I live-blogged the entire panel discussion (see here) which included a lively question and answer session. The other panelists included Charles Kolstad of UC Santa Barbara; Ali Sayigh of WREN, and moderator Curtis Brainard of Columbia University.
Jorma Ollila: I will address the question as to whether it is possible to decarbonize in a viable way.Ollila also responded to questions from the audience. See my post Technology and innovation: Climate change Rx?
I will assume technological innovations can be successful. Let's assume that is the case. I'm clearly not wanting to minimize the vast challenges that lie ahead. In fact, the more daunting challenge is to manage how we produce energy and allow a raise in living standards.
Developed economies have used up the atmosphere's capacity to absorb CO2; now developing countries are entering a phase where their need for energy is becoming intensive.
Let's acknowledge three truths:We need to obtain as much energy as possible from renewable sources -- and more. We need to strive toward fewer emissions in a "business as usual" pattern. Business-as-usual means that emissions would double by 2050. But in reality we can't continue to consume more than the current level. An 80 percent reduction from current levels is a reasonable goal. Thus, these two alternatives lie ahead. One is socially and morally unacceptable.
- The demand for energy will continue to surge.
- Energy supply will struggle to keep pace.
- There will be increasing climate stress based on the current consumption pattern.
Therefore, policies and incentives must be put forward so we get it right.
Firstly, we need a cap and trade system that a puts a cost on emissions, that credibly commits us to a path of energy reductions by creating incentives to cut emissions.
Second, we need government support for changes. Government support is critical over the course of next decade -- to deploy by 2020s. We have it in the lab, we do not have commercial projects. This process is not viable without the right kind of government support.
Looking at the Obama government's actions, related to the stimulus package: I see significant and commendable R&D support. Europe took some significant decision earlier this spring -- the US will go there too I understand.
The points are mutually reinforcing, not exclusive. Emissions caps will become more popular as costs get reduced of meeting caps.
In addition to policy angle, there is a geopolitical angle: significant change with regards to emerging markets. Advanced economies must lead by example. This will necessitate resource transfers from developing to emerging markets. But transfers from govt to govt are problematic. Consider the position of a US political leader who proposed such a transfer. He would face political problems.
Cap and trade is a politically feasible way to make the transfers. CDM is a license to do arbitrage -- create opportunities between developed and developing economies. [Jotman: Clean Development Mechanism (CDM) "is an arrangement under the Kyoto Protocol allowing industrialised countries to invest in projects that reduce emissions in developing countries as an alternative to more expensive emission reductions in their own countries."] HFC reduction projects, for example. [Jotman: "by destroying the HFCs factories can earn carbon credits"]
Pace of change is limited by the trillions of dollars tied up in US capital investments. For example, a car lasts 20 years. A power plants last 40 years. To speed up the pace of change would mean premature scrapping of capital investments. In the recent Shell Energy Scenarios, that is. [Jotman: presumably, by scrapping investments prematurely you waste a certain amount of energy].
Blueprints: The projected climate outcome would require stabilization at 650ppm in the second half of century. Renewable energy would consist of about 60% of energy. CCS on all new power plants 2020 (West) and elsewhere (2030). That's based on Shell and MIT modeling. Clearly we need this kind of scenario at a minimum. We need better, but we face severe constraints.
Hence the need to increase pace of policy reform.
