The climate around us is changing fast. Today we see the effects of global warming and deforestation on a regular basis. Irregular rains, floods and scorching heat in some regions of the world are some of the well-known effects of global warming. 

It's high time we consider the environment in the decisions we make. Each one of us must take collective steps to decrease our carbon footprint. By jam-packing our homes or building with insulation, we can reduce our carbon footprint to some extent.

But that alone is not enough. The only way to combat global warming is to plant more trees and that is what we intended to do when we partnered up with Ecologi. Ecologi empowers you to tackle climate change by planting trees.

How? Let us explain

When you Buy Insulation Online, we plant a tree in your name for free. After extensive research, Ecologi has carefully shortlisted a few varieties of plant species that have a maximum positive impact on the environment. In most cases, it is the mangroves. However, crop-yielding seeds are sown in areas where Ecologi's planting projects are taking place at the time.

The seeds are watered, nurtured and cared for by the locals. Therefore, by purchasing insulation online from us, you offset your carbon and make jobs for the local workers. Your trees grow to protect the biodiversity in the area and increase the green cover. The fruits and flowers produced by your tree will eventually become a source of livelihood for the local population.

At the end of every order, we send you an image of your saplings. We also share a link with you wherein you can see your tree grow whenever you feel like it.

Buy Insulation Online have been partners with Ecologi for a couple of years now, and we are proud to have planted around 1000+ trees so far.
