Performance

Outside of these formalised processes, Antin also organises regular events to discuss and engage on climate change related topics with its portfolio companies. For instance, in 2021, Antin organised a cross-portfolio ESG seminar which included a presentation from external experts on material climate change-related topics and the impacts of COP26, as well as a presentation from one of Antin's portfolio companies on its recently launched net zero strategy. This seminar was attended by representatives from 11 of Antin’s portfolio companies. Given the growing importance of the climate emergency, Antin has also decided to take commitments with regards to its investment strategy. For several years, Antin has maintained exclusion criteria for coal-based activitie and has more recently decided to exclude midstream energy from any new investments going forward. As a result, its current portfolio has limited exposure to fossil fuels (please refer to “ Antin’s portfolio companies ”, pages 12 and 13 of this document, for further details on our portfolio companies’ sectors and activities). Antin has also set specific targets related to carbon footprint assessments and carbon emissions reduction plans for its Mid Cap Fund I companies, as part of an ESG-linked equity bridge facility it secured for the Fund. Moreover, Antin is currently raising its first Next Generation (NextGen) Infrastructure Fund, which will invest in the energy transition, environmental and green mobility, among other sectors, furthering Antin's commitment to businesses that can accelerate progress towards a net zero future. Some of Antin’s portfolio companies have already implemented ambitious emissions reduction strategies and roadmaps, and Antin works closely with them to support their efforts. Carbon reduction and climate change mitigation across the portfolio is a key ongoing workstream, with new frameworks being developed to homogenise and harmonise practices and set ambitious targets within the portfolio going forward. POWERING A NET ZERO FUTURE WITH VICINITY ENERGY Boston-based district energy company Vicinity Energy has committed to achieving net zero carbon emissions for all its operations by 2050. The company's approach is multi pronged, consisting of electrifying operations, switching out traditional fuel for renewable alternatives, and purchasing carbon-free energy. Thus far, Vicinity has successfully implemented biofuel at operations in Philadelphia and Boston and, in 2021, purchased roughly 10,000 MWh of emissions-free power. In 2022, the company will pursue its efforts by installing an electric boiler at one of its Boston plants. Antin is actively working with Vicinity to help formalise a roadmap with additional targets on the pathway to net zero. Equally, Vicinity has been able to share its efforts with the rest of Antin’s portfolio, presenting on its net zero strategy at the annual ESG Club meeting held in December 2021. CASE STUDY
