Into ecological overdraft

Globe07In the final chapter of Hot Topic, I refer to the concept of global overshoot: the idea that human activities are exceeding the planet’s ability to regenerate resources. It’s the ultimate meaning of sustainability – living within our planetary means. This year we started eating into our ecological overdraft on October 6th – three days ahead of last year, and the best part of month earlier than in 2000. The Global Footprint Network calculates Ecological Debt Day:

As humanity’s consumption of resources increases, Ecological Debt Day creeps earlier on the calendar. According to current calculations, humanity’s first Ecological Debt Day was December 19, 1987. By 1995 it had jumped back a month to 21 November. In 2007, with Ecological Debt on October 6, humanity’s Ecological Footprint is almost thirty per cent larger than the planet’s productivity this year. In other words, it now takes more than one year and three months for the Earth to regenerate what we use in a single year.

Biofuels to fly, and other stories

747Air New Zealand is carefully positioning itself as a climate-friendly airline with its latest announcement that it is to trial biofuels in a 747 flight from Auckland in the next couple of years. Working with Boeing, Air NZ will be part of the first commercial trial of biofuel, in a Rolls-Royce-powered jumbo in the next 18 months . The flight will only use biofuel in one engine, and will not carry customers. [Stuff, Herald, BBC, June HT blog on aviation biofuels].

The business of climate change

New York-based merchant bank Lehman Brothers have produced an excellent overview of the business and economics of climate change (PDF). If you have any interest in the economics of dealing with climate change, and want an informed overview of the drivers of political and commercial change, this is a very good place to start. I don’t agree with everything they have to say (they’re far too dismissive of electric vehicles, for instance – I reckon EVs have the potential be a disruptive technology), but the sectoral and country by country analysis of investment opportunities is fascinating, and their general take on the issue is very close to my own. From the conclusions:

The size of the carbon market globally, as measured by the value of permits issued, could, on a conservative estimate, be over $100bn by 2020 or thereabouts. This assumes that the United States, Japan, and China join the EU in moving to an emissions trading scheme covering around 50% of their total emissions. Annual turnover would be a multiple of that figure. This compares with the US Treasury market which currently stands around $2 trillion.

They put the chances of an international deal including China and India at 75% (up from 50% in an earlier report), and expect share prices to begin to track relative carbon intensity – with carbon-light companies doing better. Recommended reading.

Cranky about the ETS

 Wp-Content Uploads 2007 08 HomerOur little band of climate cranks couldn’t let an opportunity as big as the NZ Emissions Trading Scheme announcement pass by unremarked. And they didn’t. First out of the blocks was Bryan Leyland, “€œchairman of the economic panel of the New Zealand Climate Science Coalition”, pre-empting the ETS announcement to complain about the government buying offsets for ministerial travel with a press release headed “€œIs your carbon tax really necessary?”

“€œIf there is no evidence of man-made warming in New Zealand – and in the world – this whole charade of cap and trade, and offsetting ministerial travel emissions, should cease forthwith before any more damage is done to our internationally fragile economy.”

Leyland’s views were echoed a couple of days later by a release from Owen McShane, “€œchairman of the policy panel of the New Zealand Climate Science Coalition” (the NZ CSC appear to have enough panels to decorate a small stately home)…

NZ emissions trading scheme announced

NzetsDetails of the government’s planned emissions trading scheme (ETS) have been announced. Scoop has all the government speeches and press releases. I’m reading them at the moment, and will comment more later, but here are some highlights:

  • Foresters will receive the full value of carbon credits on new growth (from 1/1/2008) in post-1990 forests.
  • Agriculture will not be brought into the scheme until 2013.
  • NZ emissions units will be Kyoto-complaint and internationally tradeable (subject to some limits).
  • Some units will be allocated free, others auctioned.
  • Forestry will be first into the scheme in Jan 2008.
  • Transport’s next, in 2009, basically through fuel prices
  • Stationery energy (power generation) and heavy industry will enter in 2010, with no free allocation for electricity generators.
  • Farmers will get free allocation of units based on 90% of 2005 emissions, but details to be worked out

The government hopes that 90% of power generation will be from renewable sources by 2025. In transport, they want to cut per capita emissions in half by 2040, and encourage the wide use of electric vehicles. Goals for agriculture are more nebulous: to be the world leader in emissions reduction research, and to lead the world in agricultural emissions reductions. In forestry, they would like a net increase of 250,000ha in forest area by 2020.
The government has also released an update on our expected Kyoto deficit – up to 45.5 millions tonnes from 41.2 mT, mainly from increased dairy production. In the absence of any emissions reduction policy, the government projects this could rise to 65mT, but believes the ETS will cut the 2008-12 deficit to 25mT.
My first thought? Politically astute. By getting foresters on board with what amounts to a taxpayer subsidy, they get enough trees planted to offset a large chunk of the Kyoto liability, and buy time to bring agricultural emitters in to the scheme. More later.
