The challenges of poverty and climate change have to be tackled in a mutally reinforcing manner, he said.
