Under pressure from customers and investorsmany US corporations have committed to voluntarily reducing their impact on the climate. But this does not at all times mean they reduce their very own greenhouse gas emissions.
AND a large variety of corporations as a substitute, they pay others to reduce greenhouse gas emissions on their behalf through the projects they generate carbon offsets.
There are reasons to be skeptical of this practice. Chief amongst them is that projects designed to offset carbon emissions have long occupied land in poorer countries, displacing small farmers AND life-threatening in the method. The quality of some voluntary offsets traded all over the world has also proven difficult to confirm. This is recommended, for instance, by studies of forest relocation projects lots of them are usually not that effective in carbon sequestration, they claim.
We consider there’s a higher solution: Companies could spend a few of their carbon offsetting money on climate-friendly projects that not only reduce emissions, but additionally improve the lives of individuals within the U.S. communities where these corporations operate.
Our team On the Climate, Health and Energy Equity Lab at Vanderbilt University, he explored the potential of corporations contributing offset dollars to improve energy efficiency in low-income housing, starting with a pilot study in our hometown of Nashville. Efficiency improvements can save energy and money and reduce carbon emissions. At the identical time, they reduce among the many health risks created or increased by living in a home that’s difficult to properly heat and funky.
Such modernizations can be financed by sale of carbon offsets on “social coal segment. voluntary market for emission allowances. The combined economic, health and climate benefits of modernizing low-income energy sources could support such projects attractive for corporations wishing to meet their climate commitments and gain positive attention from the area people.
Energy efficiency pays off in some ways
In the US, low-income households spend on average 6% to 10% of your income on energy costs. Often, renters and homeowners struggle to maintain healthy temperatures in aging, poorly insulated homes.
For some people, the associated fee of heating their home can be so high that it becomes difficult alternative: “heat or eat”.”what can participate in a physical examination AND mental health toll.
In Nashville, we checked out implementing 4 key varieties of energy efficiency improvements in low-income housing. Together they can reduce energy consumption and energy-related carbon emissions while earning offset credits within the voluntary carbon market.
We calculated that a combination of replacing the windows, refrigerator, and heating and cooling system, and insulating the attic of a two-bedroom rental apartment in Nashville could reduce the carbon dioxide emissions from energy use in the house by an estimated amount 592 tons over 25 years of modernization operation.
If carbon emissions reductions from a Nashville home retrofit were packaged as carbon offsets and sold on a voluntary carbon market at a price of $30 to $45 per ton, the cash earned could cover the numerous material costs of energy efficiency retrofits. These prices are in step with the costs requested by other significant carbon offsets AND significant social advantages. It can also be quite possible that community health advantages would be more attractive to some corporate buyers than greenhouse gas reductions alone. Offset transactions may be facilitated by non-profit organizations, social enterprises or local governments.
Many of those improvements are too expensive for low-income households without outside financial assistance. Landlords tend to avoid them because tenants, not owners, pay utility bills.
Lessons from Maine and the Southeast
Projects are already mobilizing funds to offset carbon emissions for renewable energy and energy efficiency within the US
One of the early innovators was the Maine Housing Authority. Agency pilot financing for energy efficiency modernization of residential buildings with the sale of carbon offsetting allowances within the early 2000s and discovered how complicated this process can be.
Chevrolet’s purchase of $750,000 in carbon credits for a project in Maine in 2012 enabled it to increase efficiency to approximately 170 houses. The project revealed several essential findings, including the necessity for: a large variety of houses and a high carbon price for the project to repay. A 2012 review of this system found that while each home could generate a whole bunch of dollars in carbon credits, preparing the project, measuring and verifying the worth, and selling any such offset it can cost tens of hundreds of dollars before work on the homes begins.
To reduce these costs, our team member Maya Maciel-Seidman developed a way to quantify carbon reductions from upgrading home energy systems. It was able to reduce time and costs by counting on publicly available utility and government data combined with easy-to-perform ground measurements.

Another challenge of any such carbon offsetting – and offsets supporting clean energy production – you could come across issue of additionality: Would modernizing low-income energy systems still occur without carbon offset financing?
I do not think so. There are federal programs that provide funding to improve energy efficiency in low-income housing. However, over 40 years of federal weather assistance program experience and Energy assistance program for low-income households suggests that these programs don’t reach the overwhelming majority of eligible low-income households.
A solar startup within the southeastern United States provides one other example of carbon offsetting environmental AND additional economic advantages close to home. Clear loop generates carbon offsets by constructing utility-scale solar farms in the dirtiest parts of the US power gridregions with little renewable energy and highly polluting power plants. The company funds investments in photovoltaic energy through: selling carbon offsets prematurely representing the emissions saved over the lifetime of every solar farm.
Companies and residents profit
The use of carbon offsets isn’t a substitute for emissions reductions or for public policies and financing to eliminate fuel poverty and insecurity. However, we consider that mobilizing a voluntary carbon market to finance energy efficiency improvements in low-income homes could provide clear relief for a lot of households.
The physical proximity of corporations supporting such projects also needs to enable greater transparency and accountability. When corporations purchase carbon offsets which might be generated locally and supply additional advantages to host communities, they strengthen their social permit to operate while making progress on climate commitments.
