Proactive approach to environmental sustainability

In 2018 Inmarsat achieved a CDP (formerly known as the Carbon Disclosure Project) score of B, maintaining our performance from the previous year and demonstrating that we are managing our environmental impact, as well as climate change related business risks and opportunities.

Although the direct activities of the Group are judged to have a low environmental impact, we understand that unless urgent action is taken to limit global temperatures to 2C (35.6F) above pre-industrial levels, climate change presents significant and systemic risks. We support the recommendations of the Task Force on Climate-Related Financial Disclosures (TCFD) and will look to continue to develop transparent reporting around climate-related risks and opportunities for our business.

Within our annual CDP response we provide details on Inmarsat’s substantive regulatory, physical and reputational risks and opportunities relating to climate change. For example, rising sea levels as a result of climate change could impact our satellite access stations which are located at strategic points around the world and act as traffic gateways connecting customers using the Inmarsat satellites to terrestrial networks. To manage this risk, we have established site selection due diligence processes which incorporate climatic geographical considerations.

Looking beyond our direct climate impact, we are working with our sustainability partner, Carbon Credentials, to quantify emissions from our indirect (Scope 3) activities, with the ambition of engaging with the suppliers and customers in our value chain to set meaningful emissions reduction targets. This work feeds into our ongoing programme to set a science-based emission reduction target in line with the UK’s commitment under the UN Paris Agreement.

Mitigating space debris

As a satellite operator, Inmarsat has adopted the highest industry standards for mitigating space debris, including end-of-life graveyard manoeuvre plans for the disposal of satellites when they reach the end of their commercial life.

Our satellites are engineered to have life spans of at least 15 years, although our longest-serving spacecraft, Inmarsat-2 F2, was in service for 23.8 years before being deorbited in 2014, in full compliance with the relevant International Telecommunication Union (ITU) standards.

We operate our satellites in geosynchronous orbit, which is approximately 36,000km above the Earth. This orbit has significantly less debris than a low earth orbit (approximately 700km), where several MSS operators have their satellite constellations.

We are a founding member of the Space Data Association (SDA), along with satellite operators Intelsat, SES and Eutelsat. By sharing data critical to the integrity of the space environment, we aim to make space operations safer and more reliable.
