  • 'Zero Carbon': the Wrong Problem Diagnosis, the Wrong 2050 Metric of Success, for New Zealand and the World
    ‘Zero Carbon’: The Wrong Problem Diagnosis, The Wrong 2050 Metric of Success, for New Zealand and The World. The government surely must agree?: Climate Change is 'merely' one symptom' of ‘The Real Problem’? ‘The Real Problem’ is that Humanity is living well beyond the bioregenerative capacity of the Planet's Ecosystem. (>70% Beyond!) 1970 was the last time the world was in balance, and ever since then the deficit has been steadily increasing without any sign of abating! (This with all the ‘amazing’ ‘Sustainability’ work going on around the world!) The ‘Issue’ is about ‘real’ 'Sustainable Living' and what ‘that’ really means for ‘The World’, a ‘Nation’, and right down to each, and every individual? I'm sure every New Zealander would agree: 'Sustainable Living', and being a 'Sustainable Nation', means: 'We' as a collective, should all be living within our 'fair share' of less than One Planet's, Ecological Regenerative Biocapacity limits? This surely must be, '‘The Ultimate Goal’' of humanity? It's well accepted that anthropogenic Carbon Emissions are a huge contributor to ‘The Real Problem’, but due to the inter-relationship between the Earth's bioregenerative resources, the solution, and particularly when looking to 2050, requires more than a simple, Carbon Emissions, or a ‘Zero Carbon’ focus. (This particularly for nation’s like NZ with strong and diverse Biocapacity Balance Sheets.) At an ‘enclosed system’, global level, a ‘Zero Carbon’ goal may have real relevance in solving ‘The Real Problem’, however, given the huge demographic, and biodiversity diversity between the nations of the world, setting ‘Zero Carbon’ goals at a nation level has the potential to delay, deceive, and confuse efforts to solve ‘The Real Problem’.

  • The Ecological Footprint Emerged As a Response to the Challenge of Sustainable Development, Which Aims at Securing Everybody's Well-Being Within Planetary Constraints
    16 Ecological Footprint accounts The Ecological Footprint emerged as a response to the challenge of sustainable development, which aims at securing everybody's well-being within planetary constraints. It sharpens sustainable development efforts by offering a metric for this challenge’s core condition: keeping the human metabolism within the means of what the planet can renew. Therefore, Ecological Footprint accounting seeks to answer one particular question: How much of the biosphere’s (or any region’s) regenerative capacity does any human activity demand? The condition of keeping humanity’s material demands within the amount the planet can renew is a minimum requirement for sustainability. While human demands can exceed what the planet renew s for some time, exceeding it leads inevitably to (unsustainable) depletion of nature’s stocks. Such depletion can only be maintained temporarily. In this chapter we outline the underlying principles that are the foundation of Ecological Footprint accounting. 16 Ecological Footprint accounts Runninghead Right-hand pages: 16 Ecological Footprint accounts Runninghead Left-hand pages: Mathis Wackernagel et al. 16 Ecological Footprint accounts Principles 1 Mathis Wackernagel, Alessandro Galli, Laurel Hanscom, David Lin, Laetitia Mailhes, and Tony Drummond 1. Introduction – addressing all demands on nature, from carbon emissions to food and fibres Through the Paris Climate Agreement, nearly 200 countries agreed to keep global temperature rise to less than 2°C above the pre-industrial level. This goal implies ending fossil fuel use globally well before 2050 ( Anderson, 2015 ; Figueres et al., 2017 ; Rockström et al., 2017 ). The term “net carbon” in the agreement further suggests humanity needs far more than just a transition to clean energy; managing land to support many competing needs also will be crucial.

  • Population Growth & Resource Capacity
    Population Growth & Resource Capacity Part 1 Population Projections Between 1950 and 2005, population growth in the U.S. has been nearly linear, as shown in figure 1. Figure 1 U.S. Population in Billions 0.4 0.3 0.2 Actual Growth 0.1 Linear Approximation - - - H L Year 1950 1960 1970 1980 1990 2000 2010 Source: Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat. World Population Prospects: The 2010 Revision. If you looked at population growth over a longer period of time, you would see that it is not actually linear. However, over the relatively short period of time above, the growth looks nearly linear. A statistical technique called linear regression can create a linear function that approximates the actual population growth over this period very well. It turns out that this function is P = 0.0024444t + 0.15914 where t represents the time variable measured in years since 1950 and P represents the (approximate) population of the U.S. measured in billions of people. (If you take statistics, you’ll probably learn how to obtain this function.) The graph of this linear function is shown in the figure above. (1) Just to make sure that you understand how to work with this function, use it to complete the following table. The actual population values are given. If you are working with the function correctly, the values you obtain should be close to the actual population values!

Its Ecological Footprint recorded an annual 5% growth till the mid-90s. During the Asian Financial Crisis in 1997 and 1998, both GDP and Ecological Footprint 14 CASE STUDIES dropped. As GDP dropped so did our strain on natural resources. Consistent trends of GDP and Ecological Footprint were seen during the SARS outbreak in 16 CHANGE THE WAY WE LIVE 2003 and the global financial crisis in 2007 and 2008. Since 2009, the economy started to recover, and the Ecological Footprint has worsened ever since. With the continual growth of our GDP, our Ecological Footprint may continue to increase if we adopt a business-as- usual approach. A shift in our daily habits, coupled with support from business and government, can help to stem the runaway consumption that is impacting the habitats and natural resources we depend on.

Futher degradation of the Earth’s capacity to generate resources, continuing accumulation of greenhouse gases and other waste, make likely shortage, or even collapse, of critical ecosystems. Climate debate: Who act first may be at a competitive disadvantage vs the opposite . In an age of growing resource scarcity, the wealth of nations increasingly will be defined in terms of who has ecological assets, and who does not. Rethingking Wealth in a Resource-Constrained World (3) . Without significant change, countries that depend extensively upon ecological resources from abroad will become particularly vulnerable to supply chain disruptions, and to rising costs for greenhouse gas emissions and waste disposal. Countries and states with sufficient ecological reserves to balance their own consumption or even export resources will be at a competitive advantage, ex: BedZed in UK and Masdar in UAE (can operate on small ecological footprint) The Role of Metrics . Clear metrics can help change ideological debates into discussion based on empirical facts. The Ecological Footprint was developed over 15 years ago to help provide just such a metric. Footprint Basics - Overview . Human activities consume resources and produce waste, and as our populations grow and global consumption increases, it is essential that we measure nature’s capacity to meet these demands.
