Sustainability Metrics Matter, Part 1 of 3
Sustainability is now in its second decade as a buzzword. Like many, I am still trying to understand exactly what it means. Surely, its definition varies depending on who you are, where you are, and what you do, as you add or take away from the mix of social, economic, and environmental ingredients of the sustainability recipe. With the framework and methodology we developed here at Sustainable Harvest, we prepared reports on our carbon footprint, our sustainability performance, and our suppliers’ sustainability.
To share our efforts to quantify our contribution to sustainable development, we’re writing a series of three blog posts to describe the scope of the process, the challenges, and the results as they unfold. This post discusses the trend of sustainability assessment as a tool to quantify qualitative descriptions of impact and enhance decision-making. The second post will focus on sustainability assessments conducted by independent, third-party organizations that evaluate our internal operations, most notably B Lab and Genuine Metrics. The last post of the series will address global sustainability initiatives and standards, and Sustainable Harvest’s pilot assessment of supplier sustainability. It will also address the challenges around that process and some of our initial findings on supplier well-being and needs.
Since emerging at the Earth Summit in Rio de Janeiro in 1992 and gaining speed in both the Global North and South by the early 2000s, the concept of sustainable development has become mainstream. The trend of sustainability assessment and metrics emerged in the early 2000s as policymakers, managers and investors, civil society leaders, and the public began to demand evidence to support “green” claims. In response, consulting firms and experts such as the International Association for Impact Assessment organized and developed measurement tools. These tools help to analyze efficiency, effectiveness, and impact; demonstrate the extent of progress to management and key stakeholders; inform learning and strategic decision-making; compare actual results with those expected; ensure accountability; and ultimately, establish a strong foundation to bring sustainability efforts to scale.
Last month, we released a carbon footprint report that quantifies our business’ total carbon emissions. We see climate change as an increasing threat to the coffee supply chain, and it directly affects the farmers Sustainable Harvest works with in developing countries. Our sustainability team’s analysis shows 2009 CO2 emissions from the shipment of coffee in our legal possession (via ocean freight and trucking), as well as from staff air travel and from energy usage at all of our global offices (US, Mexico, Peru, and Tanzania). Our calculations show that carbon emissions from these activities totaled 657 metric tons (t) during 2009. In the process of transporting green coffee some 240,700 miles, 577t CO2e were emitted. In terms of operations, staff air travel resulted in estimated emissions of 78t CO2 and all office energy consumption emitted a total of 7t CO2. While approximately of 85% of our direct emissions are a result of shipping green coffee, it is important to note that coffee shipments transported by sea from origin to the US market contribute a relatively small portion (only 3 percent) of coffee’s total carbon footprint, on average (Clay, in Kornell 2009).
The carbon footprint report also analyzes the carbon sequestration from the Kigoma tree planting project in Tanzania. This initiative plants native tree species on denuded coffee plantations and was designed to restore local biodiversity, provide shade for coffee plants, reduce runoff, and sequester carbon. From 2008-2010, the project has planted 131,800 trees that will sequester an average of 805t CO2 each year.4 We estimate that this project sequesters 20% more carbon than we emit through business activities. The Kigoma project is one example of the ways in which Sustainable Harvest and coffee roasters support sustainability projects to improve conditions in the communities and ecosystems where their coffee is sourced.
Measuring our carbon footprint report is the first step in sustainability assessment and metrics that reinforce our work and the impact of our trade model. Another significant step is third-party certification and analysis, like B Lab and Genuine Metrics, the topic of our next blog post.
