How Permanent Are Carbon Offsets



Author : James Nash

Something that worries many people about offsetting emissions with trees is how can you guarantee that they will last long enough? Trees take time to absorb carbon, extracting it slowly from the atmosphere as they grow But saplings are vulnerable to bad weather, neglect and damage by animals Older woodlands and forests face the risk of fire, pests and disease, which could release the carbon back into the atmosphere And how can we be sure even if a forest is protected now, it won’t be logged or cleared at some point in the future?

Because some offset schemes have been poorly run, with saplings dying or other problems, many people have concluded that it is impossible to guarantee the permanence of trees But failed schemes shouldn’t blind us to the fact that humans have been successfully growing trees and managing woodlands and forest for thousands of years However, climate change is too grave and urgent a problem for us to afford to waste time and resources on efforts that will fail to deliver Nor should we forget that forestry-based schemes tend to be remote, and most purchasers of offsets will never see the trees they are funding nor the carbon they are saving, so there is a vital issue of trust and credibility

What we need is a realistic assessment of the risks, and reliable ways to ensure permanence

But first we should note that permanence is not an issue unique to forestry-based offsets Wind turbines or hydro power generation facilities can break down Villagers can reject more efficient stoves brought in through an offset project and return to traditional carbon-intensive ways of cooking, and so on There are risks with all forms of offsetting (Although one unique aspect of forests is that they can regenerate of their own accord, and recapture lost carbon )

And while we need to take the risks seriously, we also must not exaggerate them The risk of fire, for example, varies enormously with where the project is based, the types of trees used, forest management procedures, etc In the Pacific Coast forests of the northern US and Canada, the average frequency of fires is in the order of hundreds or thousands of years Meanwhile, the Scandinavians and others have devised effective fire control regimes Many of the risks of tree planting schemes can be minimised at the design stage by planting in low fire risk areas, by using disease-resistant species, and taking steps to minimise pests, etc Schemes based on preventing deforestation should include steps to reduce the possibility of these threats especially where humans are active near forests

But, no matter what we do, there will always remain an element of risk Forest ecologists, in fact, regularly quantify the frequency and severity of damage from fire, pests and disease for different forest types Companies growing trees for commercial purposes, and public organisations protecting and managing natural forests and woodlands, regularly use this information in their planning We can also use this information to estimate how much of a forest or plantation might be lost over a given period of time, and discount it when calculating a carbon offset

There are a number of other techniques we can use to mitigate the risk of trees being destroyed, or to compensate for the risk Insurance is an obvious one There are already specialised insurance products for commercial forestry and these could possibly be adapted for carbon offsetting Liability agreements are another, where the buyer and seller make a legally binding agreement to replace any carbon credits lost through fire, disease, etc

Another approach would be to pool the carbon credits from a number of schemes, and hold a certain portion back in reserve should there be damage to one of the projects This a bit like banks having to hold a certain amount of capital in reserve to cover their market and credit risks

Other steps can be taken to reduce specific risks For instance, if there is a danger that local people could damage a forest in a quest for firewood, they could be provided with other sources of fuel, or more efficient cooking stoves, or part of the forest could be set aside for producing firewood sustainably

Humans are good at managing risks It is one of the factors that makes us such a successful species There is much that we already know about managing risks in general –and those of forestry in particular– that we can bring to bear in operating carbon offset schemes If we factor the risk of impermanence into our calculations, we not only make our offset schemes more robust, we make them more credible as well

Adding interest to your garden with a garden pond or water garden is a great idea, and one of the first things you should look at is a top-notch water garden filter system that can do the hard work for you

Highly chlorinated water kills the microorganisms that are found it in the soil The unfortunate part about the previous statement is that those microorganisms are there for a reason It is their task to protect the plant and the source where it gets its food

This is the very reason why home gardeners steer clear of chlorinated water They prefer a healthier choice – cleaner water By getting a filter system for their garden water, 85% of the chlorine from hose water is removed

The water from garden filter systems are also beneficial for bathing dogs Children can also have fun with the sprinkler In fact, it can also be used to wash cars

Water garden filter systems are necessities for gardening You have nothing to worry about because they are completely non-toxic Why would we suggest that this be the same water you used to your pets, children and car, if it were?

Now, let us say that you have a man-made pond in your garden This filter system can also clean the water there Not only will it do that, it will also protect the soil ecosystem in your pond

Imagine the beneficial insects you could have killed if you thoroughly cleaned your man-made pond using chlorinated water At least, with a filter system, the 20,000 to 40,000 gallons of water are 100% clean

Just like any electronic appliance, water garden filter systems can be recharged The filters can also be replaced in due time – when it has acquired all dirt from the pond and needs to be changed

Choose a filter system that comes with the hose protector In that way, maintaining it will be a whole lot easier There are systems that already include a pre-filtered hose This is to control the flow of the water better

Most home gardeners ask why they should remain chlorine in their garden Obviously, you would want to keep the beneficial insects in the natural ecosystem Chlorine kills living organisms like bacteria and fungi but at the same time, it also contaminates the water source Chlorine is harmful to your plants primarily because they depend on these organisms to stay alive

Plants survive because they receive the nutrients they need from the soil and water A healthy soil is composed of molds, fungi and bacteria (which chlorine is designated to kill ) Gardeners and farmers know that in order to protect their plants and the ecosystem from the pesky pests, diseases and insects is by using beneficial bacteria

By using chlorinated water, the microorganisms that were placed in the soil to protect the plant and the plants food source in the first place will also be killed Thus, horticulturists and farmers do not use chlorinated water when they irrigate their crops

Thanks to the water garden filter system, water is dechlorinated This is a better and healthier option because water garden filter systems clean the garden and save the beneficial bacteria through out the process

Water garden filter systems turns chlorine into chloride that is completely harmless This redox procedure is their basic principle on how they can assure their consumers that the water coming out of the system is totally chlorine-free

So after watering your garden with the chlorine-free filter system, throw in a bath for our dogs In fact their coats can become softer and finer from the brittle and dryness it had been due to sun and chlorine exposure

You can also let your children have fun all summer long with the garden hose feature attached to your water garden filter system They can even swim in a pool that you filled using the filter system If you are an automobile fiend and the usual wax is not enough to give your “baby” the sparkle and shine it deserves, switch to dechlorinated water that you can obtain from the water garden filter systems

From the original purpose of providing chlorine-free water to your garden, water from filter systems has escalated to new heights

Saving On Fuel Resources In Massachusetts



Author : Beth Olignerf

As gas prices go up and then back down, no one ever knows where they are going to be going next Oil is a precious resource, and although it sometimes feel like it is going always be there, if we continue to over use this resource, the demand will go up while the quantity goes down The best way to ensure we continue to have gasoline is to work to conserve it whenever possible Massachusetts’ officials have tips on how to save on gas

The first way is simply to bike instead of driving around all the time Biking has many benefits First of all, since you are not using gasoline, you are not spending money on that Second, since bikes don’t use gasoline, you are helping the environment by not contributing to greenhouse emission A third reason to ride a bike is to get exercise With many people working jobs that keep them pretty stationary, their only exercise for the day might come from the exercise they get biking to and from work Biking helps people to lose weight and stay healthy

Carpooling is another great resource that cuts down on greenhouse emissions and on gasoline usage Massachusetts residents are encouraged to find people with whom they can form a carpool to get to work and/or school They even have a web site and a phone number where you can connect with people who work and live near you This will help people to form carpools since about three out of four of Massachusetts’ commuters drive alone MassRIDES is a great resource which can save time, money, and gasoline The less people on the road, the less greenhouse gases we have to worry about, and the faster people can get to and from their destinations

Another resource provided by the state of Massachusetts is their Massachusetts Bay Transportation Authority Massachusetts’ public transportation includes subway, bus, train, or boat transportation On the website, patrons can plan their trip schedule ahead of time They can also sign-up to get alerts of service delays and interruptions in the schedule To combine some fuel-saving resources, people can even ride their bikes to subway station or the local bus station and ride public transportation from there

Another way Massachusetts residents can save money is by vacationing closer to home This might sound simple, but often areas close to home provide an enjoyable time that residents have never enjoyed before Often people think that getting away from home is where they are going to have fun, but enjoying what Massachusetts has to offer will save people gas and will help the local economy

Of course, there are other ways that you can drive just as much as you currently do now and still save money on gas An important resource you can use is a tire pressure gauge Make sure your tires are properly inflated If they are not, get them that way Tires that are under inflated will not give you as good of gas mileage, and they can cause a safety hazard Removing excess weight from your car is another way to save on gas mileage The golf clubs you used last weekend can now go in the house instead of traveling back and forth to work with you It can save you a few cents a gallon on gasoline just by eliminating that added weight from your car A final way people can save money on gasoline is by using cruise control on cars that have it
