Sustainability is more than just a buzzword

The first and most challenging step to creating a sustainable business travel program is knowing where to start and what information you can rely on. To reduce travel demand and overall emissions, you need robust reporting to create a data-driven strategy.

Advito’s sustainability experts spent 18 months reviewing and evaluating different reporting methods to create our own proprietary methodology to calculate business travel emissions – GATE4.

Global Analytics for Travel Emissions

The “4” represents both the four categories where the methodology can be applied – air, hotel, rail, and car – and the goal to reduce global emissions by a factor of four by 2050 to mitigate the worst effects of climate change.

Reduce your travel program’s environmental footprint

To get a holistic picture of your total trip emissions, it’s not enough to just look at your air program. GATE4 is the first methodology to provide robust reporting on across air, hotel, rail, and car, on a global and market level.

GATE4 also takes into account multiple components not included in standard carbon reporting, such as country-level electricity mix and carbon intensity, passenger to freight ratios, aircraft type, hotel eco-labels, amenities, rail operators’ individual sustainability initiatives, and more.

With this data at your fingertips, you can create the right traveler-facing communications to keep them engaged in achieving your goals, whether that’s by using merchandising strategies to shift share to more sustainable suppliers or educating travelers on policy changes.

Set Science-Based Sustainability Targets

Take your strategy beyond simply offsetting emissions and develop a clear roadmap to reduce your footprint and contribute to the health of the planet. GATE4 is certified under the ISO 14000 series – the world’s most widely recognized environmental management standard. This means our emissions reporting figures can be included in annual financial reporting as recognized carbon calculations and be used to create science-based sustainability targets.

Working towards significant emissions reductions can also lead to dollar savings. For one of our clients, use used GATE4 data to determine that by shifting half of their volume to a more sustainable hotel in one of their top markets, they could save up to 119,000 kg of CO2 and $163K.

Meeting the ISO requirements provides independent validation, verification, and credibility by reassuring internal and external stakeholders that Advito’s carbon footprint methodologies are accurate, robust, and compliant with internationally-recognized GHG measurement and reporting standards.”
