Carbon offsets that would not have occurred if the offset project had not been implemented. (This is one of four factors to consider when acquiring carbon offsets.)

Planting of new woods on places that had previously been devoid of trees.

Caused by humans. The current scientific consensus states that global warming is a direct result of the sharp rise in anthropogenic emissions of greenhouse gases.

A biomass-derived fuel, usually in liquid form. Bioethanol from sugarcane or maize, biodiesel from canola, soybeans etc.

Organic material from living or recently dead plants or animals.

Blue carbon is the carbon absorbed and deposited in biomass and sediments by living organisms in coastal (e.g., mangroves, salt marshes, seagrasses) and marine environments.

The California Cap and Trade Program is administered by the Western Climate Initiative (WCI) and controlled by the California Air Resources Board. This program began in 2012 with California and subsequently was linked to similar emissions programs from the Canadian provinces of Quebec, and briefly, Ontario as well. Both jurisdictions' allowances can be used for compliance. The cap and trade scheme includes major electric power plants, large industrial plants, and gasoline distributors, among other sectors. Visit the California Air Resources Board's summary of their cap-and-trade programhere.

A regulatory procedure that puts a "cap" on the amount of greenhouse gas emissions that companies are permitted to emit. Firms that come in under their limitations have the option to "trade" (sell) their excess emission permits to other companies that have exceeded their limit.

Permissions (credits) to release greenhouse gases for participants in a controlled carbon market.

Middlemen who do not hold offsets but enable transactions between project developers and end-users, merchants, and/or retailers.

The maximum amount of CO2 that the world can release while still having a good probability of keeping warming below the 2°C goal laid out in the Paris Agreement.

A process that separates (captures) a reasonably pure stream of carbon dioxide (CO2) from industrial and energy-related sources, conditions it, compresses it, and transports it to a storage site for long-term isolation from the atmosphere (sequestration). Carbon capture and storage is another term for it.

A method of capturing CO2 and then using it to create a new product. Carbon capture, utilization, and storage occurs when CO2 is stored in a product for a climate-relevant time horizon. Only when coupled with CO2 that has recently been removed from the atmosphere does CCUS lead to carbon dioxide removal.

Equal to the offsetting of one tonne of carbon dioxide or carbon dioxide equivalent. A monetary value is ascribed to the reduction or offset of greenhouse gas emissions; this is a general term for any tradable certificate or permit reflecting emissions reductions.

For as far back as geological evidence shows – at least 650,000 years – the Earth's natural carbon cycle has maintained a steady equilibrium of carbon dioxide in the atmosphere - around 275 parts per million (ppm). We discovered this by examining the contents of Antarctic ice cores. As a result of the natural carbon cycle: People and animals (source) use respiration to turn oxygen into carbon dioxide. Plants (sinks) absorb CO2 and release it back into the atmosphere. Over the seas, oceans both produce (source) and absorb (sink) carbon dioxide. Dead organic matter traps carbon underground in various forms such as fossil fuels (sink), while volcanic eruptions (source) can release CO2 from carbonate rocks deep inside the Earth.

A heat-trapping gas composed of one part carbon and two parts oxygen. Too much CO2 in our atmosphere causes the Earth to retain too much of the sun's heat, leading to global warming. And excessive global warming eventually leads to various complications that are detrimental to our planet and its inhabitants, such as rising sea levels or certain areas becoming too hot for humans to live in.

The quantity of carbon dioxide emitted into the atmosphere as a result of any given entity’s actions. Individuals, corporations, and even nations can have a carbon footprint.

A marketplace that treats emissions reductions as a commodity, where participating members can buy and sell carbon credits

Often known as having a net zero carbon footprint, this is achieved by either reducing carbon emissions to zero, or by balancing a measurable quantity of carbon emitted with an equivalent amount offset..

Also known as VERs (voluntary emission reductions), CRTs (carbon reduction tonnes), and ERTs (emission reduction tons/tonnes), carbon offsets represent a given amount of carbon sequestered, consumed, or otherwise removed from the atmosphere. Through a voluntary carbon market, they provide a chance for anybody to fund initiatives that decrease, avoid, eliminate, or sequester carbon dioxide.

A carbon sink is any natural or man-made reservoir that collects and stores any carbon-containing chemical component for an indefinite length of time, lowering CO2 concentrations in the atmosphere. The most important carbon sink on a global scale is the ocean.

Any source of carbon dioxide or equivalent greenhouse gases. People and animals, as well as seas and volcanic eruptions, are all natural carbon sources. Carbon emissions from human-caused sources include the use of fossil fuels, automobile exhaust, deforestation, and manufacturing, building, and mining activities.

A futures contract for allowances issued by the California Cap and Trade Program. Expired contracts result in physical delivery of CCA allowances to the Compliance Instrument Tracking System Service (CITSS) registry.

A futures contract for California Air Resources Board offset credits that may be used to meet certain compliance responsibilities under the California Cap and Trade Program. As a tangible product, contracts held to expiry result in actual delivery of California carbon offsets beyond the danger of invalidation in the CITSS register.

A process that separates (captures) a reasonably pure stream of carbon dioxide (CO2) from industrial and energy-related sources, conditions it, compresses it, and transports it to a storage site for long-term isolation from the atmosphere. Carbon capture and storage is another term for it.

A method of capturing CO2 and then using it to create a new product. Carbon dioxide collection, use, and storage occurs when CO2 is stored in a product for a climate-relevant time horizon (CCUS). Only when coupled with CO2 that has recently been removed from the atmosphere does CCUS lead to carbon dioxide removal

As defined by the UN Framework Convention on Climate Change, climate change is: “a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods”. In other words, in most contexts, climate change refers specifically to anthropogenic climate change, and not the Earth’s natural climate cycles. This includes both global warming as well as extreme weather events.

Compliance carbon markets, also known as mandatory markets, are governed by national, regional, or provincial law and compel emission sources to meet legally mandated GHG emissions reduction targets. Because compliance program offset credits are generated and traded for regulatory compliance they typically act like, and are priced like, other commodities.

The annual Conference of the Parties, also known as the United Nations Climate Change Conference. It's the decision-making body of the United Nations Framework Convention on Climate Change (UNFCCC) and includes over 190 countries.

A process in which CO2 is extracted directly from the atmosphere. This CO2 can be permanently retained in deep geological formations (resulting in negative emissions), or it can be used in food processing, for example, or mixed with hydrogen to make synthetic fuels. DAC

The reduction or removal of one metric tonne of carbon dioxide equivalent from the atmosphere (CO2).

With about 45% of EU greenhouse gas emissions covered by the EU ETS, it’s the world's largest cap and trade scheme. Emissions from heavy industry, electricity generation, and aircraft in the EU are covered by this programme, which was implemented in 2005.

Unexpected weather events and patterns that are considered extremely unusual outliers in the regions where they occur. Unexpected heat waves, such as the 2021 Western North America heat wave that set new record-high temperatures in Canada, or the February 2021 North American cold wave that caused significant damage in the state of Texas, are examples of such events. There is some evidence to suggest that climate change is causing extreme weather events to occur both more frequently as well as more severely.

Fuels derived from hydrocarbon deposits formed by fossils, such as coal, oil, and natural gas. The combustion of these products, for example in car engines or coal-fired power plants, produces greenhouse gases like carbon dioxide.

An increase in the world’s average surface temperature, as compared to a baseline reference period. The average temperature of world has increased by approximately 1°C since the late 19thcentury, and the scientific consensus is that human activity is the primary contributor.

A scientific measure that compares how harmful each greenhouse gas is to the atmosphere, in terms of how long they stay there and how much heat they trap, relative to carbon dioxide. See also: Carbon Dioxide Equivalent.

A non-governmental emission reductions project certification scheme. It participates in the Clean Development Mechanism (CDM), the Voluntary Carbon Market, and many climate and development initiatives.

Gases that trap heat in the atmosphere. Carbon dioxide, methane, nitrous oxide, and fluorinated gases are the primary greenhouse gases. See also: Carbon Dioxide Equivalent.

The use of false or misleading promotion and marketing to exaggerate an organization's environmental or sustainable activities.

Defined in the Kyoto Protocol, an ICE Certified Emission Reduction futures contract is a futures contract for a carbon offset unit that may be used to meet EU ETS compliance obligations.

A futures contract for permits issued by the European Union Emissions Trading System. Contracts held to expiry result in physical delivery of EUA allowances within the Union Registry.

An index based on prices from the EU Emissions Trading Scheme (EU ETS), the California Cap and Trade Program, and the Regional Greenhouse Gas Initiative (RGGI). The secondary futures market for such programs, which trade on ICE's futures exchanges, accounts for the majority of volume in all carbon-based futures contracts. Visit the ICE Carbon Futures Index Family here.

The ICE Regional Greenhouse Gas Initiative futures contract is a contract for RGGI allowances. The RGGI is a collaborative program comprised of 11 northeastern U.S. states, and RGGI allowances are physically handed to the RGGI-COATS registry when contracts are held to expiry.

A global accord signed in 1997 that aimed to decrease greenhouse gas emissions. The phrase "carbon credit" appeared for the first time in the Kyoto Protocol. The Kyoto Protocol would later be superseded by the Paris Agreement.

Changes in how a particular area of land is used or managed. For instance, land use change is one of the primary reasons why the Amazon rainforest has gone from being one of the world’s largest natural carbon sinks to becoming a carbon source instead.

When a reduction in emissions from a carbon offset project in one location produces a rise in emissions in another area. For example, when preserving a forest in one region transfers logging activities to another area of forest.

Mandatory (compliance) markets are governed by national, regional, or provincial law and compel emission sources to meet GHG emission reduction targets. Because compliance program offset credits are generated and traded for regulatory compliance, they typically act like other commodity pricing.

A power measurement unit equal to one million watts. One megawatt is approximately equal to the amount of energy produced by ten car engines.

Equivalent to 1,000 kilowatts of continuous power consumption for one hour. It’s about comparable to the amount of power consumed by 330 households in a single hour.

A condition in which greenhouse gases emitted into the atmosphere are balanced by the amount of greenhouse gases being removed from the atmosphere. See also: Carbon Neutral.

A condition in which greenhouse gases entering the atmosphere are balanced by removal from the atmosphere.

Paper licences provided in exchange for the purchase of carbon credits. Offset certificates should include a serial number unique to the offset, total tonnage bought, the verifier's name and signature, project location, owner's name and address, and a vintage date.

An international treaty on climate change that superseded the Kyoto Protocol. Signed in 2016, the agreement has been ratified by all but six countries in the world. The long-term goal of the Paris Agreement is to keep global warming below 2°C, and the treaty contains various provisions to enforce this target.

A model scenario for climate change based on current scientific understanding. The 1.5°C pathway, as laid out by the Intergovernmental Panel for Climate Change, forecasts a 50-66% chance that global warming will remain at or below 1.5°C by the year 2100 after a brief overshoot. This pathway would require the entire world to cut greenhouse gas emissions by 7.6% each year, halving emissions by 2030 and reaching net zero status by 2050.

Rather than limiting projects to those that wouldn’t be viable without the carbon market, the performance standard counts as offsets any energy reduction that’s less than a specified threshold. In some cases, a project may be good for the environment, but would have happened regardless, independent of assistance from the carbon market. As a result, projects with the performance standard generally aren’t as “high quality” as more rigorously certified carbon reduction projects.

Offsets that are long-lasting or guaranteed to be replaced in the event of a loss. This is one of four factors to consider when acquiring carbon offsets.

Carbon offsets that have already actually reduced carbon emissions, as opposed to those that are expected to do so in the future. This is one of four factors to consider when acquiring carbon offsets.

Projects in areas where forests are in danger due to land-use change, resulting in reduced carbon storage. REDD+ projects aim to save these forests before they’re degraded or deforested, avoiding a worse-case scenario that leads to increased emissions.

A multi-state cap and trade scheme first established in 2009. This program encompasses the 11 U.S. states of Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, Vermont, and Virginia. Each participating state has its own limitation on fossil-fuel-fired electric power plant emissions. Each state's allowances, like California's, can be utilized interchangeably for compliance.

Where members are legally obligated to reduce their emissions.

A Kyoto Protocol unit equal to one metric tonne of carbon dioxide equivalent emissions absorbed or removed by a carbon sink project. RMUs are granted for carbon dioxide removal from the atmosphere by qualifying land use, land use change, and forestry activities.

Energy derived from sources that can be naturally renewed in a relatively short amount of time. The five most common renewable sources are biomass (such as wood and biogas), hydropower, geothermal (heat from inside the earth), wind, and solar.

Unlike a carbon offset, which represents one tonne of CO2e emissions reduction, a renewable energy credit represents one MWh of energy produced by a renewable energy source, such as solar, wind, or hydroelectric power.

To permanently remove carbon offsets from the market in order to prevent them from being resold after they’ve been used up. Offsets are typically decommissioned by assigning them unique serial numbers and registering them in an official registry.

The release of greenhouse gases into the atmosphere from sources such as buildings and operations directly owned or controlled by an organization. For example, if a company owns a fleet of trucks, the greenhouse gases emitted by these trucks would count towards the company’s Scope 1 emissions.

The discharge of greenhouse gases as a result of the electricity, heating, cooling, or steam generation required to power an organization’s buildings and other facilities. For example, if a company’s headquarters building draws power from a coal-fired power plant, a proportional amount of the emissions resulting from that coal plant’s electricity generation would count towards the company’s Scope 2 emissions.

The release of greenhouse gases into the atmosphere generated as a result of an organization’s activities, but physically produced by another entity. For example, if you drive a fossil-fuel-powered car, the emissions it produces would count towards the car manufacturer’s Scope 3 emissions.

The removal of carbon dioxide from the atmosphere through biological (for example, photosynthesis in plants and trees), chemical (for example, turning CO2 into carbonate minerals), or physical processes (for example, storage of carbon dioxide in underground reservoirs).

The United Nations established 17 global development goals for all countries through a participatory process, elaborated in the 2030 Agenda for Sustainable Development. These goals include ending poverty and hunger, ensuring health and well-being, education, gender equality, clean water and energy, and decent work; and building and ensuring resilient and sustainable infrastructure, cities, and communities.

Adopted in 1992 and made available for signing during the Rio de Janeiro Earth Summit in 1992. It went into effect in March 1994 and had 197 signatories as of last year. (196 States and the European Union). The ultimate goal of the Convention is to ‘stabilise greenhouse gas concentrations in the atmosphere at a level that would preclude hazardous anthropogenic influence with the climate system.' Two accords pursue and implement the Convention's provisions: first the Kyoto Protocol, and now the Paris Agreement.

Carbon offsets that can be quantified, tracked, and validated are known as verifiable offsets. (This is one of four factors to consider when acquiring carbon offsets.)

An authorised third-party auditor conducts an impartial review of the carbon offset project design and baseline calculations prior to the start of project activity.

A unit equating to one metric tonne of certified, reduced, and issued carbon dioxide equivalent emissions under the Verified Carbon Standard.

Carbon credit generated by a project that has been independently validated outside of the Kyoto Protocol. One VER equals one tonne of CO2e emission savings.

This is a certification standard for non-governmental emission reduction initiatives, similar to the Gold Standard. It participates in the Clean Development Mechanism (CDM), the Voluntary Carbon Market, and many climate and development initiatives.

The year of emissions reduction that a carbon credit belongs to. The vintage of an offset may not necessarily match the year of the transaction, and the vintage year may even be in the future.

A carbon market in which members are not legally compelled to reduce their emissions but do so voluntarily. These markets enable carbon emitters to offset their emissions by acquiring carbon credits generated by third-party initiatives aimed at removing or decreasing GHG emissions from the environment. Companies can engage in the voluntary carbon market on their own or as part of an industry-wide program.

It’s the impact created on the climate as we go about our daily lives and comes from the greenhouse gases emitted from each decision we make throughout the day – either directly or indirectly. It’s a way of representing your personal contribution to the polluting gases that cause climate change. These gases are often referred to as ‘greenhouse gases’ due to their effect on the planet’s climate.

From the type of car you drive to the construction materials of your new wardrobe – it all leaves a footprint. You can find out more in our article explaining exactly what a carbon footprint is.

The biggest stakeholders are society as a whole.

Climate preservation is a big, urgent task that will likely take trillions of dollars invested in reversing climate change before we are on track and balanced..

As GeorgeKenny finds a sustainable business model to champion, we find it will be much easier to raise the funding necessary to complete the large infrastructure projects that are necessary to balance out climate change by inspiring you with art and fashion.

Carbon neutrality is when you have a net-zero carbon footprint, which can only be achieved by carbon offsetting. Through offsetting, individuals and organisations can become carbon neutral by taking action to remove as much carbon dioxide equivalent from the atmosphere that they put into it.

‍Offsetting is a way to compensate for your carbon emissions by funding an equivalent carbon dioxide saving elsewhere. Offsetting projects could be native restoration or renewable energy projects, for example, and can be either domestic or international.

Fund 4 types of climate solutions.

1. Technology

Carbon removal technologies like biochar and mineral weathering turn atmospheric CO2 into solid rock—locking up carbon for thousands of years.

2. Tree Planting

Trees are nature’s soldiers in the fight against climate change, and Wren members help plant millions of native species every year.

3. Policy

Wren members support leading policy groups that push for changes to our economies, agriculture, infrastructure, power grid—every system that influences our planet’s climate.

4. Conservation

Natural ecosystems like old growth forest, peat bogs, and mangrove swamps are the lungs of the earth. Wren members help protect them.

The model is grounded in research from UC Berkeley's CoolClimate Network and data from the World Bank to estimate your carbon footprint, based on the lifestyle factors you enter.

Here's how it works:

1. pull in typical baseline carbon footprint values from Berkeley's Cool Climate project.
2. We calculate your country's average carbon footprint using data from World Bank, then scale the baseline carbon footprint values by your country's average.
3. As you input your own details into your carbon footprint, we run that information through Berkeley's Cool Climate model.

Climate change is hard to get your head around– and we've found that contextualising it in terms of an individual's lifestyle helps people understand how they can make a difference.

1 kg of CO2e is equivalent to a (large) beach ball with a diameter of slightly over 1m (3 feet).

‍This is the same amount of CO2e produced by driving an average car 3.56 miles. It's the same as half a litre of petrol, or 128 smartphone charges.

Greenwashing is like the modern-day equivalent of cigarette companies claiming smoking is good for you. We eventually saw past the lies from tobacco companies and we need to decouple ourselves from dirty fossil fuels as soon as possible.

Although it is great for any company to fund climate solutions, fossil fuel companies and other big emitters should not be let off the hook just for buying carbon offsets. To end the climate crisis, every oil and gas company will either have to shut down or completely transform their business. Carbon offsets are not a viable longterm solution for these companies to keep polluting.

We spread the word. Collective action refers to the collaborative efforts of a group of people working together towards a common goal. At GeorgeKenny, we believe in the power of collective action. We have built our business off the belief that millions of small changes made by millions of individuals can have a significant impact and help us solve the climate crisis.

To end the climate crisis, we broadly need to do 4 things: produce way more clean energy (and stop burning fossil fuels), decarbonize all of our greenhouse gas emitting infrastructure (everything from cars and stoves to steel and cement factories), save our forests and other natural ecosystems that are currently storing gigatons of carbon, and transform our food system to stop emitting so much greenhouse gases. To avoid the worst effects of the climate crisis, we need to do all of this in the next 10 years. Since it's almost impossible to get these four giant tasks done in 10 years, we also need to get to work removing carbon from the atmosphere through planting and restoring more forests, practicing carbon-sequestering agriculture, and likely even building machines to suck carbon directly from the air.

That gives us a total of 5 big priorities: make tons of clean energy, decarbonize our infrastructure, protect our carbon sinks, transform our food system, and remove carbon from the atmosphere. At Wren we think we'll one day be helping with all of these, but at the moment are focused on protecting our existing carbon sinks like the Amazon Rainforest, and on removing more carbon from the atmosphere through tree planting, biochar production, and other solutions.

While effects of climate change are already being felt worldwide (historic wildfires, flooding, and heatwaves to name a few), there is still time to avoid many of the worst case scenarios and end the climate crisis for good.

However, every day we wait makes the peak of the climate crisis a bit worse. Based off the IPCC's best estimates, our "carbon budget" to mitigate the worst of global warming is blowing by fast, with only around 10 years before we pass a threshold of 1.5° of warming. It's never too late to address the climate crisis, but every day we delay means more extreme weather, more climate refugees, and more people dying—we must act immediately.

Climate change is hard to get your head around– and we've found that contextualising it in terms of an individual's lifestyle helps people understand how they can make a difference.

We use a model grounded in research from UC Berkeley's CoolClimate Network and data from the World Bank to estimate your carbon footprint, based on the lifestyle factors you enter.

Here's how it works:

1. We pull in typical baseline carbon footprint values from Berkeley's Cool Climate project.
2. We calculate your country's average carbon footprint using data from World Bank, then scale the baseline carbon footprint values by your country's average.
3. As you input your own details into your carbon footprint, we run that information through Berkeley's CoolClimate model.

Carbon dioxide makes up 75% of total GHG emissions. CO₂e represents the global warming potential of CO₂ plus the remaining 25% of emissions from methane, nitrous oxide, hydrofluorocarbons, and other potent GHGs converted to carbon dioxide equivalents (CO₂e). CO₂e is measured in metric units, so when we say a ton of CO₂, we mean 1 metric tonne (~2204.6lbs) of CO₂e.

Carbon offsets are the key funding mechanism for projects that are planting billions of trees, producing biochar, destroying refrigerants, protecting the Amazon rainforest, and much more.

Not all carbon offsets are created equal, though—historically, some projects funded by carbon offsets have failed to be transparent with their impact. Our focus at Wren is finding the most impactful, transparent projects for members to fund each month.

Everything you do in life– driving a car, flying a plane, even the food you eat and the things you buy, emits some amount of greenhouse gases into the atmosphere. All these things add up to your carbon footprint.

By funding climate solutions like tree planting, rainforest protection, and biochar, you can support the removal of greenhouse gases from the atmosphere– and offset your carbon footprint. This lets you effectively live carbon neutral.

We pick climate projects based on four primary criteria:

1. Measurable results
2. Lasting impact
3. Wouldn’t happen without your funding
4. No double counting

We have a whole page dedicated to this subject, and we recommend you read about our how we choose projects here.

When we choose to fund a project, we establish a direct relationship with the team behind the project, ensuring quality progress updates on a monthly cadence, plus access to financial and other key details about the project.

All of this is passed on to Wren members, and when a project under-delivers, we will keep you apprised and allocate funds toward other projects.

Why Trees matter

The trees we plant with Eden Reforestation Projects support wild life diversity, improve coastlines, provided meaningful wages to indigenous population and grow Mangrove trees which are an incredible carbon sink.

Impact of planting Mangrove trees

‍Mangroves are unique ecosystems found throughout a wide range in the tropics and occupying the intertidal areas of more than 120 countries. Mangroves, and coastal wetlands in general, are globally important for the many services they provide to humans and the planet. These services include protection against storm surges, sheltering nurseries for fish and other marine life, providing building materials, firewood, and providing critically important services to stabilizing the global climate as an important store of carbon.

Mangroves, an incredible carbon sink

‍With the rapid increase in greenhouse gas emissions over the last century, the need for enduring carbon sinks has grown. The latest models suggest that to remain within “acceptable” global temperature increase, it is no longer enough to simply reduce emissions, and protect existing forests, but rather that we need to rapidly increase the ability to sequester carbon. Globally, mangrove systems are estimated to hold an astounding 20 petagrams of carbon. For a biome representing less than 5% of the world’s terrestrial area, this makes mangroves one of the most important carbon stocks, even more than many rainforests like the Amazon. Equally, as a relatively fast-growing group of species, mangroves sequester carbon at a very fast rate.

Help support wildlife and diversity

‍As forests are destroyed, wildlife species lose their natural habitat, forcing them to relocate, limiting their ability to survive. Madagascar is one of the world’s greatest conservation priorities, with over 200 species of mammals, 100 species of lemurs, 300 species of birds, and almost 300 species of amphibians. Around ninety percent of all wildlife in Madagascar is endemic. Our work with Eden protects these wildlife species in Madagascar by restoring their natural habitats.

The Wren Climate Portfolio is a dynamic portfolio of the best solutions to climate change.

The projects reduce and remove CO₂ by planting trees, promoting sustainable agriculture, protecting rainforest, and more.

Wren members offset their carbon emissions each month by contributing to the Climate Fund.

You can learn more about the projects in the Fund here.

Yes. Occasionally, we'll onboard a new project (see: Biochar in California, our first U.S.-based climate project) to the Fund.

We regularly update the fund allocation to make sure our members are having the most impact they can. Often, this means sending more money to a particularly promising project. Occasionally, it means diverting funds from a project that isn't going according to plan.
