Natural capital, made up of several elements that nature provides us with as the sustenance and basis of our society (soil, raw materials, water, clean air, …) has an economic value: today any growth model that ignores this by now shared knowledge can no longer work.

Green growth: an operational tool (and GDP has had its day…)

Carlo Carraro, Director | International Center for Climate Governance

Let’s imagine a geography map. Let’s imagine a brown marker placed at one point on the map (the starting point) and a green marker (the arrival point) placed at a different point. The brown marker is brown economy, today’s economy, largely based on the use of fossil fuels and no longer sustainable for the planet and ourselves. The green marker is the point we need to get to, green economy, an economic system where well-being and social equity progress while environmental risks are reduced and the limits to natural resources are managed more sensibly: a low-carbon economy, whose key factors are social inclusivity and high efficiency in the use of resources.

How can we move toward the green marker? There is no single path but many combinations dictated by the choice of different paths, different cruising speeds and different means of transportation. This makes the path toward green economy a creative trek full of possibilities, opportunities and feasible adjustments. The economic and social conditions of different national realities and priorities necessitate adaptation of the transition to the context in which it takes place: while in one place the priority may be to develop green sectors (such as renewable energy), in another it may be to green the brown sectors, or to act on the equity front.

Similarly, the measurement of well-being and growth cannot follow the single index of Gross Domestic Product (GDP), which measures the well-being of a nation solely on the basis of increased production of goods and services, when we know that sustainable development must also consider other parameters better suited to take into account environmental sustainability and social development. How then can green growth be measured?

Moving Beyond GDP – Measuring inclusive green growth” was the theme of the Policy Session organized by the Green Growth Knowledge Platform (GGKP) as part of the 5th World Congress of Environmental and Resource Economists (WCERE), the most important forum of economists of the environment and natural resources, held in Istanbul (Turkey) from June 28 to July 2, 2014. 1,100 economists from around the world gathered to exchange the results of their research, aware of the fact that a good economy does not ignore natural capital but includes it to all effects in their development models. Natural capital, made up of several elements that nature provides us with as the sustenance and basis of our society (soil, raw materials, water, clean air, …) has an economic value: today any growth model that ignores this by now shared knowledge can no longer work, not only in environmental terms but also in economic ones: growth cannot ignore the limits imposed by the environment and by exhaustible natural resources. And in order to take account of these limits it is necessary to set a price on natural capital, correcting negative externalities that distort market behavior, fooling us into believing that we can make unlimited use of nature’s “free” commodities.

Marianne Fay (World Bank) chaired the session, which involved, besides myself, Edward Barbier (University of Wyoming), Geoffrey Heal (Columbia Business School) and Sheng Fulai(UNEP), in addressing the issue of green growth and discussing the role of sustainability indicators both to increase the effectiveness of communication, and to help policy-makers implement concrete, verifiable actions. Sustainable growth is the main activity of GGKP, which started up two years ago as a global network of 30 international organizations and experts, and on whose Advisory Committee I serve. GGKP’s aim is twofold: on the one hand to address the main weaknesses of the theory (and practice) of green growth by promoting coordinated research, and on the other to provide policy-makers, through the right channels, with the information they need to support a transition to a green economy. The third annual GGKP conference, “Fiscal Policies and the Green Economy Transition: Generating Knowledge – Creating Impact”, to be held on January 29-30, 2015 at the Ca ‘Foscari University of Venice, will focus on tax policies: environmental taxes, subsidies for adopting clean technologies and innovation incentives, along with other fiscal instruments, can play a crucial role in promoting a green economy and limiting environmental externalities.

But in order to get the world of politics to use these and other tools, and to get the public to appreciate their usefulness, they must be presented in a proper way. “Numbers not only help us measure, but they also help communicate the challenges we face and the successes we’ve had,” writes Amanda McKee (GGKP) in her web article Measuring green growth at the WCERE. And in this sense GGKP is promoting a new critical study precisely in order to outline a statistical system that goes “beyond GDP” to aid decision-makers in taking account of a far more complex reality, in which GDP is not even the most important variable. Along this direction, the Fondazione Eni Enrico Mattei, by means of a model of the world economy, has constructed the FEEM SI (Sustainability Index), an aggregate forward-looking index, which includes 23 indicators related to social, environmental and economic dimensions. Using this index, it becomes possible to provide projections on future sustainability performances at national and supranational levels. A useful tool to help policy-makers analyse scenarios for predicting the effects that different policies might have on sustainability.

Dear Johannes Hoek and Solimpeks Corp In point 4 of the interview, you claim: "In test reports we can see 28% PV efficiency and 60-70 C degrees hot water". If your pv-module achieves 28% efficiency at STC, or at NOCT, you can almost claim a world efficiency record. If you have a test report documenting this efficiency from a certified EN-test and institution, I would love to see it! According to your data sheet for Solimpeks PowerVolt pv-t module (dimensions: 0.828x1.601m; Wp STC 190) So We module efficiency at STC is: (190 / 1000) x 100/(0.828 x 1.601) = 14.3%. Would be interesting to see if you can substantiate this claim with certified data.

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
