As global warming worries approach critical mass, corporate bond investors expect issuers to be part of the solution. At the epicenter of the climate crisis are greenhouse gases (GHG), which all industries emit in one way or another. Most companies strive to shrink their emissions, or carbon footprint, but others take an additional step to avoid them altogether and improve their carbon handprint.
Carbon Handprint Measures Positive Climate Contribution
The planet has nine years to improve carbon emissions trajectories and avoid catastrophe, according to a study released at the recent UN COP27 climate conference. Global warming experts at COP27 said that reducing carbon output alone is now insufficient to hit long-term net zero* goals. More and novel approaches are critically needed, especially prevention.
To understand how carbon emissions prevention and avoidance works in industries, investors should look to carbon handprint. While carbon footprint measures GHGs produced from a company’s† activities across its operations and third parties, carbon handprint sums up emissions that never reach the atmosphere.
Carbon handprint considers new or improved facilities and processes that directly prevent, restrict or avoid additional carbon output, whether by the firm, its customers or anything else in its orbit. In contrast to carbon footprint, the bigger the handprint, the better the positive impact. Going forward, more companies will endeavor to shrink their footprint and grow their handprint.
Carbon handprint adds a new dimension to climate-aware fixed-income investing. It’s another yardstick of an issuer’s positive contribution to a better environment. It also strengthens the framework around standards that managers use to score certain ESG-labeled issues, especially green bonds. And with a more accurate picture of a green bond’s potential, managers can weigh the worth of its greenium, the negative yield between a company’s green and conventional issues.
Assets Everywhere Can Be Gauged Using Carbon Handprints
Although carbon handprint is still underappreciated, we find what it says about a firm’s GHG output useful across the fixed-income spectrum. Its key metrics can be harvested practically from any asset and are applicable to every industry. Handprints can stem from major construction of a new green-certified factory, the simple installation of energy-efficient lighting and so much in between. Based on our research with the Columbia Climate School, we believe solar and wind power, thermal insulation and electric vehicles (EVs) will have the most impact on GHG avoidance by 2030—in other words, the largest carbon handprints.
Carbon handprint is expressed in metric tons of CO2 prevented or avoided, so it reveals whether an issuer produces more carbon than it prevents. For example, each metric ton of CO2 that a thermal-insulation maker emits during production results in 200 metric tons of avoided carbon output for its customers, an impressive 200:1 handprint-to-footprint ratio (Display 1). Ratios can vary widely, especially across company types. So, a firm’s relatively small handprint-to-footprint ratio can still reflect a big contribution to carbon avoidance within its particular industry.
Handprints Can Be Evaluated Based on Economics
Our research also shows that the cost to reduce or avoid carbon emissions varies widely by product and industry. For example, in commercial jetliner production, carbon fiber (at $4 per metric ton of carbon reduction) is by far the cheapest material to implement (Display 2), primarily because it’s so widely used for its superior strength and energy-saving lighter weight. Meanwhile, biofuels and cold storage are significantly less economical paths to increase carbon handprints. However, with future innovations likely, we think their costs will drop over the next decade, along with the cost of EV adoption and the use of green construction materials.
The costs of carbon reduction have wide implications for fixed-income research, and not just in carbon-intensive sectors. Firms in all industries may want to improve their carbon handprints, but implementation costs matter. Companies tend to lean toward more cost-effective carbon handprint solutions such as LED lighting, thermal insulation and carbon fiber. We believe our cost research helps identify the businesses that stand to benefit from the demand.
Handprint Completes the Story When Comparing Bonds
As a comparative tool, carbon handprint can broaden a climate-aware bond investor’s perspective when screening for opportunities, especially among green bonds, which mandate a materially more detailed disclosure that helps investors compare carbon footprints and handprints more granularly. For instance, Brookfield Renewable Partners and Star Energy are two relatively similar issuers, both with highly credible green bond frameworks and environmentally friendly assets. They’re both renewable electricity providers and advocates for climate improvement. But a two-tier analysis shows that one has a greater carbon handprint.
Based on Brookfield’s green bond proceeds and annual output, its investment per unit of energy produced is slightly cheaper than Star Energy’s, and its emissions (carbon footprint) is a respectable 24% lower.
Diving a little deeper, however, Star Energy has the bigger handprint, including over 700,000 more metric tons of avoided CO2 output per year, which it reached at almost half the cost per ton compared with Brookfield. This nets it an impressive 110:1 handprint-to-footprint ratio (Display 3).
We’ve come far to bring nations together toward common climate goals, but the general takeaway from COP27 is that global warming remains an urgent threat. If economies are to prosper, companies will need to do their part.
We believe that spending on decarbonization technologies will need to exponentially grow in the next decade to hit corporate net zero targets on time. This massive spending will favor companies that provide decarbonization solutions that not only lower emissions internally, but also avoid them across the entire value chain, offering attractive investment opportunities for fixed-income investors.
