Carbon dioxide emission footprint calculator and offset estimator. This carbon dioxide emission calculator will help you gain an approximate idea of how many tons of carbon dioxide some of your activities generate and how many trees it would take to offset those emissions - free to use! Webmasters - get this script for your site. Carbon calculator usage instructions Enter the appropriate figures into the quantity column - all fields are optional. If you usually work in metric, there's also a handy conversion feature below. The number of tons of CO2 emissions will be displayed in the right hand column of the carbon footprint calculator. Need to convert from metric? Notes on CO2 emissions footprint calculator: The carbon footprint calculator is not designed to be 100% accurate as there are too many variables required in order to give a reliable emissions total.
Bear in mind that just about all we do in modern life produces a carbon footprint, well over and above what occurs in the natural world. Millennium Ecosystem Assessment. History[edit] During the 1990s, a need was identified by a number of international environmental organisations for a global ecosystem assessment. There had been advances in fields such as resource economics but the new findings had little effect on environmental policy. This led to the launch of the MA in 2001 with the work done over a period of four years.[1] Over 1300 contributors from 95 countries were involved as authors.[2] Findings[edit] The MA gave four main assessments:[3] Over the past 50 years, humans have changed ecosystems more rapidly and extensively than in any comparable period of time in human history, largely to meet rapidly growing demands for food, fresh water, timber, fiber and fuel.
The bottom line of the MA findings is that human actions are depleting Earth’s natural capital, putting such strain on the environment that the ability of the planet’s ecosystems to sustain future generations can no longer be taken for granted.

Water. Outline of Your Area. Outline of Your Area Use a large piece of paper (or any other material to write on), and draw the following information. Use different colours, and make sure you have plenty of space to accommodate all the information of the next steps. What is the basic outline of the local area you want to focus on? What are the most important geographical features (mountains, rivers, lakes, important roads, towns, buildings, etc.)? Maybe, if you are focussing on a town, or a village, you can also distinguish between different areas, such as low and high-income areas, or industrial, agricultural or residential areas. It may then be helpful to go through the following questions for each of these areas individually, as the answers will most likely differ substantially.In order to learn how to assess the boundaries of your system, see system boundaries.

Permaculture : Réalité et Amour de la Terre 1/2. Study: Bioelectricity bests biofuels on miles per acre | Green Tech. Growing plants to make electricity is a more efficient and environmentally sound way to power vehicles than biofuels, according to a study meant to spark a debate over energy policy. The study's authors modeled how far different classes of cars could go based on the available energy from a unit of land and found that bioelectricity--burning biomass to make electricity--far outperforms ethanol.
The paper, published on Thursday in Science, found that bioelectricity delivered 81 percent more distance per unit area of crop land than ethanol. Greenhouse gas emissions per area of land were 100 percent less than cellulosic ethanol. (Click here for PDF of results.) In one example, they found that a small truck powered by bioelectricity could travel almost 15,000 miles compared with 8,000 comparable miles for an internal combustion equivalent. Making electricity from biomass, such as switchgrass, is made by burning the plants to make steam to turn an electricity turbine. EPA's Fuel Mileage Tables.
EJnet.org: Web Resources for Environmental Justice Activists. About | Localcooling. Welcome to the LocalCooling Blog, LocalCooling is a website dedicated to raising awareness through discussion of the latest issues and topics involving the environment. We encourage the community to continue to contribute by commenting, discussing and posting content which is relevant or pertains to posts presented on this blog. We live in a time, where technology is a part of our daily lives, but the price for having this commodity is having the reverse effect on our surroundings. If everybody in the world becomes aware of this fact, and together as a community, we contribute what we can, then the primary goals of LocalCooling would be met.
On this Blog we shall be keeping you up to date with current news of how technology and nature interact with each other and provide you with simple solutions to minimize the effect of pollution on the environment. The LocalCooling movement is taking a new approach towards actively contributing to the environment.

Every day the oceans give us the air we need to breathe; the weather to grow crops; water to support the smallest to the largest animals on earth and 80% of all species; vast ice flows to help regulate our climate; millions of jobs and a life-time of pleasure.
Send us your favourite ocean image and it could be featured here! You and I are alive right now because of the oceans. There is no other place in the universe so full of life as this planet; so green, so rich in diverse, beautiful, weird and wonderful, large and small species, on land and at sea and it is all because Planet Earth is Planet Ocean. They are home to the largest animal our planet has ever known – the now-endangered blue whale - but there are still huge areas of ocean that humans have never seen. More people have stood on the moon than dived the deepest ocean trench and less than 5% of all the oceans have been explored. Energy and environment, clean energy, alternative energy.
