Our mission is to:
- Provide Free Resources for Individuals and Organizations to Measure and Lower their Emissions
- Give Access to Most Cost-Effective Carbon Offset Projects to go Carbon Neutral Now


You can also utilize the EPA spreadsheets to obtain a more precise estimate of your carbon footprint.


The Emission Reduction Program for small businesses gives customisable templates which are easy to use.


Offset Certificates finance verified projects that help to slow down the rate of global warming.
Climate scientists are warning that we may soon hit the point of no return where climate change becomes irreversible no matter what actions we take.


Measure
We provide information and resources to help people and organisation quickly and easily measure their carbon footprint.

Reduce
Giving people and companies information on the choices they can make to reduce their emissions and lower their carbon footprint

Offset
Helping people with information on the most cost- effective certified projects from different regions around the world.

The first step in becoming carbon neutral is to calculate your carbon footprint which is the amount of greenhouse gases that you, or your organisation, produces in daily life.
The next step is to reduce your emissions which for people may involve changing some consumption habits and lifestyle choices, and for companies establishing a robust emission reduction program.
The final step is to compensate for the emissions you cannot entirely eliminate with carbon offset certificates which finance certified projects that remove carbon from the atmosphere in other parts of the world.

A comprehensive method for assembly and design optimization of single-layer pouch cells
For academic researchers, the cell format for testing lithium-ion batteries is often overlooked. However, choices in cell format and their design can affect cell performance more than one may expect. Coin cells that utilize either a lithium metal or greatly oversized graphite negative electrode are common but can provide unrealistic testing results when compared to commercial pouch-type cells. Instead, single-layer pouch cells provide a more similar…
Science is not value free
An interesting commentary addressing a rather odd prior commentary makes some very correct points.

Can Carbon Offsets Save Us? Fighting Climate Change with Carbon Offsets
In the past few years, the topic of climate change has worked its way into every area of our lives, and rightfully so. As we push closer to the irreversible effects of climate change and the ever-looming 2°C, companies, governments, and individuals are looking for every possible way to mitigate emissions. Carbon offsetting was first conceptualized in 1989, but has been gaining traction in recent years….

Climate change is one of the most pressing issues facing our planet today. It refers to significant changes in global temperatures and weather patterns over time. While climate change is a natural phenomenon, scientific evidence shows that human activities are currently driving an unprecedented rate of change. The primary cause of recent climate change is the increase in greenhouse gases in the atmosphere due to human activities. Key contributors include:
- Burning of Fossil Fuels: Coal, oil, and natural gas combustion for energy and transportation releases large quantities of carbon dioxide (CO2) and other greenhouse gases.
- Deforestation: Trees absorb CO2, and cutting them down reduces the Earth’s capacity to sequester carbon.
- Agricultural Practices: Methane emissions from livestock and rice paddies, along with nitrous oxide from fertilizers, contribute to the greenhouse effect.
- Industrial Processes: Certain industrial activities release various greenhouse gases, including CO2, methane, and fluorinated gases.
Effects of Climate Change
The impacts of climate change are widespread and varied, affecting ecosystems, weather patterns, sea levels, and human societies. Key effects include:
- Rising Temperatures: Global temperatures have been steadily increasing, leading to more frequent and severe heatwaves.
- Melting Ice and Rising Sea Levels: Polar ice caps and glaciers are melting, contributing to rising sea levels, which threaten coastal communities.
- Extreme Weather Events: Increased frequency and intensity of hurricanes, droughts, floods, and other extreme weather events.
- Biodiversity Loss: Many species are struggling to adapt to changing conditions, leading to shifts in ecosystems and potential extinctions.
- Human Health Risks: Increased heat can lead to heat-related illnesses, while changing weather patterns can affect food and water supply, leading to malnutrition and waterborne diseases.
Mitigation and Adaptation Strategies
Addressing climate change requires both mitigation and adaptation strategies. Efforts to reduce or prevent the emission of greenhouse gases include:
- Transitioning to renewable energy sources like solar, wind, and hydroelectric power.
- Enhancing energy efficiency in buildings, transportation, and industries.
- Promoting reforestation and sustainable land use practices.
- Developing resilient infrastructure to withstand extreme weather.
- Implementing water management practices to cope with variable water supplies.
- Protecting and restoring natural ecosystems to enhance their resilience.
Climate change is a complex and multifaceted issue that requires global cooperation and immediate action.
By understanding its causes, effects, and the strategies available to address it, we can work towards a sustainable future for our planet.
It is imperative for governments, businesses, and individuals to take proactive steps to mitigate climate change and adapt to its inevitable impacts.
