The new economy of nature :can carbon credits save the planet?
篇一
Carbon credits have emerged as a promising solution to combat climate change and reduce greenhouse gas emissions. The concept behind carbon credits is simple: companies and individuals can offset their carbon footprint by purchasing credits that represent a reduction in greenhouse gas emissions elsewhere. This market-based approach has gained traction in recent years, as governments and businesses seek to meet their environmental targets.
One of the primary benefits of carbon credits is their ability to incentivize emission reduction projects. Projects such as reforestation, renewable energy development, and energy efficiency improvements can generate carbon credits that can be sold on the market. This creates a financial incentive for companies to invest in sustainable practices and technologies. Furthermore, the revenue generated from selling carbon credits can be reinvested into further emission reduction initiatives, creating a positive feedback loop.
Carbon credits also provide a mechanism to transfer funds from developed to developing countries. Developing countries often face significant challenges in transitioning to low-carbon economies due to limited financial resources. By purchasing carbon credits from projects in developing countries, developed nations can support sustainable development while offsetting their own emissions. This not only helps reduce global emissions but also promotes economic growth and poverty alleviation in developing nations.
Another advantage of carbon credits is their potential to drive innovation. The market for carbon credits creates a demand for innovative solutions to reduce emissions. This encourages companies to invest in research and development, leading to the development of new technologies and practices. For example, the demand for carbon credits has spurred the growth of the renewable energy sector, resulting in advancements in solar and wind technology.
However, carbon credits are not without their criticisms. Some argue that carbon credits allow companies to continue emitting greenhouse gases without making significant changes to their operations. This is known as "greenwashing," where companies use carbon credits as a way to appear environmentally friendly without actually reducing their emissions. Additionally, the effectiveness of carbon credits in achieving long-term emission reductions is still a subject of debate. Critics argue that carbon credits may simply shift emissions from one location to another, rather than reducing overall emissions.
In conclusion, carbon credits have the potential to play a significant role in the transition to a low-carbon economy. They incentivize emission reduction projects, facilitate financial support for developing countries, and drive innovation. However, it is crucial to address the concerns surrounding greenwashing and ensure that carbon credits are used as a complementary tool alongside other emission reduction strategies. With careful regulation and oversight, carbon credits can contribute to the global effort to combat climate change and build a sustainable future.

The new economy of nature: exploring the potential of ecosystem services
Ecosystem services refer to the benefits that people obtain from nature, such as clean air, fresh water, and fertile soil. These services are essential for human well-being and economic prosperity. However, they are often undervalued and taken for granted. The concept of ecosystem services offers a new perspective on the value of nature and its role in the economy.
One of the key ideas behind ecosystem services is that nature can be seen as an asset that provides valuable resources and services. For example, wetlands act as natural water filters, providing clean water for human consumption. Forests play a crucial role in carbon sequestration, helping to mitigate climate change. By recognizing the economic value of these services, policymakers and businesses can make informed decisions that incorporate the long-term benefits of nature.
The concept of ecosystem services also highlights the interconnectedness of ecological systems and human well-being. A healthy ecosystem contributes to a stable climate, clean air, and improved water quality. These benefits, in turn, support human health, agriculture, and economic productivity. By protecting and restoring ecosystems, we can ensure the continued provision of these services and avoid the costs associated with their loss.
One of the challenges in incorporating ecosystem services into economic decision-making is the lack of market mechanisms to capture their value. Unlike traditional market goods and services, ecosystem services are often not traded in the marketplace. This leads to their underrepresentation in economic models and policy decisions. However, there are efforts to develop market-based approaches, such as payments for ecosystem services, to incentivize the conservation and sustainable use of natural resources.
Furthermore, the concept of ecosystem services raises important questions about equity and justice. The benefits of ecosystem services are not evenly distributed, with marginalized communities often bearing the brunt of environmental degradation. It is crucial to ensure that the benefits of ecosystem services reach those who need them the most and that decision-making processes are inclusive and participatory.
In conclusion, the concept of ecosystem services offers a new framework for understanding and valuing nature's contributions to human well-being. By recognizing the economic value of these services, we can make informed decisions that promote sustainability and long-term prosperity. However, there are challenges to overcome, such as developing market mechanisms and addressing equity concerns. With concerted efforts, we can harness the potential of ecosystem services to build a more sustainable and equitable future.

The new economy of nature :can carbon pay for nature conservation?The case of the Hong Kong Country Parks
Abstract： The Country Parks of Hong Kong occupy 40% of the total landmass of Hong Kong, and consists of vast areas of secondary woodlands, scrublands, grasslands and reservoirs. That vegetation - and the soil underneath-subtract carbon from the atmosphere, which has a market value. The aim of this paper is to estimate the value of that carbon, to assess whether that value would be sufficient to pay for the upkeep of the Country Parks, and to compare that value to the costs of alternative ways to reduce atmospheric carbon dioxide. To do this, we compare the land ver of1978, 1991, 1997 and 2004 using remote sensing, and identify the three predominant land covers" (woodlans rublands, grasslands). We then estimate the amount and value of the carbon .sequestered by the vegetation and soil of the Country Parks, and compare it to the budget available to the Agriculture, Fisheries" and Conservation Department to run the Country Parks (HK$234 million in 2009/2010). We extrapolate our results over 50 years, from 1978 to 2028. We conclude that by 2028 the carbon sequestered would be valued over HK$800 million, but the value of the additional carbon subtracted yearly would only cover approximately 7% of the total budget needed to run the ountry Parks. We also conclude that because of the large budget allocated to the Country Parks, alternative methods of carbon sequestration - represented by the EU ETS price of carbon - are much cheaper. 作 者： Claudio O.DELANG 作者单位： Department of Geography and Resource Management, Chinese University of Hong Kong, Hong Kong, P R.
