If you ever wondered what the weather might look like should global average temperatures rise 2°C degrees above pre-industrial levels – the critical warming threshold the Paris Agreement seeks to prevent us from reaching – think back to Friday November 17. That day, for the first time since records began, global surface air temperature briefly reached 2.07°C above pre-industrial levels. While this does not mean that we have breached the global climate agreement’s target, the frequency at which the mercury jumps over that line raises serious concern. In the wake of this year’s global annual climate talks, COP28, one could hope that this would shock governments into strengthening their climate goals. But this point in time ought to be a moment of reckoning for companies, too. The data, however, indicates otherwise, as executives lie about their environmental, social and governance (“ESG”) efforts and cut green spending further.
20 sustainability schemes under the microscope
Thankfully, there are many ways that companies can change course, starting at an internal level with sustainability schemes. For the stake of clarity, we define sustainability schemes as organized initiatives to provide sustainability guidance to companies through principles, frameworks, guidelines, and standards. My recent research with James Demastus assessed 20 of the most frequently used environmental sustainability schemes for their effectiveness in advancing sustainability, including the UN Sustainable Development Goals, the Global Reporting Initiative, and Certified B Corporations.
The United Nations’ Sustainable Development Goals (“SDG”) are among the most famous. By contrast to other schemes, SDGs are country-level initiatives that businesses can choose to contribute to or not. Companies are free to identify any of the 17 SDGs that are aligned with their goals, such as affordable and clean energy, climate action, or sustainable cities and communities, and carry out sustainable practices that will contribute to reaching the global SDG goal. Note that participating companies are not held to any SDG requirements or accountability frameworks, and instead, enjoy the warm glow of taking part in a global movement for sustainability.
Sustainability reporting guidelines are another type of scheme. In the European Union, annual sustainability reporting is required for all large companies. When a company writes a sustainability report to share its sustainability activities, such as its public commitment to help achieve the SDG, they often use a reporting template, such as the Global Reporting Initiative (“GRI”). The GRI template has been adopted by more than 10,000 companies worldwide and is the most widely used sustainability reporting framework. The GRI specifies what non-financial information that companies should disclose, such as energy usage, waste production, greenhouse gas emissions, impact on biodiversity, and environmental compliance. However, there are numerous other sustainability reporting templates, and it is not mandatory to follow the GRI format.
As an example, Unilever and Audi both use the GRI reporting guidelines. In its environmental sustainability disclosure, Unilever’s 2021 sustainability report states that it has achieved a 64 percent reduction in operational carbon emissions and is pursuing a target of zero operational carbon emissions by 2030.
Company sustainability certification standards are yet another type of scheme. Certified B Corporation (“B Corp”) guides companies to priorities workers, community, and the environment alongside profit. Fashion brand Chloé, resale company Vestiaire Collective, sneaker-maker Allbirds, the Body Shop and Tony’s Chocolonely are all Certified B Corps. And B Lab, the organization that oversees B Corp certification, reports that Tony’s Chocolonely, for example, does quite well in meeting the (not legally binding) B Corp standards for environmental management, air and climate impacts, and land and biodiversity impacts, but has room for improvement in the area of water impacts.
It should be added that there is significant overlap in environmental sustainability scheme topics and the above schemes are not exclusive, and it is not uncommon for companies to use half a dozen or more schemes at a time.
Weak, incremental benefits
Our research concluded that all 20 of the commonly used schemes in our study aligned with various forms of weak sustainability that promote incremental sustainability progress and continue to advocate for a growth-oriented economy. For example, most schemes only consider a company’s internal or operational carbon emissions and ignore the supply-chain emissions generated by a company’s choice of materials, suppliers, and transit options – which they can account for more than 90 percent of a company’s carbon emissions. Consider Unilever’s 2021 sustainability report, which shows the company’s internal operational emissions for the year were 710,740 tons of carbon dioxide equivalents. However, the company’s supply-chain emissions for the year amounted to 61,007,131 tons, or 98.8 percent of the company’s total (operational plus supply chain) emissions.
Furthermore, many schemes are vague and offer no guidance on how to reduce operational carbon emissions. Coming back to the three schemes cited at the top of the article, SDG requires countries to “take urgent action” to address climate change, the GRI requires companies to simply report greenhouse gas emissions, and B Corp certification demands that companies to “take action in accordance with science.” In practice, companies are left to navigate the options available and decide on the best course of action.
As a result, companies often take the easy route of buying carbon offsets, which have come under great scrutiny as being worthless or even downright polluting, instead of companies tackling the hard work of reducing internal operational emissions. Aware of such trends, the EU has recently passed legislation that requires companies making climate-related claims to disclose if they are slashing internal operational emissions or relying on carbon offsets.
On a positive note, our research identified five schemes that performed better than others, including frameworks centered on concepts such as the circular economy, doughnut economics or planetary boundaries, and The Natural Step framework, and the certification standard scheme ISO 14001. The circular economy seeks to minimize companies’ carbon footprint by reducing demand for new materials, slash waste and increase products’ durability overall. Among this school of thought’s notable followers is the EU with its Circular Economy Action Plan, which it expects will contribute 0.5 percent additional GDP growth and 700,000 new jobs by 2030.
Doughnut economics is a theoretical model that defines maximum ecological limits that we should not exceed and minimum basic social needs that we should meet; the goal is to stay between these two limits to maintain a flourishing and healthy planet and society. Amsterdam, Copenhagen, Brussels, and Berlin are among its early adopters. Meanwhile, the model is proving a harder sell for businesses, who are just beginning to explore how it could help them (re)design business for sustainability.
Planetary boundaries is a framework that identifies nine processes that regulate earth systems, such as climate change and ocean acidification, and researchers quantified those processes to determine the boundaries within which humans can comfortably live. Governments and businesses have taken interest in how to stay within those boundaries and, more importantly, how to prepare for future impacts from breached boundaries. Hitachi has publicly committed to keeping its corporate activities within planetary boundaries with a focus on “growth within the limits.” Yara also reports that it is working to respect planetary boundaries within its agricultural supply chain, especially through the increased efficiency of nutrients.
The Natural Step (“TNS”) framework was started over 30 years ago in Sweden and was the first to develop a shared definition, vision, principles, framework, and process for companies to begin the sustainability journey. Nike was an early adopter of The Natural Step through its Reuse-a-Shoe program to take back worn shoes for recycling; the program continues today. Scandic Hotels also began its sustainability work under the advisement of The Natural Step and continues to follow TNS principles: do not degrade the earth, over-extract from the Earth’s surface, produce too much waste, or interfere with individuals’ capacity to meet their own needs.
Best certification standard schemes
One established certification scheme also stood out: ISO 14001, an environmental management system certification for companies to measure and improve environmental impact. Companies select metrics relevant to their operations, such as paper usage, electricity usage, and the weight of waste sent to the landfill. Toyota Europe and steel manufacturer Swebor are both ISO 14001 certified, meaning that they have procedures in place to measure and manage environmental impacts of company operations. Swebor states certification leads to less waste, increased use of renewable resources, and increased efficiency.
The other schemes not mentioned in the study, such as the European Commission’s Eco-Management and Audit Scheme, the United Nations’ Global Compact, and the Carbon Disclosure Project, were more oriented toward sustaining business rather than sustaining our human habitat.
