What Are Biofuels and How Can They Be Used?

By |2022-10-06T12:32:19+00:00October 6, 2022|Greenhouse Gases, Renewables|Comments Off on What Are Biofuels and How Can They Be Used?

Biofuels are fuels produced from organic materials or biomass. They are often promoted as a lower-carbon alternative to fossil fuels. Most biofuels today are used for transportation, as they can replace fuel in cars, trucks, aviation and shipping. Using biofuel in the automotive industry is nothing new. Many early vehicles in the United States were powered by corn-based ethanol. Rudolph Diesel even used peanut oil to test his first engine. Biofuels can be made from any biological material, though plant materials and animal waste are most commonly [...]

What Steps Can We Take to Achieve Carbon Reduction in Our Atmosphere?

By |2022-09-19T09:18:50+00:00July 14, 2022|Greenhouse Gases|Comments Off on What Steps Can We Take to Achieve Carbon Reduction in Our Atmosphere?

There are two ways to achieve carbon reduction in the atmosphere. The first is to reduce carbon dioxide (CO2) emissions. The second is to improve methods to remove CO2 already in the atmosphere.  Both methods are fundamental to combatting climate change. Humans have caused about 1.2°C of global warming since the Industrial Revolution. Releasing greenhouse gases, such as CO2 and methane (CH4), into the atmosphere is the driving force behind climate change. Therefore, we must stop adding more emissions and [...]

Natural Gas Energy: Is It a Clean Energy Source?

By |2022-09-01T14:24:45+00:00July 7, 2022|Climate Change, Greenhouse Gases, Natural Gas|Comments Off on Natural Gas Energy: Is It a Clean Energy Source?

In May 2021, the preceding Australian prime minister, Scott Morrison, announced that his government would spend up to AUD $600 million on a new gas-fired power plant in Hunter Valley, New South Wales. This is despite that the Australian energy board chair says that this "doesn’t stack up". This is just one of many new gas projects under development in Australia that are coming under fire for being environmentally and economically damaging. Despite promises to take more action on climate, [...]

Why Is Methane Gas Worse for the Environment Than Other Gases? (Video)

By |2022-09-12T15:41:15+00:00April 26, 2022|Greenhouse Gases|Comments Off on Why Is Methane Gas Worse for the Environment Than Other Gases? (Video)

While conversations often focus on carbon dioxide, this video shows how harmful methane can be to our environment. Which greenhouse gas is worse, carbon dioxide or methane? Most conversations about climate change focus on the harm that carbon dioxide (CO2) causes. However, methane gas is actually responsible for almost one-quarter of global warming from greenhouse gases. Even worse, total methane emissions have increased by nine per cent between 2000 to 2006 and 2017. This rise comes from the fossil fuel [...]

How Common Are LNG Exports in Australia?

By |2022-09-12T11:47:34+00:00April 26, 2022|Greenhouse Gases, Natural Gas, Natural Gas Prices|Comments Off on How Common Are LNG Exports in Australia?

Liquefied natural gas (LNG) is natural gas chilled to around -161°C to make it a liquid. In 2021, Australia was the world’s biggest exporter of LNG after shipments hit a record high. The fossil fuel industry portrays natural gas and its products as a “cleaner” energy source. They say it produces “less carbon emissions and fewer pollutants than other naturally occurring fossil fuels”. But, this is not true. Despite LNG being touted as cleaner than coal, once we consider the [...]

What Is a Carbon Footprint?

By |2022-07-25T11:45:39+00:00March 23, 2022|Climate Change, Global Warming, Greenhouse Gases|Comments Off on What Is a Carbon Footprint?

Our carbon footprint is an important metric to slow down climate change. It indicates the total amount of greenhouse gases (GHG) that human activities produce directly and indirectly. A carbon footprint is generally measured in equivalent tonnes of CO2 (CO2e). It can be associated with an individual, an organisation, a country, a product, an event, in addition to others. The world’s current carbon footprint is approximately 50 billion tonnes of CO2e each year. This is 40 per cent higher than [...]

What Are the Causes of Global Warming and How Can We Limit It?

By |2022-07-25T11:35:52+00:00January 5, 2022|Global Warming, Greenhouse Gases|Comments Off on What Are the Causes of Global Warming and How Can We Limit It?

The levels of carbon dioxide in the Earth’s atmosphere are at their highest in 800,000 years, according to scientists. This increased concentration of CO2 is causing global warming and our climate to become more erratic and extreme. The last time that CO2 levels were this high was more than three million years ago. Temperatures at this point were 2 to 3°C higher than they were before global warming started around 150 years ago. While this may not sound like much, [...]

What Is Carbon Capture and Storage (CCS)?

By |2022-07-25T11:34:48+00:00January 4, 2022|Fossil Fuels, Global Warming, Greenhouse Gases|Comments Off on What Is Carbon Capture and Storage (CCS)?

In July 2021, the oil giant Chevron celebrated a “significant milestone” in Australia. Its liquefied natural gas (LNG) facility in Gorgon, Western Australia, had captured and stored five million metric tonnes of carbon dioxide. This is equivalent to taking more than 1.6 million passenger vehicles off Australia’s roads for a year. The Gorgon complex was billed as a major ‘test case’ for carbon capture and storage (CCS) technology across the world, given that companies and governments say that CCS is [...]

How Does a Carbon Tax Work?

By |2022-07-25T11:22:31+00:00November 8, 2021|Global Warming, Greenhouse Gases|Comments Off on How Does a Carbon Tax Work?

A carbon tax is where a government sets a price that businesses have to pay, dependent on the amount of greenhouse gases that they emit. It is a financial incentive for corporations and consumers alike to reduce their emissions to avoid paying the carbon tax.  Australia introduced a carbon tax in 2011. However, it was repealed in 2014. Today, about 40 countries and 20 cities, states and provinces worldwide use carbon pricing mechanisms. Plenty of others are planning their implementation. [...]

What Are Fugitive Emissions and Why Are They So Dangerous?

By |2022-07-25T11:17:03+00:00November 8, 2021|Greenhouse Gases, Natural Gas|Comments Off on What Are Fugitive Emissions and Why Are They So Dangerous?

What are fugitive gas emissions? Fugitive emissions are leaks, losses or other releases of methane into the atmosphere by the fossil fuel industry. These leaks occur from the production, gathering, processing, transmission and storage segments of the natural gas supply chain. They are a serious issue. Methane is one of the most common greenhouse gases, responsible for driving 23 per cent of all global warming. How does a fugitive emission occur? Fugitive emissions are usually unintentional losses. They are often the [...]
