Meet Ampaire. This California-based start-up is one of the top 25 nominees of the Postcode Lottery Green Challenge 2018. Ampaire tackles two of the biggest problems in air travel: high operating costs and environmental impact.

The company specialises in large-scale ecosystem restoration through a data-driven approach to reforestation. Using drone and satellite imagery to first map landscapes, they employ automated drones to shoot biodegradable seedpods into drylands, wetlands - and everything in between. CEO Susan Graham explains how our global net loss of trees calls for a scalable solution, and how BioCarbon Engineering is meeting that challenge.

Meet My Dream Home. This Cambodian start-up is one of the 25 nominees of the Postcode Lottery Green Challenge 2018. In the capital Phnom Penh, rural-urban migration sees millions seek opportunities for education and employment. But a lack of affordable housing sees tenants sharing the smallest of spaces, and families forced apart. Kongngy Hav, founder of My Dream Home, aims to solve Phnom Penh’s housing crisis, brick by brick: made from compressed earth, his interlocking ‘LEGO’ blocks are cheap to produce, easy to assemble and - for those struggling to get on the housing ladder - life-changing.

Meet Aislatum. This Mexican start-up is one of the 25 nominees of the Postcode Lottery Green Challenge 2018. Founded in 2013, Aislatum aims to reduce climate change by cooling cities. The start-up has developed a paste that, when applied to rooftops, reduces buildings’ internal temperatures by up to 12°C. After a series of pivots, Aislatum is currently developing its product into a transport-friendly powder, which not only blocks the sun, but also functions as a waterproof coating. Having treated some 50,000sqm of rooftops in Mexico, founder Simon Galico chatted to us about how he hopes to expand the business, and in doing so, reduce energy consumption.

We spoke with co-founders Raj Madangopal and Mani Vajipey about how they’re changing the way brands think about recycled plastic in India.
