Global Warming & ISO 14001 Standards

It is not difficult to become a believer in global warming. According to the U.S. National Climatic Data Center 2001 was the second warmest year on record and it was the 23rd consecutive year of above normal temperatures. Perhaps most troubling is the fact that the rate of temperature increase is accelerating. Add to this the data just released from insurer Munich Re stating that deaths from natural disasters were more than double in 2001 versus 2000 and insured losses were up more than 50%.UNEP estimates that the extra economic costs of disasters attributable to global warming are running at more than $300 billion annually.

Some 180 countries are proceeding toward an expected ratification of the Kyoto Protocol by the end of this year. Of the six gases it will control CO2 is by far the largest contributing nearly 90% of the global warming impact. The primary source of CO2 is the burning of fossil fuels. Therefore the focus on energy will continue to increase.

Throughout the world different methods are being used to encourage reduced energy use. Japan has enacted the Energy Conservation Law in 1999 mandating huge efficiency improvements by 2004 for nearly all air conditioning products. The U.S. has revised ASHRAE Standard 90.1 for buildings to raise the minimum COP level for centrifugal chillers from the current value of 5.2 to 6.1 effective in October 2001. DOE and Green Seal have revised their recommended efficiency levels to an even higher level of 6.27.

Some countries use laws. Others use codes and standards. An increasing number of countries are using environmental costing which increases the price of energy thereby increasing the financial attractiveness of high efficiency products. European countries have been using such “carbon taxes” for more than a decade. However a rapidly growing trend in developing countries is the reduction of subsidies to energy industries “so prices more accurately reflect environmental impacts” according to OECD’s Environmental Strategy for the First Decade of the 21st Century.

China has shown leadership by reducing subsidies to the coal industry from $24.5 billion in 1990 to $10 billion in 1996 resulting in 7% emissions reduction while seeing a solid economic growth of 36%! China is now moving aggressively into environmental costing with the just announced (1/13/2002) 5-year environmental plan that commits 700 billion yuan ($84 billion) to help protect the environment. The government will provide the fist 65 billion yuan to initiate the project but will apply the “polluter pays” principle for the rest. The “environmental protection authorities will collect funds from the pollution-producing companies”. The impact on the price of energy is not known at this time. However it is clear that the addition of environmental costing will increase energy prices. According to a European Research Commission Report of July 2001 “The cost of producing electricity from coal or oil would double if costs such as damage to the environment and health were taken into account”.

The global movement to high efficiency is accelerating just like the rate of temperature increase. But this is not all that is changing. This second environmental threat of global warming is making it clear that we need to give combined consideration to ozone depletion and global warming. But more important is the need to focus on the real issue which is the total environmental impact not address each individual environmental threat in isolation. This includes the concept of environmental risk exposure, which recognizes that there are other environmental threats that are less well understood today. However, there are “no regrets” decisions we can make today (such as minimum refrigerant charge, minimum atmospheric life refrigerants, etc.) to minimize these risks.

Combined consideration would place more emphasis on reducing the use of CFCs, which are still being produced in developing countries until 2010 in accordance with the Montreal Protocol. Little attention is being given the large contribution to global warming from CFCs. Actions which cause confusion and delay the phaseout of CFCs cause increased environmental damage rather than lessening the environmental impact.

The other rapidly changing factor in the HVAC industry is the shift to becoming a hermetic industry, where refrigerant is contained throughout the life of a chiller and recycled for further use when the chiller is replaced. This simple understanding that “if it doesn’t get into the environment it does no harm” is a powerful argument, which will lead to the continued use of the most efficient refrigerants in such closed hermetic applications as chillers. In just 15 years annual refrigerants emissions from chillers have been reduced from 25% to well below 1% today. This defines a whole different world than that which existed when the Montreal Protocol was crafted some 15 years ago.

But perhaps the most important change coming to our industry is the realization that there are no new or “perfect” refrigerants waiting to be discovered. There are eight elements that can be combined for use in a vapor compression cycle. All feasible combinations of these eight have been evaluated. The reality is “what we have now is all there is”.

This recognition is why we are now seeing a shift from the search for a perfect refrigerant to a search for the right refrigerant(s) for the right application. Said another way, the highest efficiency refrigerants for the lowest emissions applications. Many in our industry call this “Responsible Use”.

Demographers now project that, in the near future, more people are going to live in cities than in rural areas, and this will be the first time in the history of the world that this has been the case. As a result, while there are many different levels of society and business where global warming needs to be dealt with, cities are going to take an ever expanding role. It’s easy for local governments to pass the buck to state, provincial, or national governments, but this isn’t a sustainable practice. If we’re going to successfully fend off the apocalyptic-scale global warming that many scientists now predict, cities are going to have to take the lead. As a start, here are some basic things that municipal governments can do.

Green roofs: If you fly over any major metropolitan area, you’ll likely see a few patches of green where there are parks or tree-lined streets, but for the most part you will see nothing but bare rooftops dominating the landscape. When you think about it, that’s a lot of space that is simply going to waste. In the city of the future, we’re going to increasingly put all this excess space to use for green purposes. There are a few things we can do up there, including:

• Having solar and wind power stations on roof tops can help make buildings and cities in general cleaner and more energy efficient.

• Rooftop gardens can help residents grow their own produce rather than having to buy from energy-inefficient sources.

• Rooftop trees and greenhouses help balance out deforestation while cleansing smog-filled urban atmospheres.

Expanded public transit: When it comes to moving people around, the private automobile is the most energy-inefficient vehicle ever created. Things like buses and trains are not without emissions, but they have a much lower pollution-per-person ratio. Many cities throughout the developed world are decades behind in this respect and need to catch up fast in order to do their part. We need more rail-based transit systems, and many cities would do well to expand their bus networks.

Pedestrian and bicycle infrastructure: In many cities, it’s a sad state of affairs for pedestrians. If you want to travel on foot, you too often have to deal with landscapes that make walking very difficult, not to mention the culture of motorists who drive fast and aggressively and are not used to sharing the road. For a more sustainable future, we need more pedestrian-friendly landscapes, and it also doesn’t hurt to encourage people to take their bicycles.

Better recycling programs: We have come a long way in the realm of recycling, but too many cities are still stuck in the 90s with their recycling technology. We now have the ability to recycle a much broader spectrum of materials, including plastic bags and soiled containers, but many cities haven’t taken the steps necessary to implement these technologies. This investment, which is relatively small in the big picture, can have hugely positive effects in the long run.

Fuel-efficient fleets: Most cities rely on large fleets of vehicles to provide their basic services. From buses, to sanitary trucks, to road maintenance equipment, all of these vehicles can be made more efficient with new technology. Of course, it costs a lot of money to replace these vehicles, but all vehicles do need to be replaced with newer models sooner or later, and cities should use these opportunities to make their investments more efficient, rather than purchasing the same old polluting vehicles.

As individuals, each of us can contribute to the solution. As a start, we can choose to drive vehicles that are more fuel-efficient. We can plant more trees. We can recycle where practicable. We can take stock of our energy consumption practices and try to reduce them by some factor.

But, what steps can your organization take to help? The answers are varied, depending upon the size of the organization and the related environmental aspects and impacts. But no matter how simple or complex the business, each can benefit from the implementation of a management system based onISO 14001:2004. This international standard has as its focus the prevention of pollution, accomplished by a teamwork approach to identifying those aspects of the organization’s processes that have the potential for harming the environment and the development of ways to reduce or prevent this harm. In the process, many organizations have found ways to reduce costs by elimination of scrap, changes to their waste disposal processes or reduced use of natural resources. It is the application of the system approach that has proven to be successful. And, once the system is in place, it is logical and beneficial to have that system certified and registered. This provides added assurance that the management system remains effective and also provides public recognition to numerous stakeholders that your organization is committed to the prevention of pollution.
