Tourism is the primary source of revenue for the Hawaiian economy. Normally when one thinks of Hawaii, they think of vacation.

Nevertheless, the level. Consider reasons why companies seem increasingly committed to presenting themselves as being sensitive to ethical and environmental concerns words - 7 pages Within recent times there have been concerns with business ethics and environmental issues by a large number of companies. Businesses that would normally not care about these issues have suddenly appeared to have a conscience.

Environmental Problems: Improving the Quality of International Agreements words - 16 pages ideas, to improve environmental education, to address social concerns in relation to environmental degradation, to include previously ignored social groups, and to seek change at a variety of scales of activity. Canada's position internationally should be to promote significant environmental and social values and concerns.

Canada must respect and employ the most appropriate actions and efforts of other nations in the facilitation of environmental. Today, such environmental groups are integral to the environmental movement, representing a traditional means for collective action. Additionally, through the ongoing dissemination of accessible information and knowledge about environmental causes and issues, such organisations cultivate public awareness and attempt to muster support.

The guidelines prescribe exhaustive methods for measuring costs and benefits by stipulating the components of environmental conservation costs and environmental conservation benefits. Accounting Guidelines clearly reveal the concerns of the Japanese Government for allowing the country's development without jeopardizing the environment. How committed is Canada, with respect to environmental security in the international community?

But due to recent research, Canada must be more strongly committed to environmental security due to increasing environmental problems internationally. Also to stay committed to increased access and. The Emergence of Environmental Justice in Literature words - 10 pages Over the past few decades we have seen a gradual increase in the number of writers writing about issues related to environmental concerns. So far poets, fiction writers and nature writers from different communities were either ignored or misread when they tried to raise their voice for environmental justice concerns.

All that is changing now as we see an increasing number of writers exploring issues related to environmental racism and.

Therefore, an additional restriction must be imposed in the following way:. At this stage we have the equations to setup the optimal control problem, but it is reasonable to suppose that physical capital also produces pollution in addition to output.

It is also worth noting that by devoting output to pollution control, the community can lower the amount of pollution generated, refreshing air quality. Note that there is no stock accumulation of pollutant in this model, which is a recognizable shortcoming. But, as in Forster , it can be easily introduced without substantial changes.

Therefore, following Foster , we can formulate an equation for pollution determination as:. Finally, the last equation to consider in order to setup the optimal control problem is the linearly separable utility function, assumed to be a function of consumption C t and pollution P t ,:.

Now we are ready to state the optimal control problem. The objective is to maximize the discounted flow of utility over an infinite time horizon. The problem is to find an optimal path for the variables in order to:. To analyze the solution for this problem, we need to formulate the current Hamiltonian, which in this case is as follows:. We have a similar problem as the one we derived in the last model of optimal capital accumulation in the presence of a depletable resource. The only difference is that the very last two terms in 17 and the fact that transversality conditions do not have a role to play, as stated in Chiang , given the infinite-horizon feature of this problem.

The derivation of the optimal conditions leads to the following equations of motion for the two loci in consumption and capital accumulation:.

Using these two equations we can investigate the behavior of the capital stock in the K t , C t -space in a somewhat mirrored manner we mentioned earlier. The detailed phase-diagrammatical and mathematical analysis for the solution of this problem is presented in Forster The relevant result coming from this optimal environmentally sounded growth model points out that when pollution is accounted for, the production process tends to a lower physical capital stock accumulation than when pollution control is not considered, the same qualitative result attained in our earlier analysis of the depletable natural resource model.

Having presented the two pioneering optimal output growth models accounting for environmental issues, on the one hand, considering exhaustible natural resources, and on the other, pollution as waste generation, we should say that these refinements are important improvements in terms of offering a solid theoretical frame to advise environmental policy in practice.

Surely, at least in terms of considering the introduction of environmental issues, the models discussed above seem to have their relevance for the design and implementation of policy on this matter.

As posed by Auty , introduction of environmental variables into output growth models has helped by "reinforcing the rationale for the sound management of natural resources and also It is true that depletable resources, pollution generation, output production and consumption are all interrelated issues, and thus, to be fully complete such models would have to consider all at the same time. Another set of criticisms refers to the formal and mechanistic manner upon which optimal control models are based.

To deal with environmental issues in a pertinent way, political and institutional frameworks must play a very important role, a feature that the formal analysis of optimal control theory is far from acquiring. A recent contribution considering an institutional framework under an optimal dynamic setup applied to output production is Costantini and Monni Rethinking the main point, it was seen in Section 'Natural Capital and Sustainability: a Qualitative Conceptual Approach' that in order to attain sustainability a pre-requisite is to preserve the total stock of natural capital.

In Section 'Environmentally Based Output Growth Models: an Analytical Apparatus', the analysis of the two pioneering and environmentally-sounded output growth models showed that to control the exhaustion of nonrenewable natural resources or the generation of pollution the rate of production growth has to be reduced. Moreover, it was suggested that it is possible to set up a way allowing for depletion of nonrenewable resources and, at the same time, compensating such environmental damages with improvements upon the available stocks of renewable natural capital, and thus sustainability could be obtained even with no need for reducing an economy's output production.

Many authors have considered alternative ways to exploit natural resources under sustainable rules, as production growth paces its trajectory. Amigues, Favard, Gaudet and Moreaux show that by using the general equilibrium approach, the order of extracting a depletable natural resource is to start with the most expensive one, when renewable substitutes are available.

Holland , in a partial equilibrium analysis, presents an interesting criterion to optimally use natural exhaustible resources taking into account different orders of extraction, not necessarily starting with the most expensive one. Chakravorty, Moreaux et al. They conclude that pollution can be generated, but a ceiling has to be imposed, meaning that the dirty absorption by the clean renewable resource can only start when the ceiling is bidding.

Moreover, Lafforgue et al. Considering these relevant contributions, the two pioneering output production models analyzed in Section 'Environmentally Based Output Growth Models: an Analytical Apparatus', and the definition of natural capital and its related qualitative concept of sustainability developed in Section 'Natural Capital and Sustainability: a Qualitative Conceptual Approach', we can imagine a scenario where, as long as depletion of nonrenewable natural resources is in course, the augmentation of renewable natural resources can feasibly occur, and thus a new perspective on appraising sustainability can be offered, without implying diminishing produced output.

As showed in Section 'Natural Capital and Sustainability: a Qualitative Conceptual Approach', the total stock of natural capital is the simple sum of the stocks of nonrenewable and renewable natural resources. Sustainability is attained as long as the entire stock of natural capital remains into future at least at the same level as it is today. Thus, it is possible to setup a way, based on the theoretical support used, to obtain sustainability, even if we allow for bounded depletion of nonrenewable natural resources.

Therefore, we can list two ways to reach sustainability in the presence of nonrenewable natural resource depletion, but, at the same time, allowing for the accumulation of renewable natural capital: i use part of the prospects earned in production activities that deplete nonrenewable natural resources to increase investments towards or to improve conditions related to the augmentation of the stocks of renewable natural capital; ii follow the criterion above and, at the same time, impose a constraint ruling the rate of extraction of the nonrenewable resource to be always less or at least equal to the rate of regeneration of the renewable natural resource.
