Delighted that both Umdoni and Trashback are being audited in May. Results will be on the web-page as soon as we have them.

Slowly, it seems, that people (some people) are coming round to the idea that it is possible to off-set emissions and do some good at the same time..........

Talk of carbon tax and carbon pricing is - in the general sense - to be welcomed. We need to price in the impact of CO2 emissions to correct market failure caused by negative externalities. But there may be some lessons from Australia.

There was a time in the early 2000's when WWF (SA) were shy of advocacy. Good to see that that has changed. Carbon already has a cost - the 'social cost of carbon' - that is carried by all citizens. The sooner we price it in the better.

At last something from the UN’s High-Level Panel on Global Sustainability. Good to see an acknowledgement of sustaianable development as a process, and a recognition that how we grow economies is more important than growth itself.

A month on, with the spin on both sides having died down, what does a sober look at the facts tell us about what actually happened in Durban and what the implications might be? Viewpoint from Simon Retallack, Strategy Manager, Carbon Trust.

Andrew Light, Centre for American Progress: There are a lot of complaints about the outcome of the UN climate summit in Durban, South Africa, since it ended Sunday, December 11 around 6am after a 36-hour extension.

You can trust George Monbiot to provoke a debate! Lets watch the economic numbers on this technology as they emerge and compare them to those for renewables. Do we really want to go down an alley that is non-renewable at this juncture?

Even by the standards of UN climate meetings, with their jargon, rhetoric and countless committees, when a whole conference overruns by 36 hours something must be up....and note the comments at the end.

Knowing your country's grid factor (the carbon intensity of the energy grid) is essential for any carbon trading project. PACE's long-standing friend Randall Spalding-Fecher has just revisited South Africa's grid factor in this document.

The Canadian government has long complained the Kyoto Protocol is unworkable as it excludes significant emitters

I always enjoy reading the accounts of how these negotiations unfold. To be sure the process is flawed by design, but it seems a little African-Latin American negotiation skill helped in this instance.

UN climate talks have closed with an agreement that the chair said had "saved tomorrow, today".

Agriculture Minister Tina Joemat-Pettersson says the production of raw materials for bio-fuels will not threaten food security.

‘We are on the path to creating liveable, dynamic and lovable urban worlds. This is the COP-17 good news’

Just back for COP17....too early for definitive views, but it was a stimulating and encouraging event in spite of what much the popular media will have us believe. Having been in Copenhagen 2 years ago, I am encouraged by what I heard and saw.
