  • Carbon offsets are an innovative tool for allowing companies and individuals to reduce greenhouse gas emissions beyond what they can easily achieve on their own. In the past two years, interest in carbon offsets has grown dramatically as companies and concerned consumers have sought ways to help mitigate climate change. However, the global market for voluntary carbon offsets is currently unregulated, which has led to growing concerns about whether buyers are really getting what they are paying for.

  • Scientists predict the earth is facing 40-to-60 years of climate change, even if emissions of carbon dioxide and other global warming gases stopped today. One inevitable consequence of the greenhouse gases already in the atmosphere will be an increase in the frequency and severity of natural disaster events. Global Warming, Natural Hazards, and Emergency Management documents the imperative need for communities to prepare for the coming effects of climate change and provides a series of in-depth, road-tested recommendations on how to reduce risks for communities and businesses.

  • Elements of present-day sea use management have evolved over a long period. Basic to these are the principles of freedom of the seas, open access to resources, and sectoral management. There is, however, a necessary corrective to this Euro-centric view when the relationships between people and the marine environment are examined in several other cultures. Open access in Western society has experienced more recent restrictions as resource scarcities have arisen and new technological capacities have increased.

  • After the advent of green revolution, more emphasis is laid on the quality of the product along with the quantity of production to meet the ever- growing food requirements. Both these demands can be met when the environment for the plant growth is suitably controlled. The need to protect the crops against unfavourable environmental conditions led to the development of protected agriculture.

  • Greenhouse gases such as CO2 and methane are believed to contribute to global warming. Dust is a common problem throughout all mining activities. Dust generated by vehicle traffic can be reduced through a variety of means. Where water resources are not limited, regular watering with mobile water trucks or fixed sprinkler systems is effec- tive. Otherwise the application of surface binding agents, the selection of suitable construction materials and the sealing of heavily used access ways may be more suitable.

  • It is widely accepted that a modal shift towards railways can contribute to meeting EU targets on climate protection and reducing greenhouse gas emissions. A stronger role for rail will help to achieve real progress towards the 2020 target of a 20% cut in the EU’s greenhouse gas emissions. However, concerted action must be taken by governments and policy-makers to help bring this about. The rail sector is doing its part, having already agreed on a voluntary target for 2020, to cut its 1990 levels of specifi c emissions by 30%.

  • In the future, the domestic voluntary carbon offset market may be largely superseded by a mandatory U.S. trading program for greenhouse gas emissions. Even if it is, there may be grounds for government oversight of the voluntary market today. Oversight may be desirable, for example, to protect consumers and the public interest, to allow learning for regulators, and to provide greater certainty for investors.

  • The debate on climate change has shifted dramatically in recent years. There is now unequivocal scientifi c evidence – summarised in the 2007 report from the Intergovernmental Panel on Climate Change (IPCC) – that global warming is happening; that human actions are responsible; and that this poses an enormous threat to life on Earth. Politicians, businesses and the public are increasingly aware of the problem and are calling for urgent action to cut the man-made emissions of greenhouse gases (GHGs) that cause climate change, in particular carbon dioxide (CO2)....

  • Even in the northern hemisphere, where the impact could be less than elsewhere, the effects from a rise of two degrees will be felt by every town and city. As more and more of the world’s population crowds into cities, the urban environment needs to become a better place to live: a place that improves health, well-being and economic prosperity while simultaneously – and dramatically – reducing greenhouse gas emissions. This means re-designing how we think and how we organise our lives. It requires courage, vision and leadership.
