Climate Change Leaders: 350 Best U.S. Companies

Oct 9th, 2010 | By | Category: Climate Change

On 4 October 2010, Maplecroft launched rebalanced rankings for the Climate Innovation Indexes (CIIs), which rate the top 350 U.S. companies based on their climate innovation and carbon management programs. The CIIs identify climate change leaders that are positioning themselves to seize opportunities and deliver sustained growth in a carbon-constrained future business environment. A total of 350 companies were rated against 100 performance-based criteria. These criteria include

  • the capacity to generate innovative new technologies or initiatives that capitalize on climate-related market opportunities
  • the management of climate change through policies, disclosure, targets, verification and supply chain processes
  • the mitigation of carbon emissions
  • adaptation by modeling future climate impacts and changing company operations and strategy and
  • reductions in overall greenhouse gas (GHG) emissions.

Characteristics of Climate Change Leaders

Climate change leaders excel in key areas of climate innovation including

  • technological advances in fuels, equipment and emissions monitoring
  • managing exposures to the impacts of climate change and
  • creating efficiencies in energy use, business processes and transportation.

Leading companies are also innovating through cross-industry collaborations, employee incentives and unique ways of embedding innovation as part of their core business.

Financial Performance of Climate Change Leaders

Maplecroft has found that companies that are climate change leaders also deliver higher financial performance (measured as five-year return on equity, based on Bloomberg data). This is confirmed by the performance of the Maplecroft CIIs, which since their launch in January, continue to out-perform the Standard and Poor’s 100 by up to 3.5%. The CIIs faired even better when compared with other well-known climate related indexes, out-performing the HSBC Global Climate Change Benchmark by up to 8.7% and the Royal Bank of Scotland Climate Change & Environment Index by up to 25.3%.

Professor Alyson Warhurst, CEO of Maplecroft, said “The CIIs are a valuable tool for investors looking to pick winners, as they identify the most resilient, most innovative and best positioned companies to gain competitive advantage in the new low-carbon economy.” Furthermore, the CII findings demonstrate an opportunity for businesses across all sectors to distinguish themselves in terms of their climate innovation efforts as a means of strengthening reputation and building shareholder value.
