Hi, I'd like to know if there is a research gap on the implementation of landfill tax as an instrument of environmental policy. Currently, im studying for an M.Sc and looking to study the effectiveness of various instruments (market-based and command and control) of environmental policy, using the hypotheticated landfill tax in the UK as an example of the market-based instrument. Besides, would you please suggest data sets and methodolgies which would be required for a successful study of this. Thank you

Hi! I am building a non-profit organization to support coastal-marine science in Central America. At this time I am studing the international frame that leads coastal-marine science global iniciatives, and also understanding the intalled research capacity in Central America. Could you mention some specific ways that you think could improve the coastal-marine science in Central America? Dou you know persons that I could contact in this same matter? Thank you!

Hi, I saw a video from Guy MacPherson that cited a UNEP report from 2010, which forecasted a >5°C global temperature increase by 2050. 1) Can you confirm this forecast, and possibly link me to the report and/or forecast charts? 2) Can you confirm that this temperature increase is completely incompatible with human life? That a temperature increase of this magnitude is basically the end for human civilization? 3) If 1 and 2 are true, do you have any thoughts about why this information isn't more widely known? This forecast is much more dire than the data most people are currently working from, and you'd think that global human extinction would get more press. Thanks! -Eric

What is your organization's view of the relationship between humans and nature? How does your organization approach the cultural preferences, concerns and traditions of local people when making decisions concerning conservation? Are anthropologists or other social scientists consulted in an effort to gain a better understanding of the local people?

Numerous “green” measures and pledges have been put forward to reduce fossil fuel consumption, but as long as fossil fuels are burnt, greenhouse gases will continue to increase. The reliance on nature to absorb greenhouse gases has proved to be ineffective, resulting in global warming, extreme weather, etc. and we risk exceeding the threshold at the poles. Worldwide, people are still chopping trees and turning fertile lands into paved areas for the expansion of human activities. Forestation is a way to reduce greenhouse gas, but this has only been adopted in small scale and piecemeal manner. To be effective, the scope of forestation should be significantly expanded. Semi-arid undeveloped areas in politically stable and environmental friendly countries should be targeted, and seawater desalination plant can provide fresh water essential for forestation. The crude idea is to build hundreds of desalination nuclear plants to turning Australia into a green continent. Apart from reducing greenhouse gas in the atmosphere, this may help restore the plant and animal kingdoms. Any views to polish, support or condemn the idea are welcome.

How to address the transportation sector? Both freight and personal transport by road is set to increase for the foreseeable future, and even in advanced Denmark they are still building new lanes, highways, bridges and tunnels (eg. the Fehmarn link, partially sponsored by the EU). Even we know building more roads induces more traffic, there seems to be misaligned policies between reducing CO2 emissions and investing in the right transport infrastructure to support that goal. Should we really just accept road- and transport-related emissions a given? Thank you &br Yannick Cornet, Roskilde University, Denmark

I am currently working in Singapore, however, my home country is Myanmar. As one of the poorest countries, there are lots of issues out there to achieve sustainable development in three bottom lines, socio- economic and environmental protection. I suppose our country is on the route of change and at the transitional period. As an environmentalist, I have deeply concerned about the environmental protection associated with people's health and safety meanwhile I absolutely want to see the fast and strong development of economy together with social domain.Having known that it is not easy to sustain a harmonious balance amongst these crucial issues for a developing country, I still want to find out an applicable and workable solution to achieve the task(s). Kindly let me know your advice what is the best approach to reach the destiny of the sustainable development especially at the transitional period. Sincerely, Catherine

In my mind, one big stumbling block to Sustainability is encouraging - persuading - forcing the people in the wealthier nations to be more resource aware, use fewer resources and re-use more. These behaviours have been slowly lost and are not considered 'sexy' by the majority who are more interested (it seems) in the celebrity lifestyle. What strategies would you advise educators and policy makers in getting through this blockage.

Should we be stricter with what is defined as sustainable? How can we call something sustainable when ecosystems, and the services and products that they provide are not mainstreamed within current economic theory? When the monitory value of products is not based within their ecological context (i.e. value of producing the product taking into account ecosystem services, ecological cycles (time, interactions etc..), degradation process, etc..) I am aware of the development of PES however I am sceptical that this will go far enough to address the problem of modern economics. How can we call something sustainable when energy itself is not and will never be sustainable? Unless we come up with a technology that creates renewable energy and the materials for the technology that is needed to produce/convert the energy itself is renewable or at least sustainable, being that the material used to build the technology can be naturally replenished within the life time of the said technology and when expired does not harm the environment when it is degraded/disposed? I think these questions need to be answered before truly using the term sustainable. Without doing so the modern sustainability concept may be in danger of becoming another band-aid to the problems that modern day humanity faces and to the pressures that we are putting on all other species that occupy the planet.

What do you think the role of 2nd generation biofuel will play in emerging markets. For example, biofuel from sugarcane waste serves a much better purpose than fuel from the juice. I think it will revolutionize liquid fuel transportation and provide a great stop-gap for automotive travel.

Firms who manufacture goods often declare zero waste as their policy, rather than an aspiration. When I look further into it, it often means no solid waste going out of their gates or destined for landfill. So they are not including liquid waste (effluents) or gaseous emissions produced from the production lines. Like this the term zero waste is being misused in a veriety of ways. Even governments are starting to declare zero waste as their aspirations. What is zero waste? Is it possible to come up with a consistent definition?

Hi, I would like to know what are your thoughts regarding how viable it is to achieve sustainability in small islands and which do you think that are the necessary steps that need to be taken in order to achieve them. And I have another question, where does the US stand regarding resource efficiency policies? because it is no secret that environmental aspects are not USA's strongest point. Thank You

Dear Sir, Due to non-removal of the aquatic weeds the water level in the water bodies is slowly coming down. Even the ground-water also can be depleted by them. In many cases nowadays, the water bodies like ponds, tanks etc are disappearing due to the excessive growth of such weeds.Hence it affects local temperature also. I also observe that if the weeds are not removed in such water bodies, in a span of many months or years, sand is deposited. In poor countries, people are taking advantage of this and are constructing huts, houses etc THUS MAKING IT IMPOSSIBLE FOR ANY FUTURE REMEDIES. May I know what steps are being taken by the UNEP in this regard? With regards, AMARESH

I am giving a talk to a group of senior business people this coming Tuesday [6th December] and they have asked me to give an overview of how I expect our environment to be in 2060. My feeling are quite frankly quite negative. I was therefore wondering if any experts have written a document expressing their objective view of how they think our environment may be in fifty years time and what they consider are the major aspects that senior business people should consider in their decision making to try to alleviate our impact on the environment. I should be very pleased to hear from you.
