Environmental Highlights

In 2013, we became the first U.S. public company exclusively focused on financing solutions to climate change.
As such, we are committed to environmental sustainability both through our investments as well as in our own business operations.

  • We define sustainability as positively impacting the environmental while being neutral or negative on GHG emissions.
  • We evaluate the carbon impact of all projects using a CarbonCount score. We also evaluate the projects for other environmental benefits such as water use reduction.
  • Our corporate electricity is obtained from carbon free sources.
  • We are the first U.S. public company to commit to the Climate Disclosure Standards Board initiative to implement the recommendations of the Task Force on Climate Related Financial Disclosure (TCFD).

Embracing Environmental Accountability & Transparency

We quantify, rank and disclose the impact of all investments in our annual Sustainability Report Card. Below are the 2018 results for GHG emissions offset per $1,000 invested.

ESG Reporting / Sustainability Report card chart

Estimated carbon savings are calculated using the estimated kilowatt hours (“kWh”), gallons of fuel oil, million British thermal units (“MMBtus”) of natural gas and gallons of water saved as appropriate, for each project. The energy savings are converted into an estimate of metric tons of CO2 equivalent emissions based upon the project’s location and the corresponding emissions factor data from the U.S. Government and International Energy Agency. Portfolios of projects are represented on an aggregate basis.

CarbonCount® is a third-party scoring tool offered by The Alliance to Save Energy that evaluates investments in U.S.-based, energy efficiency and renewable energy projects to determine how effectively they can be expected to reduce CO2 emissions per $1,000 of investment.

*Investments in seismic retrofits provide resiliency in the event of an earthquake. A secondary benefit of such retrofits includes the preservation of carbon embedded in the built environment.

Supporting Leading Climate Action & Sustainability Initiatives

We actively partner with a number of campaigns and coalitions that reflect our commitment to the climate action, corporate sustainability progress, and clean energy expansion necessary to advance the goal of the Paris Agreement.
That is, limiting global temperature rises to no more than 2 degrees, and ideally 1.5 degrees.
