Not 100% renewable, but 0% carbon

I’ve laid my cards on the table in the peer-reviewed literature (e.g., see here, here, here, here, here & here) and the standard media, and I’ve even joined the board of a new environmental NGO that supports nuclear.

And there is hope, despite the ever-increasing human population, rising consumerism, dwindling resources, and the ubiquity of ideologically driven and ethically compromised politicians. I am hopeful for several reasons, including rising safety and reliability standards of modern nuclear technology, the continued momentum of building new fission reactors in many countries, and even the beginnings of real conversations about nuclear power (or at least, the first steps toward this) in countries where nuclear energy is currently banned (e.g., Australia). I’m also heartened by the fact that nearly every conservation scientists with whom I speak is generally supportive, or at least non-resistant, to the idea of nuclear power as part of the climate change solution. An open letter by our colleagues attests to this. In fact, every day that passes brings new evidence that we cannot ignore this solution any longer.

Even despite the evidence in support of implementing a strong nuclear component into climate change-mitigation strategies, one of the most frequent arguments for not doing so is that society can achieve all of its energy needs and simultaneously combat climate change by constructing 100% renewable-energy pathways. While it is an easy mantra to repeat because it feels right intrinsically to nearly everyone with an environmental conscience, as a scientist I also had to ask if such a monumental task is even technically feasible.

Australian Wet Tropics Biosequestration Project

The Wet Tropics Regional Biosequestration Project Development Document was launched last week on the global stage, for public scrutiny, via the Climate Community and Biodiversity (CCB) website. There are only a dozen other cases in the world that have managed to reach this level of scrutiny.

The CCB standards are used in both the voluntary global markets and also for CDM (clean development mechanism) projects (only afforestation and reforestation) that have significant biodiversity outcomes. It is well known that land use, land use change, and forestry provides the most cost-effective means of reducing greenhouse gas emissions globally, and we believe the Wet Tropics project is at the leading edge of showing how.

The Wet Tropics Project is the world’s first regional biocarbon verification case based on community NRM (Natural Resource Management) activities, aggregating different bio-sequestration activities (reforestation, assisted natural regeneration, avoided deforestation, grazing land management, reduced use of fertiliser in agriculture) of myriad landholders in one verification case.

The initiative of using NRM Regional Plan’s as a basis for biosequestration project design is an innovation that can be rolled out across the state and nationally. Using Regional Plans ensures scientifically robust monitoring outcomes because of the adoption of systems already in place for monitoring. Economically the approach allows trading to occur at the regional and landholder level, and sets the stage for new livelihoods in regional Australia in a climate constrained world.

The Wet Tropics Project is itself a pilot for the NRM regions comprising the catchments of the Great Barrier Reef which are pivotal for its the survival. The Wet Tropics Project also helps to inform national policy debates since both Garnaut and the Federal Government’s Green Paper point out the importance of forestry and agriculture but fail to provide any way forward, and are on a watching brief for solutions.

The Wet Tropics initiative with its link to regional plans immediately enables entry into other global developments such as water quality credits and biodiversity credits.
